Recent international developments — including the conclusion and entry into force of the Paris Agreement and the high-profile Urgenda case, in which the Dutch government was sued over its inadequate targets for reducing emissions of greenhouse gases — have sparked interest in the possibilities for exploring new avenues of strategic climate change litigation in Australia. Australia already has a substantial body of decided climate change cases. To date, most have involved administrative challenges to projects under environmental laws in order to have climate change impacts taken into account. While this ‘first generation’ of cases has achieved significant results, there is increasing interest in the environmental advocacy and legal communities in taking forward a ‘next generation’ of cases that have a broader focus on holding governments and corporations directly accountable for the climate change implications of their actions. This article is the first to explore the contours of such next-generation climate change litigation in Australia, including the drivers for these lawsuits, the potential legal avenues by which they might be brought, and likely enablers and barriers. Rather than abandoning first-generation challenges — which have targeted Australia’s principal sources of greenhouse gas emissions such as coal-fired power stations and coal mines — we argue that the most fruitful strategy for future climate change litigation in Australia is likely to be one that continues to advance lower risk cases building from the base of existing litigation, while simultaneously attempting novel approaches. If sufficient resources existed, such an approach would have the benefit of allowing for more likely wins, paired with high-profile innovation that might capture the public imagination and maximise the potential for significant policy and regulatory impact.
This is an opportunity to be bold spirits rather than timorous souls and provide a lead for the common law world.
Strategic climate change litigation generally involves the use of the law and court action to advance beneficial outcomes for addressing climate change. Climate change litigation in Australia has a long and proud history. The first climate change case of Greenpeace Australia Ltd v Redbank Power Pty Ltd (‘Redbank Power’) was decided in 1994 by Pearlman CJ of the Land and Environment Court of New South Wales (‘NSWLEC’). That case involved a challenge by Greenpeace, supported by the Environmental Defenders Office NSW (‘EDO NSW’), to a government decision approving a new coal-fired power station on grounds including the potential for the power station to emit greenhouse gases (‘GHG’) and contribute to climate change. Redbank Power has served as a model for much of the ensuing climate change litigation in Australia over the subsequent 20 years. Like the Redbank Power case, this ‘first generation’ of Australian climate change litigation has largely concerned administrative challenges to government decision-making under planning and environmental legislation, seeking to incorporate climate change within the scope of decision-making on a project, generally as an aspect of ensuring the application of concepts or principles of ecologically sustainable development (‘ESD’). One stream of this litigation has targeted GHG emissions reduction (mitigation) by challenging coal-fired power and coal mines. A second ‘adaptation’ stream has focused on climate change impacts for development, such as the risks posed by sea level rise and increased
The achievements of the first generation of climate change litigation in Australia have been significant in a number of ways. Over time — in an incremental and iterative fashion — these cases have consolidated the practice of including climate change considerations in environmental impact assessment undertaken for projects with substantial GHG emissions or the potential to be impacted by climate change consequences such as sea level rise. More broadly, the cases have raised awareness of climate change as a key environmental issue in the public, business, professional and government sectors.
Nonetheless, climate change litigation in Australia has not achieved the transformative impact seen in other countries. Australia, for example, has not had a Massachusetts v EPA moment equivalent to that of the US. The US Supreme Court’s decision in that case required the Environmental Protection Agency (‘EPA’) either to regulate motor vehicle GHG emissions or better justify its refusal to do so. On the basis of this decision, the Obama administration found GHG emissions cause pollution that threatens public health and welfare, and introduced regulations to limit such emissions from motor vehicles and stationary sources, such as power plants. A number of these regulations have been slated for repeal by the Trump administration, which in turn may open up new litigation pathways.
Australia also has not seen the kind of common law actions that have been brought in the US, alleging government or corporate responsibility for likely climate change damage on the basis of actions in nuisance, negligence or under the public trust doctrine. Although the US Supreme Court significantly limited federal public nuisance claims on the grounds that such actions are displaced by Congress’s grant of authority to the EPA under the Clean Air Act, that avenue could reopen if the Republican Congress — without the veto constraints under President Trump that President Obama provided — eliminates that authority. Efforts to use the public trust doctrine in the United States achieved an important milestone in November 2016, when an Oregon district court held in Juliana that constitutional due process and public trust claims against the federal government for its failure to address climate change sufficiently had been adequately alleged to survive a motion to dismiss. While the ultimate resolution of this case on the merits remains unclear, it provides an important model for how a public trust claim can be framed in the climate change context.
Courts in other jurisdictions issued ground-breaking decisions around governmental duties to address climate change in the lead-up to the 2015 international climate negotiations in Paris. In June 2015, the Hague District Court in the Netherlands handed down a decision finding that the Dutch government’s 2020 GHG emissions-reduction target was inadequate in light of international climate science and international climate policy, and ordering the government to increase its target in fulfilment of a duty of care to its citizens to safeguard them from the effects of climate change. Four months later in September 2015, the Lahore High Court in Pakistan held that the national government violated its citizens’ fundamental rights through delays in implementing the country’s climate change adaptation policy framework. Greenpeace Southeast Asia, together with local groups and individuals, also filed a petition that same month, which the Philippines Commission on Human Rights is currently considering. The petition claims that major contributors to climate change, including the 50 largest fossil fuel companies, are violating Filipinos’ fundamental human rights. That December, the international community concluded a decades-long negotiation process to adopt the 2015 Paris Agreement with the central goal of holding global average temperature rises to ‘well below 2°C’ and pursuing efforts to limit temperature rises to no more than 1.5°C.
In light of these international developments, there has been increasing discussion in the Australian environmental advocacy and legal communities of the potential to emulate recent overseas climate change lawsuits with a ‘next generation’ of climate change litigation. While there is a high level of interest in pursuing such cases, many questions remain about what exactly next-generation climate change litigation in Australia might involve. What causes of action may be pursued and which might offer the best prospects of success in an Australian legal context? What are the potential enablers of, and barriers to, bringing next-generation climate change cases? More fundamentally, is there a need for a next generation of novel climate change lawsuits or are efforts to launch such cases better viewed as an extension of first-generation litigation, building on the strategies and lessons developed through that experience? This article provides the first comprehensive analysis of
these questions in an Australian context, with the aim of beginning, and informing, further conversations around the future of climate-change litigation in Australia.
Following an examination of ways of defining ‘next-generation’ climate change litigation, Part II of the article considers the impetus for discussions about initiating such cases in Australia. It identifies key drivers, including recent high-profile international cases, the conclusion of the Paris Agreement, advances in climate change science, and a changing business culture regarding climate change risk. Part III then turns to the question of how next-generation climate change litigation might be taken forward in an Australian context. It canvasses potential pathways for next-generation cases, as well as their relationship to past and ongoing first-generation litigation. A critical question that arises in this regard is whether next-generation climate change cases should displace or supplement first-generation litigation. Part IV considers potential enabling factors and hurdles for next-generation climate litigation that are shared with other types of public interest environmental litigation, but which may manifest in different ways in next-generation cases. These include: procedural questions relating to getting a case before the courts, such as standing, case funding and costs risks, securing legal representation and selecting an appropriate forum for the case; evidentiary aspects once the case is in court such as issues of showing attribution and causation, and the presentation of climate science in the courtroom; and new opportunities for advocacy organisations to partner with companies, investors and others who have aligned interests in clean energy transition or adaptation planning.
Part V concludes with a discussion of the competing strategic considerations that are likely be in play as groups work to shape the next generation of climate change litigation.
Unlike many other countries, Australia already has a significant history of climate change litigation. The only country that has had more cases is the United States. Therefore, in discussing next-generation Australian climate change litigation, environmental advocates and lawyers are not talking about how to start a climate change justice movement in this country, but rather whether and how that movement needs to be revitalised, potentially through bringing different sorts of lawsuits to those that have characterised the first generation of cases. This part considers how next-generation climate change litigation might be defined. It then discusses some of the key drivers that have generated momentum for investigating next-generation lawsuits, or at least, taking a fresh look at climate change litigation in Australia and how its strategic impact might be maximised.
A central concern in assessing the potential for a next generation of climate change litigation in Australia is an understanding of what such litigation might involve. This is not a straightforward question to answer. For a start, climate change litigation itself can be difficult to define. As Peel and Osofsky have discussed in previous work on this topic, a useful way of conceptualising climate change litigation is as a series of concentric circles (see Figure 1). At the core are cases that directly engage questions of climate change law and climate science, for example, corporate responsibility for the environmental impacts of GHG emissions. As we move towards the periphery of the circles, climate change tends to feature less in the arguments put before a court, even if addressing the problem of climate change remains one of the key motivators for those bringing the cases. For the most part, ‘strategic’ climate change litigation — that brought with the aim of producing policy or social change with respect to the issue — involves litigating ‘core’ climate change cases.
Litigation with climate change as central issue
Litigation with climate change as peripheral issue
Litigation with no specific
climate change framing but implications for mitigation or adaptation
(eg fracking cases)
Litigation with climate
change as a motivation but not raised as an issue (eg cases against coal brought on environmental grounds)
Figure 1: Conceptualising Climate Change Litigation
The second question that then arises is what is next-generation climate change litigation? This necessarily involves some notion of what is encompassed within first-generation climate change jurisprudence and how next-generation cases differ from what has gone before. In Australia, most climate change litigation to date has pursued a standard statutory pathway, albeit with variations depending upon the legislation under which a case is brought. These cases have generally involved challenges to administrative decision-making (either judicial review or merits review) under planning or environmental legislation raising questions of both climate change mitigation and adaptation. There have also been a number of cases brought by the Australian Competition and Consumer Commission (‘ACCC’) relating to misleading ‘green’ product claims. In addition, in the broader penumbra of climate change litigation — cases in the outer circles depicted in Figure 1 — there has been an increasing number of cases focusing on issues such as the use of hydraulic fracturing (‘fracking’) for coal seam gas exploitation, access to information, and class actions for damage from extreme weather events such as major floods and bushfires. However, in the main, the core of first-generation cases are lawsuits that have focused on individual, emissions-intensive projects, which have been brought under environmental statutes,
and have sought to improve governmental decision-making regarding
By contrast, what we have termed next-generation litigation in this article represents a shift away from the project-level focus and environmental statutory basis of earlier cases. Next-generation cases are founded on an accountability model whereby legal interventions are designed to hold governments and corporations directly to account for the climate change implications of their activities. Lawsuits in this vein often embrace a broader range of parties pursuing climate change-related litigation with a different range of motivations than those of first-generation litigants. In particular, parties may not be pursuing actions to advance beneficial outcomes for addressing climate change as a primary goal. Even if they are driven by commercial motives, though, the end result is potentially beneficial to addressing climate change where cases foster better consideration of climate change risks in business decision-making and the eventual uptake of clean energy practices. This trend is particularly apparent in the growing interest in lawsuits brought by shareholders and investors against companies and directors over inadequate disclosure of climate change risk. But it is equally the case in emerging US public trust lawsuits (involving youth plaintiffs arguing on behalf of future generations’ interests) or human rights cases (highlighting the linkage between violation of rights protections and environmental harms, including climate change).
Another difference that is evident between past cases and proposed next-generation cases is the move away from using only administrative law avenues under environmental legislation to also exploring causes of action found in the common law or in other areas of law outside of the environmental field. This broadening of the scope of legal avenues considered for climate change litigation reflects both concerns with the adequacy of administrative review (particularly judicial review) as a tool for effecting transformative legal change in the climate change arena, as well as a desire to provide stronger foundations for duties of care on the part of governments and corporations to address climate change. It is important to emphasise, however, that the legal avenues being considered as a basis for next-generation climate change litigation are not themselves novel causes of action. Indeed, one of the ironies of next-generation litigation is that legal advocates are often looking to the past to shape the litigation of the future. By turning to old legal precedents, well-established mechanisms in other areas of law, and ‘ancient’ common law doctrines such as the public trust, the architects of next-generation climate change litigation seek to repurpose these existing legal tools for new climate-related ends.
Our starting point for this consideration of next-generation cases is the perception — which has been at the forefront of recent discussions of climate change litigation within the Australian environmental advocacy community — that recent international legal developments have created impetus or opportunities for thinking about strategic climate change litigation in new ways. The Urgenda case — which generated significant media attention in Australia as in other countries — is often cited as an important development in this regard. The legal prospects of an Urgenda-style case in Australia may be significantly lower given differences between the relevant provisions of the Dutch Civil Code relied on by the Urgenda plaintiffs and tortious causes of action in Australia’s common law system. Nonetheless, the Hague District Court’s decision on 24 June 2015 undoubtedly inspired and energised the Australian environmental advocacy community regarding the potential for climate change litigation to achieve policy change. Environmental advocacy organisations, such as the Environmental Defenders Offices (‘EDOs’), have been deluged since the Urgenda decision with enquiries about the potential for similar cases in Australia, with interest from both prospective claimants and funders. More broadly, it is evident that the Urgenda case put climate change litigation on the map for a wider range of actors than those usually engaged in first-generation cases, including different constituencies of litigation funders and barristers. This has encouraged a fresh perspective
on possible avenues for bringing climate change cases, especially within the legal community.
Another pivotal development that has helped to re-enliven interest in climate change litigation in Australia is the Paris Agreement concluded by 195 nations at the end of 2015. This treaty entered into force on 4 November 2016 and will come into effect from 2020. On 10 November 2016, Australia announced its formal ratification, joining over 100 other countries that are now party to the treaty. Australia’s 2030 emissions reduction pledge — of a 26–8% cut in emissions from 2005 levels — is widely considered inadequate, and there are also serious questions about the capacity of existing federal climate change measures, such as the Emissions Reduction Fund (‘ERF’), to meet even that weak target. Australia’s participation in the Paris Agreement is thus likely to increase domestic and international scrutiny of its actions on climate change.
That said, President Trump’s June 2017 decision to have the US withdraw from the treaty and abandon domestic federal implementation efforts such as the Clean Power Plan poses a significant challenge. The US measures were expected to contribute around 20% of pledged global GHG emissions reductions. The US government’s submission of a formal notice of its intention to withdraw from the Paris Agreement followed in August 2017. However, in accordance with art 28 of the treaty, this process will not be complete until November 2020. As this process unfolds, it remains unclear whether the US will ultimately stay in the Paris Agreement but seek to ‘downgrade’ its emissions reduction pledge, as well as how such action or complete withdrawal by the US might affect the ambition of other countries’ climate actions.
If the Paris Agreement continues, with or without the US, it offers limited direct prospects for climate change litigation to enforce its requirements, which are mostly directed to states parties’ preparation, implementation and review of their ‘nationally determined contributions’ (‘NDCs’) to the global climate change response. In particular, the Paris Agreement does not provide specific legal causes of action that could be pursued by individuals or groups to enforce Australia’s obligations under the Paris Agreement. Moreover, the Australian government’s initial NDC for the period 2020–30 indicates that no new legislation will be enacted to give effect to Australia’s obligations under the Paris Agreement, which will instead be achieved relying on existing policy measures such as the ERF. Despite these limitations, the Paris Agreement provides a goal for international climate change action and an approach to achieving that goal that is considerably clearer and more transparent than previous agreements, which could help bolster claims in litigation brought using other legal avenues.
Two provisions of the Paris Agreement are potentially pertinent in this regard. The first is art 2, which sets out its overarching objective of strengthening the global response to the threat of climate change by, inter alia,
[h]olding the increase in the global average temperature to well below 2°C above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5°C above pre-industrial levels, recognizing that this would significantly reduce the risks and impacts of climate change.
This ‘long-term temperature goal’, as it is referred to in the Paris Agreement, provides guidance on the maximum permissible global temperature rise considered acceptable by the international community. Working backwards from the 2°C (or 1.5°C) target, scientists can calculate the remaining global carbon budget to stay within that temperature threshold. Although the Paris Agreement does not specify parties’ individual shares of that budget, it does provide for a five-yearly ‘global stocktake’ to assess the collective progress made by NDCs in achieving the treaty’s goals, which is to be undertaken ‘in the light of equity and the best available science’. These provisions articulate some broad parameters by which courts might judge the adequacy of a government’s proposed emissions reduction actions or the environmental significance of a particular emissions-intensive project. While the art 2 objective is not directly enforceable in Australian law, judges may take judicial notice of the new global temperature goal as part of their assessment of factual evidence in a case. For instance, an understanding of the Paris Agreement’s long-term temperature goal and how it relates to global carbon budgets could inform judicial evaluation of evidence regarding factual questions such as how much a particular project or a particular entity’s activities contribute to GHG emissions and climate change.
A second key provision of the Paris Agreement is art 4.1, which
[i]n order to achieve the long-term temperature goal set out in Article 2, Parties aim to reach global peaking of greenhouse gas emissions as soon as possible, recognizing that peaking will take longer for developing country Parties, and to undertake rapid reductions thereafter in accordance with best available science, so as to achieve a balance between anthropogenic emissions by sources and removals by sinks of greenhouse gases in the second half of this century, on the basis of equity, and in the context of sustainable development and efforts to eradicate poverty.
This provision equates to a call for global action to achieve ‘net zero emissions’ in the second half of the century — a goal that will only be attainable with a phase-out of fossil fuel energy sources. Although art 4.1 does not provide a precise timeline for this phase-out, it clearly signals a finite lifespan for the fossil fuel economy globally. As such, it provides added impetus for domestic decision-making to move away from the approval of emissions-intensive projects. Again, art 4.1 does not provide domestic litigants with any direct legal pathway to hold governments or corporate actors accountable for climate change implications of their activities. However, as with art 2, it may aid plaintiffs in establishing factual points such as the sustainability of continued fossil fuel development.
Another potential impetus for a renewed interest in climate change litigation is the increasing sophistication of climate change science. The most recent assessment by the Intergovernmental Panel on Climate Change (‘IPCC’) articulates the strong scientific consensus on the existence and human causes of climate change, as well as the likely nature of its impacts. In Urgenda, the Hague District Court extensively referred to IPCC reports to ground its understanding of the GHG emissions reductions required from developed countries in order to prevent dangerous anthropogenic global warming. Australian cases — even in jurisdictions that have in the past displayed
open scepticism towards climate change science — have increasingly embraced the international scientific consensus on the causes and effects of
What remains more challenging is linking specific projects with specific impacts, or from an adaptation or loss and damage perspective, linking specific weather events with specific harms. However, scientific knowledge on ‘event attribution’ is rapidly improving. While it is still not possible to say definitively that a particular severe weather event was ‘caused’ by climate change, scientists are increasingly able to ‘estimate how much more or less likely the event has become due to human influences on the climate’. For some climate change impacts, such as those related to increased temperatures (eg heat waves, coral bleaching, sea-level rise), the scientific understanding of causation is far more advanced than for others.
Advances have also been made in research examining the specific contribution of fossil fuel companies to global GHG emissions and climate change. Richard Heede’s pioneering work examining the share of global GHG emissions attributable since industrialisation to so-called ‘carbon major’ companies is one example. This work formed the basis of the above-mentioned petition accepted by the Philippines Commission on Human Rights in December 2015 alleging the responsibility of carbon majors for climate change impacts on Filipinos’ human rights. Another example is the use of climate scientists’ research on carbon budgets and climate change impacts. Scientists, such as Professor David Karoly and Dr Malte Meinshausen of the University of Melbourne, have given evidence as expert witnesses in several Australian challenges to coal mining projects regarding the contribution to climate change made by a particular mine proposal — evidence which assists in determining the significance of a project’s environmental impacts.
The Paris Conference was notable for the constructive engagement of business interests and the private sector in a way not previously seen in other international climate change negotiations. This engagement is evidence of an ongoing change in business culture around climate change risk as more and more companies and investors take the issue seriously and begin to take initiatives to transition to clean energy sources. Not all companies have embraced the need to disclose and act on climate change risk (indeed, some companies in the fossil fuel sector remain very resistant to this view and may be emboldened by the US Trump administration and its expansion of coal, gas and oil production). Nonetheless, there has been a gradual shift to view climate change as a material business risk. Various efforts have underpinned and strengthened this shift, including the development of international standards by the Financial Stability Board’s Task Force on Climate-Related Financial Disclosures, and investigations launched by state Attorneys General and the Securities and Exchange Commission (‘SEC’) into alleged misleading and deceptive disclosure practices of major coal and oil companies in the United States. In Australia, key developments have included: the issue of an opinion from a leading Sydney barrister, Noel Hutley SC, on the obligations of company directors to consider and act on climate change risk; and the announcement by Australia’s financial regulator, the Australian Prudential Regulation Authority, that it intends to monitor the consideration and disclosure of climate risks by banks, insurers, superannuation funds and wealth managers given the financially material and foreseeable risks posed to Australian businesses, with potentially system-wide implications for the financial system.
This changing business environment raises possibilities for pursuing a range of new climate change litigation pathways using corporations law mechanisms. For environmental advocacy groups, these shifts also open up new possibilities both for partnering with investor and shareholder groups or leading companies that wish to forward policy development and corporate action, and for identifying laggards who may be the target of litigation efforts.
Given the coalescence of factors described in the previous part, this may well be the opportune moment for thinking about a next generation of climate change litigation in Australia. In the United States, which has led the climate change litigation movement globally and inspired many Australian efforts, the actions of President Trump’s administration may also usher in a new era of pro-regulatory litigation as environmental advocates challenge his regulatory approaches and explore alternative avenues under constitutional and common law as statutory avenues are closed down. As noted in the introduction, the US Supreme Court’s blocking of the federal public nuisance pathways, in particular, was premised on the Clean Air Act’s regulatory authority displacing that approach. However, if the Republican Congress eliminates that regulatory authority, public nuisance lawsuits might gain a new viability in the United States that could potentially provide impetus for Australian experimentation. Similarly, the success thus far of the public trust claims in Juliana provides a potential model for Australian advocates to frame a case using
While there is considerable enthusiasm for new approaches, how this new-generation climate change litigation might be progressed, including what legal causes of action might be used, are issues that have not been systematically explored. The embrace of a next generation of litigation also raises questions as to how such cases relate to earlier ones. In particular, an ongoing debate in the environmental advocacy community is whether next-generation litigation should be pursued in the alternative to, or alongside, cases that build on strategies or lessons from first-generation cases. This part considers these questions in order to provide guidance on strategies for taking forward a next generation of climate change litigation.
Lawyers and advocacy organisations involved in climate change litigation have generally taken a creative approach in exploring the possibilities for strategic lawsuits to advance action on climate change. Nonetheless, unlike the United States, Australia has not seen cases pursuing common law, rights-based or constitutional pathways, including actions in negligence, nuisance or public trust, or raising issues of human rights violations. Similarly, beyond the ACCC cases, there have been only limited efforts to date to harness corporate law mechanisms to forward climate change action.
In planning a next generation of climate change litigation in Australia,
lawyers and advocates have envisaged a suite of lawsuits pursuing different
legal avenues or defendants than have been tried in the past, and encomp-
assing a broader array of claimants with increasingly diverse interests. There
are a range of potential avenues that are currently receiving considerable attention, including:
• claims in negligence against government or corporate actors for a breach of duty of care to protect citizens from climate change impacts;
• actions under corporations law, suing companies or their directors, auditors or advisors for failures to disclose adequately or act appropriately on climate change risks to their businesses;
• human rights, indigenous rights or (environmental) constitutional rights claims asserting that failures of mitigation or adaptation violate rights protections; and
• claims based on ancient common law notions of the public trust, perhaps along the lines of Juliana, arguing that this doctrine requires the protection of natural resources (coastal wetlands, water resources, the atmosphere) for the benefit of the public.
The discussion in the following sections focuses on the first two avenues,
which are arguably the most likely to be pursued in Australia in the near future. We focus on identifying some significant considerations and developments, rather than engaging in a detailed, substantive assessment of the possibilities of success. The final section addresses the question of how the emergence of a suite of next-generation cases might potentially interact with first-generation litigation.
As noted above, the success of Urgenda in the Netherlands in 2015 has prompted substantial consideration of the potential to bring a similar action in negligence against government or corporate actors for a breach of duty of care owed to Australians (or to a particular, vulnerable group) to safeguard them from harms caused by climate change.
The Urgenda case was brought by a Dutch NGO, the Urgenda Foundation (‘Urgenda’),which also acted on behalf of 886 Dutch citizens. The case centred on the question of whether the State of the Netherlands had a legal obligation towards Urgenda (and Dutch citizens more broadly) to pursue more ambitious GHG emission reductions. Urgenda argued that the Netherlands’ official emissions reduction target at the time (which was likely to result in a 14–17% reduction on 1990 emissions levels by 2020) was unlawful because it was insufficient to prevent foreseeable harm.
While Urgenda pursued a number of different lines of argument in the case (including alleging breaches of constitutional rights under the Dutch Constitution, of human rights under the European Convention on Human Rights, and of the Netherlands’ obligations under international and European climate change law), the Court’s decision centred on the general negligence provisions of the Dutch Civil Code.
The Court’s reasoning in finding that the State of the Netherlands owed a duty of care to Urgenda and had indeed breached this duty has been described and analysed in detail elsewhere. Our focus here is on the potential for a similar claim in negligence to be brought in a common law context, such as Australia. In contemplating an Australian Urgenda, local environmental advocacy groups are well aware of the lack of direct correlates between the civil code provisions noted above and similar doctrines in domestic tort law. As Baxter notes, ‘[m]any aspects of the claim in the Dutch context are simpler than they are in Australia because of the Dutch Civil Code’. In particular, the substance of the law of negligence is contained in just one provision, art 6:162, which is supported by the case law. Indeed, prior to the Urgenda decision, a number of Australian commentators had highlighted the significant doctrinal and practical difficulties of mounting a successful claim in negligence in Australia in relation to climate change harms, largely dismissing these claims as unworkable. It is useful here to survey these difficulties and reconsider them in light of the line of argument that was successfully taken in Urgenda, and the significant recent developments in climate science and climate change law and policy at international and domestic levels.
For these purposes, we focus on the detailed consideration of hypothetical potential actions in tort against corporate entities responsible for GHG emissions, which was undertaken by Abbs, Cashman and Stephens in 2012. In this piece, the authors foreshadowed a range of probable difficulties in establishing various elements of the claim and cautioned that ‘the legal context in Australia provides reasons for circumspection’. For example, they suggested that Australian courts would be reluctant to recognise a duty of care in situations where there is no direct or specific relationship between a defendant and plaintiff, but rather the defendant’s actions in emitting GHG to the atmosphere ‘with respect to the world at large’ have contributed (together with a multitude of other diverse entities over space and over time) to the harm experienced by the plaintiff. They add that even if a duty of care was recognised, proving a breach would be problematic as a plaintiff would be required to establish that a reasonable person in the position of the defendant should have anticipated not just the risk of climate change but also the risk of the particular harm to the plaintiff occurring as a result of climate change, and that the defendant should have taken precautions against that risk. Even if it could be successfully argued that the nature of the harm experienced was foreseeable, establishing that the defendant should have taken precautions to avoid that risk (essentially by ceasing to emit GHG) would likely be very difficult given the social utility of the activities which caused the harm (eg providing fuel for power generation) and the fact that these very activities have been long sanctioned by society. Further, Abbs, Cashman and Stephens argue that establishing factual causation presents near insurmountable barriers for potential tortfeasors due to the multitude and highly dispersed nature of the individual agents responsible for the emission of GHG to the atmosphere and the consequent difficulty of establishing that the negligence of one particular entity was a precondition to the realisation of particular climate change impacts. They consider the limited exceptions to the ‘but for’ causation test and explore situations where courts have been prepared to consider a material contribution to the loss or damage as being sufficient to establish causation. However, even if some level of material contribution to causation of harm could be successfully established in a climate change context, Abbs, Cashman and Stephens submit that it is unlikely that an Australian court would conclude that it is ‘appropriate’ to attribute liability and award damages for the emission of GHG and associated harm.
Abbs, Cashman and Stephens’s consideration was framed in relation to suing a corporate entity for loss or damage experienced as a result of climate change. This focus on compensating harms already experienced by a plaintiff is the traditional path of negligence law in common law jurisdictions. However, in Urgenda, the negligence claim was not directed to compensating loss and damage ex post, but rather to preventing foreseeable future harms. As such, the remedy awarded was not compensation, but rather a court order requiring the State of the Netherlands to take more action to reduce GHG emissions. Baxter argues that a claim in negligence against a governmental defendant along these lines is worthy of renewed consideration in an Australian context.
Baxter notes that negligence claims in Anglo-Australian jurisdictions have, until recently, only ever been successful where the primary remedy sought was damages. He argues, however, that seeking a remedy in equity in the form of an injunction to prevent future breach and damage occurring (either by enjoining the defendant not to breach their duty or ordering the defendant to take steps to prevent damage occurring) provides a more promising approach that would potentially bypass some of the difficulties in establishing breach and damage that were noted by Abbs, Cashman and Stephens. Baxter cites a recent decision of the Federal Court of Australia where a claim in negligence in an immigration context was brought on an entirely ex ante basis. In this case, the court was prepared to issue a remedy in equity against the governmental defendant in the form of an injunction to prevent the breach and anticipated damage. Essentially, Baxter argues that taking this novel approach to a negligence claim offers a higher chance of a court being prepared to award a remedy.
However even pursuing this approach, it would still be necessary to establish that a defendant owed a duty of care, for example, to take action to prevent dangerous climate change, and that the alleged breach of this duty would lead to the anticipated damage. The factual basis on which such a claim could be brought continues to improve due to a number of factors, such as: recent developments in climate change science, including the ability to attribute climate change impacts to GHG emissions and to calculate comparative contributions to global emissions; the growing body of international and domestic legal and policy instruments acknowledging the extensive threats posed by climate change and the concrete mitigation measures needed to minimise these risks (including the Paris Agreement); and the fact that the Australian government has consistently participated in and ratified international climate change treaties and has the authority and capacity to implement required mitigation measures.
Nonetheless, the experiences of first generation litigation in Australia, particularly in arguing causation, underscore the challenges that would-be litigants may face in launching an Urgenda-style action. For example, in the context of judicial review of decisions relating to particular fossil fuel projects (which have formed such a large part of first-generation climate change litigation in Australia), Australian courts have responded only slowly to scientific evidence and arguments put by claimants that the emissions related to a particular fossil fuel project will contribute significantly to cumulative global emissions and climate change impacts, and are therefore relevant when considering the environmental impact of a specific project. While there has been an incremental acceptance of these arguments and also the climate change scientific evidence over time, no Australian court has yet been prepared to refuse a fossil fuel project purely on climate change grounds. Often courts have fallen back on the ‘market substitution defence’ — that a particular project ‘will not have an impact on climate change, because if that proponent does not mine and sell coal, someone else will’. Similar difficulties would likely be encountered in arguing that Australia’s GHG emissions were a material contribution to the global problem of climate change sufficient to satisfy tests of causation.
Further, while the Hague District Court came to the conclusion in Urgenda that it would not be an intrusion on the separation of powers doctrine for the court to make an order requiring the government to take further action on climate change, Australian courts have tended to take a very restrictive view of their role with regards to ‘political questions’ or justiciability. Indeed, it is worth noting that the Urgenda decision has been appealed by the State of the Netherlands, and one of the primary grounds for appeal is that the District Court improperly interfered with the doctrine of the separation of powers. It is likely that similar arguments would also be a feature of any Australian litigation attempting to pursue the federal government over its weak emissions-reduction targets.
In other common law jurisdictions, such as the United States and more recently, the United Kingdom, both of which have similar albeit not identical corporations law regimes to Australia, litigation trends are emerging. Actions are increasingly brought against corporations and their directors for misleading disclosure of business risks associated with climate change and for related breach of directors’ duties arising from failure to disclose and properly account for these climate risks. These legal interventions are taking place under existing, general laws that require the disclosure of material business risks and which govern directors’ duties to a company and its shareholders. They are being initiated by regulators, by environmental advocacy groups, and increasingly, by shareholders claiming compensation for associated financial losses.
For example, in the United States, there has been a series of high-profile regulatory investigations into the disclosure practices of major fossil fuel companies, including Peabody Energy Corporation and Exxon Mobil. These investigations have been launched both by state Attorneys General under state laws prohibiting false or misleading conduct in connection with securities transactions, and at a national level by the SEC. In general terms, these investigations have alleged that the companies involved have misled shareholders by understating the severe potential impacts of climate change risk to their businesses. In November 2016, a shareholder class action was launched against Exxon Mobil and its directors, alleging that the company made false and/or misleading statements in relation to the value of its oil and gas reserves, leading to a material overstatement of the value of these reserves. Class members are seeking compensation for a drop in share value that occurred following the public reporting of the regulatory investigations into Exxon Mobil’s disclosure practices noted above. The emergence of this class action is particularly significant as it underscores the shift taking place to recognise climate change as a material consideration for business, rather than as a purely ethical, sustainability issue.
In a similar vein, in the United Kingdom, a leading environmental law NGO has recently submitted regulatory complaints to the Financial Reporting Council (‘FRC’), alleging that two major oil and gas companies have failed to disclose climate-related risks to investors. The complaints argue that the lack of any substantive discussion of climate change risks in the annual reports of these companies does not meet statutory requirements including: to provide ‘a fair review of the company’s business’; a proper account of ‘the main trends and factors likely to affect the future development, performance and position of the company’s business’; and a proper ‘description of the principal risks and uncertainties facing the company’. The claim is that the reports therefore prevent shareholders from assessing how the directors have performed their legal duties to promote the success of the company.
Given the similarities between US, UK and Australian corporate law regimes, such disclosure-focused actions may also be viable in Australia. Indeed, after considering the statutory provisions governing disclosure and director’s duties and the relevant case law, the legal opinion provided by Noel Hutley SC and Sebastian Hartford-Davis concludes that ‘[i]t is likely to be only a matter of time before we see litigation against a director who has failed to perceive, disclose or take steps in relation to a foreseeable climate-related risk that can be demonstrated to have caused harm to a company’. Specifically, the opinion confirms that Australian company and securities law requires companies to disclose material business risks to shareholders and to the market via annual reports and other continuous disclosure measures. It also opines that, increasingly, climate change is recognised as posing significant material risks to Australian businesses across all sectors, but particularly the resource, energy and finance sectors. Further, company directors under Australian corporations law are bound by legal duties, including to manage the interests of the company with due care and diligence. To fulfil these duties, directors should consider and disclose all material and foreseeable risks posed to their business: as the Hutley and Hartford-Davis opinion notes, the materiality and foreseeability of risks posed by climate change is increasingly acknowledged.
While there is a palpable excitement in many parts of the Australian environmental advocacy community about next-generation climate litigation approaches, strategic questions around the relationship between such cases and prior climate change litigation efforts remain unresolved. Some groups — such as the Victorian-based Environmental Justice Australia — have been actively involved in investigating next-generation litigation options as part of their commitment to ‘seek[ing] out new and innovative ways to tackle environmental problems’. Thus, one vision for next-generation climate change litigation is that it would constitute a break with the past and an opportunity to put litigation resources into new cases seen as more likely to offer prospects for transformative change.
However, equally a next generation of climate change litigation in Australia could coexist with ongoing efforts to build on and expand past and existing first-generation cases. Under this strategy, first generation-style cases would continue. For example, despite the lack of previous success in federal climate change cases, the Australian Conservation Foundation (‘ACF’) decided to appeal the Federal Court decision in the Adani Carmichael mine case — a case based on judicial review under the Environment Protection and Biodiversity Conservation Act 1999 (Cth) — as far as possible through the appeals process to try to clarify the requirements for consideration of ‘scope 3’ GHG emissions under federal environmental law. Public interest lawyers at the NSW EDO also foresee an important ongoing role for first-generation climate change cases. Their present litigation strategy involves embedding cases with a ‘core’ climate change focus within a broader program of related litigation that advances other goals relevant to climate change action, such as improving decision-making transparency, resisting fossil fuel projects including coal seam gas, and advancing necessary adaptation. This approach has the benefit of building upon a well-established Australian litigation tradition, and so may have a higher rate of success than more innovative approaches.
A ‘middle-way’ strategy would involve a combination of both first-generation and next-generation litigation, with the latter supplementing the former. Advocates would continue advancing lower risk cases that build from the base of existing litigation while simultaneously attempting novel approaches. If sufficient resources existed, such an approach would have the benefit of allowing for more likely wins paired with high-profile innovation that might capture the public imagination. For example, in the United States, the human rights petition and nuisance cases brought on behalf of Alaska Natives brought a great deal of public attention to climate change and their plight at the same time as statutory cases and challenges to coal-fired power plants achieved more formal success and direct regulatory impact. A middle-way strategy also offers the potential for a fruitful division of labour between different environmental advocacy organisations with differing missions and experience. Some groups with extensive first-generation litigation experience might continue primarily to pursue these efforts. Other groups could take forward next-generation litigation options. A key goal would be to ensure coordination between these efforts as far as possible so they form part of a coherent litigation strategy and do not cut across
As these options reinforce, how Australian groups approach next-generation climate change litigation is intimately linked with the question of its relationship to the first generation of cases. If one takes the view that these initial cases have been unsuccessful and unproductive, then next-generation litigation might be designed to displace these cases in favour of new, potentially more productive avenues. However, as indicated in Part I, in our view, the first generation of Australian cases, although not as transformative as many advocates might have wished, still have had a significant impact. This litigation has helped to build practices of consideration of climate change as part of ESD, has raised the public profile of the climate change issue, and has made both courts and litigators more accustomed to climate change arguments and climate science. Given these successes, the middle-way strategy of concurrently pioneering new legal causes of action for climate change purposes while expanding upon pathways that have been successful seems like the most productive approach.
As first-generation climate change cases in Australia have shown, litigation in this area faces some significant potential barriers. To be successful, these barriers have to be minimised and enabling conditions that favour successful outcomes maximised. This part considers key enablers of, and barriers to, climate change litigation that will help to shape the prospects for success of any next-generation cases. While these factors are also relevant for first-generation cases and public interest environmental litigation more generally, they are likely to manifest in different ways in next-generation litigation given the different causes of action being pursued. This part is divided into three sections that consider procedural aspects related to getting cases before courts, evidentiary aspects related to the presentation of cases in court and partnering opportunities which may ameliorate some procedural hurdles and offer opportunities to leverage the impacts of cases to wider effect.
Constructing and advancing clever legal arguments in respect of climate change is only one part of the challenge advocates face in bringing climate change cases before courts. Before a lawsuit sees its ‘day in court’ there
are numerous procedural questions that must be addressed including
• Is there a suitable claimant with standing to bring the claim?
• Are capable legal representatives (especially barristers) and other experts available and able to assist with the case, often on a pro bono basis?
• Is there a suitable court that will have jurisdiction to hear the contemplated claims?
• Is merits review (de novo review of law and facts) available or are claimants limited to bringing a judicial review claim (review of legal process
• Are there significant costs risks associated with bringing the litigation and if so are clients or funders willing or able to shoulder those costs?
The first generation of climate change cases in Australia has been heavily shaped by these considerations, which will be equally pertinent for next generation lawsuits. This has often led to a preference for cases that can be pursued through merits review under planning and environmental legislation before specialist environmental courts and tribunals that have open or relaxed standing rules and less stringent requirements around the allocation of litigation costs. These cases also tend to be those that are within the ‘wheelhouse’ of the EDOs (as the principal legal organisations involved in representing claimants) and for which there is a well-defined group of barristers and experts able to assist.
In considering a next generation of climate change litigation with the potential for more transformative impact, Australian environmental advocates need to be aware that some of the procedural hurdles that have been side-stepped or minimised in first generation cases may re-emerge as major barriers. One example is that of standing, which has posed minimal problems for climate change litigants taking merits or judicial review claims under Australian environmental legislation. For private law claims in torts or under corporations law, standing is likely to be a more significant hurdle given the need to demonstrate some special interest or loss to the plaintiffs to found a claim. The recent US judgment in Juliana illustrates some of the ways that a standing case can be made even in a situation of diffuse harms with broad-ranging effects. Nonetheless, with some of the next generation litigation avenues there is a greater risk of cases being struck out at a threshold stage than would be the situation for more traditional merits or judicial review cases under planning or environmental legislation.
Conversely, some of the other potential procedural barriers to climate change litigation may be less critical for next-generation cases than for first-generation lawsuits. In particular, finding willing claimants, litigation funders and barristers may be easier in the context of high-profile litigation brought under legal theories that extend beyond environmental law and which may offer the potential for recovery of damages. For example, in climate-related cases such as the ‘Dieselgate’ litigation in the United States and Australia over Volkswagen’s cheating of emissions testing of vehicles, or actions suing government and private actors over flooding damage from the Queensland Wivenhoe dam release, a new constellation of litigation actors are emerging including plaintiff law firms specialising in class action litigation and major litigation funders such as IMF Bentham. This broadening of actors involved in climate change litigation is related to the growing range of parties pursuing such litigation, the expanding nature of these claims (eg financial loss or damage claims) and the different range of motives and interests that are driving the litigation. Indeed, the involvement of third-party commercial litigation funders is explicitly on the basis that if litigation is successful, the funder will be entitled to a percentage of the awarded amount. A wider range of barristers than the usual advocates tapped into environmental cases have also expressed interest in novel cases such as an Urgenda-style action that might involve constitutional, tortious or administrative law claims.
If threshold procedural issues can be suitably resolved, challenges may still remain in adequately presenting and proving a climate change claim to the satisfaction of the deciding court. One of the issues that has posed a perpetual trial for climate change cases, particularly ‘mitigation’ lawsuits, is that of sufficiently proving causal links between a particular project (eg a coal mine) and broader climate change effects. This challenge has been less salient in an adaptation context where the focus is on the likelihood that climate change will affect adversely a particular project or development through, for instance, future sea level rise or increased risks of storms and coastal flooding. Evidentiary issues may manifest in the form of questions over the relevance of cumulative impacts from multiple projects similar to a particular project assessed, or deciding whether certain indirect climate change effects are ‘too speculative’ to be evaluated. They also may arise — as has happened in a number of Queensland coal mine cases, including the most recent Adani Carmichael coal mine litigation — through the defendant’s presentation of the insidious ‘substitution’ argument: that if this particular emissions-intensive project does not go ahead its environmental effects will simply be substituted by other such projects approved elsewhere, including in other parts of the world.
As Urgenda illustrated, there are ways of overcoming arguments of this kind where convincing evidence can be presented to courts that every emission of GHG contributes to climate change through accumulation of atmospheric GHG. For example, in Urgenda, the State of the Netherlands argued that the Dutch contribution to worldwide emissions was only 0.5% and that adopting a higher emissions reduction target would result in ‘a very minor, if not negligible, reduction of global greenhouse gas emissions’ and would have little influence on achieving the 2°C temperature goal without additional action by other countries with high emissions. The Court rejected this argument, finding that
[t]he fact that the amount of the Dutch emissions is small compared to other countries does not affect the obligation to take precautionary measures ... After all, it has been established that any anthropogenic greenhouse gas emission, no matter how minor, contributes to an increase of CO2 levels in the atmosphere and therefore to hazardous climate change.
The Court also noted that the Dutch per-capita emissions are among the
highest in the world and took into account that Annex 1 countries like the Netherlands, having taken the lead in taking mitigation measures under the UNFCCC, have ‘therefore committed to a more than proportionate contribution to reduction’.
Application of the precautionary principle offers another avenue for challenge in this regard, since where scientific uncertainty exists and serious or irreversible environmental threats can be identified, the general position under Australian environmental law is that the occurrence of such threats should be assumed and the burden of proof rests with the defendant to
Nonetheless, convincing courts of the legal merits of these arguments frequently rests on a strong supporting scientific case presented by credible, well-qualified experts. In this article there is not scope to address the many complexities and challenges that can arise in seeking to present scientific evidence in the courtroom in a way that judges will find persuasive. Suffice to say that first-generation cases have amassed considerable experience with different ways of approaching this challenge and generally have had better success in specialist environmental courts with flexible procedures for dealing with expert evidence.
For next-generation climate change cases, the evidentiary hurdles highlighted above are likely to be even more salient, particularly in those suits (based on public trust, torts and rights) where proof of the claim at issue relies on demonstrating causal links between legal breaches of rights or duties, and harm to particular plaintiffs or communities. It is also likely that such cases involving governmental or corporate defendants will be fiercely fought, with high levels of resources allocated to defending these claims, leading to lengthy, expensive legal battles.
As business perceptions shift to recognise both the range of risks posed to
companies by climate change (including physical, regulatory and market risks) and the associated business opportunities, new possibilities are emerging for advocacy organisations to partner in climate change litigation and related legal interventions with commercial players who have aligned interests in clean energy transition and adaptation. This can take a variety of forms, from public joint action (eg submitting regulatory complaints or lodging legal challenges) to behind-the-scenes facilitation of legal interventions (eg identifying causes of action, approaching potential litigants or providing legal advice and support). For environmental groups, this is potentially a way to facilitate innovative legal interventions using different areas of law that would otherwise have been difficult or impossible to access due to rules of standing. Partnering with commercial players may also mean that regulatory interventions, such as complaints to regulators, carry more weight and attain more visibility, heightening their impact. In addition, working together with a different range of partners potentially opens up new sources of funding and other resources to support litigation activities.
Next-generation climate change litigation strategies that take a partnering approach are emerging in other jurisdictions, particularly in the fields of competition law and company and investment law. By collaborating with clean technology companies seeking better market access and policy settings that support clean energy transition, and with investors with long-term risk horizons, advocacy groups are opening up new avenues for climate change litigation. Two recent examples from the United Kingdom are discussed briefly below to stimulate further discussion of the potential for growing this strategy in Australia and to invite consideration of the nature and extent of aligned interests, the strategic value of partnering, the various forms this might take, and the potential challenges that may arise.
European competition law, and particularly state aid rules, set limits and conditions on how European Union member states can subsidise certain sectors and industries. These rules are an important influence on the realisation of clean energy transition and climate change mitigation objectives to the extent that they support or constrain market access for renewable and other clean energy technologies. For this reason, state aid rules have become a focus for legal interventions by UK public interest environmental lawyers — ClientEarth — who view them as ‘a powerful tool to further the EU’s climate and energy goals, if they effectively support burgeoning industries like renewables’. However, direct legal interventions (eg alleging that subsidies to fossil fuel industries unfairly disadvantage clean energy and are unlawful) are largely restricted to commercial entities who are involved in the relevant market and who stand to be affected by any state aid payments, and therefore have legal standing to make a complaint. Strategic partnering and facilitation is one way for advocacy groups to overcome this barrier and access the available legal interventions.
In late 2014, ClientEarth was involved in supporting a legal challenge in the General Court of the European Union by a UK clean energy company, Tempus Energy, that stood to suffer from state aid payments associated with the UK government’s capacity mechanism. This case is an interesting example of strategic partnering and facilitation for a number of reasons. The strategic goals of ClientEarth and Tempus Energy relevantly align. Media statements made by ClientEarth surrounding the case clearly make this point:
If allowed to go ahead, the UK’s ‘capacity mechanism’ will artificially prop up the existing coal-reliant energy system by paying generators extra to produce more electricity at peak times. The costs will be passed on to consumers, regardless of when they use power. This is bad for the environment and for our pockets. We are supporting their action because it’s crucial to driving progress on climate change.
Further, ClientEarth, as an NGO, would not have standing to bring such an action. Unless it partners on some level with a commercial player it is limited to advocacy from the sidelines. If the General Court of the European Union finds in favour of Tempus Energy, the case will be of considerable significance in setting a precedent for ensuring market access and support for clean energy within the national capacity mechanisms that are currently being developed across Europe.
A detailed consideration of the potential for environmental groups to partner with renewable or other clean energy businesses in Australia to bring similar claims is beyond the scope of this article. The above example is included, not because it is directly transferable to an Australian context, but rather with the aim of inspiring investigation of the various litigation angles that could be pursued to hasten the development of market conditions supporting clean energy transition in Australia. The Australian National Electricity Market has been the subject of much recent public policy consideration including in relation to (perceived) tensions between greater uptake of renewables or clean energy technologies and energy security. While not exclusively focused on the enabling conditions for clean energy transition, ongoing public policy consideration is expected to shed some further light on aspects of market governance and market behaviour that may constrain energy transition and greater uptake of renewables. It may well be that litigation avenues to address some of the barriers faced by renewables and clean energy technologies, such as battery storage, emerge. Indeed, there has been some recent commentary exploring market concentration and market manipulation issues adversely affecting investment in renewable energy
As discussed in Part III, interest in using company and investment law avenues to advance action on climate change is growing in many jurisdictions. It has gained impetus with recent, high-profile investigations of the reporting practices of US fossil fuel companies, Peabody Coal and Exxon Mobil, and related litigation. The launch of the first shareholder class action of this nature against Exxon Mobil in November 2016 suggests that the commercial motivations for such legal intervention are increasing. As such, this approach may well escalate in a range of jurisdictions. There is, however, also potential for advocacy groups to engage in strategic partnering and facilitation in this area of law to help stimulate and facilitate further legal action by third parties. These parties might include groups of shareholders or pension (superannuation) fund members who have direct interests in enforcing legal obligations to disclose climate change risks and to take these into account in decision-making.
One of the most common areas where advocacy groups have engaged with corporations law on climate change to date is in supporting shareholders to bring resolutions to company annual general meetings seeking better disclosure of climate change risks and the adoption of more sustainable energy business strategies. The first climate change resolution was put to Exxon Mobil in 1997 and climate change proposals now represent a significant proportion of total proposals brought to US companies. Similar approaches are increasingly being implemented in other jurisdictions, including the United Kingdom and Australia. Public interest lawyers work with investor partners who have access to a wide range of investors and resources dedicated to lobbying and engagement in order to bring shareholder resolutions on
There are also examples of advocacy groups partnering with investors to put pressure on regulators to clarify and enforce the law around climate change risk disclosure. For example, a group of 16 investment managers signed a letter to the UK FRC in early 2016, together with ClientEarth. The letter detailed long-term investors’ view that fossil fuel-dependent companies should address climate-related risks in the newly introduced viability statements in their annual reports and sought a commitment that the FRC
engage with investors in developing any future regulatory guidance. Following this, two regulatory complaints were lodged against particular fossil fuel companies alleging inadequate climate risk disclosure and breach of directors’ duties, as described above. While these complaints were lodged by ClientEarth, investors were urged to support the complaints via a targeted investor briefing, and other organisations have highlighted the issue in public statements.
Another example of foundation-laying facilitative legal intervention by advocacy groups is the development of legal briefing papers targeted specifically at commercial players who may have an interest in identifying potential breaches and enforcing the law. Recent examples include an investor report prepared by ShareAction and ClientEarth on the extent of legal duties of pension funds to consider climate risks in their investments and the implementation gaps in practice, and the release of an opinion by a Senior Counsel on the scope of these legal duties.
The examples discussed above — both in competition law and corporations law — highlight some of the advantages for advocacy groups of partnering with commercial players and the various facilitating roles played by public interest lawyers in these contexts. Yet there are also challenges to pursuing these strategies in an Australian context. Stretched resources and limited expertise in these and other potentially relevant areas of commercial law are the greatest initial barriers for public interest lawyers. In this context, there is likely to be some reticence to allocating capacity to these new, untested and potentially risky approaches. There are also potential trade-offs to be negotiated in situations where the interests of NGOs and associated commercial players do not perfectly align — for example, around the level of control of strategy and the extent of publicity around partnerships and interventions. However, it seems that given the potential benefits of these partnering approaches, there will be increasing interest and experimentation with them in Australia also.
Developments around the world create important opportunities for an innovative next generation of Australian climate change litigation. New cases in the United States, the Netherlands, Pakistan and the Philippines help to put a human face on climate victims and provide models for how successful cases focused on rights, duties and common law principles might be framed. In addition, evolving efforts to use corporate and other commercial law mechanisms around the world, paired with growing attention in Australia to corporate disclosure of climate change risks, suggest interesting new possibilities for litigation. These emerging approaches create an opportunity for Australian advocates to explore new pathways while political change in the United States may simultaneously prompt innovation there.
As advocates here explore these new approaches, however, it will be critical for them to weigh the prospects of success against possibilities for negative opinions that could undermine further efforts. The more limited US experiments in public nuisance and human rights illustrates potential for courts to cut off novel pathways, and any next-generation climate change litigation in Australia will need to be framed in ways that minimise those risks. In addition, because existing approaches have achieved important successes and may represent the greatest likelihood for positive outcomes in the future, they should not be neglected as these new pathways are explored.
Election results in Australia and in the United States highlight the precarious nature of climate change policy, which is all the more worrying in a broader context in which current efforts are not nearly enough to prevent the worst impacts of climate change. Litigation remains an important tool to push and block government action, and to advance necessary mitigation and adaptation efforts. In that context, an innovative and effective next generation of Australian climate change litigation is critical.

Justice Stein in this article was discussing judicial innovation to develop understanding and application of the precautionary principle as a central principle of environmental law. Other members of the judiciary have argued that a similarly progressive approach is necessary in cases dealing with climate change. For instance, in the recent US decision of Juliana v United States of America, 217 F Supp 3d 1224, 1263 (D Or, 2016), discussed below, Aiken J of the US District Court of Oregon urged that ‘[e]ven when a case implicates hotly contested political issues, the judiciary must not shrink from its role as a coequal branch of government’.

 While first-generation climate change cases have been decided by both state and federal courts and tribunals across Australia, many of the cases with the most far-reaching impacts are decisions of the NSWLEC: see, eg, the ‘Anvil Hill’ case of Gray v Minister for Planning  NSWLEC 720; (2006) 152 LGERA 258. Courts in other jurisdictions, such as the South Australian Environment, Resources and Development Court, the Planning and Environment Court in Queensland and the Victorian Civil and Administrative Tribunal have also decided a

These discussions clearly recognise that international models will need to be adapted to local circumstances and take account of local legal constraints. These cases in other jurisdictions are thus considered an inspiration for new types of climate change cases in Australia rather than examples that can be directly transposed into the Australian legal environment.

 Climate change justice is a rather elastic term used in many different ways by different
groups in different contexts. The Climate Change Justice and Human Rights Task Force of
the International Bar Association provides a leading discussion of the concept: International
Bar Association, Climate Change Justice and Human Rights Task Force, Achieving
Justice and Human Rights in an Era of Climate Disruption (Report, 2014) 2 <www.ibanet.org/ PresidentialTaskForceClimateChangeJustice2014Report.aspx>, archived at <https://perma. cc/HPH3-CP64>. The Task Force defined climate justice in the following terms: ‘To ensure communities, individuals and governments have substantive legal and procedural rights relating to the enjoyment of a safe, clean, healthy and sustainable environment and the means to take or cause measures to be taken within their national legislative and judicial systems and, where necessary, at regional and international levels, to mitigate sources of climate change and provide for adaptation to its effects in a manner that respects human rights.’
 There is no one agreed definition of climate change litigation but in general commentators point to the need for a specific framing of arguments, motives or the judgment in climate change terms: see, eg, David L Markell and JB Ruhl, ‘An Empirical Survey of Climate Change Litigation in the United States’ (2010) 40 Environmental Law Reporter 10644, 10647; Chris Hilson, ‘Climate Change Litigation in the UK: An Explanatory Approach (or Bringing Grievance Back In)’ in Fabrizio Fracchia and Massimo Occhiena (eds), Climate Change: La Risposta del Diritto (Editoriale Scientifica, 2010) 421, 422.

 It is recognised that merits and judicial review are also means to hold governments accountable for their decision-making. In first-generation cases, however, such actions are designed to ensure that governments meet statutory requirements and act within the law.
In next-generation cases, the focus is on how government policy, action or inaction
contributes directly to climate change and ways of holding governments to account for

 Paris Agreement (n 22) art 2.1(a).
 Ibid art 4.1.
 The 1992 UNFCCC — the parent treaty to the Paris Agreement — provided no firm guidance in this regard, merely aiming to ‘prevent dangerous anthropogenic interference with the climate system’: United Nations Framework Convention on Climate Change, opened for signature 9 May 1992, 1771 UNTS 107 (entered into force 21 March 1994) art 2.
 See Malte Meinshausen et al, ‘Greenhouse-Gas Emission Targets for Limiting Global Warming to 2°C’ (2009) 458 Nature 1158; Sivan Kartha, ‘Implications for Australia of a 1.5°C Future’ (Working Paper No 2016-09, Stockholm Environment Institute, 2016). In its fifth Assessment Report, the Intergovernmental Panel on Climate Change (‘IPCC’) established that atmospheric concentrations of GHG must be stabilised at 450 parts per million in order to achieve the 2°C target and provided their first explicit statements about the available carbon budget for various temperature targets: IPCC, Climate Change 2014: Synthesis Report (Report, 2015) 20. For example, in Table 2.2 of the report, the IPCC provided global carbon budgets that corresponded to three temperature thresholds (1.5°C, 2°C, 3°C) and three probabilities of keeping global temperature increases below these thresholds (66%, 50%, 33%):
 Paris Agreement (n 22) art 14.1.
 Rules of evidence concerning judicial notice of matters of common knowledge are a relevant consideration here. Given the high visibility and wide reliance on both the 1.5°C and 2°C temperature goals as indications of ‘safe’ levels of climate change, it is increasingly likely that a judge would take judicial notice of these matters. Section 144 of the uniform Evidence Acts provides that proof is not required about matters not reasonably open to question which are common knowledge or capable of verification by reference to an authoritative document. Also potentially important is the law regarding the relationship of treaties and domestic law, particularly in situations where the treaty has been ratified by the Australian government, but there is not domestic legislation giving express effect to its substantive goals and objectives, as is the case in relation to the Paris Agreement (including the 2°C temperature goal). For a broad consideration of the extent to which unincorporated treaties and international law more generally can affect the domestic law of Australia, through the interpretation of statutes, development of the common law and potentially broadening the scope of judicial review, see Glen Cranwell, ‘Treaties and Australian Law: Administrative Discretions, Statutes and the Common Law’  QUTLawJJl 5; (2001) 1 Queensland University of Technology Law and Justice Journal 49; Glen Cranwell, ‘Treaties and the Interpretation of Statutes: Two Recent Examples in the Migration Context’  AIAdminLawF 24; (2003) 39 AIAL Forum 49.
 Urgenda provides a good example of a court relying, in part, on international climate change science and treaty law to find that the Dutch government owed a duty of care to Urgenda to set and implement emissions reduction targets in line with these standards: Urgenda (n 18). Arguably, this line of reasoning would be strengthened following the successful conclusion and coming into force of the Paris Agreement with its clear temperature goal. In Urgenda, the Court relied on IPCC climate science, international climate change agreements under the UNFCCC and decisions and statements by European institutions and the Dutch government to find that the 2°C temperature goal was the widely accepted starting point for the development of climate policies and that substantial cuts in GHG emissions globally were required to meet this goal and thereby avert dangerous climate change: see especially Urgenda (n 18) [4.11]–[4.34]. The Court also considered the emissions reductions required to achieve this goal at a national scale, finding that the Netherlands would need to achieve a 25–40% reduction in emissions (based on 1990 levels) by 2020 in order to contribute proportionally to meeting this goal. The Court relied on this evidence to determine the substantive content of the duty of care that was found to be owed by the Dutch Government to Urgenda, with an ultimate finding that the state had a legal obligation to Urgenda to deliver at least a 25% reduction in GHG emissions (based on 1990 levels) by 2020: at [5.1].

 See generally n 67. Urgenda provides a relevant example of a court drawing on international climate science and treaty law to make a finding on the issue of transition timeframes and pathways. Using this evidence, the court found it was not adequate for the Dutch government to postpone substantial emissions reduction measures beyond 2020: Cox (n 68) 6–9. Article 4.1 of the Paris Agreement, which provides for transition to net zero emissions in the second half of the century would arguably strengthen such a line of reasoning and encourage a court to consider evidence of the emissions reduction pathways required to achieve

The Memorandum of Opinion outlines the applicable provisions within the Corporations Act 2001 (Cth) and relevant case law in relation to disclosure of business risks and director’s duties to exercise their powers and discharge their duties with the degree of care and diligence that a reasonable person in their circumstances would exercise. It confirms that, where they are reasonably judged to be foreseeable and material, the business risks posed by climate change (both physical and non-physical) should be disclosed under existing general risk disclosure requirements. Further, directors (and other officers) should carefully consider climate risks in the exercise of their legal duties. The opinion concludes that ‘[i]t is likely to be only a matter of time before we see litigation against a director who has failed to perceive, disclose or take steps in relation to a foreseeable climate-related risk that can be demonstrated to have caused harm to a company’: at 2 .

 Our focus here is on domestic law pathways, although environmental groups might also consider potential international law pathways (including transboundary harm) or accountability mechanisms. For a discussion of international law relevant to climate change, see Rosemary Rayfuse and Shirley V Scott (eds), International Law in the Era of Climate Change (Edward Elgar, 2012).

 There is increasing interest in this avenue for climate change litigation globally. For a discussion of the intersections between climate change and human rights, see Knox (n 39). On specific litigation efforts, see Jacqueline Peel and Hari M Osofsky, ‘A Rights Turn in Climate Change Litigation?’ (2018) 7 Transnational Environmental Law (forthcoming). In the Australian context, however, the possibilities for human rights claims are limited given the lack of a national bill of rights: ‘How Are Human Rights Protected in Australian Law?’, Australian Human Rights Commission (Web Page, 2006) <www.humanrights.gov.au/how-are-human-rights-protected-australian-law>, archived at <https://perma.cc/8J4M-VDJP>. Rights-based claims would need to rely on other avenues such as: international avenues of complaint (eg a complaint to the United Nations Human Rights Committee under the Optional Protocol to the International Covenant on Civil and Political Rights, opened for signature 19 December 1966, 999 UNTS 171 (entered into force 23 March 1976) (‘ICCPR’) on the basis that Australia’s domestic action is inadequate to safeguard rights in accordance with international obligations; judicial review of federal administrative decision-making on the basis that international human rights obligations must be taken into account; or actions at the state level, raising arguments under human rights charters in the Australian Capital Territory and Victoria. For a consideration of the viability of a complaint under the ICCPR, contending that Australia’s ongoing failure to adopt sufficient measures to reduce GHG emissions constitutes a violation of the rights of Torres Strait Islanders, see Owen Cordes-Holland, ‘The Sinking of the Strait: The Implications of Climate Change for Torres Strait Islanders’ Human Rights Protected by the ICCPR’  MelbJlIntLaw 16; (2008) 9 Melbourne Journal of International Law 405.
 The United States has seen a wave of lawsuits in the last few years based on arguments that government failures to adequately constrain GHG emissions breach a public trust obligation to safeguard natural resources in the public interest. For a discussion of the atmospheric public trust law suits, see Mary Christina Wood, ‘Atmospheric Trust Litigation Across the World’ in Ken Coghill, Charles Sampford and Tim Smith (eds), Fiduciary Duty and the Atmospheric Trust (Ashgate, 2012) 99. The most recent of these US cases is Juliana (n 1) in which Aiken J of the US District Court for District of Oregon issued an opinion and order denying the US government and fossil fuel industry’s motions to dismiss a constitutional climate change lawsuit filed by 21 youths on 10 November 2016. This preliminary decision confirmed that the plaintiffs have a justiciable case and standing to pursue their case at trial. The plaintiffs argued that the defendants’ actions in not adequately mitigating climate change violate their substantive due process rights to life, liberty, and property, as safeguarded in the United States Constitution and that the defendants violated their obligation to hold certain natural resources in trust for the people and for future generations. They sought a declaration that their constitutional and public trust rights had been violated and an order enjoining the defendants from violating those rights and directing them to develop a plan to reduce carbon dioxide emissions: see at 1233–4. The case is ongoing. For a recent review of the potential impact of this case, see Michael C Blumm and Mary Christine Wood, ‘No Ordinary Lawsuit: Climate Change, Due Process, and the Public Trust Doctrine’ (2017) 67 American University Law Review 1.
 To date, there has been only limited consideration of the potential applicability of the public trust doctrine to an Australian environmental litigation and policy context and limited opportunity for Australian judges to consider its applicability: see, eg, Tim Bonyhady, ‘A Usable Past: The Public Trust in Australia’ (1995) 12 Environmental and Planning Law Journal 329; Jessica Simpson, ‘The Public Trust Doctrine and Its Relevance in Australia’ (Conference Paper, Environmental Defender’s Office New South Wales Coastal Solutions Forum, 15 November 2003); Bruce Thom, ‘Climate Change, Coastal Hazards and the Public Trust Doctrine’ (2012) 8(2) Macquarie Journal of International and Comparative Environmental Law 21.
 This question has also prompted academic consideration: see, eg, Baxter, ‘Urgenda-Style Climate Litigation Has Promise in Australia’ (n 44). Baxter seeks to unpack the legal hurdles that might prevent the Commonwealth being found liable in negligence for their insufficient efforts to mitigate climate change.
 Urgenda (n 18) [3.2], [4.26].
 The Constitution of the Kingdom of the Netherlands 2008 art 21 [Ministry of the Interior and Kingdom Relations, Constitutional Affairs and Legislation Division in collaboration with
the Translation Department of the Ministry of Foreign Affairs trans, The Constitution of the Kingdom of the Netherlands 2008 (2008) <www.government.nl/documents/regulations/
2012/10/18/the-constitution-of-the-kingdom-of-the-netherlands-2008>, archived at <https://
perma.cc/AV5T-4UUK>]. Article 21 provides that ‘[i]t shall be the concern of the authorities to keep the country habitable and to protect and improve the environment’. Urgenda argued that the Netherlands, by adopting a GHG reduction target below the 25–40% range, was not fulfilling its constitutional duty under art 21: Urgenda (n 18) [3.2], [4.36]–[4.44].
 Urgenda advanced arguments that by failing to adopt adequate emissions reduction targets, the State was infringing or acting contrary to art 2 (the right to life) and art 8 (respect for private and family life) of the Convention for the Protection of Human Rights and Fundamental Freedoms, opened for signature 4 November 1950, 213 UNTS 221 (entered into force 3 September 1953): Urgenda (n 18) [3.2], [4.45]–[4.50].
 Urgenda relied on a large body of international and EU climate law, including the UNFCCC and the Kyoto Protocol, EU Directives on climate change, and the Treaty on the Functioning of the European Union, opened for signature 7 February 1992,  OJ C 115/199 (entered into force 1 November 1993) in its arguments that the State was causing damage to others by its failure to adopt an adequate mitigation policy, despite its international legal obligations, and that the State was acting unlawfully towards Urgenda by failing to fulfil its international legal obligations: Urgenda (n 18) [4.35]–[4.44]. The Court concluded that ‘a legal obligation of the State towards Urgenda cannot be derived’ from the above rules and instruments: at [4.52]. However, these rules and instruments were found to be relevant in determining both the degree of discretionary power that the State is entitled to in exercising its functions and the minimum degree of care that the State is expected to observe: at [4.35]–[4.52].

This analysis is referenced in the law applicable to NSW and refers particularly to the Civil Liability Act 2002 (NSW), but as the authors note, the common law of torts is uniform throughout Australia, and the statutory regimes in various states and territories are in many respects directly comparable: at 86 [5.50] n 82.
 Ibid 88 [5.55]. Relevant case law suggests an extreme reluctance on the part of courts to attribute a duty of care where there are a multitude of diverse agents who have contributed to the harm and where it would be disproportionately burdensome to impose liability on any one particular defendant: at 88 [5.56].

The authors do acknowledge potentially applicable lines of precedent in the case law (including in the dust diseases context) to overcome the limitations of the ‘but for’ test of causation in this context and note that ‘[t]he question of causation would ... revolve around whether making some definite contribution to a process resulting from the cumulative effect of a multitude of such contributions (as well as extrinsic causes) could or should be regarded as a legal cause’: at 97 [5.73]. The applicable statutory test of causation (such as that contained in s 5D of the Civil Liability Act 2002 (NSW)) would be relevant here.
 Ibid 97–8 [5.75]–[5.76]. The authors note this would be a likely result in situations where the defendant’s negligent actions were only a minor contribution to the damage, where the damage is distant in space and time from the actions of the defendant or in light of broader policy considerations, such as the broader consequences of imposing liability on a particular defendant in these complex circumstances.

In this decision, it was determinative that the plaintiff was able to prove that the defendant intended to breach his duty of care and there was near absolute certainty that doing so would harm the plaintiff in a way that could not possibly be remedied by an ex post claim in damages: at 113–14 , 137–8 –; Baxter, ‘Urgenda-Style Climate Litigation Has Promise in Australia’ (n 44) 71.

 Ibid 72–3. Baxter’s argument is based on a claim brought against a governmental defendant by a plaintiff who stands to be affected by direct climate change impacts for which there is strong scientific evidence demonstrating the link between GHG emissions and the impact. On his analysis of the case law, he presents a number of arguments that would support a finding of a duty of care, including the foreseeability of harm, the degree of control the defendant can exercise, the plaintiff’s vulnerability, any assumption of responsibility by the defendant, and the nature and degree of hazard likely to occur. For example, in relation to the issue of control, he notes that the Australian Government exerts considerable control over the nation’s emissions via multiple legislative and executive functions including: controlling the National Electricity Market which is responsible for the largest share of Australia’s emissions; project assessment and approval processes under Environment Protection and Biodiversity Conservation Act 1999 (Cth) (‘EPBC Act’) which apply to emissions intensive projects such as coal mines and power stations; market mechanisms such as the Emissions Reduction Fund which forms the centrepiece of the Australian Government’s climate change policy; and controlling transport emissions via vehicle emissions standards.

Gleeson CJ discusses justiciability in the context of a negligence claim against a governmental authority: ‘Courts have long recognised the inappropriateness of judicial resolution of complaints about the reasonableness of governmental conduct where such complaints are political in nature ... In the case of a governmental authority, it may be a very large step from foreseeability of harm to the imposition of a legal duty, breach of which sounds in damages, to take steps to prevent the occurrence of harm. And there may also be a large step from the existence of power to take action to the recognition of a duty to exercise the power.’

 For example, Australia, the United Kingdom and the United States all require publicly listed companies to make regular disclosures of their financial position and any material business risks facing the company. The relevant provisions are discussed in Anita Foerster et al, ‘Keeping Good Company in the Transition to a Low Carbon Economy? An Evaluation of Climate Risk Disclosure Practices in Australia’ (2017) 35 Company and Securities Law Journal 154, 163–4, 175 n 111, 177 n 124. Where the regimes differ is in relation to the prescriptions requiring disclosure of the particular risks posed by climate change. For example, in the United States, the Securities and Exchange Commission (‘SEC’) issued specific guidance in 2010 on how the existing disclosure requirements under federal securities laws applied to climate change matters: Commission Guidance regarding Disclosure Related to Climate Change, 75 Fed Reg 6290 (8 February 2010). In the United Kingdom, while the disclosure requirements are broadly similar to Australia, listed companies are also explicitly required to report on GHG emissions in their annual reports: Companies Act 2006 (Strategic Report and Directors’ Report) Regulations 2013 (UK) SI 2013/1970, pt 7.

 The New York Attorney General investigated the SEC filings from Peabody Energy Corporation and found that these disclosures misled shareholders by understating the severe potential impacts of carbon risk to its business and claiming an inability to predict the financial impacts of future climate policy laws or regulations. This investigation, under state laws prohibiting false or misleading conduct in connection with securities transactions, was settled in November 2015 and Peabody, without admitting to fraudulent disclosure practices, undertook to improve climate risk disclosure: see New York State Office of the Attorney General (n 85); Attorney General of the State of New York Environmental and Investor Protection Bureaus, ‘Assurance of Discontinuance’, In the Matter of Investigation by Eric T Schneiderman, Attorney General of the State of New York, of Peabody Energy Corporation (Assurance No 15-242, 8 November 2015) <https://ag.ny.gov/pdfs/Peabody-Energy-Assurance-signed.pdf>, archived at <https://perma.cc/QD5K-FTVP>.

 For the latest decision in this litigation, see Australian Conservation Foundation Inc v Minister for the Environment and Energy  FCAFC 134. This is the most recent in a series of lawsuits through which the Australian Conservation Foundation (‘ACF’) has challenged the federal government’s approval under the EPBC Act of the Adani Carmichael coal mine in the Galilee basin that will be the largest such mine in the Southern hemisphere. In Australian Conservation Foundation Inc v Minister for the Environment  FCA 1042, , the Federal Court dismissed the legal challenge to the EPBC Act approval of the mine and accepted that the Minister concluded that the combustion emissions from the proposed mine would have no relevant impact on the Great Barrier Reef. On 25 August 2017, the Full Federal Court in Australian Conservation Foundation Inc v Minister for the Environment and Energy  FCAFC 134 then dismissed an appeal lodged in September 2016 by the ACF challenging the lawfulness of the Minister’s finding that the burning of coal from the Carmichael mine will not have an impact on global warming and the Great Barrier Reef.
 This terminology is consistent with language used in the Greenhouse Gas Protocol, the most widely used protocol internationally in accounting for greenhouse gas emissions: ‘Companies and Organizations’, Greenhouse Gas Protocol (Web Page) <www.ghgprotocol.org/companies-and-organizations>, archived at <https://perma.cc/ZDX7-68XY>. Scope 1 emissions are direct emissions from an activity; scope 2 emissions are indirect emissions from generation of purchased energy; and scope 3 emissions are all other indirect emissions occurring in the reporting entity’s value chain: The Greenhouse Gas Protocol: A Corporate Accounting and Reporting Standard (World Business Council for Sustainable Development and World Resources Institute, rev ed, 2004) 25. The main source of scope 3 emissions in coal mining comes from burning harvested coal: Peel and Osofsky (n 8) 88–9 n 143. It was accepted that that 98% of the Adani Carmichael coal mine’s GHG emissions would be scope 3 emissions; however, the Court did not accept that such emissions were relevant to consider in assessing the degree of likely environmental impact from the mine on the nearby Great Barrier Reef: see Australian Conservation Foundation Inc v Minister for the Environment  FCA 1042, –, –.

 In many cases, environmental legislation includes open or relaxed standing requirements. Even in the case of the federal EPBC Act, the definition of a ‘person aggrieved’ for the purposes of judicial review is expanded to include individuals and organisations with a record of involvement with environmental issues: EPBC Act (n 122) s 487.

 Juliana (n 1) 1242–8. Aiken J applied a multi-part test to determine if the plaintiffs had standing to bring the case. For the first limb of the test, the plaintiffs were required to demonstrate ‘concrete and particularized, not abstract or indefinite’ harms to their interests (personal, economic and aesthetic) and that these harms were actual and imminent: at 1244. In this case, the plaintiffs led evidence of the types of climate change impacts affecting their interests (eg lead plaintiff Kelsey Juliana alleged algae blooms harmed the water she drinks, and low water levels caused by drought killed the wild salmon she eats): at 1242. The plaintiffs also established that harms caused by climate change are ongoing and likely to continue in the future. Aiken J found that this limb of the test would be satisfied: at 1244. For the second limb of the test, plaintiffs were required to establish a line of causation between the actions of the defendant and the harms suffered by the plaintiffs that was ‘more than attenuated’: at 1244. Aiken J noted that it was inappropriate to make a finding on this limb of the test without the benefit of further evidence being led. She therefore deferred the issue to the next stage of the proceedings, but did comment on the extent of GHG emissions at issue in these proceedings (emissions controlled by the federal US government which allegedly amount to 25% of global emissions) and the advances in climate science which would support the plaintiff’s case: at 1245–6. The final limb of the test requires the plaintiffs to establish redressability — a substantial likelihood that the requested remedy would redress the injury: at 1246–7. The plaintiffs sought a court order that the defendants prepare and implement an enforceable national remedial plan to phase out fossil fuel emissions and draw down excess atmospheric carbon. Aiken J noted that ‘[i]f plaintiffs can show, as they have alleged, that defendants have control over a quarter of the planet’s greenhouse gas emissions, and that a reduction in those emissions would reduce atmospheric CO2 and slow climate change, then plaintiffs’ requested relief would redress their injuries’: at 1247.

 For a discussion of business risks and opportunities associated with climate change, see Task Force on Climate-Related Financial Disclosures, Phase I Report of the Task Force on Climate-Related Financial Disclosures (Report, 31 March 2016) 24. Climate changes risks are often categorised as physical and non-physical. Physical risks, associated with both acute weather events and longer term changes to rainfall, temperature and other factors, include potential disruptions to operations, transportation, supply chains; damage to physical assets; and reduced resource availability. Non-physical risks refer to a range of interacting legal, technological, market and reputational risks. For example, new laws and policies introduced to address climate change are likely to impose compliance costs and liabilities and lead to restrictions on the use of carbon-intensive assets. On the flipside of this multitude of risks is the range of potential commercial opportunities associated with transition to a low
carbon economy, including the development of new clean energy markets and improved operating efficiencies.
 Treaty on the Functioning of the European Union (n 99) arts 107–9 provide the genesis for state aid rules. Article 107 prohibits ‘any aid granted by a Member State or through State resources in any form whatsoever which distorts or threatens to distort competition by favouring certain undertakings or the production of certain goods ... in so far as it affects trade between Member States’, and then provides for a series of exceptions to this prohibition, including ‘aid to facilitate the development of certain economic activities or of certain economic areas, where such aid does not adversely affect trading conditions to an extent contrary to the common interest’. Article 108 grants power to the European Commission to adjudicate over state aid, including approving state aid proposals and initiating a procedure in the European Court of Justice to rule on the compatibility of state aid with the internal market. The European Commission has produced guidelines setting out conditions under which aid for energy and environmental protection policy objectives (eg to support clean energy transition and climate change mitigation goals) may be considered compatible with the internal market: Guidelines on State Aid for Environmental Protection and Energy 2014–2020,  OJ C 200/1. The recent decision of the General Court of the European Union regarding Germany’s renewable energy law illustrates how state aid for clean energy transition goals (in this case, feed-in tariffs and market premiums, which guarantee producers of renewable energy a higher price for the electricity they produce than the market price) may be found to be compatible with the internal market: Federal Republic of Germany v European Commission (General Court, T-47/15, 10 May 2016).

 See, eg, Dylan McConnell and Mike Sandiford, Winds of Change: An Analysis of Recent Changes in the South Australian Electricity Market (Report, Melbourne Energy Institute, August 2016) 30–7, which notes concerns about market concentration and the improper exercise of market power which favours incumbent integrated energy companies and disadvantages smaller renewables or clean technology companies. See also Bruce Mountain, ‘Market Power and Generation from Renewables: The Case of Wind in the South Australian Electricity Market’ (Working Paper No 51, Centre for Strategic Economic Studies, January 2013) 21–2, which argues similarly that the exercise of market power in South Australia results in a bias against investment in wind farms.

 For example, the Australasian Centre for Corporate Responsibility (‘ACCR’) lodged a number of special shareholder resolutions with the big banks in the 2015 annual general meeting (‘AGM’) season, seeking amendments to the various company constitutions such that ‘each year at about the time of the release of the Annual Report, at reasonable cost and omitting any proprietary information, the Directors report to shareholders their assessment of the quantum of greenhouse gas emissions [the company is] responsible for financing calculated, for example, in accordance with Greenhouse Gas (GHG) Protocol guidance’: ‘Big Banks’, Australasian Centre for Corporate Responsibility (Web Page) <www.accr.org.au/big_banks>, archived at <https://perma.cc/ZM9J-89T8>.

 In 2015 and 2016, ClientEarth partnered with the Aiming for A coalition of investors to bring special resolutions to the AGMs of large fossil fuel companies, including Shell, BP, Rio Tinto, Glencore and Anglo American. If 75% of the meeting support these special resolutions, they become binding on the board. Resolutions at BP and Shell in 2015 passed with more than 98% approval: ‘Mining Giant Anglo American Backs Climate Change Resolutions’, ClientEarth (Web Page, 14 March 2016) <www.clientearth.org/mining-giant-anglo-american-backs-climate-change-resolutions>, archived at <https://perma.cc/J9MG-DJWD>.

 A focus on human ‘victims’ of climate change arguably offers a more compelling narrative
for climate change litigation by making ‘climate change more tangible and more immediate’: David B Hunter, ‘The Implications of Climate Change Litigation: Litigation for International Environmental Law-Making’ in William CG Burns and Hari M Osofsky (eds), Adjudicating Climate Change: State, National, and International Approaches (Cambridge University Press, 2009) 357, 360.
 A recent case relying in part on a constitutional rights claim in a climate change context is South Africa’s first climate change decision. The North Gauteng High Court ruled in favour of environmental justice organisation, Earthlife Africa Johannesburg, and referred an appeal against the environmental authorisation for a new coal-fired power station back to the Minister of Environmental Affairs on the basis that its climate change impacts had not properly been considered: Earthlife Africa Johannesburg v Minister of Environmental Affairs  ZAGPPHC 58;  2 All SA 519 (GP) (8 March 2017).
 See United Nations Framework Convention on Climate Change Secretariat, Synthesis Report on the Aggregate Effect of the Intended Nationally Determined Contributions, UN Doc FCCC/CP/2015/7 (30 October 2015) 11. This report assesses countries’ current NDCs and concludes that they are not sufficient to limit the estimated temperature rise to below the ‘safe’ level of 2°C.
