In accordance with Article 15 of the Aarhus Convention, the first meeting of the parties to this Convention established a non-judicial and consultative Compliance Committee to consider, among other matters, individual cases concerning compliance by parties with their obligations. The Committee is traditionally viewed as a non-judicial, soft mechanism and its rulings as non-binding, soft law. In recent years, however, to support the claim that rulings of the Committee have an impact and legal effects, some scholars have departed from the traditional perspective and characterized the Committee as a more judicialized mechanism, which issues legally binding rulings.

This characterization assumes a correlation between judicialization and binding effect on the one hand, and legal effect on the other. The latter claim, however, has not been supported by a systematic assessment of the impact of the Committee's rulings on domestic practice. Against this background, the article assesses the impact of Article 9-related rulings of the Committee, issued between 2004 and 2012, on national legal orders. The assessment reveals that in fewer than 41% of the cases parties recorded some degree of compliance with the rulings of the Committee, whereas in 59% they recorded no progress. The quantitative assessment and respective qualitative insights, among other factors, suggest that the normative character of the Committee and its rulings play an auxiliary role in the process of ensuring compliance with the provisions of the Aarhus Convention. The decision of parties to comply is determined typically by the substance of the rulings as they stand in relation to domestic circumstances rather than by the institutional features of the Committee and binding effect of its rulings.

At the end of the 2015 Academy Award-winning film The Big Short, which explores the origins of the 2008 Global Financial Crisis, a caption notes that the Wall Street investor protagonist of the film who predicted the collapse of the United States (US) housing market would now be ‘focused on one commodity: water’. Water is sometimes described in popular culture as ‘the new oil’ or ‘more valuable than gold’. It is predicted to be the subject of increasing uncertainty, competition, conflict, and even war, as increasing demand from a growing human population and development meets reduced supply as a result of poor management, overuse, and climate change.

Domestic climate change litigation is prospering across the globe to the extent of becoming a transnational phenomenon of growing importance. At the international level the Paris Agreement, although still in its infancy, has been established as the core element of the climate change governance framework. This article explores the still opaque relationship between domestic climate change litigation and the Paris Agreement. It is argued that dynamic interaction between domestic litigation and the Paris Agreement may improve the overall efficacy of both regimes. On the one hand, an examination of the Paris Agreement's architecture and provisions reveals pathways that are already being used or can be explored further in litigation. On the other hand, litigation can assist and complement the Paris Agreement with regard to its implementation and progress towards its overall goals. The result may deliver more than a multi-level perspective on climate change law. As it captures the law in action on different levels, the proposed ‘cross-level’ approach has due regard to the implications of the mutual supportiveness or complementarity of legal tools. It also thereby responds to the concern of whether the law can be of significant benefit in addressing complex global issues like climate change.

There is a critical research gap regarding the trade and animal welfare interface: we do not know, empirically, what the impact of trade on animal welfare is. This gap exists, in part, as a result of the paternalism of international trade law and the underdevelopment of global animal law. This article addresses, firstly, the collision of dichotomous trade and animal welfare priorities in legal and political systems. It then explores attempts at reconciliation by the World Trade Organization and the European Union. This involves an investigation of the impact of trade on animal welfare. This impact is categorized into four component parts: (i) open markets, (ii) low animal-welfare havens, (iii) a chilling effect, and (iv) lack of labelling. Case studies from the European Union are examined. Thirdly, the article critiques trade law and policy as ill-suited primary drivers of global governance for animals. Global animal law is identified as a promising alternative, although its early development has been unduly affected by international trade law.

The rapid emergence of rights of Nature over the past decade across multiple contexts has fostered increasing awareness, recognition, and, ultimately, acceptance of rights of Nature by the global community. Yet, too often, both scholarly publications and news articles bury the lede – namely, that the most transformative cases of rights of Nature have been consistently influenced and often actually led by Indigenous peoples. In this article we explore the ontologies of rights of Nature and earth jurisprudence, and the intersections of these movements with the leadership of Indigenous peoples in claiming and giving effect to their own rights (while acknowledging that not all Indigenous peoples support rights of Nature). Based on early observations, we discern an emerging trend of increased efficacy, longevity, and transformative potential being linked to a strongly pluralist approach of lawmaking and environmental management. A truly transformative and pluralist ecological jurisprudence can be achieved only by enabling, and empowering, Indigenous leadership.

This article draws on empirical research conducted with European Commission officials in three Directorates-General and its other services on their perception of how the legislative and policy-making process facilitates the interaction of science and environmental law. This article deploys Sheila Jasanoff's theoretical framework of co-production as an important lens to examine how the European Commission creates this interaction of science and law in environmental policy making and identifies how the Commission incorporates different voices and stakeholders in this policy area. The Commission can be seen as a vehicle of co-production of science and law in EU environmental policy by building strong expert identities, putting in place institutional processes and instruments, and creating discourse between scientists and lawyers leading to outputs of co-production. It is argued that in actively facilitating co-production, the Commission underpins the legislative and policy-making process with its institutional values.

This article investigates the relationship between legal personality for nature and Indigenous philosophies by comparing two cases: the Ecuadorian Constitution of 2008 and the 2014 Te Urewera Act of Aotearoa, New Zealand. Through these case studies the article considers the nature of Indigenous relations with the concept of rights of nature, arguing that this relation is primarily strategic, not genealogical. The article engages with the concept of legal personality and shows that it is not a direct translation of Indigenous conceptions, but rather a potential straitjacket for Indigenous emancipatory politics. The radical character of Indigenous ontologies is not fully reflected in the concept of legal personality. Furthermore, the way in which rights are granted to the natural environment is an important part of the effect that such rights might have on Indigenous communities. Despite some affinities between rights of the environment and Indigenous philosophies, overstating the connection might constrain the radical political and legal implications of Indigenous thought.

Domestic courts enjoy generous attention in international political and legal climate change literature. As a result of the reluctance of national governments to pursue climate protection measures, courts are called on to enforce international climate goals. This article assesses two domestic climate change cases (the Thabametsi Case and the Vienna Airport Case) in the light of Anthea Roberts’ functional understanding of the role of domestic courts in international law. It argues that domestic courts play a pivotal role in linking international obligations of conduct with national obligations of result. This role depends on domestic contexts and, therefore, requires a comparative approach.

Legislation emerging from Treaty of Waitangi settlements provide Māori, the Indigenous people of Aotearoa New Zealand, with new opportunities to destabilize and decolonize the colonial knowledge, processes and practices that contribute towards negative material and metaphysical impacts on their rohe [traditional lands and waters]. In this article we focus our attention on the Nga Wai o Maniapoto (Waipa River) Act 2012 and the Deed of Settlement signed between the Crown (the New Zealand government) and Ngāti Maniapoto (the tribal group with ancestral authority over the Waipā River) as an example of how the law in Aotearoa New Zealand is increasingly stretched beyond settler-colonial confines to embrace legal and ontological pluralism. We illustrate how this Act serves as the foundation upon which Ngāti Maniapoto are seeking to restore, manage, and enhance the health of their river. Such legislation, we argue, provides a far higher degree of recognition of Māori rights and interests both as an outcome of the settlement process and by strengthening provisions under the Resource Management Act 1991 regarding the role of Māori in resource management. We conclude by suggesting that co-governance and co-management arrangements hold great potential for transforming river management by recognizing and accommodating ontological and epistemological pluralism, which moves Aotearoa New Zealand closer to achieving sustainable and just river futures for all.

What scholars referred to as a climate change litigation ‘explosion’ in 2015 has today become an established movement which is unlikely to stop in the near future: worldwide, over a thousand lawsuits have been launched regarding responsibility for the dangers of climate change. Since the beginning of this trend in transnational climate litigation scholars have warned that the separation of powers is threatened where judges interfere with the politically hot issue of climate change. This article uses Jürgen Habermas's political theory on deliberative democracy to reconstruct the tension between law and politics generated by these lawsuits. This reconstruction affords a better understanding of the implications of climate change litigation: while the role of the judiciary as such remains unchanged, the trend is likely to influence the democratic legitimacy of judicial lawmaking on climate change, as it indicates an increasing realization that a sound environment is a constitutional value and is therefore a prerequisite for democracy.

The role of calculative practices such as goals and indicators in international environmental governance causes concern among many observers, who view them as promoting a reductivist approach to the non-human world and privileging economic understandings of environmental governance above all others. Yet they possess enormous potential to provide insights into the non-human world that could be of great benefit to governance. This article takes seriously critical perspectives of calculative practices, while exploring a weakness in much of the critical literature, namely a failure to examine assumptions about the nature of scientific knowledge and the manner in which it is, and ought to be, taken up by policy makers. I contend that both the design of environmental regimes and critical analyses of these regimes bear the marks of the influence, albeit indirect, of early 20th century views on the superiority of scientific knowledge and its unique capacity to ground decision making. I argue that a richer, more nuanced account of the co-production of ecological metrics such as goals and indicators and their potential contributions to ecosystem governance and sustainability is necessary. With such accounts, scholars and political authorities would be in a better position to address the very real pitfalls and dangers of calculative practices while not feeling compelled to forego these potentially powerful approaches.

On 10 April 2019 the Supreme Court of the United Kingdom delivered judgment in the case of Vedanta v. Lungowe, which concerned the liability of an English company for environmental damage caused by its subsidiary in Zambia. The decision confirms that English parent companies can owe a duty of care to foreign claimants affected by operations of their subsidiaries abroad and that the English courts may have jurisdiction to hear such cases, even when a foreign court is a more appropriate place for the trial. It establishes an important precedent for providing access to justice for foreign claimants in transnational corporate liability litigation. Given the global presence of English companies and the fact that their foreign subsidiaries have been involved in multiple cases of environmental damage in the host states, the decision could give an impetus to future claims being brought in the English courts. Also, the decision opens some interesting possibilities for climate change liability litigation against English parent companies and their foreign subsidiaries, as their cumulative greenhouse gas emissions are likely to be considerably higher than when taken separately, arguably making prospective claims against them more viable.

Cases involving climate change have been litigated in the courts for some time, but new directions and trends have started to emerge. While the majority of climate litigation has occurred in the United States and other developed countries, cases in the Global South are growing both in terms of quantity and in the quality of their strategies and regulatory outcomes. However, so far climate litigation in the Global South has received scant attention from the literature. We argue that climate litigation in the Global South opens up avenues for progress in addressing climate change in highly vulnerable countries. We first highlight some of the capacity constraints experienced in Global South countries to provide context for the emerging trend of strategic climate litigation in the area. In spite of significant constraints experienced, the strategies adopted by litigants push the climate litigation agenda forward as a result of their outward-looking objective of combating ongoing environmental degradation, and, on a doctrinal level, the way in which they link climate change and human rights. Bearing in mind the limitations resulting from the selective nature of the cases examined, we draw upon Legal Opportunity Structures (LOS) approaches and identify two reasons for innovative cases and outcomes in Global South strategic climate litigation: (i) how litigants are either overcoming or using procedural requirements for access to environmental justice, and (ii) the existence of progressive legislative and judicial approaches to climate change. The strategies and outcomes from these judicial approaches in the Global South might be able to contribute to the further development of transnational climate change litigation.

A widespread response to the pressures placed on the ecological condition of rivers is the design and implementation of environmental flow regimes in domestic regulatory frameworks for water. Environmental interests in water are not confined to hydrological functioning but include relationships between water resources and human cultural and economic livelihoods, including those of Indigenous communities. Since the mid-1980s there has been some provision for environmental flows in Chilean law. However, the legal and policy requirements are limited in scope and have been poorly implemented by regulatory institutions. In this article we critically examine the treatment of environmental flows in Chilean legal and policy frameworks. We argue that there is an urgent need for a comprehensive minimum flow regime in Chile to protect the environmental qualities of rivers, which must also reflect and provide for Indigenous water rights and interests. The developing constitutional crisis in Chile, the most significant political crisis since the end of the Pinochet dictatorship (1973–90), highlights the need to revisit the sensitive and unresolved issues of water governance and equity.

Over the past few years, the number of climate cases being filed against corporations and public authorities around the world has been on the rise. Aware of the central role of finance in economic development, the financial sector has remained vigilant. Traditionally, climate litigation in financial markets had been rare, but that seems to be changing: in 2018 there were more cases filed than in any previous year. The development of existing and forthcoming private and public sector initiatives with the aim of promoting sustainable finance may usher in even greater numbers in the next few years. This article provides the first systematic overview of climate cases in financial markets and introduces a typology to classify this type of climate case. This classification reveals common issues across different financial systems and raises questions for further enquiry that define a new research area within the emerging literature on climate litigation.

The recognition of rivers and related ecosystems as legal persons or subjects is an emerging mechanism in transnational practice available to governments in seeking more effective and collaborative natural resource management, sometimes at the insistence of indigenous peoples. This approach is developing particularly quickly in Colombia, where legal rights for rivers and ecosystems are grasping onto, and evolving out of, constitutional human rights protections. This enables the development of a new type of constitutionalism of nature. Yet legal rights for rivers may obscure the rights of indigenous peoples and their role in resource ownership and governance. We argue that the Colombian river cases serve as a caution to courts and legislatures elsewhere to be mindful, in devising ecosystem rights, of the complex and interrelated rights, interests and tenures of indigenous peoples and local communities.
