This introduction lays out the context, scope, theoretical framework, core arguments and structure of the study. It problematises the focus on synergies between environmental protection and human rights in existing literature, and emphasises the importance of retrieving, exploring and critically unpacking the conflicts that underpin this relationship. The analysis introduces the central interrogation of the book: how environmental protection laws can collide with human rights concerns, and how regional human rights courts balance individual or collective human rights against the interest in environmental protection, when environmental protection and human rights collide. Several sub-questions unfold from this main interrogation. How do regional human rights courts address, conceive of and frame conflicts with environmental laws, many of which include considerations that are part and parcel of existing human rights? Which conflict-management techniques and argumentative strategies do they employ to settle such trade-offs? And what does this tell us about how the environment is represented, and how its protection is legally justified in relation to human concerns? The summary of the main findings of the book lay bare the importance of the project, the gaps it aims to fill, and how these novel insights reconfigure the relationship between environmental protection and human rights.

This concluding chapter summarises the main arguments and findings of the book. It reflects on the multiple rationales and ideals that were mobilised over time to protect the environment, and translates this protection into an actionable legal framework. It examines the motivations and aims invoked to this end and explores what implications the gradual association of environmental protection with human rights in regional human rights jurisprudence had for the representation of the environment and its relation to human concerns. How are environmental concerns conceptualised, consolidated and contested by human rights courts? Which representations of human and non-human relations lie encoded in the ‘universalisation strategies’ that the book reveals? And what are the political effects of the adoption of environmental concerns in the lexicon of human rights? The conclusion interrogates the world-making effects that the articulation of environmental protection in a human rights register generates and questions the latter’s suitability for radical environmental politics in the Anthropocene. Overall, the book informs us about the management of legal conflicts by courts, the strategies they develop to justify their outcomes and the performative role they play in shaping our understanding of the environment–human rights interface.

When environmental protection and human rights collide, regional human rights courts balance the competing interests at stake to determine optimal outcomes. In doing so, courts tend to frame environmental protection as a ‘general interest’ capable of limiting relative fundamental rights and freedoms. This construction of an integrated, common and shared social value is loaded with political agency. In dictating specific outcomes as being in the ‘general’ interest, this adjudicative practice projects particular ideals into the realm of universality. This chapter traces the origins and meanings of the general interest, its attribution to environmental protection and, most importantly, its invocation by regional human rights courts when solving conflicts between environmental and human rights concerns. The ability of judges to reframe the particular in universal terms through the heuristic of the ‘general interest’ is assessed in the light of Martti Koskenniemi’s theory on the (discursive) hegemony of international legal argumentation. When courts frame particular substantive, aesthetic or procedural dimensions of environmental protection as being in the general interest, they produce a hegemonic vision of the environment–human rights interface, which is continuously reproduced through judicial cross-referencing. Thereby, values set under established case law gradually crystallise into patterns, precedents and social norms.
