After the ICJ's Landmark Climate Ruling, a New Book Asks Why Environmental Rights Still Don't Deliver
On 23 July 2025, the International Court of Justice issued its long-awaited Advisory Opinion on the Obligations of States in Respect of Climate Change — a ruling widely described as a turning point for climate and environmental rights law. The ICJ found that international law imposes binding obligations on states to prevent significant climate harm, that the Paris Agreement's 1.5°C target carries legal force, and that inadequate climate action can itself amount to a violation of fundamental rights to life, health and an adequate standard of living. For the first time, the world's highest court connected environmental protection directly to enforceable state responsibility, including reparations.
That ruling gives fresh urgency to Environmental Rights: Recognition, Implementation, Outcomes and Alternatives, by James R. May (Edward Elgar Publishing, July 2026). May's empirically grounded study asks the question the ICJ opinion now makes unavoidable: recognition of a right is not the same as its enforcement. Drawing on jurisdictions worldwide, the book identifies exactly where environmental rights provisions stall — judicial reluctance, textual ambiguity — and maps the alternative legal pathways that fill the gap: socioeconomic and dignity rights, rights of Nature, procedural participation rights, and sustainability protections.
The book's relevance is immediate and practical. Litigators bringing climate claims after the ICJ opinion now have a comparative playbook for which rights framework is likely to hold up in a given jurisdiction. Policymakers drafting or reforming constitutional environmental rights provisions can see, empirically, which formulations have translated into real outcomes and which have not. And scholars tracking the post-ICJ wave of domestic climate litigation gain a rigorous account of the doctrinal alternatives courts are likely to reach for next.
For academic and institutional law libraries, this is a natural companion to any environmental law, human rights, or climate law collection — a 2026 release that engages directly with the single most significant environmental law ruling of the past year.

Q&A
What did the ICJ's 2025 climate advisory opinion actually decide?
The ICJ ruled that international law imposes binding obligations on states to prevent significant climate harm, that the Paris Agreement's 1.5°C target carries legal force, and that inadequate climate action can violate fundamental human rights.
Why do environmental rights often fail to translate into enforceable protections?
Implementation is frequently blunted by judicial reluctance to enforce open-textured provisions and by ambiguity in how those provisions are drafted — the central empirical finding of this book.
What is the difference between environmental rights and rights of Nature?
Environmental rights are typically held by people, while rights of Nature vest legal standing in natural entities themselves — one of several alternative frameworks the book examines.
How does the ICJ climate ruling affect environmental rights litigation?
By establishing that inadequate climate action can breach binding legal obligations and human rights, the ruling gives litigants stronger legal grounding for climate and environmental rights claims worldwide.
