The Relevance of the No-Harm Principle to Climate Change Law and Politics

Although the no-harm principle has been identified as the cornerstone of international environmental law, it has not generally been recognized as a central feature of international climate change governance. Enduring disagreements as to the relevant normative principles to international cooperation have long plagued international climate change negotiations.

It thus suggests that the climate regime should be framed as a regime recognizing obligations and responsibilities rather than a regime of voluntary participation and assistance. The article includes a detailed account of the reception of the no-harm principle in climate negotiations, a response to three likely objections to the relevance of the no-harm principle, and some reflections on a possible, realistic interpretation of the no-harm principle in relation to climate change
