Foreword to the TEL Fifth Anniversary Issue: Re-evaluating the Principle of Common but Differentiated Responsibilities in Transnational Climate Change Law

Abstract

The principles of equity and common but differentiated responsibilities must remain the bedrock of our collective enterprise across all areas: mitigation, adaptation and means of implementation. Anything else would be morally wrong. Narendra Modi, Prime Minister of India COP-21 Leaders Meeting, November 2015 If we keep our eye on this core objective [that we must act to avoid dangerous climate change], the imperative of bringing all major emitters into a regime of climate commitments is clear. There is simply no other way to head off the coming crisis. As I have said before - just do the math. Todd Stern, US lead negotiator, Comments to the Center for American Progress, February 2010.
