Thirty years of international climate cooperation have had a significant impact, including an extraordinary effort to clarify the science, global agreement of a stabilisation target, an international treaty basis for mitigation and adaptation action.

This paper presents a set of scenarios that simulate different mitigation commitments made by G20 countries for 2030 and mid-century and the resulting impacts on global temperature rise.

As a growing number of countries bring forward national net-zero targets, questions of how much carbon dioxide removal each nation holds responsibility for, and whether transfers should be possible under the Paris Agreement market mechanisms become increasingly important.

This article tests fairness justifications offered in 168 nationally determined contributions to the 2015 Paris Agreement against the touchstone of principles of international environmental law and finds some justify their contributions on the basis of indicators not backed by such principles.
