The emerging discussion on international climate policy after 2012 (the end of the first commitment period of the Kyoto Protocol) has generated a number of approaches. Many of these are only now being analysed.

This report provides a comprehensive yet succinct overview of 43 different approaches to international climate efforts. Following an overview of key issues, each approach is explained in terms of its rationale, forum, time frame, mitigation commitment, institutional arrangements and other elements.

The document provides a reference guide to the essential characteristics of post-2012 climate approaches. It is most useful, and key reading for anyone interested in climate policy.
