The ultimate objective of climate response strategies, and a desirable and feasible international framework

Abstract

In this chapter, the author examines the appropriateness and feasibility of the so-called 2 degree target as the ultimate objective of climate response strategies under Article 2 of the UNFCCC. Thereafter, a desirable and feasible international framework is discussed. First, the author presents a brief history and various interpretations of the Article 2 of the UNFCCC, and then examines the target from a purely climate change viewpoint (vertical balance), followed by another viewpoint of efficient allocation of scarce resources (horizontal balance). Based on the above analysis, the author tries to work out a desirable and feasible Post-Kyoto international framework. The author finds the top-down approach typically embodied in the Kyoto Protocol has failed. Finally, the author concludes global leaders should revisit the target, as the 2 degree target has no solid foundation and is not feasible. And, as for the international framework, the author argues for pursuing a bottom-up approach (pledge and review) that came out at the end of Copenhagen negotiation process. The author further argues all efforts, such as contribution in the field of adaptation, technology development and diffusion, and financing, should be integrated with mitigation efforts. © Springer-Verlag London 2012.
