A critical review of “ 2 degree target ” and a desirable and feasible post-Kyoto international framework

This paper begins with the paradigm shift from top-down to bottom-up approach in Copenhagen in 2009. Then 2 degree target as the ultimate objective of response strategies under UNFCCC is reviewed from both vertical balance (purely climate change view point) and horizontal balance (view point of efficient allocation of scarce resources) and the paper finds the target is unrealistic and isn’t based on much science. The paper argues to have new Post-Kyoto international framework through pledge and review approach based on the alternative target that is scientifically sound, economically reasonable and politically feasible.
