Abstract

Treaty Norms and Climate Change MitigationDarrel MoellendorfCurrently the international community is discussing the regulatory framework to replace the Kyoto Protocol after 2012. The unveiling of the new framework is scheduled to occur at the December 2009 COP in Copenhagen. The stakes are high, since any treaty will affect the development prospects of per capita poor countries and will determine the climate change–related costs borne by poor people for centuries to come. Failure to arrive at an agreement would have grave effects on the development prospects of poor countries, many of which will experience the most severe effects of climate change. The original UNFCCC treaty recognizes these kinds of concerns and requires that further treaty negotiation pay them heed. Any agreement will be required to conform to UNFCCC norms related to sustainable development and the equitable distribution of responsibilities. In this paper I argue that UNFCCC norms tightly constrain the range of acceptable agreements for the distribution of burdens to mitigate climate change. I conclude that any legitimate treaty must put much heavier mitigation burdens on industrialized developed countries. Of the various proposals that have received international attention, two in particular stand out as possibly satisfying UNFCCC norms regarding the distribution of responsibilities.
