"Sharing Global CO2 Emission Reductions Among One Billion High Emitters"
Journal Article, Proceedings of the National Academy of Sciences of the United States of America
By Shoibal Chakravarty, Ananth Chikkatur, Associate, Energy Technology Innovation Policy, Heleen de Coninck, Stephen Pacala, Robert Socolow and Massimo Tavoni
The 1992 United Nations Framework Convention on Climate Change (UNFCCC) created a 2-tier world. It called upon the developed ("Annex I") countries to "take the lead" in reducing carbon emissions, and, under the principle of "common but differentiated responsibilities," established no time frame for developing countries to follow. However, a consensus is now emerging in favor of low stabilization targets. These targets cannot be achieved without the participation of developing countries, which today emit about half of global CO2 emissions and whose future emissions increase faster than the emissions of industrialized countries under "business as usual" scenarios.

"Modeling Economic Impacts of Alternative International Climate Policy Architectures: A Quantitative and Comparative Assessment of Architectures for Agreement"
Discussion Paper
By Valentina Bosetti, Carlo Carraro, Alessandra Sgobbi and Massimo Tavoni
This paper provides a quantitative comparison of the main architectures for an agreement on climate policy. Possible successors to the Kyoto protocol are assessed according to four criteria: economic efficiency; environmental effectiveness; distributional implications; and their political acceptability which is measured in terms of feasibility and enforceability. The ultimate aim is to derive useful information for designing a future agreement on climate change control.

"Equity and Climate Policy: An Allocation Method Based on Individual Emissions"
Presentation
By Shoibal Chakravarty, Ananth Chikkatur, Associate, Energy Technology Innovation Policy and Massimo Tavoni
The speakers presented a new framework for allocation of a global carbon reduction target among nations, in which "common but differentiated responsibilities" refers to the emissions of individuals, rather than of nations.
