This discussion paper draws on papers prepared by the institute to inform the deliberations of the International Climate Change Taskforce, a collaboration between the institute and two other think tanks, the Institute for Public Policy Research and the Center for American Progress. For the post-2012 period, the paper recommends the development of a new global plan that builds on the United Nations Framework Convention on Climate Change and the Kyoto Protocol, and works to involve all countries in action on climate change at the international level over the coming decades. It would be developed as part of the ongoing UN climate negotiations.
