The central motivation of this project is the argument that an equitable framework is a precondition for an effective climate regime. Without fairness of a particular type specifically, developmental justice, it will not be possible to win the earnest engagement of the developing world, which is necessary for a successful global response to the climate problem. This project will continue and extend the work of the Greenhouse Development Rights project. It aims to instill a perspective of developmental equity into the climate discourse and negotiations, by providing an appropriate framing and the necessary technical, analytical and political substantiation.
