Climate policy and equity principles: fair burden sharing in a dynamic world

The paper argues that negotiation costs can prevent the international community from finding a new international climate agreement. To define a feasible way of facilitating the negotiation process, I analyze basic equity principles and their relationship to climate policy and economic development. Based on the most relevant principles, I propose a general synthetic rule for burden sharing in international climate policy. The rule avoids complexity and comprises both egalitarian and cost-sharing aspects, which appears to be crucial for achieving a climate agreement. Carbon budgets for the different countries are calculated under different parameter assumptions.
