Distributional Equity in Climate Change Policy: Responsibility, Capacity, and Vulnerability. Dustin Tingley, February 3, 2016, Paper. "Bargaining over the allocation of costs to curb the effects of climate change has proven difficult, as evidenced by repeated failures to reach an international agreement. Sadly, the longer it takes to produce an agreement, the more likely it is that climate change will impose significant costs on all countries. We argue that a successful agreement will allocate costs to countries based on three dimensions of distributional equity: their capacity to pay to curb the effects of climate change, their vulnerability to the negative effects of climate change, and their responsibility for causing climate change."
