Optimising climate change mitigation through international cooperation
The climate change deal reached through the Paris Agreement remains uncertain due to the potential withdrawal of the U.S., which could trigger a domino effect in other nations. This calls for new mechanisms to enable a resilient cooperative response to climate change mitigation at a global level. Now a group of researchers from Imperial College, The University of Manchester and Carnegie Mellon University have proposed an approach to aid future negotiations based on the optimal quantification of the benefits of cooperation and their fair distribution among the parties involved. The proposed approach was applied to the US Clean Power Plan to elucidate the value of cooperation when reducing US carbon emissions from the power sector. The researchers found that, even with only a few states cooperating, significant economic and environmental benefits can be attained. A fair sharing of the cooperation dividends allows all states to benefit economically, which may act as a compensation mechanism to spur collective action. This approach can help to strengthen transboundary cooperation and to maintain the momentum in global action for mitigating climate change.
