Climate policy in the shadow of national security
研究了一个净进口化石燃料的经济体在面临国家安全成本时，如何制定最优气候政策，发现最优碳税因化石燃料而异，国内生产应获补贴，而碳捕获与封存应被征税，绿色能源则不应补贴。
Historical events underscore that heavy reliance on foreign fossil fuel supply may come at a national security cost. The present study derives the optimal policy of a net fossil fuel importing economy with a binding climate target, when fossil fuel imports are associated with national security costs. The study shows that optimal carbon taxes are differentiated across fossil fuels and that domestic fossil fuel production should be subsidized. Further, carbon capture and storage should be taxed, while no subsidies should be granted to green energy production. These results contrast the typical climate policy recommendation of uniform carbon taxation.
