Exchanging Goods and Damages: The Role of Trade on the Distribution of Climate Change Costs

Abstract: The impacts of climate change vary significantly across world regions. Whereas tropical and subtropical regions are expected to suffer severely from the effects of climate change, the impacts in northern latitudes should remain relatively moderate. However, regions are not self-sufficient, and the costs of climate change can spread across regions through international trade. I study the international spillover of climate impacts within a regionalised, climate-sensitive, dynamic computable general equilibrium model of the world economy. Using data from a global climate model shows that the world regions face welfare losses between 0.6 and 2.1 % due to climate change. I also show that climate change affects terms of trade and sectoral competitiveness. By means of a decomposition method, the extent of spillover impacts through international trade can be identified. Spillover impacts significantly affect, either positively or negatively, the total costs of climate change for a region. For regions with low exposure to climate change and high adaptive capacities, spillover effects are responsible for a 1/6 of the total cost of climate change.
