Global Economic Damages from Climate Change and the Gains from Complying with the Paris Accord

Global Economic Damages from Climate Change and the Gains from Complying with the Paris Accord

Wednesday, 10 October 2018 - 11:00am to 12:00pm

Economists have largely underestimated the global economic damages from climate change. Our work develops a large dimensional global trade model to account for various effects of global warming on national incomes for 139 countries, showing considerable global economic damages from climate change and relative gains from complying with the Paris Accord. Global economic damages, for example, range from $9.5 to $23 trillion per year in 2100, depending on temperature increase, and gains from complying with a 2-degree target relative to ‘business as usual’ are US$17+ trillion per year, even with limited damage functions. Model outcomes also show that South Asia, Southeast Asia and Africa are severely impacted at all temperature increases, underscoring the point that many poorer countries are the ones most impacted by climate change. The framework is extended to account for cumulative global damages which range from $271 to $604 trillion from now to 2100.
