In contrast to the large amount of attention that FERC’s consideration of climate change in natural gas permitting has received, there has been relatively little paid to how FERC does and should consider climate change in hydropower permitting. This Comment fills a gap in the literature by analyzing how FERC considers climate change during permitting for hydropower projects. And it offers suggestions for how FERC could better handle this subject, either now or under a future administration, by analyzing the emissions impact of hydropower projects in a more detailed manner, investing more resources in studying the impacts that climate change will have on hydropower projects, and altering its license reopener provisions.
