In October, the Trump administration put forward a decision to repeal the Clean Power Plan, citing analysis showing that the costs of the rule exceed its benefits. This analysis laid out several important precedents that are relevant not only for the Clean Power Plan but also for regulatory analysis in general. These include a revised estimate of the social cost of carbon that changes the calculation of the climate benefits from reducing carbon dioxide emissions, as well as different approaches for the treatment of ancillary public health benefits, the savings from improved fuel efficiency, and more.
This RFF seminar explored the implications of each of these revisions for potential future climate and energy policy decisions. RFF’s Alan Krupnick reflected on the decision’s treatment of health benefits, and Harvard University’s Kathy Fallon Lambert presented new research on how repealing the Clean Power Plan would impact public health. RFF’s Dallas Burtraw concluded the seminar with a discussion of how a revised “inside the fence line” approach to Clean Power Plan compliance might work.
