The November 5 election was the worst-case outcome for climate regulation. The return of Donald Trump to the Oval Office and Republican control of the Senate and the House of Representatives will halt federal progress and lead to a reversal of most of the climate initiatives undertaken by the Biden administration.

Such a rollback occurred after Trump first won election in 2016, but this time the stakes are even higher. Trump has promised to halt spending under the 2022 Inflation Reduction Act, the landmark climate law that dramatically increased federal support for clean energy technology and electric vehicles.

Rapid advances in the technology and economics of clean energy have created a momentum that can be slowed but not stopped, with the cost of solar dropping globally by more than half since 2016. States and cities still retain much ability to reduce emissions and to prepare for the worsening physical impacts of climate change. But major progress will be in jeopardy because of the administration’s actions on a host of fronts. [Continue reading…]
