The Biden administration is expected to unveil the final version of one of its most pivotal climate rules next week — a clean car rule that could result in two-thirds of new passenger vehicles sold in 2032 running on electricity.

The Environmental Protection Agency has invited environmental and public health groups to an event Wednesday with Administrator Michael Regan to announce the regulation, according to three people with knowledge of the agency’s timing, who were granted anonymity to discuss the still-unpublicized action.

The announcement concerns “EPA’s work to address climate change, improve air quality and protect public health,” according to the invite, which POLITICO’s E&E News reviewed.


The regulation on passenger cars and light trucks, first announced last spring, is a cornerstone of the Biden administration’s campaign to address climate change. Transportation is the nation’s biggest source of carbon dioxide and other heat-trapping gases, and passenger cars and trucks account for most of those emissions.
