Environmental Protection Agency Administrator Lee Zeldin, in coordination with several other agencies, will announce Wednesday that he is overhauling the “Endangerment Finding,” a 2009 rule signed by Barack Obama’s EPA administrator Lisa Jackson that declared greenhouse gases constitute a threat to public health and human welfare under the Clean Air Act. National Review has exclusively learned that the agency’s reconsideration of the Obama-era finding will involve a massive overhaul of the regulations that fall under this rule, including vehicle emissions rules.

Zeldin’s move comes after President Trump signed an “Unleashing American Energy” executive order recommending reconsideration of the rule, along with a suite of other executive actions to withdraw from the Paris Climate Accords and end subsidies for electric vehicles.

Zeldin’s decision to upend the Endangerment Finding will also involve a wide-ranging reconsideration of dozens of climate-related rules, which the administrator will announce throughout the day. In a statement first shared with National Review, Zeldin described the move as a cost-cutting initiative to rid the agency of burdensome rules and regulations that have upped the cost of energy on American households.

“The Trump Administration will not sacrifice national prosperity, energy security, and the freedom of our people for an agenda that throttles our industries, our mobility, and our consumer choice while benefiting adversaries overseas,” Zeldin said. “We will follow the science, the law, and common sense wherever it leads, and we will do so while advancing our commitment towards helping to deliver cleaner, healthier, and safer air, land, and water.”
