Trump Administration Proposes Repeal Of Obama’s Climate Change Endangerment Finding

The Trump administration recently unveiled a proposal to repeal the 2009 “Endangerment Finding,” a controversial U.S. climate policy that declared carbon dioxide and other greenhouse gases a threat to public health and welfare.

The Environmental Protection Agency’s (EPA) proposed rule, if finalized, would dismantle the legal foundation for numerous climate regulations under the Clean Air Act, repealing all resulting greenhouse gas emissions regulations for motor vehicles and engines.

EPA Administrator Lee Zeldin described the move as “the largest deregulatory action in the history of America,” arguing that the Endangerment Finding has been misused to impose costly regulations.

“There are people who, in the name of climate change, are willing to bankrupt the country,” Zeldin said. “They created this endangerment finding, and then they are able to put all these regulations on vehicles, on airplanes, on stationary sources, to basically regulate out of existence, in many cases, a lot of segments of our economy. And it cost Americans a lot of money.”

The proposal, which follows an executive order from President Trump, directs the EPA to review the findings’ legality. It is part of a broader push to roll back 31 environmental regulations.

Zeldin criticized the Obama and Biden administrations, saying they “twisted the law, ignored precedent, and warped science to achieve their preferred ends and stick American families with hundreds of billions of dollars in hidden taxes every single year.”

In states like Arizona, the Endangerment Finding has been used to enforce mandates and shut down energy sources that Arizona relies on.

The Arizona Free Enterprise Club celebrated the EPA’s proposal, viewing it as a critical step toward alleviating economic burdens imposed on Arizona families and businesses from overreaching environmental mandates.

The Club argues that the Endangerment Finding has forced the closure of reliable energy facilities and imposed costly environmental policies that have led to soaring utility costs and raised concerns about the reliability of the state’s energy grid.

Scot Mussi, President of the Arizona Free Enterprise Club, reacted to the Trump administration’s proposal, saying, “[The Endangerment Finding] has always been junk science used to shut down Arizona’s economy, close down our coal plants, and force our state into California-style green mandates. Repealing the Endangerment Finding is a necessary step to restore energy independence, protect ratepayers, and stop the unelected bureaucrats at the EPA from hijacking our economy in the name of climate alarmism.”
