WASHINGTON, July 29 (Reuters) – The Trump administration said on Tuesday it will rescind the long-standing finding that greenhouse gas emissions endanger human health, removing the legal foundation for all U.S. greenhouse gas regulations.
If finalized, the repeal would end current limits on greenhouse gas pollution from vehicle tailpipes, power plants, smokestacks and other sources, and hamper future U.S. efforts to combat global warming.
Environmental Protection Agency Administrator Lee Zeldin announced the agency’s plan to rescind the “endangerment finding” at an event at a car dealership in Indiana, alongside Energy Secretary Chris Wright, and called it the largest deregulatory action in U.S. history.
The proposal, which needs to undergo a public comment period, would cut $54 billion in costs annually through the repeal of all greenhouse gas standards, including the vehicle tailpipe standard, he said.
Under President Joe Biden, the EPA said the tailpipe rules through 2032 would avoid more than 7 billion tons of carbon emissions as it prodded automakers to build more EVs and provide nearly $100 billion of annual net benefits to society including $62 billion in reduced fuel costs, and maintenance and repair costs for drivers.
