U.S. Environmental Protection Agency (EPA) Administrator Lee Zeldin is expected to announce the agency’s final decision to rescind the 2009 “Endangerment Finding” today.

The Trump administration has proposed rescinding the finding—an underlying scientific determination that supports climate-related regulations—despite thousands of comments opposing the move, most of which cited the harm it would pose to communities and working people. The finding underpins the regulations that limit greenhouse gas pollution in nearly every sector of our economy.

Ahead of the announcement, the BlueGreen Alliance released a statement from Executive Director Jason Walsh:

“Billionaires like Donald Trump don’t suffer the devastation of climate change. Working people do. Today’s action by President Trump, if unchecked by the courts or Congress, will put more money in the pockets of the CEOs who pollute our air and cut big checks for Republican politicians. But it will put more regular folks in the hospital or force them to flee climate disasters while the billionaire class is safely protected on their mountaintops and private islands.”
