NYT: The Trump Administration Is Reversing Nearly 100 Environmental Rules. Here's the Full List.

NYT:

After three years in office, the Trump administration has dismantled most of the major climate and environmental policies the president promised to undo.

Calling the rules unnecessary and burdensome to the fossil fuel industry and other businesses, his administration has weakened Obama-era limits on planet-warming carbon dioxide emissions from power plants and from cars and trucks, and rolled back many more rules governing clean air, water and toxic chemicals. Several major reversals have been finalized in recent weeks as the country has struggled to contain the spread of the new coronavirus.

In all, a New York Times analysis, based on research from Harvard Law School, Columbia Law School and other sources, counts more than 60 environmental rules and regulations officially reversed, revoked or otherwise rolled back under Mr. Trump. An additional 34 rollbacks are still in progress.

(...)

Below, we have summarized each rule that has been targeted for reversal over the past three years.

I don't know if it will ever be possible to undo all the damage done by trump and the republicans.
