Since 2017, the Trump administration targeted many regulations which had been put in place to address climate change. A handful of major climate rules reversed or weakened under Mr. Trump could have a significant effect on future emissions. The New York Times has been covering the more than 100 environmental rules being repealed or weakened, and reported on 9/17/2020, that these rollbacks are expected to result in an additional 1.8 billion metric tons of greenhouse gases in the atmosphere by 2035.

Columbia’s Sabin Center for Climate Change Law has posted a Deregulation Tracker as well as a Climate Regulation database detailing regulations and other efforts undertaken by federal agencies to address the causes and impacts of climate change. Harvard is tracking, too.

President Joe Biden has his work cut out for him dealing with the many rollbacks that occurred under the Trump Administration. The Washington Post is tracking the success President Biden is having as he unwinds Trump’s legacy and forges his own.


The list below highlights some of the many policies enacted under the
Biden administration and those overturned.
