Reversing Environmental Rollbacks

The Trump Administration rolled back environmental protection in numerous ways, large and small, across the entire federal government. From power plant mercury emissions to protection for endangered species, the administration undermined the process, structure, and substance of environmental law, regulation, and protection. Most of these rollbacks can be reversed by the Biden administration, but it will take concerted effort. CLEE has compiled 200 rollbacks based on the tracking information from Columbia Law School’s Sabin Center, Harvard Law School, and other sources. We have also analyzed a subset of “Day 2” actions potentially subject to immediate reversal, and prepared a set of recommended action memos for certain high-priority, high-complexity issues.

With the Biden administration now in office, this website will track their progress as they begin the process of addressing each rollback over the first months of 2021. On January 20, 2021, President Biden issued executive orders addressing a suite of climate change policies and regulatory review processes, a memorandum directing agencies to update their regulatory reviews to reflect administration priorities, and a fact sheet identifying agency actions for regulatory review; and the Office of Management and Budget issued a memorandum to all agencies instituting a “regulatory freeze” pausing all Trump-era rules still pending until they are reviewed by members of the new administration.

We encourage suggestions and comments, particularly identification of rollbacks that might be missing from the list. Please send any and all ideas to
