Wyden, Colleagues Sound Alarm on EPA’s Plot to Rollback Decades of Scientific Findings on Greenhouse Gases

Washington, D.C.—U.S. Senator Ron Wyden, D-Ore., today led 12 Senate Democrats in raising the alarm over reports that the Environmental Protection Agency (EPA) intends to roll back its findings that greenhouse gases endanger people’s health and welfare.
In their letter to EPA Administrator Lee Zeldin, the senators emphasized,“It is difficult to understand how the nation’s lead official responsible for protecting human health and the environment could seriously entertain the idea of undoing a scientific finding that has been repeatedly upheld in court, reinforced by thousands of studies and decades of research, and is supported by the vast majority of the scientific community.”
The move to overhaul decades of overwhelming scientific consensus on the climate crisis and natural disasters follows another recordhot year, as well as catastrophic wildfires that destroyed lives and communities across the West Coast. The senators expressed serious concerns about the political motives behind the decision.
“Using political means to hinder, distort, or improperly steer the work of federal scientists or the communication of scientific facts undermines the public trust of key institutions and actively threatens the welfare of the nation. The scientific evidence in support of the endangerment finding is clear, compelling, and continues to grow stronger. Reversing this finding would be reckless and irrational,”the senators wrote.
Before the EPA takes any further steps to undo this foundational finding without transparency and scientific support, the senators demand answers to the following questions by March 15, 2025:
Senator Wyden was joined by Senate Energy and Natural Resources Committee Ranking Member Martin Heinrich, D-N.M., and Senate Democratic Whip Dick Durbin, D-Ill., as well as Senators Tammy Duckworth, D-Ill., Mazie Hirono, D-Hawai’i, Jeff Merkley, D-Ore., Patty Murray, D-Wash., Brian Schatz, D-Hawai’i, Tina Smith, D-Minn., Chris Van Hollen, D-Md., Peter Welch, D-Vt., Cory Booker, D-N.J., and Edward J. Markey, D-Mass.
