U.S. Senator Mazie K. Hirono, along with Senator Ron Wyden and 11 other senators, has expressed concern over the Environmental Protection Agency's (EPA) reported intention to revise its stance on greenhouse gases. The lawmakers addressed their concerns in a letter to EPA Administrator Lee Zeldin.
The senators questioned how the head of an agency responsible for environmental protection could consider reversing a scientific finding that has been upheld by courts and supported by extensive research. They highlighted the consequences of ignoring scientific consensus, especially after another year marked by extreme weather events.
"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," they wrote. They also demanded answers regarding any new evidence that would justify such a reversal and how it aligns with EPA’s mission.
The group urged Administrator Zeldin to provide clarity on several points by March 15, 2025, including what new scientific evidence supports this decision and how legal precedents will be addressed. The letter was signed by Senators Cory Booker, Tammy Duckworth, Dick Durbin, Martin Heinrich, Chris Van Hollen, Ed Markey, Jeff Merkley, Patty Murray, Brian Schatz, Tina Smith, and Peter Welch.
The senators reiterated their commitment to ensuring decisions are made based on science rather than political pressure: "As the Administrator of the EPA, you are tasked with making decisions grounded in science, law, and the best interests of the American people."
They concluded by urging a reconsideration of any plans to overturn established findings related to climate change impacts.
