I am writing to urge you to condemn the Trump administration's February 13, 2026 revocation of the 2009 Endangerment Finding and to introduce legislation that codifies the EPA's authority to regulate greenhouse gas emissions from the oil and gas industry. The 2009 Endangerment Finding was established following a 2007 Supreme Court ruling and provided the legal and scientific foundation for the EPA to regulate greenhouse gases under the Clean Air Act. It concluded, based on rigorous scientific evidence, that greenhouse gases threaten human health and welfare. This finding enabled the EPA to regulate emissions from fossil fuel use, power plants, vehicles, and other major pollution sources. The repeal strips the EPA of its legal authority to regulate emissions and contradicts decades of peer-reviewed scientific research. EPA Administrator Lee Zeldin justified this action by citing a report commissioned from known climate science deniers that used cherry-picked data and false citations to claim that greenhouse gas emissions do not contribute to climate change. This report absurdly asserts that vehicle price increases pose greater harm to the public than climate change itself. Without the Endangerment Finding, we face widespread deregulation that will accelerate climate change and expose communities to dangerous levels of pollution. The scientific consensus on climate change is overwhelming, and we cannot allow politically motivated pseudoscience to replace evidence-based policy. I am asking you to take three specific actions. First, publicly condemn this repeal and the flawed justification used to support it. Second, introduce or co-sponsor legislation that permanently codifies the EPA's authority to regulate greenhouse gas emissions into law, removing vulnerability to future administrative reversals. Third, reaffirm your commitment to science-based climate policy that protects public health. Climate change is real, and your constituents need you to act decisively to combat dangerous emissions and pollutants. The courts are expected to challenge this revocation, but Congressional action is essential to provide lasting protection.
