the nation\u2019s climate and clean air protections.<\/p>\n<p>Buried in one of these orders is direction to the Environmental Protection Agency to make recommendations by February 19th on the \u201clegality and continued applicability\u201d of EPA\u2019s Endangerment Finding.<\/p>\n<p>The Endangerment Finding is EPA\u2019s science-based determination that greenhouse gases \u2013 the pollution that causes climate change \u2013 harm public health and welfare.<\/p>\n<p>The directive to reconsider the Endangerment Finding comes straight from Project 2025 and is both cynical and deeply concerning given the mountain of scientific evidence supporting the Finding, the devastating climate harms Americans are experiencing right now, and EPA\u2019s clear obligation to protect Americans\u2019 health and welfare.<\/p>\n<p>Shortly after receiving President Trump\u2019s directive, EPA\u2019s acting Administrator summarily fired the agency\u2019s independent Science Advisory Board \u2013 the very scientists who can speak to the extensive scientific basis supporting EPA\u2019s Endangerment Finding.<\/p>\n<p>The real-world consequences of any effort by EPA Administrator Lee Zeldin and the Trump administration to destabilize the Endangerment Finding would be severe and unlawful and would hurt Americans across the country.<\/p>\n<p><strong>What is the Endangerment Finding?<\/strong><\/p>\n<p>In 2007, the Supreme Court determined that greenhouse gases are air pollutants within the unambiguous meaning of the Clean Air Act and that EPA must make a science-based determination as to whether greenhouse gas pollution endangers public health and welfare.<\/p>\n<p>Following the Supreme Court\u2019s decision, in 2009, EPA issued the Endangerment Finding, which determines that climate pollution <a href=\"https:\/\/nam11.safelinks.protection.outlook.com\/?url=https%3A%2F%2Fwww.edf.org%2Foverview-epa-endangerment-finding&amp;data=05%7C02%7Cpzalzal%40edf.org%7C2f5b5baa3bcd4bb2b30708dd3f13bdc3%7Cfe4574edbcfd4bf0bde843713c3f434f%7C0%7C0%7C638736076205982916%7CUnknown%7CTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ%3D%3D%7C0%7C%7C%7C&amp;sdata=vcM0lCJ3NPosMO3uNcpaZYX5Upuqo9mrPc%2BAZZKL1nk%3D&amp;reserved=0\">threatens the public health and welfare<\/a> of current and future generations.<\/p>\n<p>Here are a few things you should know about EPA\u2019s finding:<\/p>\n<p><strong>It\u2019s supported by extensive science<\/strong><\/p>\n<p>The Endangerment Finding is based on a vast amount of scientific evidence that climate pollution harms human health. It was adopted after extensive public process, including multiple opportunities for public input and evaluation of more than 380,000 public comments.<\/p>\n<p>The final Endangerment Finding includes detailed information confirming that greenhouse gas pollution is driving destructive changes in our climate that pose a grave and growing threat to Americans\u2019 health, security, and economic well-being, both now and in the future. These include health harms from increased smog, rising temperatures and extreme weather events, among other things.<\/p>\n<p>Over time, the scientific evidence has only become stronger. The intergovernmental expert body charged by Congress with assessing the impacts of climate change on the United States has issued a series of National Climate Assessments, most recently by the Trump Administration in 2018 and the Biden Administration in 2023. The National Climate Assessments confirm that climate change resulting from greenhouse gas emissions is causing extensive, and increasingly severe harms throughout the country.<\/p>\n<p>EPA has also continued to document the science behind greenhouse gases\u2019 contributions to climate change, including in earlier responses to requests that it reevaluate the Endangerment Finding (<a href=\"https:\/\/www.epa.gov\/climate-change\/2010-denial-petitions-reconsideration-endangerment-and-cause-or-contribute-findings\">here<\/a> and <a href=\"https:\/\/www.epa.gov\/climate-change\/2022-denial-petitions-reconsideration-rulemaking-or-reopening-endangerment-and-cause\">here<\/a>) and in multiple actions establishing pollution standards for <a href=\"https:\/\/www.govinfo.gov\/content\/pkg\/FR-2024-05-09\/pdf\/2024-09233.pdf\">power plants<\/a>, cars and <a href=\"https:\/\/www.govinfo.gov\/content\/pkg\/FR-2024-04-22\/pdf\/2024-06809.pdf\">freight trucks<\/a>, and <a href=\"https:\/\/www.govinfo.gov\/content\/pkg\/FR-2024-03-08\/pdf\/2024-00366.pdf\">oil and gas facilities<\/a> \u2013 some of which include scientific assessments that were completed within the last year. \u00a0And in legal filings supporting these actions, climate scientists have <a href=\"https:\/\/library.edf.org\/asset-management\/286XC56I3OMW\">pointed to very recent scientific evidence<\/a> that even more strongly confirms these climate pollution harms.<\/p>\n<p>In short, the science unequivocally supports what so many Americans are already experiencing \u2013 climate pollution is causing harm in communities across the country. There is no question about the Endangerment Finding\u2019s \u201ccontinued applicability.\u201d<\/p>\n<p><strong>Courts have repeatedly affirmed its Legalit<\/strong>y<\/p>\n<p>Unsurprisingly, given the extensive evidence supporting it, courts have uniformly rejected legal challenges to the Endangerment Finding.<\/p>\n<p>For instance, the <a href=\"https:\/\/www.epa.gov\/sites\/default\/files\/2021-05\/documents\/09-1322-1380690.pdf\">finding was upheld<\/a> by the D.C. Circuit Court of Appeals in 2012. Industry groups had challenged EPA\u2019s use of scientific assessments, but the court held that EPA\u2019s findings were supported by substantial evidence and that the agency had considered the scientific evidence before it in \u201ca rational manner.\u201d<\/p>\n<p>Then the Supreme Court denied petitions for certiorari (review) that raised challenges to the Endangerment Finding in October 2013.<\/p>\n<p>More recently, the D.C. Circuit again rejected challenges to the finding and the Supreme Court again denied review.<\/p>\n<p>The findings have been the basis of agency decisions across administrations of both parties and have been the basis of numerous judicial decisions. As to the Endangerment Finding\u2019s \u201clegality,\u201d the answer is also a clear and unequivocal \u201cyes.\u201d<\/p>\n<p><strong>Commonsense steps to cut pollution, protect communities<\/strong><\/p>\n<p>Beyond being grounded in the science, law, and the everyday experience of many Americans, the Endangerment Finding is important because it empowers EPA to do its job \u2013 protecting Americans from harmful climate pollution.<\/p>\n<p>EPA has done just that since adopting the Endangerment Finding by taking commonsense steps to reduce climate pollution from large sources like power plants, cars and trucks, and oil and gas operations. These actions have been <a href=\"https:\/\/library.edf.org\/AssetLink\/50462bt0j031m7mr34l5k3jtn6146quo.pdf\">enormously successful<\/a> in reducing pollution and delivering immediate benefits to Americans across the country.<\/p>\n<p>It is vital that these commonsense measures remain in place. <a href=\"https:\/\/library.edf.org\/AssetLink\/50462bt0j031m7mr34l5k3jtn6146quo.pdf\">Recent EDF analysis<\/a> looks at 11 key actions (including the foundational EPA climate protections mentioned above) that together will reduce more than 28 billion metric tons of climate pollution by 2055. That\u2019s almost five times the total amount of annual emissions from the United States today.<\/p>\n<p><strong>New threats to the Endangerment Finding<\/strong><\/p>\n<p>President Trump\u2019s efforts to reverse the Endangerment Finding come straight from Project 2025 \u2013 the infamous policy playbook crafted in part by Russell Vought, the new head of the White House\u2019s Office of Management and Budget. Targeting the Endangerment Finding is extreme, dangerous, and puts the important benefits mentioned above at risk. It also goes well beyond anything the first Trump administration undertook.<\/p>\n<p>Undermining the Endangerment Finding would be inconsistent with the commitments EPA Administrator Zeldin made during his confirmation hearing. Despite EPA\u2019s recent dismissal of its independent Scientific Advisory Board, Administrator Zeldin affirmed that \u201cI am someone who believes strongly that we should work with the scientists, leaving the science to the scientists \u2026 Fortunately, at EPA, we do have many talented scientists who provide that research.\u201d <a href=\"https:\/\/www.epw.senate.gov\/public\/_cache\/files\/c\/4\/c4282a20-59a6-4523-bcd3-f692ffd133c9\/BA023DD60A07E4B417B6DA9813A57307AECB8171E9B518601F316BC288B4C10F.spw-01162025-nomination-of-hon-lee-zeldin-.pdf\">(Senate EPW Committee transcript<\/a> page 34) He repeatedly committed to \u201chonoring our obligations under the law,\u201d and said that \u201cwe will have never done enough to ensure that our water and our air is clean, safe, and healthy.
