EPA Chief Lee Zeldin Defends Repeal of Climate Endangerment Finding at Heartland Conference

EPA Administrator Lee Zeldin used a Wednesday keynote at a Heartland Institute conference of climate‑policy skeptics to defend his agency’s repeal of the 2009 greenhouse‑gas "endangerment finding" and told attendees they should "celebrate vindication." The Trump EPA earlier this year revoked the finding, which for 16 years had been the legal basis for regulating planet‑warming emissions from power plants, vehicles and other sources under the Clean Air Act, arguing prior administrations twisted science and that the determination hurt industry and the broader economy. Zeldin framed the move as overturning decades of "unthinking adherence" to liberal politicians and environmental groups, while an EPA spokeswoman said the agency no longer views itself as a vehicle for "radical ideology" and claims it is now guided by "gold standard science, not doomsday models." Environmental groups, including the Environmental Defense Fund, blasted Zeldin for "rallying climate deniers" at Heartland — a conservative think tank funded in part by fossil‑fuel interests that rejects mainstream climate science — and warned the repeal abandons EPA’s responsibility to protect the public from pollution even as extreme weather risks grow. The speech highlights the administration’s sweeping reversal of federal climate policy, sets up likely courtroom battles over whether EPA can legally disclaim authority to regulate greenhouse gases, and underscores that Zeldin is aligning himself with organized climate‑skeptic networks as he is floated for promotion to attorney general.

Trump Environmental Policy Climate Regulation and EPA

📌 Key Facts

  • EPA Administrator Lee Zeldin delivered a keynote Wednesday at a Heartland Institute conference, telling climate skeptics to "celebrate vindication" after his agency repealed the 2009 endangerment finding.
  • The 2009 endangerment finding, adopted under Obama, concluded that carbon dioxide and other greenhouse gases endanger public health and welfare and served as the legal underpinning for nearly all federal climate rules under the Clean Air Act.
  • The Trump EPA has revoked that finding and now claims it lacks legal authority to regulate climate change, a position environmental groups denounce as disinformation and a dereliction of EPA’s duty to protect the public from pollution.
  • Heartland, which hosted Zeldin, describes itself as a free‑market think tank that seeks to "challenge the narrative" of a fossil‑fuel‑driven climate crisis and does not fully disclose its donors but has received oil and gas funding.
