A U.S. federal court ruled that the Department of Energy violated the law when it formed a climate science advisory group comprised of five climate change skeptics, without public meetings or notice. The Environmental Defense Fund and Union of Concerned Scientists had sued the DOE, arguing the group's report was used to inform the EPA's rulemaking process to repeal the 'endangerment finding', the legal foundation for its climate change regulations.

Why it matters

This ruling could undermine the legal basis for the EPA's plan to repeal the 'endangerment finding', a key regulation that underpins the agency's authority to address climate change. The court found the DOE violated federal law in how it convened the climate skeptic group, raising questions about the legitimacy of its report and the EPA's use of it.

The details

The U.S. District Court for the District of Massachusetts issued a judgment stating the Trump administration's creation of the Climate Working Group violated the law governing federal advisory committees. The environmental groups argued the DOE did not hold public meetings or provide notice when forming the group, which then produced a report used by the EPA in its rulemaking process.

  • The Climate Working Group report was released on July 29, 2026, the same day the EPA formally proposed a rule to rescind the 'endangerment finding'.
  • The environmental groups sued the DOE over the Climate Working Group in 2025.

What they’re saying

“The federal court's ruling is absolutely clear – the Trump Administration violated federal law by secretly convening a group tasked with developing a dangerously slanted report to use as the basis for attacking the Endangerment Finding.”

— Erin Murphy, Senior Attorney, Environmental Defense Fund (ksgf.com)

“The groups have sought to silence scientists who have merely pointed out – as the Climate Working Group did in its report – that climate science is far from settled.”

— Ben Dietderich, Department of Energy Spokesperson (ksgf.com)

What’s next

The EPA's final rule to repeal the 'endangerment finding' remains under review at the White House, and the court's ruling could jeopardize the legal basis for that action.

The takeaway

This case highlights the ongoing political battles over climate change policy, with the courts now intervening to uphold the proper procedures for federal advisory committees. The ruling casts doubt on the legitimacy of the DOE's climate skeptic report and its potential use by the EPA, underscoring the importance of scientific integrity in policymaking.
