American Clean Air Coalition

The Geoengineering fight has missed its target.

A coalition of researchers, legal advocates, and public health organizations filed a landmark federal Petition for Rulemaking with the U.S. Environmental Protection Agency, the first legal action of its kind to formally document, on the federal record, what is actually happening in America's skies and to demand that the government respond. 

Landmark Legal Action!

What action was taken and why?

For twenty years, Americans have looked up at the streaks crossing their skies and asked questions that have gone unanswered. On May 11, 2026, those questions were formally placed on the federal record for the first time in American history.

American Clean Air Coalition filed a landmark Petition for Rulemaking with the U.S. Environmental Protection Agency,  the most comprehensive scientific and legal document ever assembled on what is actually happening in America's atmosphere. Built on nearly two years of exhaustive research, peer-reviewed science, and the EPA's own contradictory documents, this Administrative Petition demands the agency fulfill its legal obligation under the Clean Air Act to address the unregulated atmospheric emissions of commercial aviation, emissions linked to changes in weather patterns, reductions in solar irradiance, contamination of agricultural soils and watersheds, and an estimated 74,300 premature deaths annually worldwide.
