Overview

• EPA Administrator Lee Zeldin has proposed rescinding the 2009 finding that greenhouse gases endanger public health, which underpins federal vehicle and power‑plant emissions standards.
• Data for Progress reports that 86% of likely voters say greenhouse‑gas emissions should be regulated, with support spanning Democrats, Independents and Republicans.
• Medical and environmental organizations, including the American Lung Association, the American Public Health Association and the American Thoracic Society, oppose the proposal and warn of increased health harms.
• The EPA attributes $2 trillion in economic benefits to the Clean Air Act by 2020 alongside major reductions in pollution‑related deaths and illnesses, according to figures cited in recent commentary.
• The proposal is in a public comment period, with one opinion column urging submissions by Sept. 15 via the EPA docket email.
