Washington — Aaron Szabo, the EPA’s assistant administrator for the Office of Air and Radiation, resigned effective Friday after guiding the agency through the Trump administration’s most extensive climate‑policy reversals. The agency announced his departure on Tuesday, noting that Szabo had been asked to stay beyond his originally planned July exit.
Key achievements under Szabo
During his tenure, Szabo oversaw programs that regulate air pollution, vehicle emissions, and the blending of gasoline with renewable fuels—core components of the Clean Air Act. Under his leadership, the EPA moved to repeal its 2009 finding that greenhouse gases endanger public health and welfare, a step that could dramatically limit the agency’s authority to address climate‑related pollution.
The office also worked on rolling back emissions rules for power plants, automobiles, and the oil and gas sector, actions the agency described as the “single largest deregulatory action in U.S. history.” The EPA estimated that the cost savings associated with these changes exceed $1.6 trillion.
Agency response
In an email to Reuters, the EPA thanked Szabo for his “tremendous work” advancing President Donald Trump’s agenda. The statement highlighted the administration’s commitment to reducing regulatory burdens and fostering economic growth by eliminating what it called unnecessary federal overreach.
Succession plan
The agency named Justin Schwab, a senior adviser to EPA Administrator Lee Zeldin, as Szabo’s nominee to fill the vacancy. Both Szabo and Schwab declined immediate comment on the transition.
Context and implications
The departure comes as the Trump administration continues to prioritize deregulation across multiple sectors. Supporters argue that cutting red tape spurs innovation, lowers energy costs for families, and respects the Constitution’s limits on federal power. Critics, however, warn that weakening emissions standards could jeopardize public health and undermine long‑term environmental stewardship.
Regardless of the debate, Szabo’s exit marks the end of a pivotal chapter in the EPA’s recent history, one defined by a clear shift toward deregulation and a focus on reducing compliance costs for industry.
