He provides counsel to industry leaders in the transportation, energy, technology, and consumer sectors on emerging environmental and clean energy issues.

Mr. Guzy co-chairs the firm’s Energy Industry Group.

He was a member of the Administrator’s senior policy team, setting regulatory, legislative, and communications strategy. He led efforts to design regulatory approaches to protect children’s environmental health, develop and defend new air quality and motor vehicle standards, defend EPA from Congressional oversight investigations, and protect iconic ecosystems such as the Everglades and Yellowstone National Park. He also authored climate change opinions that were later ratified by the U.S. Supreme Court in its landmark decision finding that greenhouse gases are pollutants under federal law.
