Chairmen Guthrie and Palmer Announce Hearing on the Modernization of the Clean Air Act’s Mobile Source Requirements

WASHINGTON, D.C. – Today, Congressman Brett Guthrie (KY-02), Chairman of the House Committee on Energy and Commerce, and Congressman Gary Palmer (AL-06), Chairman of the Subcommittee on Environment, announced a hearing titled Rules of the Road: Examining Legislation to Modernize the Clean Air Act's Mobile Source Requirements.

“The Clean Air Act regulates not just the cars we drive but also the trucks and trains that transport and deliver food, consumer products, and even the energy needed for our daily lives. Actions by the Biden-Harris Administration and states like California have taken away consumer choices and driven up costs to advance a radical environmental agenda instead of focusing on responsible environmental policies that complement lower costs and innovation,” said Chairmen Guthrie and Palmer. “This hearing will provide the opportunity to examine how burdensome regulations that have led to higher costs and unnecessary red tape can be addressed while continuing to protect the air we breathe.”
