Thomas A. Lorenzen
Crowell & Moring LLP
Tom Lorenzen is Co-chair of Crowell & Moring's Environment & Natural Resources Practice Group and is one of just four attorneys in the U.S. ranked as Band 1 in climate change law by Chambers and Partners. With over a decade's experience at the Department of Justice as the Assistant Section Chief responsible for supervising the defense of all Environmental Protection Agency regulations, Tom has a deep understanding of both the federal rulemaking process and the limits of EPA's regulatory authority.
Tom is also known for his extensive appellate and administrative law experience, which he brings to bear when his clients choose to challenge the EPA's and other agencies' regulations in court, and increasingly when they seek to defend regulations that they determine present opportunities for their businesses. Tom was the principal author of electric utility industry's amicus brief in West Virginia v. EPA, in which the industry successfully urged the Supreme Court to preserve EPA's authority to regulate GHG emissions under the Clean Air Act in order to stave off the reemergence of federal tort claims against GHG emitters.
