Calif. Group Files Suit Over Trucking Greenhouse-Gas Rules

A California group representing businesses has filed a federal lawsuit challenging the federal government’s greenhouse emissions regulations for medium- and heavy-duty trucks.

The Pacific Legal Foundation filed the suit Nov. 4 as a petition for review with the U.S. Court of Appeals for the District of Columbia Circuit.

PLF is challenging the joint rulemaking of the U.S. Environmental Protection Agency and the National Highway Transportation Authority that regulates greenhouse gas emissions from heavy duty vehicles and engines used for commercial or personal transportation.

It argues that EPA “must provide its Science Advisory Board with the opportunity to comment on these rules before they are finalized” and said EPA must comply with other federal regulations that “would subject the proposed regulations to rigorous scrutiny.”



The Obama administration unveiled the first-ever greenhouse-gas emissions for regulations for heavy trucks in August, which were widely praised by the trucking industry.

Several trucking original equipment manufacturers subsequently laid out their strategies to meet the new greenhouse gas regulations, detailing design innovations including weight reduction and improved aerodynamics.

PLF describes itself on its website as a “public interest legal organization that fights for limited government, property rights, individual rights and a balanced approach to environmental protection.”
