• U.S. Chamber Comments on EPA's Phase 3 Greenhouse Gas Rulemaking Re: Heavy Duty Vehicles

June 13, 2023

The U.S. Chamber submitted the following comments on the U.S. Environmental Protection Agency’s (EPA) Notice of Proposed Rulemaking that would promulgate new greenhouse gas (GHG) standards for heavy-duty highway vehicles starting in model year (MY) 2028 through MY 2032 and revise the existing GHG standards for MY 2027.

The Chamber and its members are proud of their role as a collaborative partner with EPA and state regulators to develop emissions-reducing technologies and implement standards that have led to remarkable progress improving the nation’s air quality and addressing the climate challenge. This progress has occurred even as overall vehicle miles traveled have increased by nearly 50 percent since 1990.
