• U.S. Chamber Comments on EPA's Proposed Rule, "Control of Air Pollution from New Motor Vehicles: Heavy-Duty Engine Standards"

May 16, 2022

Dear Administrator Regan: The U.S. Chamber of Commerce appreciates the opportunity to comment on the U.S. Environmental Protection Agency’s (EPA) Notice of Proposed Rulemaking (“the Proposal”) to modify nitrogen oxide (NOx) and greenhouse gas (GHG) emissions standards for highway medium- and heavy-duty engines and vehicles.

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 cleaning up the nation’s air. Efforts made to reduce NOx from all sectors of the economy, including heavy-duty highway engines, have been a major factor driving this progress.
