What changed

This document contains a letter submitted to the National Highway Traffic Safety Administration (NHTSA) from Representative Doris Matsui and other members of Congress, expressing opposition to any proposed rollback or weakening of Corporate Average Fuel Economy (CAFE) standards. The letter argues that maintaining or strengthening these standards is crucial for national energy security, environmental protection, and consumer savings on fuel.

While this is a letter of comment and not a proposed rule itself, it signals significant congressional concern regarding potential changes to fuel efficiency regulations. Regulated entities, particularly in the automotive sector, should be aware of this opposition and the arguments presented, as it may influence future regulatory actions or enforcement priorities by NHTSA. No specific compliance actions are required based on this letter alone, but it indicates a potential area of regulatory focus and advocacy.

What to do next

  1. Review the arguments presented in the letter regarding CAFE standards.
  2. Monitor NHTSA's official communications for any proposed changes to CAFE standards.
