Congress Eliminates Corporate Average Fuel Economy (CAFE) Penalties for Passenger Cars and Light Trucks

In one of its many changes, the One Big Beautiful Bill Act, enacted on July 4, 2025, eliminated civil penalties for noncompliance with federal fuel economy standards.  Specifically, Section 40006 of the Act amends the language of the Corporate Average Fuel Economy (CAFE) statute to reset the maximum civil penalty to $0.00.  Although the statute and its implementing regulations otherwise remain in place, this amendment removes any civil penalties for producing passenger cars and light trucks that do not meet fuel economy requirements.

Supreme Court Issues Split Rulings on Clean Air Act Venue Disputes

On June 18, 2025, the U.S. Supreme Court issued decisions in two significant Clean Air Act cases — EPA v. Calumet Shreveport Refining and Oklahoma v. EPA — clarifying the appropriate venue for legal challenges to certain final EPA actions. In Calumet, the Court held that EPA’s universal denials of small-refinery-exemption (SRE) petitions under the Renewable Fuel Standard program were “based on a determination of nationwide scope or effect,” and thus challenges may only be brought in the D.C. Circuit Court of Appeals. By contrast, the Court in Oklahoma held that challenges to EPA’s disapproval of State Implementation Plans (SIPs) belong in the applicable regional circuit courts because the agency’s determinations were based on facts and rationales unique to each state. Although some gray areas remain, the twin decisions put several long-standing venue issues to rest and should encourage quicker resolution of Clean Air Act regulatory challenges.
