On February 13, 2026, the U.S. Environmental Protection Agency, led by Administrator Lee Zeldin, officially revoked emissions credits previously awarded to automakers for equipping vehicles with automatic start-stop ignition systems. These systems, which shut off the engine during brief stops to reduce emissions, have long drawn criticism from drivers who find them intrusive or annoying.
Zeldin acknowledged that sentiment in a post Tuesday on X (formerly Twitter), writing, “Countless Americans passionately despise the start/stop feature in cars,” and calling it an “absurd start-stop-start-stop concept.” The move delivers on a 2025 pledge he made to eliminate what he referred to as a “climate participation trophy.”
The rollback is part of a wider deregulatory push by the EPA under Zeldin’s leadership, which has included efforts to relax Corporate Average Fuel Economy (CAFE) standards that govern fleet-wide fuel efficiency for gasoline-powered vehicles.
Automakers largely backed the decision. Stellantis, parent company of Jeep, praised what it called a “rational, achievable approach on fuel economy standards that preserves customers’ freedom of choice.” Ford Motor Company echoed that sentiment, welcoming the effort to correct what it described as an “imbalance between current emissions standards and customer choice.”
General Motors referred questions to the Alliance for Automotive Innovation, an industry group representing major automakers. Its president, John Bozzella, noted that previous regulations had become “extremely challenging” in an environment of tepid electric vehicle demand. He emphasized the need to balance consumer preference with long-term emissions goals and global competitiveness.
By ending the emissions credits tied to start-stop systems, the EPA has removed a key regulatory incentive that encouraged their use. While the decision doesn’t ban start-stop tech outright, its decreased appeal to automakers could lead to reduced adoption across new models.
The move reshapes the emissions compliance landscape for major automakers like Ford, GM, and Stellantis, signaling a shift in federal policy that places greater weight on consumer satisfaction than on marginal emissions gains from unpopular features.
