California Air Resources Board v. Daimler Truck North America, LLC

California Air Resources Board (CARB) sued four heavy-duty on-highway truck and engine manufacturers in California Superior Court for allegedly breaching the terms of the Clean Truck Partnership, a 2023 agreement in which the defendant companies agreed to sell “clean vehicles” in California in consideration for CARB’s taking certain steps, including initiation of rulemaking proceedings. CARB sought specific performance of the contract or, alternatively, reliance damages, rescission of the contract, and damages for the defendants’ breach of the implied covenant of good faith and fair dealing. Several days after CARB filed this suit, the federal district court for the Eastern District of California granted the manufacturers’ motion for a preliminary injunction enjoining enforcement of the Clean Truck Partnership. In <a href="https://www.climatecasechart.com/collections/daimler-truck-north-america-llc-v-california-air-resources-board_876f">that case</a>, the manufacturers’ challenge to the Clean Truck Partnership is part of a broader lawsuit seeking to block California's enforcement of certain state vehicle emissions standards without a Clean Air Act preemption waiver from the U.S. Environmental Protection Agency.
