News Summary
Major truck manufacturers, including Daimler and PACCAR, have filed a lawsuit against California, challenging the enforcement of the Advanced Clean Trucks mandate. They argue the regulations create an ‘impossible’ operational situation, exacerbated by recent federal actions that invalidate EPA waivers. This legal conflict highlights the ongoing tensions between state efforts to implement stricter emissions standards and federal rollback policies, affecting the trucking industry’s compliance with environmental regulations.
California – Major truck manufacturers, including Daimler, PACCAR, Volvo Group North America, and International Motors, have formally filed a lawsuit in the U.S District Court for the Eastern District of California. The manufacturers are aiming to halt the enforcement of the California Advanced Clean Trucks (ACT) mandate, which they describe as creating an “impossible” operational situation. This lawsuit arises in the wake of recent federal actions that have invalidated the waiver from the Environmental Protection Agency (EPA) that allowed California’s emissions regulations to proceed.
The conflict stems from federal legislative and executive actions that have interfered with California’s ability to implement stricter emissions standards. The truck manufacturers argue that recent changes render compliance with the state’s emissions regulations increasingly challenging. Concurrently, California insists that federal actions to overturn EPA waivers are illegal and continues to demand compliance with the California Air Resources Board (CARB) standards.
To navigate the emerging disparities between state and federal regulations, the Engine Manufacturers Association (EMA) had agreed in 2023 to a framework known as the Clean Truck Partnership (CTP). This partnership was intended to facilitate compliance with the ACT while aligning California’s mandates with federal regulations. However, developments such as a letter sent by the Department of Justice (DOJ) on August 7 directed Daimler and other manufacturers to cease complying with the CTP, raising significant concerns over legal obligations.
In response to the manufacturers’ lawsuit, CARB has also initiated its own litigation against the federal government, maintaining that EPA waivers are not subject to disapproval under the Congressional Review Act. The truck manufacturers, in their suit, have requested clear guidelines from CARB regarding their obligations under the CTP, asserting that conflicting federal laws preempt these obligations.
Recent actions by CARB have imposed additional requirements on manufacturers. A Manufacturers Advisory Correspondence issued on May 23 prompted engine makers to follow CARB’s preempted standards in order to ensure lawful sales in California. Furthermore, the executive order from California Governor Gavin Newsom has reportedly warned manufacturers that unwelcome regulatory treatment could ensue if they fail to adhere to the ACT mandates.
Despite CARB’s adjustments to the ACT intended to offer some flexibility, the agency also highlighted commitments linked to the CTP, presenting an ongoing struggle for the manufacturers. The lawsuit points to an environment where compliance with the ACT is now more complicated, particularly following the elimination of the Advanced Clean Fleets rule, which previously mandated fleets to procure a designated percentage of zero-emission vehicles.
In addition to seeking clarification on emissions rules and obligations for the 2026 model year, the truck manufacturers have also cited potential violations of the Clean Air Act’s preemption provisions by California. They challenge the constitutional validity of a particular provision in the CTP that limits manufacturers’ ability to contest CARB’s methodologies and decisions. The manufacturers seek injunctive relief to prevent CARB from enforcing the ACT and other related regulations.
While CARB has declined to comment on the pending lawsuit, the Clean Freight Coalition has voiced support for the truck manufacturers, describing the lawsuit as necessary. Conversely, environmental critics have argued that the manufacturers’ claims contradict the original intent of the Clean Truck Partnership, which aimed to ease transitions through regulatory changes.
This lawsuit underscores a significant clash between California’s ambitious climate strategies and federal regulatory rollbacks. As truck manufacturers navigate these conflicting demands, the implications for the industry’s operational viability and environmental policy remain critically important.
