California AG Reached Settlement with Engine Manufacturer for Violating Emissions Regulations

MARCH 15, 2024

California Attorney General Rob Bonta announced that his office, and the California Department of Justice (DOJ) and the California Air Resources Board (CARB), reached two separate settlements with Cummins Inc., an engine manufacturing company, to resolve allegations that the company violated emission control requirements. According to the settlement, the company made changes to 120,000 engines after they had already been certified—including by adding defeat devices to around 2,000 engines—so that the engines could exceed emissions standards without being detected. Under the settlement with DOJ and CARB, Cummins was required to pay $46 million, $9.8 of which will be used to help mitigate the excessive nitrogen oxide emissions created by the engines. Under the settlement with the California AGO, Cummins will pay $4 million “for unfair business practices and public nuisance claims and secured injunctive relief prohibiting Cummins from engaging in similar violations in the future.”
