On March 15, 2024, the California Department of Justice (DOJ) and the California Air Resources Board (CARB) announced a significant settlement with engine manufacturer Cummins Inc. The settlement, totaling $46 million, aims to resolve claims of violations related to California engine emission control and certification requirements.

According to the announcement, Cummins had made undisclosed changes to around 120,000 engines in California after CARB had certified them for sale. Additionally, approximately 2,000 Cummins engines were found to have undisclosed auxiliary emission control devices that altered the emissions control system, leading to emissions exceeding regulatory limits.

California Attorney General Rob Bonta emphasized the importance of holding accountable those who compromise public health and safety, stating, "Today’s settlement makes clear that the DOJ will relentlessly continue its efforts to hold accountable those who seek to profit at the expense of people’s health and safety."

Dr. Steven Cliff, CARB’s Executive Officer, highlighted the significance of collaboration between regulatory bodies and manufacturers in ensuring air quality laws are upheld and violations are promptly addressed. He stated, "CARB’s rigorous, state-of-the-art enforcement efforts ensure that air quality laws are followed."

The violations came to light through a combination of CARB’s investigative methods and Cummins' commitment to reporting emissions-related concerns. Cummins has agreed to conduct an emissions recall on the affected engines at no cost to owners and has the option to offset a portion of the penalty with a project aimed at enhancing heavy-duty zero-emissions charging infrastructure in California.

The settlement also includes a $4 million agreement with the California Attorney General’s Office for unfair business practices and public nuisance claims, with injunctive relief to prevent future violations by Cummins.

This settlement represents a significant step in CARB's efforts to enforce environmental regulations and underscores the importance of compliance with emission control requirements to safeguard public health and the environment.
