California Air Resources Board

What you need to know: The California Air Resources Board settled with Volvo Group North America, LLC for nearly $197 million for alleged violations of emissions and certification requirements. The state will receive almost $18 million in penalties and $71 million towards mitigation of the air quality harms caused by the violations, with an additional $108 million going towards emission reduction projects across California.  

SACRAMENTO – The California Air Resources Board (CARB) today announced a settlement with Swedish engine and vehicle manufacturer Volvo Group North America, LLC (Volvo) for nearly $197 million dollars for undisclosed auxiliary emission control devices (AECD) that violated the state’s emissions and certification requirements. The state will receive $17.5 million in penalties and costs and $71 million to mitigate the air quality harms caused by the violations. Volvo also is committing $108 million toward emission reduction projects in California. 

The case involves approximately 10,000 Volvo model year 2010 through 2016 diesel engines used in heavy-duty trucks throughout California. CARB alleged these engines used AECDs that were not adequately disclosed during the required emissions certification process. Failure to report AECDs completely and accurately to CARB is a major violation of California’s heavy-duty engine regulations.  

“This case underscores why CARB's compliance testing and strong enforcement are essential to protecting the state's air quality and public health. Our responsibility goes beyond adopting regulations — we are committed to upholding them by identifying violations and holding companies accountable for meeting emissions standards,” said CARB Chair Lauren Sanchez.  

These Volvo engines emitted more smog-forming nitrogen oxides (NOx) than allowed by the emission standard. NOx is a potent air pollutant that contributes to the formation of ozone and particulate matter. It is known to aggravate health problems such as asthma and cardio-pulmonary disease. Nearly 18 million Californians live in areas with unhealthy air quality, which leads to significant public health costs. The emission reduction projects to be funded by Volvo will focus on reducing air pollution and the related health impacts. 

Volvo was cooperative throughout CARB’s investigation and agreed to offer a recall repair and extended warranty to address the AECDs. The recall will apply to Volvo’s model year 2014 through 2016 diesel engines at issue in this case.
