Heavy-Duty GHG Vehicle Program
The Heavy-Duty Greenhouse Gas Section was created in December 2019 to implement the newly adopted California Phase 2 GHG Emissions Standards, which set forth new GHG standards and certification requirements for medium and heavy - duty vocational vehicles and tractors as well as trailers. This Section conducts evaluations and processes the associated certifications to approve for sale vehicles that comply with the Heavy-Duty GHG requirements.
