You may have heard about California Air Resources Board’s (CARB) recent agreement with the truck and engine manufacturers. If not, here is a quick recap:
- The agreement aligns California’s NOx standards with those of the US Environmental Protection Agency (EPA), thereby, having one standard and one timeline.
- California compliant engines can be purchased outside of the state without requiring emission credit offsets.
- CARB agrees to provide no less than four years of lead time and at least three years of regulatory stability prior to imposing new regulations.
- Truck and engine manufacturers will not legally challenge or support other legal challenges to CARB’s regulations.
This agreement is specific to CARB’s Omnibus rules and does not alter CARB’s Advanced Clean Fleet (ACF) rules, which require zero-emission trucks at California’s marine and rail facilities as early as next year.
