Summary of Oct 2023 CARB workshop for Tier 5 non-road standards
In a workshop held on Oct 30th – 31st, 2023, California’s Air Resourced Board (CARB) discussed proposed changes to the tailpipe emission standards for non-road machinery (construction, agricultural, gen-sets, etc.). Here is a summary of some of the key elements of the proposed changes.
Note: This was a workshop to discuss changes and get stakeholder feedback, so this is not a final proposal and expect more changes to come.
