The Air Resources Board proposed amendments to regulations governing low carbon fuel standards. The amendments would require a 30% reduction in fuel carbon intensity (CI) by 2030 and a 90% reduction by 2045 from a 2010 baseline, implement a one-time, 5% reduction in the CI benchmark in 2025, eliminate the current exemption for intrastate fossil jet fuel starting in 2028, expand zero emission vehicle infrastructure crediting to the medium- and heavy-duty vehicle sector, and streamline quantification methods and analysis tools for low-carbon fuel production. A hearing will be held March 21, 2024. Comments are due February 20, 2024. See https://oal.ca.gov/wp-content/uploads/sites/166/2024/01/2024-Notice-Register-No.-1-Z-January-5-2024.pdf (pp. 14-25).
