November 11, 2026. Aemetis, Inc., a renewable natural gas and biofuels company, announced that the California Air Resources Board (CARB) has approved provisional pathways under the Low Carbon Fuel Standard (LCFS) for six dairy digesters built and operated by Aemetis Biogas LLC, a subsidiary of the company. The pathway approvals are effective as of October 1, 2026. The average carbon intensity for the six approved pathways is negative 351.
“In addition to the seven dairy pathways that were approved in June 2025, the approval of these six pathways significantly increases the number of LCFS credits generated by the Aemetis Biogas Central Digester Project,” said Eric McAfee, Chairman and CEO of Aemetis. “Using the Tier 1 filing process, two additional dairy digesters that were recently constructed will be eligible to receive LCFS pathway approvals next year. With large reductions in the number of excess banked LCFS credits expected each quarter for many years, we expect the current $90 market price for LCFS credits to continue to increase.”
The Aemetis Biogas Central Digester Project near Modesto, California, currently includes 14 digesters supplied by waste from 17 dairies. The biogas is transported by 36 miles of pipeline to a central renewable natural gas production facility in Keyes, California that is interconnected to the PG&E utility pipeline.
