CARB Guidance Clarifies Rules for Soy-Based Biofuels Under LCFS Program

The California Air Resources Board released updated implementation guidance for its Low Carbon Fuel Standard Sustainability Guardrails. The American Soybean Association welcomed the move, saying it provides regulatory certainty for U.S. soybean farmers and the renewable fuels industry. Key change: fuel producers can now use supply chain documentation and mass balance accounting instead of tracing soybeans back to individual fields. This simplifies compliance while maintaining LCFS sustainability standards. ASA President Scott Metzger said clear rules help farmers supply the renewable fuels market with confidence.
