Cleaner Biofuels Act of 2024

The Cleaner Biofuels Act of 2024 revises the Clean Air Act to allow corn-based ethanol to count as an advanced biofuel when it achieves at least 50% lifecycle greenhouse gas emissions reductions (compared to baseline), and creates a new system for generating supplemental Renewable Identification Numbers (RINs). Producers of qualifying corn ethanol earn 30%-40% additional RINs for 50%-60% emissions reductions, while other advanced biofuels earn 50%-100% more RINs for 70%-100% reductions. The Environmental Protection Agency (EPA) must issue rules within one year to verify emissions reductions from farming practices, add supplemental RINs to the Renewable Fuel Program, and adjust annual RIN requirements to maintain program goals. This directly affects biofuel producers, the EPA, and the Renewable Fuel Program by expanding RIN eligibility and requiring new verification processes.
