An Act to establish a clean fuel standard

HD 2311 establishes a standard requiring transportation fuel providers (such as refiners, blenders, and retailers) to reduce the carbon emissions of transportation fuels by 80% from 1990 levels by 2050. It creates a credit system where providers using low-carbon fuels earn tradable credits to offset higher-emission fuels, measured across the full fuel lifecycle. The law also requires public entities earning credits to invest a portion in clean energy and accessible transportation projects for disadvantaged communities. The standard excludes aviation, rail, military, and waterborne fuels due to federal preemption.
