Low Carbon Fuel Standard (LCFS)

Washington’s Clean Fuels Program (Program) requires a reduction in the overall carbon intensity of transportation fuels used in the state by 20% below 2017 levels by 2034. The Program requires transportation fuel producers and suppliers to meet specified average carbon intensity requirements for fuel. The Program’s regulated fuels include gasoline, diesel, gasoline mixed with at least 10% corn-derived ethanol, biomass-based diesel, propane, and hydrogen. Producers of low carbon fuels, such as electricity and alternative jet fuel, may participate, but are not required to register for the Program. Aviation fuel, marine fuel, railroad fuel, and offroad fuel used for agriculture, logging, mining, and other activities are exempt and will not generate deficits. The Program allows producers and importers to generate, acquire, transfer, bank, borrow, and trade credits. Fuel producers and importers regulated under the LCFS must meet quarterly and annual reporting requirements.
