Suppliers and producers of regulated fuels (e.g., gasoline, diesel, ethanol and blends, biomass-based diesel and blends, and natural gas) are mandated to participate in the program. These fuels generate deficits in proportion to how much higher their CI is than the CI reduction target in a given compliance year.Exempt fuels such as aviation fuel, marine fuel, railroad fuel and off-road fuel (for agriculture, mining, logging, or other activities) do not generate deficits.
