Illinois Reaches Important B20 Milestone

Clean Fuels Alliance America applauded Illinois for moving to a B20 biodiesel blend requirement, a major milestone that strengthens the state’s leadership in expanding the use of cleaner, domestically-produced biofuels. Effective April 1, the minimum biodiesel blend required to qualify for Illinois’ state sales tax exemption increases from B17 to B20. That represents the final phase of landmark bipartisan legislation passed in 2022. The policy exempts qualifying biodiesel blends from the state’s 6.25 percent sales tax, creating a powerful market incentive to drive adoption. “Illinois has created a model that supports farmers, strengthens fuel markets, and improves air quality all at the same time,” said Jeff Earl, the director of state governmental affairs for Clean Fuels. The biodiesel industry generates $3.2 billion in annual economic activity in Illinois and supports 8,100 jobs across the state. “This is a win for rural communities, the environment, and energy security too,” Earl added.
