Effective today, April 1, biodiesel blend requirements in Illinois are increasing from B14 to B17, marking another step toward advancing cleaner fuel options.

The bipartisan B20 bill passed in 2022 raises the bar on biodiesel use by increasing the minimum biodiesel blend level eligible for tax exemption. Starting today, this means 17% of every gallon of biodiesel sold in Illinois between Apr. 1 and Nov. 30 will be derived largely from domestically produced, renewable vegetable oil, with soybeans being the top contributor.

Illinois Soybean Association (ISA) Chairman and Illinois soybean farmer Ron Kindred is proud to see the continuation of efforts that support our state’s farmers. “Increasing biodiesel blend rates is a win for farmers, consumers and the environment,” said Kindred. “Every step forward strengthens our energy security, drives demand for homegrown feedstocks, and supports rural economies.”

Next year, the minimum biodiesel blend levels eligible for a tax exemption will increase to the full 20 percent.
