Illinois B20 Incentive Fully Takes Effect

By Andi Anderson

Illinois has fully implemented its B20 biodiesel incentive, marking a major step in clean energy policy.

The program encourages diesel fuel blended with at least 20% biodiesel giving retailers important tax relief. The law was designed to grow slowly starting with lower blends and rising each year until B20 became the standard.

This gradual approach helped fuel suppliers and users prepare equipment storage and transport systems.

The policy also includes a winter provision. From December through March, lower blends can still qualify for incentives ensuring reliable fuel performance during cold weather.

Lawmakers extended the program until 2030 providing certainty for farmers, fuel sellers and large diesel users planning future investments.

By exempting qualifying blends from state and local sales taxes, the incentive lowers diesel costs across Illinois. Savings are especially meaningful for trucking rail construction, farming and marine industries that buy fuel in large volumes.

Because Illinois fuel taxes are higher than many neighboring states, the incentive improves price competitiveness and keeps fuel purchases in state.

The policy supports several goals at once. It expands markets for soybean and corn oil strengthens farm income, reduces greenhouse gas emissions and cuts harmful particulate pollution.

Biodiesel burns cleaner than petroleum diesel which helps improve air quality especially in busy urban areas. Health groups support biodiesel uses because lower pollution levels reduce respiratory illness risks.

Illinois uses about one and a half billion gallons of diesel each year. At full B20 blending, the state can support significantly higher biodiesel production creating strong demand for soybeans.

Biodiesel demand adds meaningful value to each soybean and helps stabilize farm income during uncertain market conditions. Strong state demand also helped Illinois biodiesel use grow even when federal policies temporarily weakened national demand.

The law received bipartisan backing from urban suburban and rural leaders. Support came from farmers, retailers, fleet operators, and environmental groups.

Illinois experience shows that careful policy design can balance economic growth, environmental protection and public health while preparing the state for a more sustainable energy future.

The initiative demonstrates cooperation and planning for cleaner affordable fuels nationwide.
