Higher biodiesel blend offers cleaner fuel for Michigan farms

The Michigan Advanced Biofuels Coalition welcomes a major step toward cleaner farm operations as John Deere now approves B30 biodiesel blends for all Tier 4 Power Systems engines. This upgrade raises the approved level from B20 to B30, allowing 30 percent biodiesel mixed with 70 percent petroleum diesel. Farmers across Michigan can now power tractors, combines, and construction equipment with a higher renewable fuel blend that lowers harmful emissions.

John Deere also supports renewable diesel, approving RD100 for Tier 4 engines and blends up to B100 for Tier 3 and Tier 2 engines. Tier 4 engines feature advanced exhaust systems designed to cut particulate matter and nitrogen oxides. Using B30 takes emissions control further by reducing hydrocarbons and greenhouse gases, contributing to a healthier environment.

“Allowing use of B30 biodiesel fuel in John Deere equipment is good news for Michigan farmers and Michigan’s rural communities, especially as we head into the fall harvest season,” said Hanna Campbell, managing director of MiABC and market development director for the Michigan Soybean Committee. “Fueling tractors and combines with B30 leads to smoother engine operations and fewer carbon emissions for a cleaner, healthier environment.”

Biodiesel is produced from renewable resources such as soybean oil, used cooking oil, and other natural fats, many sourced within Michigan. This creates a strong market for soybean oil, adding value to crops grown by local farmers.

“Biodiesel is an ideal fuel choice for farm equipment because it is made from crops grown right here on our farms. We at the Michigan Soybean Committee are excited to see higher blends, like B30, approved for agricultural equipment and look forward to utilizing these blends during harvest this fall,” said Mark Senk, Owosso, Michigan, farmer and president of the Michigan Soybean Committee.

With Michigan using around one billion gallons of diesel each year, replacing petroleum diesel with higher biodiesel blends supports the economy by creating jobs in production, distribution, and sales while helping the state meet clean energy goals.

For over two decades, Dr. Mitloehner has been at the forefront of research on how animal agriculture affects our air and our climate. With deep expertise in emissions and volatile organic compounds, his work initially focused on air quality in regions like California’s Central Valley—home to both the nation’s richest agricultural output and some of its poorest air quality.

In recent years, methane has taken center stage in climate discourse—not just scientifically, but politically. Once a topic reserved for technical discussions about manure management and feed efficiency, it has become a flashpoint in debates over sustainability, regulation, and even the legitimacy of livestock farming itself.
