This morning John Deere announced a major step forward in renewable fuel adoption: all Tier 4 engines are approved to use biodiesel blends up to 30%, commonly referred to as B30. A Tier 4 engine is a new diesel engine that meets the most stringent requirements set by the U.S. Environmental Protection Agency (EPA). These engines dramatically reduce pollutants such as particulate matter and nitrogen oxides.
Previously, John Deere recommended a maximum B20 blend in Tier 4 engines. All Tier 3 and lower tier engines are approved to use B100, or 100% biodiesel, offering even greater flexibility for farmers looking to use a fuel produced from the crops they grow.
“IRFA applauds John Deere’s approval of B30 in its most sophisticated engines,” said Iowa Renewable Fuels Executive Director Monte Shaw. “John Deere has always been a leader in promoting renewable fuels, including their biodiesel factory fill program and leading the way on engine approvals.”
This move is especially impactful in Iowa, where farmers benefit from the nation’s only B30 incentive program. These state-level credits help reduce fuel costs for end users, whether they are filling up at a retail station or having fuel delivered to their farming operation. Iowa fuel retailers receive a 10-cent-per-gallon tax credit for all B30 or higher blends sold.
“Beyond state incentives, IRFA offers an on-farm biodiesel credit that allows farmers to earn up to $500 for filling their tanks with biodiesel blends,” said IRFA Marketing Director Lisa Coffelt. “These programs make biodiesel more accessible and affordable for Iowa farmers, while supporting the state’s leadership in renewable energy.”
