Boosting Clean Fuel Use Statewide

By Andi Anderson

Iowa’s agriculture secretary submits formal comments to the California Air Resources Board, urging the state to move forward quickly while allowing E15 fuel sales. E15 is a cleaner-burning, lower-cost fuel blend already used successfully for more than a decade in many states. The comments emphasize that expanding access to this fuel would benefit drivers, strengthen biofuel markets, and support national energy goals.

In his statement, the secretary explains that consumer choice consistently drives E15 to use where it is available. He says, “Our experience in Iowa shows that when drivers are given the choice, they choose E15, and they choose it again and again. E15 is a cleaner-burning, more affordable fuel that works in most existing infrastructure, supports American-made energy, and delivers real savings for families.” He encourages California to look at Iowa’s results as a model for safe and effective E15 adoption.

Iowa leads the nation in renewable fuel production and has a large network of biorefineries that produce ethanol and biodiesel. This industry adds value to crops, supports thousands of jobs, and provides low-carbon fuel options for consumers. The secretary notes that Iowa’s long-term experience with E15 shows proven demand. Sales have grown more than sixfold in recent years, demonstrating that drivers quickly adopt the fuel once it becomes available.

E15 also provides financial benefits. The fuel is commonly priced at about 15 cents per gallon below regular unleaded, which saved Iowa drivers more than $38 million in one year. The secretary highlights that existing infrastructure is already widely compatible with E15, and that states like Iowa have introduced cost-share programs to support any necessary upgrades.

A statewide E15 access standard will take effect in Iowa in 2026, requiring most retailers to offer at least one pump. This policy reflects strong confidence in fuel safety and performance. The secretary encourages CARB to consider these results as California evaluates its implementation plan.
