Bill Summary · SF 2387

Legislative bill overview

SF 2387 requires that passenger vehicles rented or leased by the State of Iowa be compatible with biodiesel blended fuel at B-20 concentration or higher (meaning 20% biodiesel mixed with 80% petroleum diesel). The bill includes provisions specifying how and when these compatibility requirements apply to state vehicle fleets.

Why is this important

Iowa is a major biodiesel producer, and mandating state fleet compatibility with higher biodiesel blends creates reliable demand for in-state fuel production, supporting the agricultural and renewable fuel industries. This also affects state procurement decisions and fuel costs, while advancing renewable fuel adoption at the government level.

Potential points of contention

  • Cost implications: Requiring B-20 or higher compatibility may increase vehicle purchase prices or limit supplier options, potentially raising state fleet acquisition costs
  • Vehicle manufacturer constraints: Not all vehicle models are certified for B-20+ use; this could restrict the state's purchasing flexibility or require retrofitting existing vehicles
  • Fuel availability and infrastructure: B-20 availability at state fueling stations may be limited, requiring infrastructure investment or creating logistical challenges for some state agencies
