Overview
- The EPA issued an emergency waiver allowing the nationwide sale of E15 gasoline during the summer months, effective May 1, 2025.
- E15, a fuel blend with 15% ethanol, is typically restricted in summer due to concerns about smog formation in warmer weather.
- This move is expected to increase fuel supply, reduce pump prices, and benefit biofuel producers and corn farmers by expanding demand for ethanol.
- The waiver follows similar temporary measures under the Biden administration from 2022 to 2024 and coincides with a new Midwest year-round E15 policy implemented earlier this month.
- Environmental concerns persist, with critics warning of potential air quality impacts, while proponents argue these claims are overstated.
