EPA Issues Waiver To Allow Higher Ethanol Blends During Summer Driving Season

US regulators have decided to issue an emergency waiver allowing the sale of E15 fuel, which contains 15% ethanol, during summer months.
The waiver exempts E15 from anti-smog regulations that typically ban its use in summer.
The move aims to prevent fuel shortages and price spikes during high demand summer driving season.
While ethanol use increases pollution, research shows little difference in smog impacts between E15 and standard E10 blends.
The biofuels industry has pushed to expand E15, while oil companies have opposed the move.
