A new study from the University of California shows E-15 provides more emissions reductions compared to other blends of gasoline on the market.

A new study shows E-15 provides more emissions reductions compared to other blends of gasoline on the market.

The study from the University of California found E-15 decreased emissions more than California’s reformulated gasoline. Right now, E-15 is not allowed to be sold in The Golden State.

Researchers also found particulate matter emissions dropped significantly with the blend.

Jeff Cooper with the Renewable Fuels Association says the study proves what his group has been arguing all along--and that E-15 would help meet environmental goals in California.
