A new study from the University of California – Riverside shows that the E15 ethanol blend provides notable emissions reductions compared to California’s regular reformulated gasoline. The Renewable Fuels Association hailed the report as proof of the value of E15 for The Golden State, which has yet to allow the E15 blend to be used.
RFA President and CEO Geoff Cooper says, “This new study shows what we’ve been arguing all along–that E15 offers emissions benefits that would help meet environmental goals in California.”
According to the study, emissions of total hydrocarbons, non-methane hydrocarbons, and carbon monoxide all showed either marginally or statistically significant reductions for E15 compared to regular California gasoline. In addition, particulate matter and solid particle number emissions dropped substantially with E15, and E15 showed lifecycle greenhouse gas emissions savings when compared to E10. Nitrogen oxide emissions when using E15 showed marginal reductions in many cases, but the changes in Nitrogen oxide emissions were not statistically significant.
