CARB releases results of multi-year E15 study; multiple air quality benefits with slight reduction in fuel economy

Green Car Congress

JULY 18, 2022

The California Air Resources Board (CARB) has released the results of a multiyear study evaluating exhaust emissions from the use of California Reformulated Gasoline (CaRFG) that contains 15 volume percent ethanol (E15). California currently limits the ethanol content of gasoline to 10 percent.

Traffic contributes more to NO x emissions in Europe than previously thought, according to a new study by a team at the University of Innsbruck. It has been a challenge to determine how much each polluter contributes to the emission output. The majority of the emissions is caused by diesel cars. —Thomas Karl.

The alternative-fuel car evolved to reduce exhaust emissions and other problems derived from burning fossil fuels. The PHEV (Plug-in Hybrid Electric Vehicle), a subset of the electric car, combines a primary electric motor with a much smaller back-up engine fueled with a hydrocarbon/biofuel mix. It is much more than that.
