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.

A new study quantifying emissions from a fleet of gasoline direct injection (GDI) engines and port fuel injection (PFI) engines finds that the measured decrease in CO 2 emissions from GDIs is much greater than the potential climate forcing associated with higher black carbon emissions from GDI engines.

Using statistical methods, the scientists infer emissions from these data within a radius of about one kilometer of the measurement location. Generally, different combustion and exhaust treatment characteristics result in significantly higher NO x /CO 2 emission ratios for diesel powered cars than for gasoline.
