UAI: Removing ethanol from gasoline increases toxic emissions

By Urban Air Initiative | July 29, 2015

Many gas stations are promoting E0, or gasoline with zero percent ethanol. It not only costs more than regular gasoline that contains 10 percent ethanol, new data shows it also burns dirtier in your engine which then puts more toxic emissions into the air.

Urban Air Initiative tested every E0 in Wichita, Kansas, and compared them to regular gasoline that contains 10 percent ethanol. The testing found toxic aromatics such as benzene and toluene were about 45 percent higher with E0. Benzene and toluene, which are known carcinogens, are added by oil refineries to boost octane in vehicles. However, these toxins create harmful emissions that cause air pollution which impact public health.

UAI knows this isn't just a problem in Kansas. A recent study by the group Clean Fuels Omaha also found higher toxic emissions in Omaha, Nebraska with E0 compared to regular gasoline or E10.

The data is clear; adding ethanol to gasoline reduces toxic emissions, improves air quality and our health. For more information, please visit and
