Ethanol — A Clean Air Choice

Clean Air Choice logo

Using ethanol reduces harmful vehicle and greenhouse gas emissions, allowing us to all breathe a little easier.

That’s why higher blends of ethanol are recognized as a Clean Air Choice of the American Lung Association.

Reduces emissions
Adding ethanol to gasoline reduces tailpipe emissions of pollutants such as carbon monoxide, carcinogenic air toxics like benzene, and fine particulate matter which can cause asthma and other serious health effects.

Lowers Greenhouse Gases
According to new analyses conducted for the U.S. Department of Agriculture, corn ethanol reduces greenhouse gas (GHG) emissions by 40-45% compared to gasoline—even when hypothetical land use change emissions are included. The use of ethanol in gasoline in 2017 reduced CO2-equivalent GHG emissions from transportation by 53.5 million metric tons— equivalent to removing 11.4 million cars from the road for an entire year.
