AIR QUALITY AND ETHANOL IN GASOLINE

Ethanol in gasoline can favorably impact mobile source emissions in five main air quality areas: these areas are fine particulate matter (e.g., PM2.5), carbon monoxide, toxics, ozone, and global warming. In this era of credit trading and with new data there is always a lot to do to integrate these air quality areas with respect to ethanol. For example, ethanol currently is the only compound that can be blended with gasoline to help reduce global warming; yet there is no program in place to offer any credit in this area. Below a brief overview the current situation in the other four air quality areas impacted by ethanol.
