CLEAR THE AIR
is an annual program to increase awareness of the problem caused by ground level ozone and provide viable solutions for the public to make a contribution by reducing harmful emissions.

EACH YEAR the Clear the Air campaign reminds you that riding CATS, joining a vanpool or carpool, riding your bike or walking to work is the best contribution you can make to help reduce ozone pollution.

What is Ground Level Ozone?

A highly reactive form of oxygen that is unhealthy to breathe and can damage trees and crops.  It is formed when nitrogen oxides react with volatile organic compounds in the air during very hot weather. 

Ground level ozone can come from a variety of sources.  But, the main culprit is the automobile. In the eight-county Charlotte region, nearly 50% of ozone-forming air pollution comes from on-road vehicles.
