The Clean Air Campaign and the region's transportation management associations are teaming up to get Mother Earth on track to better health. Be part of the One Ton Challenge!

The One Ton Challenge is a regional effort to encourage everyone to use a commute alternative. By not driving alone just one day per week, each metro Atlanta commuter can avoid emitting one ton of pollutants into the air over a course of one year.

Small changes can make a "ton" of difference. You do the math:

• 1 mile driven = 1 pound of air pollution¹ ²
• 40 miles driven (the average metro commuter’s daily round trip) = 40 pounds of pollution³
• 40 pounds of pollution x 52 days (one day a week for a year) = 2,080 pounds (or 1 ton) of pollution you can keep out of our air by clean commuting.
• Take the One Ton Challenge and commit to carpooling, riding transit, teleworking or any other commute alternative once a week for the next year. Join the hundreds of thousands of metro Atlantans making a difference to improve our air quality and traffic congestion.
