Welcome to the Atlanta Heavy-Duty Vehicle and Equipment Inventory and Emissions Study homepage!  The purpose of this study is to provide state and local policymakers with an accurate assessment of the air pollution emissions generated by heavy-duty vehicles and equipment operating in the Atlanta area, and to recommend cost-effective ways to reduce those emissions.  Heavy-duty vehicles and equipment include trucks and buses, as well as, non-road equipment such as bulldozers and locomotives.  Heavy-duty vehicles and equipment contribute to the summertime smog problem in Atlanta. 

Partnering together, the Georgia Regional Transportation Authority, the Georgia Department of Natural Resources Environmental Protection Division, and the Georgia Department of Transportation have commissioned the Georgia Institute of Technology and Environ Corporation to conduct this study.  Georgia Tech and Environ are collecting a detailed inventory of the heavy-duty vehicles and equipment operating in the 21-county Atlanta area, which they will use to evaluate the cost-effectiveness of potential strategies to reduce heavy-duty emissions.  Examples of potential strategies include retrofitting older heavy-duty diesel equipment with oxidation catalysts and using ultra-low sulfur diesel fuel.  The Atlanta Regional Commission and the State Road and Tollway Authority of Georgia are providing additional technical guidance to the study.
