Transportation and Air Quality


EPA's Office of Transportation and Air Quality (OTAQ) partnerships aim to achieve measurable environmental results in a cost-effective and beneficial way without the need for regulation.  These programs can reduce pollution and improve air quality by means of forming partnerships with small and large businesses, citizen groups, industry, manufacturers, trade associations, and state and local governments.

Partners in these programs work together to improve environmental performance and in return receive such benefits as cost savings, public recognition, and the satisfaction of knowing that they are helping to clean the air.  The results from these programs are impressive.  Learn more about our programs and see how you can participate.


A collaborative program between EPA and the freight industry that will increase the energy efficiency and energy security of our country while significantly reducing air pollution and greenhouse gases. The Partnership creates strong market-based incentives that challenge companies shipping products and the truck and rail companies delivering these products, to improve the environmental performance of their freight operations. SmartWay Transport partners improve their energy efficiency, save money, reduce greenhouse gas emissions and improve air quality.
