EPA's SmartWay Technology program develops test protocols, reviews strategies and verifies the performance of vehicles, technologies and equipment that have the potential to reduce greenhouse gases and other air pollutants from freight transport. The program establishes credible performance criteria and reviews test data to ensure that vehicles, equipment and technologies will help fleets improve their efficiency and reduce emissions.

EPA has evaluated the fuel saving benefits of various devices through grants, cooperative agreements, emissions and fuel economy testing, demonstration projects and technical literature review. As a result, EPA has determined the following types of technologies provide fuel saving and/or emission reducing benefits when used properly in their designed applications:

Within each of these categories, EPA has verified specific products. EPA continues to evaluate and verify new products. Although EPA has verified the fuel saving and/or emission reducing benefits of the listed products, EPA does not endorse the purchase of products or services from any specific vendor. EPA urges you to compare products, services, and prices before making your purchase. EPA cannot confer verification on any product not listed.
