Clean Automotive Technology

Basic Information

The goal of the Clean Automotive Technology program is to research, evaluate, and develop advanced vehicle engine and drivetrain technologies that help increase fuel efficiency, reduce regulated criteria emissions such as nitrogen oxides (NOx) and particulate matter (PM), and cut greenhouse gas emissions. To achieve this outcome, the Clean Automotive Technology program focuses on developing technologies that are clean, efficient and cost-effective for both consumer and manufacturer. Through public-private partnerships called “Cooperative Research and Development Agreements,” or CRADAs, EPA works with the automotive industry to develop new technology that can be easily marketed worldwide. These partnerships have produced technological breakthroughs that are yielding real-world results.

The Clean Automotive Technology program focuses its research primarily on three areas: Engines, Hydraulic Hybrid Technology, and Alternative Fuels.

In addition to research and development, the Clean Automotive Technology program produces comprehensive Light-Duty Automotive Technology and Fuel Economy Trends Reports and provides technical and analytical support to the automotive industry. To learn more about CRADAs, visit our CRADAs page.
