SEAL BEACH, Calif.--(BUSINESS WIRE)--

In a press release issued Aug. 21, the Port of Los Angeles announced that Swift Transportation, Inc. and Knight Transportation, Inc., two major national motor carriers, will support the Port of Los Angeles Clean Truck Program as drayage concessionaires. Responding to the news, Clean Energy Fuels Corp. (Nasdaq:CLNE) has extended commendations to the two Phoenix-based trucking companies for their commitment to helping curtail harmful air pollutants in the Los Angeles region. The Swift and Knight organizations are expected to collectively deploy up to 2,000 new LNG and diesel trucks for Port Service that are compliant with 2007 EPA diesel emission standards.

Swift Transportation's Vice President, David Berry, said, "Swift Transportation is a leader in the trucking industry for sustainable green trucking. We support the clean air goals of the Ports of Los Angeles and Long Beach and recognize our responsibility to contribute to the effort. We are committed to using LNG trucks, the cleanest trucks available, as part of our strategy to reduce air pollution and greenhouse gases. We are working out the operational details of our program, but we intend to include LNG trucks as an integral part of our clean air solution."
