Clean Energy, Leading U.S. Natural Gas Fuel Supplier, Pledges to Support San Pedro Bay Ports' New Air Pollution Reduction Plan

SEAL BEACH, Calif.--(BUSINESS WIRE)--June 30, 2006--

Will Build Natural Gas Fueling Stations Convenient to Port Truckers, Offer Special Financing to Help Fleets and Individual Owner-Operators Acquire New Natural Gas Trucks

“Natural gas is one of the best ways to reduce air pollution because it burns far cleaner than diesel, reducing harmful tailpipe emissions significantly”

Clean Energy, leading U.S. supplier of liquefied and compressed natural gas (LNG and CNG) vehicle fuel and related services, has announced full support for the goals of the new San Pedro Bay Ports Clean Air Action Plan. The company has pledged to build three new natural gas fueling stations that will be conveniently accessible to cargo container truckers serving the Port of Los Angeles and the Port of Long Beach. In addition, Clean Energy will offer special financing packages to fleets and independent owner-operators to help them acquire new natural gas powered trucks.

"Natural gas is one of the best ways to reduce air pollution because it burns far cleaner than diesel, reducing harmful tailpipe emissions significantly," said Andrew J. Littlefair, Clean Energy CEO. "We applaud the combined Ports' action in confronting this significant pollution problem head-on. Clean Energy will work closely with the Ports and related parties in the coming period to help ensure that the plan be as effective as possible and result in a truly healthier environment for the people of the Ports and all of Southern California."

The goal of the plan is to reduce public health risk from toxic air contaminants to acceptable levels. One of the key components is modernizing the truck fleet with new trucks that meet certain standards for particulate matter (PM) and nitrogen oxide (NOx) emissions. The plan estimates that over 16,000 trucks will be involved. The newest generation of natural gas trucks, which are scheduled to go into service beginning in 2007 when the Ports' action plan begins, will already meet the EPA's most stringent emissions standards.

Clean Energy's finance program, combined with federal, state, regional and Ports' incentives, is expected to make affordable natural gas trucks available to fleets and independent owner-operators now driving older, heavily polluting vehicles.
