Clean Energy Signs Fueling Contract for City of Las Vegas Transit Fleet

– Agreement Marks First Vehicle Fueling Operations in Nevada for Clean Energy –

Seal Beach, Calif. (April 24, 2008) - Clean Energy Fuels Corp. (Nasdaq:CLNE) has been awarded the contract to supply compressed natural gas (CNG) fuel and provide operations and maintenance for two transit fueling stations in Las Vegas, Nevada by the Regional Transportation Commission of Southern Nevada (RTC). The RTC is both the transit authority and the transportation planning agency for Southern Nevada.

The two RTC stations currently fuel more than 50 CNG buses and paratransit vans serving the greater Las Vegas region. A total of 45 new CNG buses are on order for delivery in 2009.

"Las Vegas is an exceptional market for natural gas vehicles -- air quality is compromised by diesel emissions and the expanding CNG bus fleet can help improve the air quality measurably," said Andrew J. Littlefair, Clean Energy President and Chief Executive Officer. "The favorable cost differential between natural gas and diesel fuels adds even more value for the RTC and the community it serves."

With the addition of the new buses, fueling volume at the two stations is expected to exceed 1,500,000 gallons per year beginning in 2009.
