Clean Energy Applauds Newly-Enacted State of Texas Legislation to Increase Natural Gas and Other Alternative Fuel Vehicle Use in Both State and Private Fleets

-New Regulations Aim at Curtailing Nitrogen Oxide Diesel Emissions, Improving
Air Quality, Lowering Fleet Fuel Costs, and Reducing Dependence on Foreign Oil-

SEAL BEACH, Calif.--(Business Wire)--
Clean Energy Fuels Corp. (Nasdaq:CLNE) today announced its support for newly
approved State of Texas legislation that is targeted to increase the number of
alternative fuel vehicles, including natural gas-fueled vehicles, in both state
agency and private vehicle fleets.

Providing financial incentives in the form of grant funding, the state`s new
Clean Fleet Program -SB1759- encourages private fleet owners to replace their
medium-to-heavy-duty diesel vehicles with alternative fueled-models, including
those powered by clean, green natural gas.

The Texas Clean Fleet Program, effective Sept. 1, 2009, initially allots $6
million per fiscal year for 2010 and 2011 to fleet owners to help fund their
vehicle replacement process. The legislation anticipates extending the program
through August 2017, which would represent funding of approximately $48 million
over the life of the program if funded at initial levels. The Clean Fleet
legislation amends the Texas Emissions Reduction Plan (TERP), enacted in 2001 to
improve air quality in Texas. The TERP program is aimed at reducing nitrogen
oxide emissions from diesel engines.

Companion legislation - newly-enacted HB 432 - amends the current state`s Fleet
Alternative Fuel Program to mandate that 50% of the state`s 27,000 fleet
vehicles must use clean alternatives fuels like compressed natural gas (CNG) 80%
of the time. The only exceptions are for law enforcement or emergency vehicles,
or if an agency demonstrates that it is not cost-effective to meet the
requirements. Although state agencies must meet the requirements by September 1,
2010, the legislation will likely be phased-in as diesel and gasoline-powered
state fleet vehicles come up for replacement.

Clean Energy (Nasdaq:CLNE) is the leading provider of natural gas (CNG and LNG)
for transportation in North America. It has a broad customer base in the refuse,
transit, ports, shuttle, taxi, trucking, airport and municipal fleet markets,
fueling more than 17,200 vehicles at 184 strategic locations across the United

in Willis, TX and one in Boron, CA, with combined capacity of 260,000 LNG
gallons per day and designed to expand to 340,000 LNG gallons per day as demand
increases. It also owns and operates a landfill gas facility in Dallas, TX that
produces renewable methane gas or biogas for delivery in the nation`s gas
pipeline network.
