Clean Energy and Covanta Open First CNG Fueling Station in Nationwide Partnership to Transition Garbage Truck Fleets to Cleaner

Clean Energy and Covanta Open First CNG Fueling Station in Nationwide 
Partnership to Transition Garbage Truck Fleets to Cleaner Natural Gas 
Senior Government, Business, and Environmental Quality Leaders Mark
Opening at Covanta Essex Resource Recovery Facility in New Jersey 
NEWARK, NJ -- (Marketwired) -- 06/05/13 --  Clean Energy Fuels Corp.
(NASDAQ: CLNE) and Covanta Energy Corporation (NYSE: CVA), a world
leader in sustainable waste management and renewable energy, hosted
opening ceremonies today in Newark, N.J. for the first compressed
natural gas (CNG) fueling station built as part of a nationwide
partnership between the two companies to expand the CNG fueling
infrastructure across the country.  
The new station, built and maintained by Clean Energy onsite at
Covanta's energy-from-waste facility located in Newark, N.J., will
supply CNG fuel to refuse trucks serving communities and businesses
in Northern New Jersey and New York City. CNG fueling, combined with
Covanta's energy-from-waste facility, which processes post-recycled
municipal solid waste into clean, renewable electricity, creates a
compelling economic and environmentally-friendly refuse management
model the two companies plan to replicate across the United States.  
Senior government officials, business executives and community
leaders attended the grand opening ceremonies, which took place at
the Covanta Essex Resource Recovery Facility at 66 Blanchard Street
in Newark's East Ward.  
"Our overriding mission is to set a national standard for urban
transformation -- a goal that includes improving environmental
quality through transitioning to clean energy fuels for city vehicle
fleets," said Newark Mayor Booker. "To this end, we are moving
forward with a major program to replace our existing fleet of
diesel-powered garbage trucks and street sweepers with new
cleaner-operating CNG-fueled trucks. Our new fleet will fuel up here
at the Clean Energy/Covanta natural gas fueling station that
officially opens today." 
"Today we celebrate the first station developed by our partnership
with Covanta that we expect to bring cleaner and cheaper energy to
the Northern New Jersey area," said Andrew J. Littlefair, president
and CEO, Clean Energy. "This partnership is expected to enable more
fleets and customers around the country to take advantage of the
economic benefits of natural gas while reducing their carbon
footprint in the community -- a true win-win."  
Anthony Orlando, president and CEO, Covanta Energy, commented,
"Covanta is proud to partner with Clean Energy and the New Jersey
Clean Cities Coalition in the installation of the new fueling station
at our Energy-from-Waste Facility. CNG is the perfect complement to
our work in converting post-recycled waste into clean electricity.
This new CNG station is an important step in building out necessary
infrastructure to support the transition to modern fleets of garbage
trucks fueled by natural gas and that transition will provide
economic and environmental benefits to the communities we serve." 
Recovering energy from residual waste left over after recycling at
energy-from-waste facilities like Covanta Essex offsets greenhouse
gases and produces much needed renewable energy; reduces landfill use
which preserves open space; protects the environment by employing
state-of-the-art equipment and systems; and maximizes recycling and
the reuse of resources. 
This Clean Energy and Covanta CNG fueling station project is
partially funded by a U.S. Department of Energy Federal Stimulus
Grant through the New Jersey Clean Cities Coalition, a non-profit
organization that works to educate the public about the environmental
benefits of switching to vehicles powered by alternative fuels. 
Natural gas fuel costs up to $1.50 less per gallon than gasoline or
diesel, depending on local market conditions. The use of natural gas
fuel not only reduces operating costs for vehicles, but also reduces
greenhouse gas emissions up to 30% in light-duty vehicles and 23% in
medium to heavy-duty vehicles. The U.S. Department of Energy reports
that 98% of the natural gas consumed in the U.S. is sourced in the
U.S. and Canada, making natural gas a secure North American energy
