Clean Energy Co-Founder T. Boone Pickens Remains Bullish on the Company

The following statement should be attributed to Andrew J. Littlefair, president and CEO of Clean Energy Fuels Corp. (NASDAQ: CLNE).

“My co-founder, Boone Pickens, let me know that he has filed a Form 144 to sell a small portion of his overall holdings in Clean Energy, up to 3 million shares. He emphasized that he still remains as bullish as ever on the company’s future and the benefits of natural gas as a transportation fuel, validated by the growing number of vehicle fleets fueling at Clean Energy stations. Boone will continue to be our largest shareholder, an active member of the company’s board of directors and a valuable energy expert for us to tap into.”

Natural gas fuel costs up to $1.00 less than gasoline or diesel, depending on local market conditions. The use of natural gas fuel also reduces greenhouse gas emissions up to 30% in light-duty vehicles and 23% in medium to heavy-duty vehicles. In addition, nearly all natural gas consumed in North America is produced in North America.
