Clean Energy Appoints Refuse Sector Veteran Executive Raymond Burke to Spearhead Strategic Growth Effort.

SEAL BEACH, Calif. -- Clean Energy (Nasdaq:CLNE), North America's leader in clean transportation, has appointed refuse sector veteran Raymond Burke to the newly-created post of vice president, business development, with a focus on developing new strategic growth opportunities for Clean Energy in the solid waste industry. His efforts will stress outreach efforts aimed at educating waste industry leaders on the benefits of using clean-burning natural gas fuel (CNG and LNG) for their trash collection fleets.

Burke has amassed 30 years of waste industry experience, including 25 years of increasingly responsible management posts with Waste Management, one of America's largest refuse companies. Most recently, he served as Waste Management's Southern California Area Vice President, responsible for the financial performance of operational assets valued at $800 million. Burke began his career at a 50-route disposal company in Anaheim, CA, where he held varied operational posts leading up to General Manager.

"We are delighted that Ray has chosen to bring his significant refuse sector experience and leadership skills to Clean Energy," said James Harger, Clean Energy Senior Vice President, Marketing and Sales. "Our company has a growing position in the solid waste industry, which is increasing deployment of natural gas refuse collection vehicles across the nation. Already, Ray's contributions to our continuing outreach efforts in this sector have been substantial and valuable," Harger added.

Burke holds an MBA degree from Chapman University, Orange, CA, and a BS degree in business administration from Northern Arizona University.
