PASADENA, Calif. -- CALSTART - North America's leading advanced transportation technologies consortium - today announced the 2007 winners of its prestigious Blue Sky Awards[TM], selected for their market leadership and real actions in advanced transportation. The awards recognize outstanding marketplace contributions to clean air, energy efficiency and to the clean transportation industry overall by companies, organizations and individuals.

"This year's Blue Sky Award[TM] winners are at the forefront of the fight to improve air quality, combat global warming, ensure our energy independence and to create sustainable, quality jobs," said CALSTART President and CEO John Boesel. "From clean and renewable fuels to more efficient vehicles, policies and investments, these winners exemplify the award's vision: taking clean and sustainable transportation products to the marketplace."

For more than ten years, CALSTART's Blue Sky Award[TM] has honored marketplace actions. Award recipients are selected for bringing new vehicles, fuels or technologies to market; for significant implementation of clean, sustainable transportation; or for significant technology or policy breakthroughs that affect the marketplace.

-- The 2007 Blue Sky Award[TM] is presented to Navistar International
   Corporation for its investment in the engineering, development,
   field assessment and 2007 production launch of medium-duty hybrid
   trucks earlier and faster than its competitors, making hybrids into
   a commercial product;

-- The 2007 Blue Sky Leadership Award[TM] honors the late Edouard
   Michelin, CEO and Managing Partner of the Michelin Group, for his
   global leadership to further advanced transportation technologies,
   most notably through the annual Challenge Bibendum vehicle
   efficiency competitions;

-- The Charles R. Imbrecht Blue Sky Innovation Award[TM] is given for
   innovative leadership actions in policy and technology that impacts
   and expands the clean transportation market. In an unprecedented
   decision, this year the award goes to two separate winners because
   of the global importance of both actions:

    -- To James Hankla of the Port of Long Beach and David Freeman of
       the Port of Los Angeles for their unprecedented work together
       and with their organizations to create and implement the San
       Pedro Bay Ports Clean Air Action Plan.

    -- To California Governor Arnold Schwarzenegger and California
       Assembly Speaker Fabian Nunez for their passage of landmark
       legislation AB32: The California Global Warming Solutions Act;

-- Three Blue Sky Merit Awards[TM] were awarded for meaningful actions
   supporting and expanding advanced transportation:

    -- Cummins Westport received a Blue Sky Merit Award[TM] for
       introducing and producing natural gas engines in a new market
       for heavier duty vehicles and for consistently meeting tough
       emission requirements in advance of regulations;

    -- Global Electric Motorcars (GEM), LLC received a Blue Sky Merit
       Award[TM] for both helping launch the battery-powered,
       neighborhood electric vehicle (NEV) market in 1998 and for
       continuing to improve, produce and expand vehicle sales in the
       years since;

    -- Venture capitalist Vinod Khosla received a Blue Sky Merit
       Award[TM] for his company's commitment to significant financial
       investments in the development of advanced transportation fuels
       and technology companies, leading the way for other investors
       in the process.

"Energy security and climate change worries have focused greater attention on the importance of advanced transportation," noted Boesel. "With nearly four dozen quality nominees, it's becoming increasingly more challenging to pick the most deserving winners."

CALSTART selects the award winners in a review process together with a multi-disciplinary selection panel made up of environmental and industry leaders, including representatives from the Natural Resources Defense Council, the American Lung Association of California and the Union of Concerned Scientists.

Award winners will formally receive their 2007 Blue Sky Awards[TM] at a gala luncheon to be held September 6, 2007 at the elegant Athenaeum Club on the campus of Caltech in Pasadena, California.
