  • Is the Hummer really Greener than the Prius? No.
    “Dust to Dust” Report Mislead the Media and Public with Bad Science

    (OAKLAND, Calif.) The CNW Marketing Research, Inc.’s 2007 “Dust to Dust: The Energy Cost of New Vehicles From Concept to Disposal” caught the interest of the media and the public with its claim that a Hummer H3 SUV has a lower life-cycle energy cost than a Toyota Prius hybrid. Closer inspection by the Pacific Institute, a nonpartisan think-tank, suggests that the report’s conclusions rely on faulty methods of analysis, untenable assumptions, selective use and presentation of data, and a complete lack of peer review. Re-analysis yields results that are often opposite of CNW’s conclusions.
    . . .
    The Institute calls on CNW to release its full report, including methods, assumptions, and data. Until “Dust to Dust” can be substantiated, the public and policymakers should ignore its conclusions. Unfortunately, “Dust to Dust” has already distorted the public debate.
