AUTOMAKER RANKINGS 2010

The Union of Concerned Scientists' 2010 Automaker Rankings evaluate eight major car companies using government data from model year 2008. Honda is ranked as the greenest automaker, while Chrysler is identified as the most polluting for the fourth time in ten years. The assessment emphasizes that overall environmental performance depends on cleaning up entire fleets, including high-volume sellers, rather than relying on a few niche green models.

• Honda is ranked as the greenest automaker for model year 2008, though it is closely followed by Toyota and Hyundai in a three-way tie for the top positions.
• Chrysler is the most polluting automaker of the year, marking the fourth time in five UCS assessments over a decade that it has held this position.
• The analysis concludes that achieving a high environmental ranking requires consistent performance across all vehicle classes and the sale of clean vehicles in high volumes, rather than just producing small cars or a few green models.
• Specific manufacturer trends include Toyota stalling on global warming emissions, Hyundai making significant strides to nearly win, and Volkswagen improving its smog rating due to a reduction in diesel models in 2008.
