The 2007 Automaker Rankings in Environmental Performance

Considering that environmental concern is now on top of the priorities of governments and people worldwide, automakers are eager to deliver better performance to meet these demands. Now the automakers’ efforts are going to be boosted by the “Automaker Rankings 2007: The Environmental Performance of Car Companies”.

Under the process of ranking, the bottom-line environmental performance of eight companies was analyzed. Together, all the eight companies cover 96 percent of cars and trucks sold in the United States, the world’s largest vehicle market. The analysis makes use of the sales and emissions data from the U.S. Environmental Protection Agency and Department of Transportation for model year 2005. The scores come from a 50/50 weighting of average per-mile emissions of smog-forming and global warming pollutants from each automaker’s vehicles. The average of all the eight automakers is considered a score of 100, where lower scores mean less pollution.

In that case, all the automakers should be doing better. They should all be looking forward in using conventional technologies that can cut global warming emissions and hybrids that could further reduce emissions.

Even we, consumers, should take part in the campaign. We should be purchasing a car or truck that has the lowest emissions and highest fuel economy, of which of course also depends on our needs and budget. Our preference signals the automakers that we care about the environmental impact of our vehicle choices.

An article in ucsusa.org has featured the automaker’s key findings, which are as follows:

• Honda retains its title as the Greenest Automaker. Honda has the best smog performance in four out of the five classes of vehicles it produced, and better-than-average global warming scores in every class.
• Toyota is nipping at Honda's bumper. Toyota is the only major automaker to consistently improve global warming performance since 2001, thanks to hybrids and better conventional technology.
• Hyundai-Kia wins bronze in its debut appearance. Hyundai-Kia's vehicles have better-than-average performance on both smog and global warming pollution.
• Nissan slips from its second-place finish in our last ranking. Nissan could have made the top three had it not taken advantage of a loophole that artificially inflates fuel economy ratings for dual-fuel (gasoline/ethanol) vehicles.
• Volkswagen's vehicles disappoint. VW cars are some of the dirtiest, when compared with others in the same classes. Cleaner diesel and gasoline vehicles are a key to future success.
• Ford is the best of the worst. Ford could have tied for third place on global warming performance if it had matched the reductions in global warming pollutants it has achieved in its European fleet since 1997.
• General Motors crawls out of the basement — barely. GM is the top peddler of vehicles rated at 15 mpg or worse in city driving.
• DaimlerChrysler is Public Polluter #1, with the worst global warming performance in half the classes in which it produces vehicles. Its small pickup trucks produce more smog than any class of vehicles from any other automaker.

It also featured the following examples of important lessons from the Automaker Rankings 2007 analysis:

• Size is no excuse for a dirty fleet. Toyota is a full-line manufacturer, producing vehicles in every class evaluated, yet it nearly ties Honda's global warming score—despite the fact that Honda did not make pickups, large cars, or large SUVs in 2005.
• Consistency is key. The top two finishers, Honda and Toyota, are the only two automakers with consistently better-than-average performance in both the smog and global warming categories in nearly every vehicle class. In contrast, GM undermines its leadership in some vehicle classes with poor performance elsewhere.
• Many greener choices are hot sellers. Nearly one of every two vehicles Toyota sold in model year 2005 was the best model in its class in one or more environmental categories. Similarly, one in four of Honda’s vehicles and one in five of Hyundai-Kia’s were the best models in their classes.

So now, you know how the eight automakers have been working very well to provide the best for us.
