Nissan vehicles put out more carbon emissions
Nissan vehicles put out more carbon, study finds
Toyota reduces its emission rate
August 31, 2007

Nissan Motor Co.'s vehicles had the biggest increase in carbon-emission rates over 15 years among the six biggest sellers of automobiles in the United States, according to a report by an environmental group.
The average lifetime carbon emissions for Nissan's 2005 fleet rose 9.2% from 1990 as the company added more light trucks with poorer fuel economy, Environmental Defense, an advocacy group based in Washington, said Thursday.
Toyota Motor Corp.'s average emission rate fell 3% during that span.
Next week, Congress returns to sessions and lawmakers such as John Dingell, D-Mich., have said they will propose laws to reduce U.S. carbon emissions.
Cars and light trucks account for about 20% of the country's carbon output, which contributes to global warming.
"Market shifts to date fall far short of what would be needed to truly address global warming," wrote John DeCicco, the study's lead author. "New policies will be needed to significantly limit automobile carbon burdens."
DaimlerChrysler AG's fleet had the second-highest increase in emissions during those 15 years at 4.8%, followed by Honda Motor Co.'s 4.4% and Ford Motor Co.'s 4.3%. General Motors Corp.'s average rose 3%.
"Since the end of this report in 2005, we have added the subcompact Nissan Versa, Altima Hybrid and flex-fuel-capable trucks," Nissan spokeswoman Jeannine Ginivan said in an e-mail.
She said Nissan "has committed to a comprehensive plan to reduce carbon-dioxide emissions and to improve fuel economy."
Hybrid vehicles reduce emissions by generating some power from an electric motor, burning less fuel for each mile traveled.
Flex-fuel vehicles can run on conventional gasoline or E85, a blend containing 85% ethanol.
The rising emission rates in the United States stem from an increase in demand for pickup trucks, minivans and sport-utility vehicles, which generally get poorer fuel economy than passenger cars, the study said.
An increase in total miles driven and the number of cars on the road also pushed up total emissions.
Toyota's shrinking emission rate is due to its hybrid Prius and improving fuel economy in its conventional gasoline cars, such as the Corolla sedan, DeCicco said at a news conference.

Among the Japanese big 3 Toyota has certainly led the charge in reduced emissions. Nissan should imp[orve in this area over the next few years with it's continued development of hybrid, fuel cell and diesel powerplants.
I'm surprised to see Honda where it is. I always thought Honda was a "greener" company.
