BUSINESS MEMO: AUTO POLLUTION

Detroit's automakers sell vehicles that create more pollution than most other major auto manufacturers, according to a study by an environmental group.

The reason: Pickups and sport utility vehicles, dear to American automakers' profits, that burn more gas and emit more pollution than passenger cars, the Union of Concerned Scientists said Wednesday.

But automakers said the ranking relied too much on fuel economy, hurting those companies that build larger trucks and SUVs. Under federal rules, trucks are allowed higher emissions and lower gas mileage than cars.

The UCS study ranked Honda as the least-polluting automaker, with Subaru second.
