Washington-- The State Ecology Department says transportation vehicles--planes, trains, and cars--are the leading contributor to greenhouse gases entering the ozone.
And that is why starting next year, they'll be putting labels on new cars. It's an environmental performance level label that shows you exactly how much smog it lets out, and it's overall greenhouse effect.
The Department says it's their way to educate you on the environment, and they say it may even impact what car you drive off the lot in.
"People have a chance to be able to look at different vehicles and see what kind of contribution this specific type of vehicle makes to greenhouse gases and that may affect their purchasing decision," says Seth Preston, Ecology Communications Manager.
Not all cars will have these new labels. They're expected to be on the windows of passenger cars, light-duty trucks and most vans and SUVs starting in 2009. Without the sticker, cars won't be sold.
The Ecology Department says this may also influence car-makers to reduce the amount of emissions.
