New York is requiring automobile manufacturers to affix “global warming index” stickers to new cars and passenger trucks beginning in the 2010 model year, Environmental News Service reports. The stickers will detail carbon dioxide and other greenhouse gases emitted by operating the vehicle. California has passed similar environmental legislation effective with the 2009 model year.
The index will be based on emissions of carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons and sulfur hexafluoride.
The requirement applies to passenger vehicles and light-duty trucks with a gross weight of 8,500 pounds or less.
Each sticker will include an index that compares the emissions of global warming gases from the vehicle with the average projected emissions from all vehicles of the same model year, and identifies the vehicle model within its class with the lowest emissions of that model year.
