WASHINGTON (AP) - Car shoppers will receive more details on window stickers about fuel efficiency, emissions, energy costs and energy consumption under a new government proposal for 2012 model year vehicles.

The Transportation Department and Environmental Protection Agency are announcing the proposed stickers Monday. Options include letter grades of A+ to D for the vehicle's overall fuel economy and greenhouse gas emissions or keeping the current label's approach on miles per gallon and annual fuel costs with an updated design.

Consumers scan the window stickers when shopping for a new car or truck.

Officials say they want labels to give consumers straightforward information about the vehicle's affect on the environment.
