The Obama administration has proposed new stickers for cars and light trucks that will make it easier to see whether you are buying a fuel-efficient one or a guzzler, and how much it contributes to global warming. They will include the traditional miles-per-gallon metric plus an estimate of the vehicle’s greenhouse gas emissions, as well as an estimate of annual fuel costs. Some even with a letter grade for fuel economy and greenhouse gas emissions, ranging from A+ to D. Some will not, but both systems of stickers will provide enough information for consumers to make good choices. The new standards cover the model years 2012 to 2016. Within the next couple of years, President Obama will propose even stricter standards for the model years 2017 to 2025. By then we could be looking at cars that get 60 miles per gallon — with new stickers.
