The federal government is making it easier for consumers to buy an eco-friendly vehicle. New fuel economy window stickers released today detail annual fuel costs and fuel-costs savings and give greenhouse-gas ratings.

The stickers will start appearing on 2013 models. It's a little busy with information, and the environmental community was pushing for a different model that gave each car an overall A to D letter grade for its fuel economy and pollution impact. That version would have required less effort from dense consumers.

The new model has plenty of fine print to trip people up: It notes, for instance, that although electric vehicles get the highest greenhouse rating, that rating doesn't take into account the emissions that go into creating the electricity that powers the car. But who'll be reading that tiny-lettered section of the label? As we say on the internet, TL;DR.
