I was poking around Opel’s UK site today and saw something neat. Instead of posting fuel economy for the various engines and body styles, they post the CO2 emissions. For example, instead of 35 miles per gallon, they show 140 grams per kilometer. Aside from being metric, which is much, much better than imperial, this provides a way for consumers to make a better choice as to how their automobile will affect the climate. And because hydrogen or electric cars produce carbon emissions of their own, depending on how the electricity or hydrogen is produced, you can take that into account when comparing the two.
This is definitely something I think that the EPA should mandate for US cars.
