Shopping to save world, again

Concerned about that whole environment thingy? Looking for more ways your shopping can save the world? Well, Marketplace had a curious report that might interest you. It was about a GE credit card that puts one percent of your spending on that card toward carbon offsets. A GE rep explained:

A typical individual has a carbon output of 10 tons per year. And if you spend $750 per month on our card, you would generate enough rewards to fund carbon offsets which could completely neutralize those 10 tons.
