CarbonFund    

Most of us drive a car, burning an average of 10,000 pounds of CO2 each year, which contributes to global warming. But for about $50 (tax-deductible), you can make your car CO2-neutral for the year by financing projects to sequester 10,000 pounds of CO2 during the year. Very clever, and very cheap! (...twice as effective as buying a hybrid, and FAR less expensive!)

I used to recommend Terrapass, but now recommend Carbonfund, instead, for several reasons. First, they have better prices (per ton CO2). Second, they're a nonprofit (which also means you can deduct your donation).
