Fintura GreenPay Mastercard

Why It's Good:

So much easier than carrying a wad of cash around, Mastercard is accepted at most places and this one has no annual fee.

Why It's Green:

The card is made from recycled plastic. When you activate your account, you'll automatically offset 10,000 pounds of CO² (the average annual emission of a car in the US). For every net dollar you spend, the company will invest in energy efficient projects to offset five pounds of CO².

Must-Have Mastercard

Though credit counselors, financial advice columnists and my fiscal killjoy of an ex-boyfriend might beg to differ, expanding your credit card wardrobe can be a good thing. At least in one case: The Fintura Corporation has just introduced its GreenPay Mastercard, the carbon-offsetting answer to all those mileage-earning wonders in your wallet. For every net dollar you put on this particular piece of plastic (recycled, natch), five pounds of CO² will be "retired"—a term that would seem to imply a CO² mahjongg league in Boca, but that in fact refers to energy efficiency projects that absorb or prevent the release of CO². You'll also get the eco-equivalent of a signing bonus: When you activate your account, you'll automatically offset 10,000 pounds of CO² (the average annual emission of a car in the US). Flagrant assuaging of consumerist guilt? Perhaps. A great idea anyway? Absolutely. —Abbie Kozolchyk
