Wine Drinkers' Carbon Footprint

At least they are if you live in the Big Apple. A New Yorker leaves a smaller carbon footprint drinking a French Bordeaux shipped across the Atlantic (2.93 pounds of carbon per bottle) than drinking a Napa merlot (7.05 pounds). That's because when it comes to calculating carbon costs, the method of transportation matters as much as the distance. Shipping freight by sea generates less than half the emissions associated with airplanes and tractor-trailers.
