Torn between wines from Napa and Bordeaux? Well, if Dr. Tyler Colman had his way, you wouldn't be selecting your alcohol solely based on your palette anymore. Instead, he'd have you refer to the "Green Line," or the Mason Dixon Line for Wine, wine's national carbon footprint line that runs through Ohio all the way down to Texas.

Colman also studied organic versus non-organic farming and found that organic only reduced Greenhouse Gas (GHG) intensity by a small amount. Transportation, rather than the way in which the wine is grown, is more significant to a wine's carbon footprint.
Need to see the numbers for yourself? The study, "Red, White and 'Green': The Cost of Carbon in the Global Wine Trade" by Tyler Colman and Pablo Paster is available here for more information.
