Boxed wine has always been looked down on as the cheap way to consume the most elegant of alcoholic beverages. However, an opinion article from the New York Times says that this image should change considering the carbon footprint created by trucking around glass bottles.
The vast majority (90% +) of American wine is produced on the West Coast, but then shipped to the East Coast where the majority of wine consumers live. This trucking process generates a tremendous amount of carbon-dioxide emissions. It is estimated that switching to lighter boxed wine for the 97% of wines that are made to be consumed within a year would reduce greenhouse gases by roughly 2 million tons or the equivalent of 400,000 cars.
Along with environmental advantages of boxed wine, it is also more economical from a cost per-glass perspective because of volume and preservation. It will be interesting to see if higher-quality wine producers jump on the boxed wine bandwagon and if consumers voice their sustainability demands on the wine producers.
