The Comité Interprofessionel du Vin de Champagne (CIVC) reports that almost all Champagne houses within two years will use a new, lighter bottle model. The new 75cl Champagne bottle weighs only 835 grams, or 29.5 ounces. The current Champagne bottle weighs 900 grams, or 31.7 ounces. That is 7.2 percent more. The lighter bottles will save on materials and transportation costs and is more environmentally friendly. The new Champagne bottle will reduce CO2 emissions by 8,000 metric tons a year, equivalent to the annual emissions of 4,000 cars. The new bottle is as sturdy as the old, and costs the same. The Champagne industry wants to cut its carbon footprint by 25 percent by 2020.
