The company reported that it secures raw material for paper cartons in cooperation with the World Wide Fund for Nature (WWF), the Global Forest & Trade Network (GFTN) and Forest Stewardship Council (FSC) and that it strives to source polyethylene made from sugarcane from sustainable suppliers in Brazil. In 2010, 40 percent of Tetra Pak's carton supply was FSC-certified. Slowly, sectors where glass bottles have been paramount, like the wine and spirits industry, have begun to look at carton containers as a possible packaging product as the carbon footprint of a carton container is said to be about one-tenth of that of an equivalent glass bottle.
