The Canmaker. March 12: Drinks cans have the lowest carbon footprint within the range of packaging used by Coca-Cola in the UK, according a report published this week in collaboration with the Carbon Trust. It is the first time in Europe that the carbon footprint of packaged soft drinks has been certified by the Carbon Trust, an independent organisation set up by the UK Government that is committed to developing a low-carbon economy.
Both Coke Zero and Diet Coke in aluminium 33cl cans were found to have a carbon footprint of 150 grams while a comparable 33cl glass bottle of had a carbon footprint of 340g. A 50cl PET bottle for the drink recorded 200g and a 2-litre PET bottle came in at 400g. No data was provided for a 50cl can.
The research showed that packaging accounts for the largest portion of the drink’s carbon footprint, between 30 and 70 percent, depending on the type of container used. However, the research went on to highlight the importance of both using recycled content and of encouraging recycling post use. A combination of these two factors can decrease the overall carbon footprint of a product by up to 60 percent.
