The UK arm of The Coca-Cola Co. and Coca-Cola Enterprises (CCE) has publicly announced the carbon footprints of their major soft drinks brands.

Coca-Cola Great Britain (CCGB) and CCE said today (9 March) that, following collaboration with the Carbon Trust in the UK, a 330ml can of Coke sold in the UK has a carbon footprint of 170 grams, while the same sized can of Diet Coke or Coke Zero has a footprint of 150 grams. A 330ml glass bottle of Coke, meanwhile, has a footprint of 360 grams.

In calculating the greenhouse gas emissions, the companies, both of which are part of the Coca-Cola system, looked at the ingredients used to make the drink, the manufacture of the drink and its packaging, the impact of distribution and retailing, use of the product by individual consumers and the disposal of the empty bottle or can.

Speaking to just-drinks today, however, a spokesperson for CCGB said that there were no plans to include the carbon footprint details on the packaging of their brands. "Research has shown that consumers respond more to recycling messages," the spokesperson said. The public will be able to access information on the companies' carbon footprints at cokecorporateresponsibility.co.uk.

Sanjay Guha, president of Coca-Cola, Great Britain and Ireland, said: "A clear measurement of the carbon emissions of individual products is a vital step on our journey to reduce them and to achieve our goal of operating in a responsible and sustainable way.

"As we move forward, we will look to integrate the carbon footprint information with other key environmental impacts, for example water, and explore how best to share the total environmental impact of our products with consumers."

Simon Baldry, managing director of CCE GB, added: "We are determined to deliver the transparency and progress that our customers need in this area. It is the first time this analysis has been undertaken for soft drinks in GB."

At the same time, the companies said they are looking to roll out a nationwide series of branded recycle zones in the country. Six zones have already been launched including at Thorpe Park, Festival Place in Basingstoke and the University of Warwick.
