In partnership with the Carbon Trust, Cadbury has, for the first time, calculated the carbon footprint for milk chocolate and discovered that milk contributes to just over 60% of emissions. As a result, the partnership - which is part of Cadbury's broader 'Purple Goes Green' environmental initiative - will undertake a pilot programme working with dairy farmers in Selkley Vale in Wiltshire and Gloucestershire, providing practical advice to help farmers reduce emissions. It includes a Cadbury Guide to Low Carbon Dairy Farming - a best practice guide to reduce the carbon impact of dairy farming.
