They join Tesco, Cadbury Schweppes, Imperial Tobacco, Nestlé, Proctor & Gamble and Unilever - which announced in October 2007 that they will work with the CDP to encourage suppliers to provide data on their carbon dioxide emissions and climate change strategies (ENDS Report 393, p 4 ).
The project aims to develop a standardised approach to gathering supply chain data and help firms work with suppliers to reduce their carbon footprints. It hopes also to decrease the burden on suppliers that might receive several requests for similar information.
Each member has initially selected 50 suppliers to work with them. A pilot request will ask suppliers to report on their carbon footprint, greenhouse gas emissions, emission reduction targets and climate change strategy.
The results will be used to refine a full roll-out in May. CDP is inviting more firms to join the project. It thinks it could potentially bring tens of thousands of new suppliers into the CDP process.
"The supply chain leadership collaboration is a key step towards a unified business approach to climate change," said Paul Dickinson, chief executive of the CDP. "By bringing together the purchasing authority of some of the largest companies in the world, the CDP will encourage suppliers to measure and manage their greenhouse gas emissions. This will enable large companies to work towards measuring their total carbon footprint, as this is a key step to managing and reducing it."
