The Carbon Disclosure Project (CDP), a collaboration of over 315 institutional investors, including Goldman Sachs, Merrill Lynch, Allianz and HSBC, is now working with some of the world's largest companies to help them assess greenhouse gas (GHG) emissions through their supply chains. CDP has teamed up with some of the largest purchasing global organizations under the CDP Supply Chain Leadership Collaboration (SCLC). New corporate members include Dell, HP, L'Oreal, PepsiCo, and Reckitt Benckiser. They join original members Cadbury Schweppes, Imperial Tobacco, Nestlé, Procter & Gamble, Tesco and Unilever announced in October 2007. CDP is working with these global companies and their suppliers to create one single standardized approach to provide key climate change information throughout their supply chains. Each member of the Supply Chain Leadership Collaboration has selected up to 50 suppliers to work with them and to respond to the CDP pilot information request in the first quarter of 2008.
