Carbon Disclosure Project (CDP)2012.03.19
The Carbon Disclosure Project (CDP) represents 655 institutional investors and 50 purchasing organisations, as well as governmental bodies. The CDP issues an annual questionnaire to thousands of companies worldwide on behalf of the above groups. The survey asks participating companies to provide information on their view of the risks and opportunities presented by climate change, along with Greenhouse Gas emission accounting schemes, strategies for reducing GHG emissions and corporate governance polices relating to climate change.
Every year, the Carbon Disclosure Project publishes Global Reports and Leadership Indices based on the data collected. The CDP Global 500 report examines carbon reduction activities among the world's largest public corporations, qualifying the ones with top scores for disclosure to be listed in the Carbon Disclosure Leadership Index (CDLI).
Companies are encouraged to report their emissions data using the Greenhouse Gas (GHG) Protocol, which is the most widely used international accounting tool applied by governments and business leaders to quantify and manage greenhouse gas emissions.
