Carbon Disclosure Project (CDP)

This web site is the largest registry of corporate greenhouse gas emissions in the world. Responses from corporations can be downloaded without charge.

The Carbon Disclosure Project (CDP) provides a secretariat for the world's largest institutional investor collaboration on the business implications of climate change. CDP represents an efficient process whereby many institutional investors collectively sign a single global request for disclosure of information on Greenhouse Gas Emissions. CDP has historically sent this request to the FT500 largest companies in the world.
