The CDP (formerly the "Carbon Disclosure Project") is an organisation based in the United Kingdom which works with shareholders and corporations to disclose the greenhouse gas (GHG) emissions of major corporations. As disclosure of emission related data as CDP's primary activity, the quality of the data reported to CDP is key. In 2014, nearly 2000 businesses reported climate change data to CDP. The value of CDP's reports for investors and NGOs is contested. Furthermore, the quality of the data on which CDP's reports are premised is questionable.
