The Carbon Disclosure Project (CDP)’s Water Disclosure provides critical water-related data from the world’s largest corporations to inform the global market place on investment risk and commercial opportunity. The project requests information on the risks and opportunities companies face in relation to water; on water usage and exposure to water stress in companies’ own operations and in their supply chains; and on companies’ water management plans and governance. In 2010 CDP sent its first annual water questionnaire to 302 of the world’s largest 500 companies in the FTSE Global Equity Index Series (the ‘Global 500’), focusing on sectors that are water-intensive or particularly exposed to water-related risk.
