The Climate A List was established in 2011 and introduced for water and forests in 2015 and 2016 respectively. Because CDP’s climate program is more established, it has proportionately more responding companies, with more therefore achieving an A score in climate. A significantly smaller pool of organizations is asked to respond on forests and water. Where relevant, we encourage companies to disclose to all programs to achieve double or triple A status. An ‘F’ indicates a failure to provide sufficient information to be evaluated.
