  • Requested by customers and investors (see Climate change program)
    Companies receive the investor request in early February, and the supply chain request in early April. The main questionnaire must be submitted by June 30 and supply chain module submitted by July 30. Follow this step-by-step guide to submit to both CDP's climate change and/or water and supply chain questionnaires. (forthcoming).

Action Exchange

CDP action exchange program overview
For the first time, participating companies are asked to report this back to their requesting customers who are also Action Exchange members through SM2.2a in the supply chain module, attributing emissions reduction activities and achieved emissions reductions. Companies can also report further details of their emissions reduction activities in CC3.3b and by doing so can potentially improve both their CDP disclosure and performance scores.
