CDP
CDP — global environmental disclosure platform
CDP runs the world’s largest environmental disclosure system. Through a single annual questionnaire, companies report their climate, water and forests data — mainly at the request of investors and customers. It is run by a non-profit, free for companies to disclose through, and used by over 20,000 companies worldwide.

Who reports under it
Companies of any size asked by investors or large customers to disclose environmental data. Disclosing through CDP is voluntary and free, and increasingly expected across supply chains.
How CDP works
Companies complete one annual questionnaire covering climate change, water security and forests, aligned since 2024 with the ISSB’s IFRS S2 and organised around the TCFD.
Submissions are scored from A to D based on completeness and environmental performance, with the top performers reaching CDP’s well-known “A List”.
Why CDP matters
CDP is one of the most recognised ways to answer investor and customer environmental requests with a single, comparable submission. Because it now aligns with IFRS S2 and the TCFD, disclosing through CDP also prepares you for those frameworks — all built on GHG Protocol emissions data.
Frequently asked questions
Is it free to disclose through CDP?
Yes. CDP is a non-profit and companies can disclose through its questionnaire for free. CDP is funded mainly by investors, members and governments rather than by charging disclosing companies.
How does CDP relate to other frameworks?
CDP’s questionnaire is aligned with the ISSB’s IFRS S2 and the TCFD, and maps to frameworks like the CSRD. Disclosing through CDP therefore reuses the same GHG Protocol emissions data you need elsewhere.
