CDP Disclosure Cycle 2025
Environmental disclosure is now more important than ever.
In our 25th year, we look forward to partnering with you to facilitate disclosure that is critical for driving Earth-positive change. This year, Requester and Discloser feedback is at the heart of our approach to the disclosure cycle, with Portal stability and core functionality among our areas of focus.
Here on our Disclosure Hub, you can find key updates, documents and information for the cycle.
In these uncertain times, disclosure is unlocking powerful information to drive business critical decisions that drive impact across the value chain.
Disclosure data helps future-proof your business models, embedding resilience against systemic risks and identifying efficiencies across operations and the supply chain.
Disclosure is driving performance. Environmental leaders are identifying new opportunities for growth, from unlocking capital to galvanizing customer buy-in for the long-term.

Why disclose?
Disclosing through CDP puts the right data in the hands of those who can make changes the planet and economy need.

Request data
Find out how to request organizations to disclose and how we’re improving the process.

Letter to the Board
CDP’s annual ‘Letter to the Board’ is sent to companies' senior stakeholders, formally inviting them to disclose environmental information.
Self-Selected Organizations
Self-Selected Companies are organizations (companies, cities, states, or regions) who volunteer or choose to ‘self-disclose’ to CDP without a Supply Chain or Investor request. Similarly, Supply Chain-requested organizations that would also like to respond to Capital Markets and/or to receive a public score.
If you have not received an official Supply Chain request or email requesting you to disclose for 2025, please fill out and submit the Register to Disclose form via our Help Center.
