CDP Disclosure 2027

You can find the key dates for the 2027 disclosure cycle, below.

Next year’s cycle will begin earlier than it has in previous years so stakeholders can better use their data and scores to meet internal deadlines, inform planning, and leverage events and AGMs.

We will share more information about the 2027 cycle over the coming months on this Hub page, including any questionnaire changes. Please continue to check our 2026 Disclosure Hub for information about this year’s ongoing cycle.

FAQs

We have listened to feedback from our stakeholders, notably in the CDP post-disclosure survey, who have consistently told us they prefer the response window to open earlier in the calendar year. The 2027 Disclosure Cycle Milestones above are more aligned to the response window timeframes CDP practiced prior to 2024.

This ensures better alignment with mandatory reporting submissions, annual report publication, and the ability to leverage CDP scores and disclosure data sooner within the same calendar year.

Moving the cycle earlier directly responds to this feedback and enables customers to realize value from their data for the use of cases that matter most to them.

Communicating the milestone dates for the reporting window is the first of many updates concerning the 2027 Disclosure Cycle. Our goal is to provide as much advanced notice about improvements and updates to guidance and scoring methodologies as possible.

We constantly listen to feedback from our stakeholders to ensure that you can maximize the use of your disclosure and scores. Any subsequent changes to response window timeframes will be validated with our customers and communicated well in advance.

Our aim is to continually enable customers to unlock more value from their disclosure – whether that be from their CDP scores or CDP data products.

In 2027, we aim to deliver scores to Disclosers in September, publish the public score release in November, and continually deliver data products over the months following the response window closing. Exact dates for scores release and data product delivery will be communicated in due course.

We have brought forward scores release and other milestones in 2026 to provide as long as possible to understand and act on 2026 scores before the 2027 cycle opens.

The response window is one month shorter than in previous cycles. With improvements to the copy-forward function, the introduction of the new AI-enabled response suggestion feature, and no major changes expected to the questionnaire, we believe this remains a feasible timeframe for companies to complete their disclosures.

For 2026, On-Demand Extensions are available – details can be found in your relevant Scoring Introduction document. We expect to offer a similar approach for 2027.
