There are a number of key dates to be aware of in CDP’s annual disclosure cycle, outlined below. The most important of these are the CDP Portal opening date and the scoring deadline. This year, the timeline for Portal opening, scoring deadline and Portal closure will be the same for all disclosers.

Please note, Disclosers who are eligible for scoring, but do not submit their questionnaire response before the scoring deadline will miss out on the chance to receive a score.
The questionnaire for each year is made available to view in advance via our guidance pages. We recommend Disclosers familiarize themselves with the questionnaire and start preparing their responses prior to the Portal opening.  Find your relevant questionnaire and guidance material at the following links for companies, cities, or states and regionsKey changes for disclosure in 2024 are further outlined on our page here
