CDP Disclosure 2026
Twenty-five years since CDP was founded, environmental disclosure is more important than ever. Disclosure and a CDP score help you manage risk and understand opportunities. They are used to inform investment and procurement decisions across the globe, serving as a powerful signal to the market, investors and customers of your commitment to Earth-positive action.
We look forward to working with you to enable critical disclosure in 2026. We will continue to update this hub page with more information (including further details around questionnaire changes), key dates and materials for the upcoming cycle so you can prepare to disclose.

Changes to the 2026 questionnaire
In 2026, we will be making some changes to the questionnaire to support organizations navigating an increasingly complex global landscape. From accelerating climate impacts to resource insecurity and biodiversity loss, markets need intelligence that fills critical data gaps.
High quality data helps organizations navigate risk, build resilience and identify opportunities for Earth-positive action.
CDP’s 2026 updates are designed to strengthen the link between data and action. We are committed to:
Deepening alignment with global standards;
Expanding our coverage to ocean; and
Enhancing the usability and accessibility of the data we surface.
