Request Data
April 2 update: Visit our Disclosure Hub to download our 2025 questionnaire and guidance, and learn more about the minimal changes to this year’s corporate and SME questionnaires.

For 25 years, CDP has been the pioneer of environmental disclosure, and a trusted advisor in supplier engagement and environmental action.
Requesting through CDP creates the data needed to act. Through CDP, Requesters can access a standardized, globally comparable data set that has many uses.
For financial institutions, data from portfolio companies is critical to uncovering hidden risks and opportunities, providing the tools needed to inform risk-management practices, guide engagement priorities and integrate sustainability considerations into their investment process.
Who can request data?
Each year, hundreds of organizations request or engage their suppliers, portfolios, and other stakeholders to report key environmental data, by disclosing through CDP.
These requesters can include:
CDP Supply Chain members, typically large purchasing organizations looking to future-proof their supply chains;
Membership/initiatives such as RE100 and NZAM (The Net Zero Asset Managers initiative);
Private Markets requesters (ie asset owners and fund managers with private market portfolios); and
Banks providing supply chain financing solutions to their corporate customers.
Requesters use this data to inform decisions and drive environmental action.

Improving the request process with Dun & Bradstreet: Using unique identifiers
To ensure these requests reach the right organization and that we build the most accurate and comprehensive database of environmental information, CDP is working with the Dun & Bradstreet database of over 500 million companies and using Data Universal Numbering System (DUNS) numbers as a unique identifier.
Every company in the CDP database is identified with a unique DUNS number, provided by Dun & Bradstreet. Please note that cities, states and regions, and some other organizations are not assigned DUNS numbers.
