Request Data

CDP Supply Chain members work with CDP to encourage their own suppliers to engage on environmental issues and performance, and to disclose through CDP. This way, Supply Chain members – and their sustainability, procurement and financial teams – can pinpoint risks and identify opportunities in their upstream value chain.

In 2025, approximately 45,000 suppliers were requested to disclose through CDP’s Supply Chain program.

Disclosers responding to such a request will be asked to respond to relevant supply chain questions in addition to the main questionnaire.

CDP sends its annual 'Letter to the Board' to senior stakeholders, formally inviting them to disclose on behalf of our Capital Markets Signatories – financial institutions that own or manage financial assets.

Capital Markets Signatories use disclosure data to create products, identify and assess risks across their portfolio, and engage stakeholders.

Unlike other Requesters, Capital Markets Signatories don’t create or manage their Request list. Instead, they use a CDP-created sample list. CDP recognizes that all industrial activities have a significant role to play in reducing environmental impact as we transition to a sustainable economy. We therefore apply several criteria to identify companies who are most relevant to capital markets actors. Find out more about our sample methodology.

In 2026, hundreds of financial institutions with US$110+ trillion in assets are requesting over 43,000 organizations to disclose.

CDP's Non-Disclosure Campaign (NDC) runs alongside the main CDP disclosure request. The campaign leverages the power of direct engagement from financial institutions to drive corporate environmental disclosure and boost transparency.

It is supported by CDP’s Capital Markets Signatories, some of whom take on a lead role. During the disclosure period, lead participants engage with targeted companies to drive them to disclose, with support from CDP’s NDC team.

Analysis shows that companies are more than twice as likely to respond and disclose if they are engaged directly through the campaign.

To ensure requests reach the right disclosing organization and that we build the most accurate and comprehensive database of environmental information, every disclosing company in the CDP database is identified with a unique Dun & Bradstreet Universal Numbering System (DUNS) number.

Companies of all sizes can register for a DUNS number from anywhere in the world. Cities, states and regions, and some other organizations are not assigned DUNS numbers.

You can find a company’s DUNS number in the CDP Portal. Simply use the search-and-find tool on the CDP Portal to look up organizations you would like to request. You can search using a company's name and country of headquarters to retrieve their DUNS number and parent company options. Make sure your spelling is correct and start with the company’s registered office address before trying different names or aliases which the company might be known by.

If you cannot find the correct company details on the Portal, you can carry out an extended search. If the search provides incorrect details, you must contact Dun & Bradstreet, as only they can correct the source of this information. Please only add information you know is correct for the organization you're searching for.
