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;
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 DUNS numbers as a unique identifier.
Every company in the CDP database is identified with a unique Data Universal Numbering System (DUNS) number, provided by Dun & Bradstreet. Please note that cities, states and regions, and some other organizations are not assigned DUNS numbers.
