Request Data

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, members, signatories, 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;
Private Markets requesters such as asset owners and fund managers with private market portfolios;
Banks providing supply chain financing solutions to their corporate customers;
CDP Capital Markets Signatories seeking reported environmental data from public companies and subnational governments (that they hold ownership in, through equity or investment through debt), to make their portfolios more resilient and ensure long-term sustainability;
Associations and coalitions such as RE100, C40 Cities, ICLEI, the Global Covenant of Mayors, Regions4 and the Under2 Coalition;
Subnational governments; and
Environmental campaigns, pledges, programs and other civil society organizations working with companies and subnational governments to drive Earth-positive action.
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.
