# Request Data
#### For over 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](/en/about.md), Requesters can access a standardized, globally comparable data set that [has many uses](/en/data.md).
Continue reading to learn more about who can request data, how to request for the 2026 disclosure cycle, and more. [Visit our Disclosure Hub](https://www.cdp.net/en/disclosure-2026) for key dates and information for the 2026 cycle.
## Who can request data through CDP?
Each year, hundreds of organizations request or engage their suppliers, portfolios, members, and other stakeholders to report key environmental data, by disclosing through CDP.
Requesters can include:
- [CDP Supply Chain](https://www.cdp.net/en/supply-chain) members, typically large purchasing organizations looking to future-proof their supply chains – this is also referred to as a ‘customer request’ or ‘Supply Chain request’;
- [CDP Capital Markets Signatories](https://www.cdp.net/en/capital-markets-signatories) (via CDP’s [Letter to the Board](/en/disclosure-2026/letter-to-the-board-2026.md)) seeking reported environmental data from public companies (that they hold ownership in, through equity or investment through debt), to make their portfolios more resilient and ensure long-term sustainability;
- Data users who [license our data](/en/data-licenses.md), such as academics, companies, financial institutions, NGOs and charities;
- [Private Markets](https://www.cdp.net/en/private-markets) such as asset owners and fund managers with private market portfolios;
- [Banks](https://www.cdp.net/en/corporate-banking-program) providing supply chain financing solutions to their corporate customers;
- 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.
[Read our FAQs below](#faqs) to learn more about these types of requests and Requesters.
## How is CDP data used?
CDP data – both scored and unscored – is utilized by a huge range of stakeholders including companies, financial institutions, policymakers, and non-governmental organizations such as:
- L’Oréal to strengthen procurement requirements and build supply chain resilience;
- Arkéa Asset Management to power their Water Security & Transparency fund and identify companies incorporating water security management into their strategy; and
- The Intergovernmental Panel on Climate Change (IPCC) and World Bank to inform stronger policymaking.
CDP data is available through our membership services and licensing agreements. It is also publicly available on our website and in the reports and policy briefings we publish. [Filter and explore our datasets](https://cdp.net/en/data) to learn more.

## How to request data
Below is a summary of how to request environmental data through CDP in 2026.
**You can find a more detailed, step-by-step checklist on our dedicated **[**Requester Hub**](https://requesters.cdp.net/)** **covering Portal access, building and submitting Request lists, and tracking suppliers.
Find key dates and further information for the 2026 cycle [on our Disclosure Hub](/en/disclosure-2026.md).
### 1. Access the CDP Portal
If you are a new contact or user, you will need to be [added as a team member to your organization](https://help.cdp.net/en-us/knowledgebase/article/KA-01016) and set up with a Requester role. Either a colleague can invite you or you can contact your CDP Account Manager to set you up.
If your organization is an association or coalition, a government, or an environmental campaign, pledge, program and other civil society organization, please raise a case via My Support on the [CDP Help Center](https://help.cdp.net/en-US/) and we can provide more information on requesting data.
Learn more about [accessing and navigating the Portal](https://help.cdp.net/en-us/knowledgebase/article/KA-01006).
### 2. Create your Request list
Once you have access to the Portal, you can start building your Request list (ie the list of organizations you are requesting to disclose through CDP). Note, this does **not** apply to Capital Markets requests.
Returning Requesters can copy a list from the previous disclosure year and edit this for the current cycle as needed.
Both new and returning Requesters can [add organizations to their list](https://help.cdp.net/en-us/knowledgebase/article/KA-01011) from the CDP database. They also have the option initially to make [bulk edits to their list using a CSV file](https://help.cdp.net/en-us/knowledgebase/article/KA-01012) once all organizations in their list have a Data Universal Numbering System (DUNS) number – learn more about DUNS numbers below.
**To ensure CDP has the right contact information for your requested organizations **(so they can access their account and disclose), you can either:
- Provide your requested organizations’ email address/addresses in your Request list; or
- Direct requested organizations to complete the Register to Disclose form, once this is available from disclosure launch.
Requesters may have the option to provide their organizations' details using domain-based invites. Please speak to your Account Manager for more information.
If you were not able to share your requested organization’s contact details, you will need to ask them to complete our [Register to Disclose form](https://help.cdp.net/en-US/Register-to-Disclose/) to join the Portal**.**

### 3. Submit your Request list
You can [submit your Request list](https://help.cdp.net/en-us/knowledgebase/article/KA-01011) once this is completed.
**The deadline to submit your final Request list is the week of June 8**,** **so requested organizations have sufficient time to respond and disclose. You can continue to add organizations to your list after this date, but they may decline your request. Read more about updating your Request list after submission, below.
Once your list is submitted, your requested organizations will receive an email request to disclose.
### 4. Update your Request list (after submission)
If necessary, you can still add and/or remove organizations on your Request list after submitting this. For any new organizations you wish to add, you will need to provide CDP with specific contact information for them.
**You will need to resubmit your Request list after you have finished making any changes. **Note that any changes submitted **after **the Request list deadline (week of June 8) will need to be approved by the requested organization.
### 5. Track your Request list
Once you have submitted your Request list, you can begin to [track your requested organizations’ disclosure status and progress](https://help.cdp.net/en-us/knowledgebase/article/KA-01007).
**The scoring deadline for Disclosers is September 16.** The platform will close for Disclosers on the final response deadline, on the week of October 26.
## FAQs
### What is a “customer (Supply Chain) request”?
[CDP Supply Chain members](https://www.cdp.net/en/supply-chain) 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.
### What is a “Capital Markets request”?
CDP sends its annual ['Letter to the Board'](/en/disclosure-2026/letter-to-the-board-2026.md) to senior stakeholders, formally inviting them to disclose on behalf of our [Capital Markets Signatories](/en/capital-markets-signatories.md) – 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](https://assets.ctfassets.net/v7uy4j80khf8/48zRdnAXySABj6xeTEdtSj/317416a3d97257249a9bb033dc25b03b/CDP_Capital_Markets_Request_â___2026_Sample_Methodology.pdf).
In 2026, hundreds of financial institutions with US$110+ trillion in assets are requesting over 43,000 organizations to disclose.
### What is CDP’s Non-Disclosure Campaign?
CDP's [Non-Disclosure Campaign (NDC)](/en/campaigns/non-disclosure-campaign.md) 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.
### How does CDP use the Dun & Bradstreet database to improve the request process?
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.
