This article is for new Disclosers and provides guidance on how to complete the Register to disclose form. This form allows new users who wish to start reporting environmental data through CDP to request access to the CDP Portal and begin their disclosure journey. It is also used by organizations volunteering to self-disclose as a Self-Selected Company (SSC).
Throughout the disclosure process, we strongly recommend reviewing the relevant articles within the ‘Articles for Disclosers’ section of our Knowledge Base designed to support users with disclosing through CDP by providing answers to common questions and guidance on key processes.

Who should complete this form
Any new user from an organization that does not yet have access to the CDP Portal should complete this Register to disclose form.
If colleagues within your organization already have access to the CDP Portal, the fastest way to gain access to the Portal is for them to add you to your organization’s Portal account directly.
For further guidance on adding users, understanding Discloser roles, and managing team members access within the Portal, please refer to our article on adding team members to your CDP Portal.
