How to Disclose

How to disclose: step-by-step

The CDP Portal contains key information about your organization’s disclosure, such as which people in your organization have access to the Portal and who has requested your organization to disclose. You can also view and update your organization’s details including your name, logo and organization description. Learn more about navigating the Portal

Returning users can sign into the CDP Portal. You will need to have a registered account and be added to your organization. If necessary, you can ask a colleague with existing access to add you as a team member to your organization.

New users will either need to be added by a team member or complete the Register to Disclose form (available from week commencing June 16) to gain access to the Portal and disclose. 

This process is essential to ensure you are linked to the right organization.     

Companies who’ve not received a request to disclose but wish to do so (ie Self-Selected Companies) should complete the Register to Disclose form too.

Public authorities who’ve not received a request to disclose by CDP Capital Markets should register to disclose as a Self-Selected Company too. Learn more about disclosing as a public authority.

If you intend to disclose, you will need to complete the following onboarding steps once you’ve signed in.

A) Confirm Submission Lead (ie the key contact point within your organization for CDP and the person who will submit your organization’s final response to the questionnaire). Your organization must confirm this to begin responding to the questionnaire and disclose.

B) Choose and pay the admin fee (if applicable). You will need to do this before you submit your response. 

C) Set up your questionnaire by answering a series of questions to determine the correct questionnaire, modules and questions applicable to you.
