Frequently Asked Questions

What are the requirements for the annual Communication on Progress reports?

Mandate endorsing companies have quite a bit of flexibility in how they report progress. The only requirements is that they speak toward their progress against all six commitment areas: 1) Direct Operations, 2) Supply Chain & Watershed Management, 3) Collective Action, 4) Public Policy, 5) Community Engagement, and 6) Transparency. Companies are encouraged to use the Mandate’s Corporate Water Disclosure Guidelines as a guiding framework for their reporting. Companies are also welcome to submit their CDP Water Questionnaire to fully meet their reporting requirement for the Mandate.


What if my company is not currently a signatory of the UN Global Compact?

New endorsing companies are given a one-year grace period to become signatories of the UN Global Compact. After that, they will be removed as Mandate endorsers. To learn more about becoming a UN Global Compact signatory, go to:
