Got a sustainability request from a customer?

Microsoft

Microsoft supplier reporting sits in an awkward gap: Microsoft's published disclosure-cycle guidance asks suppliers to address total-company and service-level data-integrity requirements through assurance or consultant-letter options, while the exact submission requirement still depends on the contract, portal wording, or written request you received.

CDP

A CDP supplier request usually asks your company to disclose environmental information through the CDP Portal because a buyer, investor, bank, or initiative requested it. For most mid-market suppliers, the hard part is not opening the questionnaire; it is building the emissions data, methodology, source records, and internal approvals behind the response.

EcoVadis

An EcoVadis supplier questionnaire usually asks for company-specific evidence across sustainability themes such as Environment, Labor and Human Rights, Ethics, and Sustainable Procurement. The exact questions vary by activity, size, and operating locations, so the response needs both accurate documents and a careful boundary read.
