How to answer a customer ESG questionnaire
A practical guide for small suppliers responding to customer sustainability and ESG requests.
Summary
Start by understanding what the buyer is asking for, then gather evidence and review the answer before sending.
Audience: Small B2B suppliers. Risk level: medium.
Decode before drafting
Separate the request into topics, evidence needs, deadline, and review risks before writing customer-facing answers.
Use evidence you can defend
Policies, records, calculations, and owner-approved notes are stronger than vague commitments.
Avoid overclaiming
If something is estimated, partial, or not yet reviewed, mark it clearly and decide whether it belongs in the final response.
Source basis
Regulatory or legal conclusions should be reviewed against current official sources before being used externally.
