Scope 3 Supplier Emissions Questionnaire

An Excel questionnaire toolkit for collecting emissions data from suppliers. Covers the key data points needed to begin building a Scope 3 supplier emissions inventory, structured to reduce back-and-forth with suppliers and improve data consistency.

Helps you standardize how you request and collect emissions information from suppliers, as a starting point for measuring value chain emissions.

Best for sustainability teams beginning supplier emissions data collection, or companies looking for a lightweight way to gather Scope 3 data before investing in dedicated software. The methodology is standard GHG Protocol, so it transfers well across frameworks. Some terminology references Australian reporting standards and may need light adaptation for EU contexts.
