Best supplier emissions software for 2027

Your Scope 3 sits with suppliers, and many of them will not fill in a carbon questionnaire. These tools differ on what they ask suppliers for, who pays, and how clearly they label estimates.

How to choose

1. Sends data requests to suppliers through a portal or campaign, with reminders. Ask: "How does a supplier with no login respond, and who chases them?"
2. Takes supplier-specific data: activity data, a company footprint or a product footprint. Ask: "What exactly does a supplier send: bills, a questionnaire or a footprint?"
3. Spend-based or average-data estimates for the long tail, labelled by method. Ask: "Can I see which lines are measured and which are spend estimates?"
4. Ranks suppliers and categories by emissions, so you know whom to ask first. Ask: "Which 20 suppliers should we start with, and why?"
5. A data-quality score or tier per supplier or data point. Ask: "How is each supplier’s data graded, and can our auditor see the grade?"
6. Joint targets, action plans or progress tracking with suppliers. Ask: "Can we set a target with a supplier and track it?"
7. Pulls purchase data from ERP or procurement systems; supports PACT or Catena-X. Ask: "Which ERP do you connect to today, without a custom project?"
8. Suppliers can respond without paying. Ask: "Does any supplier pay anything to respond?"
