Stop Asking Suppliers for Data. Start Helping Them Decarbonise.

The Questionnaire Trap

A common Scope 3 journey begins with a supplier questionnaire. Please report your emissions. Please describe your target. Please complete this platform. Please provide product data.

Measurement matters. The GHG Protocol encourages companies to obtain primary information from relevant value-chain partners where appropriate. But data collection can easily become the programme rather than the beginning of the programme.

If a supplier completes a perfect inventory and changes nothing operationally, the customer's reporting may improve while the atmosphere notices no difference.

Understand the Supplier Reality

Suppliers are not a homogeneous audience. A global strategic supplier may have a sophisticated climate team. A small regional business may not know the difference between Scope 1 and Scope 2. One supplier may lack data. Another knows exactly what to do but cannot finance the capital. Another may see no business case because customers are unwilling to pay or commit demand.

Effective engagement begins with empathy for the supplier's constraints. What capability, certainty, technology, finance or commercial signal would make action rational?

Segment the Challenge

Supplier programmes improve when companies prioritise rather than broadcast the same request to everyone. Segment by emissions significance, spend, strategic importance, readiness and ability to influence.

High-emitting strategic suppliers might warrant one-to-one transition plans. Mid-tier suppliers may benefit from common training, templates and group purchasing. Smaller suppliers may need simplified measurement tools. Innovation-intensive categories may require co-development rather than standard compliance.

Segmentation makes collaboration proportionate to both the emissions opportunity and the relationship.

Build an Engagement Ladder

A useful progression is: Inform -> Measure -> Educate -> Enable -> Incentivise -> Innovate together.

Inform suppliers why the issue matters. Help them measure enough to identify priorities. Build capability where knowledge is missing. Enable action with tools, technical support or access to solutions. Use procurement incentives and longer-term signals where economics matter. Then create mechanisms for joint innovation when existing options are insufficient.

Not every supplier needs every stage. The ladder is a way to move from extracting information toward building capability.

Make Decarbonisation Mutually Valuable

The strongest supplier engagement does not ask partners to decarbonise solely for the customer's target. It looks for shared value: lower energy costs, improved efficiency, reduced material use, stronger customer relationships, access to finance, product innovation and greater resilience.

That does not remove hard trade-offs. Some transitions cost money and require customers to make different purchasing choices. But it changes the relationship from compliance request to joint problem-solving.

The question becomes: what conditions would make the lower-emissions choice possible for both of us? That is a much more collaborative question than "Please send us your data by Friday."
