Scope 3 supplier data

Spend based data uses industry averages to estimate emissions from how much you spend. It is fast to get started with but blunt: every supplier in a category looks the same.

Supplier specific data (also called primary supplier data) comes from the supplier or their public disclosures. It is more accurate, more useful for decisions, and stands up better under assurance. It is what SBTi v2 is steering Category A companies towards.

Public disclosures, CDP responses, sustainability reports, supplier portals and direct supplier engagement. DitchCarbon brings these signals together for supplier level Scope 3 readiness.

Start with the suppliers behind the largest share of your Scope 3. Use public disclosures first and engage suppliers only for the gaps that materially change the answer.

Keep a clear record of source, methodology and any estimation alongside every number. That record is what makes the data assurance ready and what makes year on year comparisons meaningful.
