Value chain reporting
For Scope 3 and other value chain data, CSRD allows “reasonable effort” in data collection — you don’t need 100% supplier response rates. Best practice:- Aim for coverage of >80% of spend for Category 1 Scope 3
- Use estimation for small/long-tail suppliers (Matproof handles this with spend-based method)
- Document your methodology and coverage rates (required disclosure)
