Short answer
Scope 3 assurance is an independent check on how your value chain emissions were calculated, where the data came from, and whether the methodology is sound.
What assurance providers look for
Traceable source data, consistent methodology, version control and a clear audit trail for supplier specific numbers.
How to make assurance easier
Keep evidence with every number. Document methodology and changes. Use supplier specific data where it materially shifts the answer.
