Fair Supply's EEIO modeling provides industry-standard accuracy comparable to spend-based and average data methods recognized under the GHG Protocol. While EEIO estimates are less precise than supplier-specific primary data, they are defensible, auditable and accepted by regulators as an appropriate methodology for initial Scope 3 screening.

As you refine data quality through supplier engagement, Fair Supply supports hybrid approaches that combine EEIO with activity-based calculations for material categories to progressively improve accuracy.
