Question

What is the model used for score calculation, including indicator weights and Coverage?

EcoVadis does not publicly disclose its exact formula, but the structure is well understood. The system first determines your scope from your Activated Criteria — the topics material to your company, defined by sector classification, size and geographic operating risk. Analysts independently review the evidence and assign scores across the PAR framework; theme scores are calculated from indicator scores, weighted by materiality, and the overall score is a weighted average of the four theme scores — a chemical manufacturer and a professional-services firm have different theme weightings. The result is recalibrated against the global database to produce your percentile and medal.

The confirmed indicator weights as a share of the overall score: Policies 20%, Endorsements 5%, Measures 24%, Certifications 16%, Reporting 14%, 360° Watch 21% — sitting within three categories: Policies 25%, Actions 40%, Results 35%.

Coverage is not assigned a fixed percentage: it functions as a multiplying factor applied to the Measures and Certifications scores, reflecting how widely those practices are deployed across the group. High Coverage amplifies strong results; low Coverage diminishes them. Changes to your sector, size or scope can alter both the activated criteria and the weightings.
