Responding to an EcoVadis and Scope 3 data request from a European OEM

The scenario

A Tier 1 auto-components supplier in Gujarat receives a letter from a European OEM buyer stating that the next supply agreement is conditional on the supplier holding a current EcoVadis assessment and providing Scope 1, 2, and 3 emissions data in the OEM's standard template. The supplier has ISO 9001 and environmental policies on paper but no consolidated evidence file, and has never calculated Scope 3 emissions.

Approach we would model

1. Review current policies and documentation against EcoVadis's four themes — environment, labour and human rights, ethics, sustainable procurement — and identify the specific gaps: a missing supplier code of conduct and no measurable-outcome data behind the existing environmental policy, treated here as the two most common gap types for a supplier of this profile.
2. Build a Scope 1 and 2 inventory from plant energy and fuel data to support both the EcoVadis environment theme and the OEM's direct emissions data request.
3. Screen Scope 3 for materiality: purchased metal components and logistics to the OEM's assembly plant are modelled as the dominant categories, consistent with the GHG Protocol's category breakdown for component manufacturers generally.
4. Package the emissions data into the OEM's requested template separately from the EcoVadis evidence file, since the two have different structures despite drawing on the same underlying inventory.

Projected outcome

Projected / modelled — not a delivered result

Modelled outcome, not an achieved result: strengthening documentation across all four EcoVadis themes before submission is projected to move a supplier of this profile out of the lowest scoring band, based on the pattern that under-documented (rather than genuinely absent) practice is the most common driver of low EcoVadis scores. No actual EcoVadis score or contract outcome is reported here — this is a projected effect of the approach, not a measured one.
