EcoVadis now asks for Scope 2 location-based and market-based. What changed?

From 7 May 2026, EcoVadis replaced its single Scope 2 field with two: total location-based and total market-based Scope 2. The scoring weight did not change, but strengths, improvement areas and data reliability now follow the evidence behind each figure, so report both, with documents.

What changed in the questionnaire

• Removed: Total gross Scope 2 GHG emissions (market- or location-based).
• Added: Total gross location-based Scope 2 GHG emissions.
• Added: Total gross market-based Scope 2 GHG emissions.
• Applies to the Sustainability Rating and the Carbon Action Manager, for small, medium, large and extra-large companies.
• EcoVadis says the scoring impact is unchanged, but each figure now gets its own reliability level: Low, Medium, High or Third-Party Verified.

Working out each figure in India

• Location-based: all grid kWh you consumed x the CEA grid factor for that financial year, 0.675 kg CO2 per kWh for FY 2025-26.
• Market-based: kWh covered by contracts or certificates you can prove, such as retired renewable energy certificates, a green tariff or a renewable open access supply, at their own factor. The rest at a residual mix factor if one is available; otherwise the grid factor, stated as such.
• Rooftop solar you generate and use yourself is not bought electricity. It lowers grid kWh in both figures, and is not a certificate to count again.
• No green contracts at all: both figures come out the same. Report both anyway and say why they match.

Evidence to attach for each

1. Location-based: the year's electricity bills for every connection, and the factor with its source.
2. Market-based: certificate retirement statements, green tariff bills or open access invoices for the exact kWh you claim, matching the reporting year.
3. A short note of the method: which kWh were covered by what, and which factor the rest used.

• Grid electricity FY 2025-26: 12,00,000 kWh.
• Location-based: 12,00,000 x 0.675 = 8,10,000 kg = 810 t CO2.
• Certificates retired for 4,00,000 kWh, counted at zero.
• Remaining 8,00,000 kWh at the grid factor, stated as such: 8,00,000 x 0.675 = 5,40,000 kg = 540 t CO2.
• Enter 810 t as location-based and 540 t as market-based, with bills and retirement statements attached.

Quantities are invented. Check your buyer accepts the certificate type before counting it.

What Senseible does here

Senseible reports location-based Scope 2 from your electricity bills and market-based Scope 2 when you add your certificate or green tariff records, so both EcoVadis fields come from the same documents.
