EcoVadis Q1 2026 Methodology Updates: What Changed and What to Do About It

EcoVadis released 10 methodology changes between April and May 2026. They cover everything from how evidence coverage is calculated to the granularity of how Scope 2 emissions are reported. And they are not random adjustments. The majority trace back to EU regulatory pressure: the ESG Rating Regulation, CSDDD Annex II, and the GHG Protocol.

For sustainability teams preparing their next assessment, the question is simple: which of these changes affect you, and what do you need to do differently?

This article breaks down all 10 EcoVadis methodology updates for 2026. For each one, you get: what changed, why it matters, and what action to take.

Quick Reference: All 10 Changes at a Glance

EcoVadis Under EU Oversight: New Methodology Disclosures

What changed (effective April 1, 2026): EcoVadis published methodology disclosure documents for all products (Sustainability Rating, Carbon Rating, IQ Plus, Vitals) in a new "Regulatory disclosures" section on the platform. Three structural changes come with this:

• Major.Minor versioning across all methodologies, so every rating traces back to a specific set of rules
• A six-phase review process for methodology updates, including impact assessment and public consultation
• A 30-day public consultation for material changes expected to shift ratings for more than 10% of the collective group of companies assessed under the EcoVadis methodology

Why it matters: Regulation (EU) 2024/3005 places ESG rating providers under ESMA supervision from November 2, 2026. EcoVadis is preparing early. We covered this regulation in detail in our guide to the EU ESG Rating Regulation.

What to do: Review the disclosure document in your EcoVadis profile under "Regulatory disclosures." Understanding the scoring logic helps you prioritize where to invest effort. Sunhat consulting experts can support you in this process.

Tighter Evidence Rules: What Counts and What Doesn't

Three changes affect how EcoVadis evaluates your supporting documents. Read this section carefully if you are mid-assessment or about to start one.

Revenue No Longer Counts for Coverage

What changed (effective April 15, 2026): Relevant for L companies/Group assessments, as Site-level evidence coverage (the 80%/95% thresholds) can no longer be calculated using revenue. Coverage is now based exclusively on the number of employees or number of sites.

• Before (pre-April 15)
  
  • Evidence covers 80%+ turnover / operations / employees
• After (April 15 onward)
  
  • Evidence covers 80%+ of operations / employees only

Why it matters: A headquarters generating 60% of revenue but employing 15% of the workforce no longer counts for 60%.

What to do: Recalculate your coverage using employee count or site count before submission. If your documentation covers high-revenue but low-headcount locations, you may need to expand scope.

Broader Certification Evidence Accepted

What changed (effective April 15, 2026): If the certification standard has a public verification database (e.g., B Corp, ISO standards), you can now submit alternative evidence: database screenshots, audit reports, invoices, official communications, or website screenshots. The database must show company name, standard name, scope, and validity status.

Why it matters: Removes a common bottleneck. Companies waiting for formal certificate issuance can submit alternative proof and keep their assessment moving.

What to do: In case, you are still waiting for your certificate, but you would like to submit already, check whether your certification standards maintain public databases. If they do, prepare alternative evidence showing all four required fields as backup evidence (company name, standard name, scope, and validity status).

Audit Reports as Evidence; "In-Progress" Certificates Discontinued

Two changes in one release note, both effective April 15, 2026.

Change 1: Audit reports now count as evidence. External sustainability and certification audit reports (SMETA, amfori BSCI, TfS, qualified customer audits) are accepted for Policies, Actions, and Reporting. Coverage thresholds apply: 80% for Policy/Reporting, 95% for Energy/GHG KPIs.

Change 2: "In-progress" certificates are no longer accepted. ISO 14001, 45001, 27001 and similar certificates marked "in-progress" no longer receive scoring credit.

What to do:

• If you have qualifying audit reports: prepare them as evidence across Policies, Actions, and Reporting
• If you relied on in-progress certificates: accelerate your certification timeline or identify which audit reports can fill the gap
• Watch out: Audit reports with major non-conformities can backfire. EcoVadis may decline to award points or reflect findings negatively in 360 Watch

Reporting and Scoring: Higher Standards, Clearer Rewards

GRI "With Reference" Now Scores 75

What changed (effective April 14, 2026): GRI "with reference" disclosures are now eligible for a reporting score of 75 out of 100, provided other quality criteria are met. Previously, this only triggered a strength. Now it directly lifts your reporting score.

Why it matters: Companies do not need full "in accordance" compliance to benefit. This lowers the barrier to GRI adoption for EcoVadis purposes.

What to do: If you already report with GRI "with reference," make sure your submission highlights this clearly.

Granular Scorecard Feedback Replaces Vague Improvement Areas

What changed (effective April 15, 2026): Vague improvement areas are replaced with diagnostic feedback across four categories:

1. Sector best practices: Missing environmental actions flagged against sector benchmarks
2. Policy robustness: Alerts when quantitative targets are absent from policies (Environment + Labor)
3. Endorsement quality: Distinguishes voluntary pledges from robust, sector-specific initiatives
4. Certification gaps: Explicit flags for missing ISO 27001 or ISO 37001

Important: The underlying scoring methodology has not changed. This only changes how feedback is displayed.

What to do: When your next scorecard arrives, review the new Improvement Areas as a diagnostic checklist. These are the clearest indicators of where points are available.

Our sustainability experts analyze your previous scorecard against learnings from 1,000+ successful assessments.

Environmental Criteria: Carbon, Biodiversity, and Risk Preparedness

Three changes affect the Environment theme. Two align EcoVadis criteria with EU regulation. One introduces a scoring opportunity most companies will overlook.

CSDDD Annex II Alignment in Biodiversity, Air Pollution, and Waste

What changed (effective April 15, 2026): EcoVadis reworded and expanded options under Biodiversity, Air Pollution, and Materials/Chemicals/Waste to match CSDDD Annex II environmental prohibitions. A new option, "Actions to prevent offshore waste discharge," was added. Existing options were rephrased for clarity.

Why it matters: EcoVadis is mapping environmental criteria directly to EU due diligence law. Companies preparing for CSDDD can use their assessment as a readiness check.

What to do: Read the updated Help Content for these questions. The reworded options may apply to actions you already take but describe differently.

New Environmental Risk Preparedness Questions

What changed (effective April 15, 2026): Two new questions assess how companies manage external environmental disruptions. Question 1 covers risk assessments (physical climate risk, water basin risk, biodiversity dependency; options vary by industry). Question 2 covers response actions (adaptive practices, emergency reserves, dedicated budgets; options vary by company size).

Scoring: These questions do not negatively impact your score. But valid evidence can trigger new Strengths. Pure upside opportunity.

What to do: If you have physical climate risk assessments, water basin analyses, or documented resilience measures, prepare them as evidence. These are easy strengths to leave on the table.

Scope 2 Emissions: Location-Based and Market-Based Split

What changed (effective May 7, 2026): The single "Total gross Scope 2 GHG emissions" metric is replaced by two options: location-based (average grid emission factor) and market-based (your specific energy procurement choices). No direct scoring impact.

Why it matters: Aligns with the GHG Protocol. Companies already reporting both figures for CSRD or CDP can reuse the same data.

What to do: Check whether your GHG inventory already separates location-based and market-based Scope 2. If not, coordinate with your carbon accounting team ahead of the May 7 rollout.

Scorecard Pre-Publication Review: A Two-Day Window

What changed (rolling out Q2 2026): Rated companies now get a two-business-day window to review their scorecard before it publishes to the network. You can report factual errors during this period. The scorecard auto-publishes after two days, even if a reported error is still under review.

What qualifies: Wrong company name/size/industry/location, a 360 Watch item that does not belong to your entity, or a document rejected despite meeting requirements.

What does not qualify: Disagreement with your score, EcoVadis's judgment, or methodology weightings.

What to do: Two days is not enough time to build a case from scratch. Maintain a clear record of every document submitted, every question answered, and every 360 Watch item tied to your legal entity. When the scorecard arrives, compare systematically.

What the Q1 2026 EcoVadis Methodology Updates Signal

Seven of these ten changes trace directly to EU regulatory requirements. EcoVadis is adapting its methodology to ensure it continues to function as a credible, regulated rating under ESMA oversight and to support the trend of European regulations that will promote greater sustainability across industries.

The evidence quality trend is equally clear. Revenue removed from coverage. In-progress certificates discontinued. Audit reports formalized. Certification evidence expanded but with strict technical requirements. The bar for what counts as proof is going up, while the number of ways to meet it is growing.
