What did EcoVadis Sustain 2026 teach us? Field notes from the conference

In brief

Attended live by ESGIM (March 2026), the Sustain conference confirmed a shift: sustainability is moving from awareness creation to execution. EcoVadis framed it as four pillars of sustained advantage — resilience (securing critical resources, spotting early signals), innovation (new growth models; mining carbon data with AI revealed supply-chain emissions 21× higher than direct emissions), intelligence (anticipating risks; integrations with Amazon Business, Microsoft, Moody's) and trust ("trust is the multiplier": turning data into action with consulting partners such as SGS and Schneider Electric).

What did the keynotes say?

Helena Helmersson (ex-CEO H&M): perspective creates clarity — she plots sustainability on the Gartner Hype Cycle, and adds an exponential curve on top of it: impact.

Bertrand Conquéret (Henkel): the Together for Sustainability (TfS) initiative as the chemicals sector's common language.

John Morrisson (human rights): child labour has come down; AI now helps understand which legislation will work; watch the social cost of data centres — workers, communities, social consensus. The circular economy (second-hand, long cycles) cannot carry a negative human rights tag.

Paul Polman (ex-CEO Unilever): it goes very fast — unlearn and learn again. The green economy is worth $5T, expected to grow to $7T — the second growth sector; companies with over 50% green revenues attracted valuations 12-15% higher. Four forces are redefining operating models: geopolitics (produce where it is safest — key topic, only 2% implemented), climate & nature risks (the cost of acting is lower than the cost of not acting), AI, and regulation — the three-directional current (USA, China, EU), where Omnibus pushes obligations to the private sector: if a large company committed to Scope 3 reduction, suppliers will have to come along. 92% of companies have not stopped their net zero goals. Only 5% of CEOs can measure the ROI of sustainability; what we miss is leadership.

What is EcoVadis' strategy: trust at scale, AI-first?

The bottleneck in AI is trusted data — 60% of AI projects will be abandoned because of poor data quality. EcoVadis' answer is three filters: the global network, human verification, and worker-level insight (18M+ workers' data through worker-voice surveys — visibility beyond self-reported data). The strategy: unlock the power of unique data with AI — one unified platform to uncover hidden risk, agent-assisted workflows with human-led resolution, and a connected ecosystem. Concretely for rated companies: AI-powered document verification and outlier detection, document eligibility checks, and suggested answers based on the documents you have uploaded — a direct answer to questionnaire fatigue. Product-level data remains rare: only 6% of companies can produce it.

How does Schneider Electric run its procurement?

Schneider Electric combines on-site audits with EcoVadis ratings for strategic suppliers, focused on improvement — supplier emissions are 40× its own Scope 1 & 2, and it assesses the carbon emissions of its 1,000 largest suppliers. The method: meet suppliers where they are; set achievable targets; provide support. Not imposing targets: on living wage, chapter 1 asked suppliers to have a policy; chapter 2 asks them to measure the gap and build a roadmap. Five years ago many suppliers didn't know what carbon accounting was; now they can talk about Scope 3. One tip passed on: start every negotiation with sustainability.

What does the Sustainable Procurement Barometer reveal?

Capability is growing but hasn't caught up with ambition (EcoVadis & Accenture): 48% of buyers have visibility on 75%+ of Tier 1 suppliers, versus 10% for half of Tier 2 — Tier 3 is a black box. Two out of three organisations already collect product-level carbon data; 30% have fully integrated sustainability into procurement processes; just 17% of suppliers feel strongly motivated by their customers. Seven in ten cite unclear ROI, supplier data and competing priorities as the top barriers. The key to unlock value? It's not ambition. It's integration: goals × incentives, data × decisions, investment × priorities, narrative × reality.

What does the Siemens Gamesa case prove?

Siemens Gamesa tested the hypothesis of a negative relationship between EcoVadis performance and supplier quality costs. Finding: higher EcoVadis scores correlate with lower quality costs — sustainability creates financial value. The effect is strongest for Environment and Sustainable Procurement, weaker but visible for Labor & Human Rights and Ethics. EcoVadis becomes an early, actionable signal for supplier selection and improvement. Related signals: an SBTi commitment is a preferred-supplier criterion at AstraZeneca; Amazon Business now shows a green score on product selections; steel is already carbon-priced via ETS in Europe or CBAM at the border.

Key takeaways

• Sustainability has moved from awareness to execution; resilience is the new sustainability.
• The green economy is a growth story ($5T → $7T) — and 92% of companies keep their net zero goals despite the noise.
• The EcoVadis platform is turning AI-first: document checks, suggested answers, outlier detection — cleaner submissions win.
• Large buyers engage suppliers progressively (Schneider Electric's chapters) — but Tier 3 visibility is a black box, and only 17% of suppliers feel motivated.
• A better EcoVadis score correlates with lower quality costs (Siemens Gamesa): the medal is not just compliance, it is a commercial signal.
