EcoVadis’ latest Sustainability Ratings Index — based on nearly 200,000 scorecards across 100,000+ companies rated from 2021–2025 — reveals that 80% of firms lack documented ESG supply chain strategies. Critical gaps include 73% without Scope 3 upstream emissions reporting, 77% lacking downstream tracking, and only 2% operating functional external grievance mechanisms. Just 20% conduct on-site audits, while 42% rely on unverified supplier questionnaires. Among corporate buyers, 68% use AI in sustainable procurement, yet 30% of suppliers provide no carbon data — highlighting a systemic data readiness shortfall threatening ESG tech ROI.
According to supplychaindigital.com, EcoVadis has found that 80% of companies globally have no documented process for identifying or managing sustainability risks within their supply chains.
Widespread Documentation Gaps Undermine ESG Efforts
The findings come from the latest edition of the EcoVadis Sustainability Ratings Index, which draws on nearly 200,000 scorecards issued to more than 100,000 companies rated globally between 2021 and 2025. The index reveals a systemic documentation crisis: 77% of firms lack downstream tracking of Scope 3 emissions, while 73% report no upstream Scope 3 emissions data — a critical gap given that supply chains represent the largest opportunity for sustainability breakthroughs, per McKinsey analysis.
Further exposing transparency deficits, 98% of rated companies do not maintain an external grievance mechanism accessible to workers deeper in the supply chain. Only 2% operate such mechanisms that are actually usable by those workers to flag human rights violations. Meanwhile, less than 1% provide granular, decision-grade sustainability data to buyer organizations — severely limiting procurement teams’ ability to act on verified insights.
Verification Relies Heavily on Unverified Inputs
EcoVadis reports that 42% of companies rely solely on unverified supplier questionnaires for sustainability assessments. Only 46% require suppliers to sign a formal sustainability code of conduct, and just 20% conduct on-site audits — raising serious questions about the fidelity of self-reported data across tiers. Without physical verification, companies risk operating with incomplete or inaccurate understanding of labor conditions, environmental practices, and operational realities at supplier facilities.
“Companies willing to treat supplier engagement as an ongoing process, rather than a one-time compliance exercise, close the distance between what they intend and what they can actually verify.” — Sylvain Guyoton, Chief Rating Officer at EcoVadis
AI Adoption Confronts Data Readiness Shortfalls
As corporate buyers accelerate AI deployment for sustainability reporting, data gaps in the supplier base are stalling progress. EcoVadis data shows 68% of corporate buyers have deployed AI tools in sustainable procurement programs, with carbon data validation cited as the top application by 62% of them. Yet only 30% of suppliers provide any carbon data at all, and 26% supply only aggregated estimates — insufficient for AI models requiring standardized, tiered, and auditable inputs.
This mismatch underscores a fundamental misalignment: while The Boston Consulting Group reports that 44% of companies are deploying AI in supply chain management — a higher adoption rate than in finance, HR, or procurement — technology alone cannot resolve structural data deficiencies. As Sylvain Guyoton notes: “Better software does not close that gap. The measurement problem lives in the supply base itself, and closing it requires sustained engagement over time: structured assessment, scored performance and documented follow-through.”
Strategic Implications for Procurement Teams
For supply chain professionals, these findings signal urgent operational implications. Without documented risk processes, verified supplier data, or functional grievance channels, ESG due diligence remains performative rather than actionable. Practitioners must shift from point-in-time audits to continuous, collaborative capacity-building — embedding sustainability requirements into contract terms, co-developing supplier reporting templates, and investing in tier-2 and tier-3 data collection infrastructure. The July 12, 2026 publication date of this analysis coincides with tightening regulatory timelines under frameworks like the EU’s Corporate Sustainability Due Diligence Directive (CSDDD), making remediation no longer optional but legally imperative.
