• EcoVadis and CO2 AI are integrating supplier-level carbon data with corporate emissions accounting to reduce reliance on spend-based Scope 3 estimates.
• The partnership gives procurement and sustainability teams access to company-level emissions data and product carbon footprints inside CO2 AI’s footprinting platform.
• The companies say the integration can strengthen supplier intervention strategies, net-zero tracking and audit-ready Scope 3 reporting.

EcoVadis and CO2 AI have partnered to give companies more direct access to supplier emissions data as pressure builds for higher-quality Scope 3 reporting.

The collaboration connects EcoVadis’ supplier carbon ratings and primary emissions data with CO2 AI’s footprinting engine. Mutual customers will be able to use supplier-specific information instead of relying primarily on industry averages or spend-based estimates.

For companies with complex value chains, that shift could materially change how they manage purchased goods and services emissions. Scope 3 frequently accounts for the majority of a company’s total carbon footprint. Yet data quality remains one of the biggest barriers to credible measurement and reduction strategies.

Moving Scope 3 beyond estimates

Many companies still calculate substantial portions of their Scope 3 inventories using financial spend or sector-average emissions factors.

Those methods can establish a baseline, but they provide limited visibility into individual supplier performance. They can also make it difficult to determine whether procurement decisions are producing measurable emissions reductions.

EcoVadis and CO2 AI aim to close that gap by connecting supplier data directly with corporate carbon accounting workflows.

Customers can access specific supplier carbon metrics, track performance against decarbonization plans and integrate primary data into reporting systems. The companies also expect the system to help identify suppliers where intervention could deliver the greatest emissions reductions.

“Our partnership with CO2 AI is a vital step in transforming global supply chains from sources of risk into drivers of climate resilience,” said Dexter Galvin, SVP Climate at EcoVadis. “By combining our reliable supplier network with advanced AI modeling, we are empowering companies to move from estimation to action.”

Procurement becomes a carbon data hub

The partnership forms part of EcoVadis’ wider Carbon Data Network initiative. The network is designed to connect supplier emissions information with the companies responsible for calculating and managing Scope 3 inventories.

It sits within EcoVadis’ Carbon Action Manager offering, which also includes a Product Carbon Footprint Calculator. Suppliers can contribute emissions information while accessing tools for collaboration and carbon capability development.

The integration with CO2 AI brings that information into a footprinting environment where companies can combine corporate-level and product-level supplier data.

“Procurement teams have long been held back by the quality of their Scope 3 data “ said Charlotte Degot, CEO and co-founder at CO2 AI. “By combining EcoVadis’ supplier network with CO2 AI’s footprinting engine, we’re giving companies the granularity they need to move from compliance reporting to real decarbonization progress.”

The model places procurement teams closer to the centre of corporate climate governance. Supplier selection, engagement and contract management increasingly determine whether companies can translate climate targets into measurable value-chain reductions.

Primary data strengthens reporting controls

EcoVadis and CO2 AI highlighted a global hospitality group that uses both platforms. The company needs primary emissions information from strategic suppliers to assess progress against supplier decarbonization goals.

Under the new integration, supplier company data and primary emissions information collected through EcoVadis can flow directly into CO2 AI.

That creates a single workflow for different levels of emissions granularity. Corporate emissions data and product carbon footprints can enter the same footprinting system without separate manual processes.

Companies can then replace selected secondary estimates with supplier-specific information and track changes in supplier performance over time.

For reporting teams, the governance implications extend beyond improved carbon calculations. More traceable primary data can strengthen internal controls, support audit processes and provide clearer evidence behind emissions disclosures.

It can also help companies distinguish between suppliers that are actively reducing emissions and those where progress remains limited.

What executives and investors should watch

Better Scope 3 data does not automatically produce decarbonization. Companies still need procurement incentives, supplier engagement, capital allocation and credible transition plans.

However, primary supplier information can give management teams a stronger basis for making those decisions. It also reduces dependence on broad assumptions that can obscure where emissions risks actually sit within a supply chain.

For investors, lenders and corporate boards, that matters as value-chain emissions become increasingly connected to transition planning, disclosure quality and climate-related risk management.

The EcoVadis and CO2 AI partnership reflects a wider shift in corporate carbon accounting. Scope 3 reporting is moving from estimation toward supplier-specific evidence, while procurement systems are becoming part of the climate data infrastructure.

As disclosure expectations mature globally, the quality of that underlying data will increasingly determine whether corporate climate claims can withstand scrutiny.
