VERIFIED EMISSION FACTORS FOR CREDIBLE SCOPE 3 INVENTORIES

Move beyond industry averages with independently verified, supplier-specific emission factors. SustainCERT verifies the methodologies and emissions data behind emission factors, helping organizations improve the accuracy and credibility of their Scope 3 greenhouse gas inventories.

Move beyond industry-average emission factors

Emission factors are fundamental to calculating Scope 3 emissions. They translate business activity, such as the quantity of a material purchased, into the greenhouse gas emissions associated with that activity.

Many organizations rely on generic emission factors from industry or national databases. While these provide a useful starting point, they may not reflect actual sourcing locations, productions conditions, or differences in supplier performance.

Supplier-specific emission factors use primary data to provide a more representative picture of emissions across the value chain. Independent verification provides assurance over how these emission factors have been calculated and the data behind them, increasing confidence in the results used for Scope 3 reporting.

Improve emission data accuracy

Replace generic assumptions with supplier-specific emissions data that better reflects actual production conditions.

Capture supplier performance

Track changes in emissions intensity over time and reflect improvements made by suppliers across your value chain.

Strengthen reporting credibility

Use independently verified emission factors to support Scope 3 reporting and increase confidence in reported emissions data.

Independent Emission Factor Verification

SustainCERT independently verifies supplier-specific emission factors using an inventory accounting approach aligned with the GHG Protocol.

Our auditors assess how emission factors have been developed, from the calculation methodology and system boundaries to the underlying activity data, emissions calculations, and supporting evidence.

Emission factors can represent a specific production site, sourcing location, supply shed, or broader supplier group. Verification provides independent assurance that the emission factor has been calculated in accordance with the applicable accounting requirements and accurately represents the defined scope.

What we verify

Our verification assesses whether the methodology, data, and calculations underpinning an emission factor meet the applicable GHG accounting requirements.

Methodology
We review the calculation methodology, system boundaries, reporting period, and functional unit to confirm that the emission factor has been developed using an appropriate inventory accounting methodology.

Emissions data
We assess underlying activity data, emission calculations, allocation methods, and supporting documentation to confirm that reported values are accurate and supported by evidence.

Verification outcome
Following successful verification, clients receive an independent verification statement documenting the scope, criteria, level of assurance, and outcome of the assessment.

Issue Emission Factor Units on the Carbon Management Platform

Once verified, emission factors can be managed on the SustainCERT Carbon Management Platform.

The Platform provides a centralized system to manage verified and unverified Scope 3 data. Organizations can issue Emission Factor Units, transfer emissions data across the value chain, and generate reporting-ready outputs for Scope 3 inventories. Built-in safeguards help manage claims while providing transparency over how emissions data is shared and used.

Regrow

Policy and Programs Protocol Manager

SustainCERT’s validation gives companies confidence that Regrow can underpin high-integrity climate claims. This pre-validated methodology streamlines the path to assurance, accelerates trust, and demonstrates scientific rigor. This is especially important now, as removals become a critical lever for managing climate risk.

Crop Intellect Ltd

CEO

Validation with SustainCERT is a significant achievement for Crop Intellect’s team and a step forward for agriculture. For the first time, multinationals can validate a GHG removal within their own supply chains—wherever crops are grown—while supporting growers with a practical intervention that combines nitrogen reduction and direct N₂O removal.

Indigo Ag

VP, Sustainability Solutions

With growing scrutiny in the market, companies need assurance that the projects they invest in align with relevant standards and maintain high quality – which we felt SustainCERT’s audit allowed us to do.
