Carbon Emissions Accounting Software

Most organisations can produce their first Scope 1 and 2 emissions estimate within minutes using Fair Supply's guided calculator. For Scope 3 emissions, you can generate a complete Scope 3 emissions report by category within weeks by simply uploading basic supplier spend data.

Our technology automatically classifies suppliers by industry and geography, applies unique emissions factors to each tier of the supply chain, and assigns each supplier to the correct GHG Protocol category without manual data collection.

Yes. Fair Supply uses Environmentally Extended Input-Output (EEIO) modeling to estimate Scope 3 emissions based on supplier spend, sector, geography and economic activity across up to 10 tiers. This allows you to produce a defensible Scope 3 screening immediately, then refine data quality over time as you engage suppliers and collect primary data. It's the fastest way to move from zero visibility to a complete baseline.

Fair Supply provides an immutable audit trail that tracks every data input, calculation methodology and emissions factor used in your reporting. The platform's outputs are mapped to the GHG Protocol and aligned with frameworks like ASRS, ISSB, CDP and CSRD.

Fair Supply's Scope 3 methodologies have undergone independent limited assurance, giving auditors confidence in the defensibility of the approach without requiring you to validate methods from scratch each reporting cycle.

Yes. Fair Supply's carbon emissions accounting software is purpose-built to support compliance with AASB S2 Climate-related Disclosures under the Australian Sustainability Reporting Standards.

The platform enables you to measure Scope 1, 2 and 3 emissions, maintain audit-ready documentation, and produce regulator-ready disclosures aligned to the four core pillars of governance, strategy, risk management, and metrics and targets required by ASRS.

A Scope 3 screening uses automated EEIO modeling to rapidly assess emissions across your entire supplier base, identify hotspots, and prioritize where deeper engagement is needed. A full Scope 3 inventory involves collecting primary data from suppliers and applying activity-based calculations for each category.

Fair Supply supports both: start with automated screening to establish a defensible baseline quickly, then progressively refine material categories into a detailed inventory with supplier engagement and expert support.

Fair Supply's EEIO analysis models emissions across up to 10 tiers of your supply chain, not just your direct suppliers. This is critical because emissions often accumulate deep in the value chain — across raw materials, component manufacturing and logistics providers.

The platform maps spend data to supplier location and industry, then calculates embodied emissions across multiple tiers to give you full visibility into where carbon risk actually sits in your extended supply chain.

Yes. Fair Supply includes built-in supplier engagement tools that allow you to launch emissions-focused Self Assessment Questionnaires (SAQs), track supplier responses, benchmark supplier performance against peers, and update mitigation plans — without manually chasing suppliers.

This moves you from estimated EEIO data toward primary supplier-reported emissions data while maintaining workflow efficiency and audit traceability.

Under mandatory climate reporting in Australia, Scope 3 disclosure requirements are phased in: Group 1 entities must report Scope 3 from January 2026, Group 2 from July 2027, and Group 3 from July 2028.

Fair Supply's automated screening means you can establish a compliant Scope 3 baseline immediately rather than waiting months for manual data collection, giving you a critical head start on meeting your reporting obligations and avoiding last-minute compliance pressure.

Fair Supply's EEIO modeling provides industry-standard accuracy comparable to spend-based and average data methods recognized under the GHG Protocol. While EEIO estimates are less precise than supplier-specific primary data, they are defensible, auditable and accepted by regulators as an appropriate methodology for initial Scope 3 screening.

As you refine data quality through supplier engagement, Fair Supply supports hybrid approaches that combine EEIO with activity-based calculations for material categories to progressively improve accuracy.

Fair Supply is designed to work with the tools you already manage. The platform accepts spend data from standard formats (CSV, Excel) exported from ERP, procurement or AP systems — there's no requirement to replace existing systems.

Once data is uploaded, Fair Supply automates classification, emissions factor assignment and GHG categorization, then produces outputs that feed directly into sustainability reports, ESG disclosures or climate risk assessments without disrupting current workflows.

Spreadsheets require manual supplier classification, manual research of emissions factors, manual GHG category assignment, and manual calculations repeated for every supplier across every reporting period. Fair Supply automates all of this at scale.

What would take months of manual work across thousands of suppliers happens in weeks with automated classification and audit-ready outputs. You also avoid version control issues, formula errors and the lack of traceability that make spreadsheet-based reporting difficult to audit and impossible to scale efficiently.

Yes. Fair Supply provides the emissions data and supplier risk insights that underpin climate scenario analysis and resilience assessments required under AASB S2.

By identifying emissions hotspots by supplier, geography and industry, you can model exposure under different climate scenarios — physical risks, transition risks, carbon pricing — and assess the resilience of your supply chain and business model. Fair Supply's advisory team also supports organisations in structuring scenario analysis frameworks aligned to ASRS and TCFD disclosure expectations.

Fair Supply combines technology with human expertise. While the platform automates the heavy lifting of supplier classification, emissions calculations and GHG categorization, our team of carbon accounting specialists provides hands-on consulting for the complex parts that software alone can't solve.

This includes designing bespoke methodologies for unusual emissions categories, advising on materiality assessments and boundary setting, supporting climate scenario analysis and resilience disclosures, preparing for auditor queries, and building internal capability across finance, sustainability and procurement teams.

This hybrid approach means you get the speed and scale of automation with the judgment and defensibility that comes from experienced advisors who understand both the technical requirements and the regulatory context.

Fair Supply provides both a Scope 1 and 2 Emissions Calculator and a Scope 3 Supply Chain Assessment using EEIO modeling.

Yes. Fair Supply provides guided calculators to help organisations estimate and report their Scope 1 (direct) and Scope 2 (energy-related) emissions. The outputs align with leading frameworks like the GHG Protocol, CDP, IFRS S2, and ESRS, making them suitable for formal audits, disclosures, and internal climate targets.

Fair Supply uses Environmentally Extended Input-Output (EEIO) analysis to model Scope 3 emissions based on supplier spend, sector, geography, and economic activity across up to 10 tiers.
