Fair Supply turns basic spend or investment data into a full Scope 3 screening of your entire supplier base. The platform automatically classifies suppliers by industry and geography, applies emissions factors, and assigns each to the correct GHG Protocol category.

Yes. Fair Supply’s outputs are categorised in line with the GHG Protocol, which underpins many climate-related frameworks including ASRS, ISSB, TCFD, CDP, and PCAF. Fair Supply’s methodologies have undergone limited assurance, providing a defensible foundation for preparing regulator-ready disclosures.

Yes. By pinpointing emissions hotspots at supplier, industry, and geography level, Fair Supply provides the insights you need to prioritise the highest-impact areas and engage suppliers in meaningful decarbonisation strategies.

Instead of months of manual work, you can produce a complete Scope 3 screening in just weeks. Our automation makes it easy to scale across thousands of suppliers quickly and efficiently.

You only need basic supplier spend data, typically a supplier name or unique identifier and spend amount. Fair Supply uses Environmentally Extended Input-Output (EEIO) analysis to model emissions based on supplier spend, sector, geography, and economic activity across up to 10 tiers of your supply chain. No prior GHG inventory or supplier surveys are required to begin.

A Scope 3 screening is an initial assessment designed to identify which of the 15 GHG Protocol categories contribute most significantly to your emissions. It uses less specific data (such as spend-based assessments) to quickly map your emissions profile and prioritise where to focus. A full Scope 3 inventory always starts with this screening process, but it involves more granular, often supplier-specific data collection for your material categories. The GHG Protocol recommends starting with a screening to determine where more precise methods are warranted, which is exactly the process Fair Supply automates.

The GHG Protocol defines 15 Scope 3 categories split between upstream and downstream activities. Upstream categories (1–8) include purchased goods and services, capital goods, fuel- and energy-related activities, upstream transportation and distribution, waste generated in operations, business travel, employee commuting, and upstream leased assets. Downstream categories (9–15) include downstream transportation and distribution, processing of sold products, use of sold products, end-of-life treatment of sold products, downstream leased assets, franchises, and investments (also known as financed emissions). Fair Supply automatically maps your supplier data to the relevant categories.

Under Australia's mandatory climate reporting framework (AASB S2), Scope 3 emissions disclosure is subject to a one-year relief period. This means it becomes mandatory from your second reporting period. For Group 1 entities with financial years starting 1 January 2025, Scope 3 reporting will be required from the 2026/27 financial year onwards. A modified liability framework applies to Scope 3 disclosures, scenario analysis, and forward looking climate statements, recognising the inherent complexity of value chain emissions data.

Fair Supply uses Multi-Regional Input-Output (MRIO) modelling combined with EEIO analysis. This approach maps the economic relationships between industries and geographies globally, translating your procurement spend into emissions estimates across your supply chain. This includes indirect suppliers up to 10 tiers deep. This methodology is set out in the GHG Protocol's Corporate Value Chain (Scope 3) Standard as a recommended approach for screening and prioritising emission categories by magnitude.

Spend-based methods using EEIO emission factors are recognised by the GHG Protocol as a valid starting point for Scope 3 screening and are widely used by companies beginning their emissions reporting journey. While they rely on industry-average emission factors rather than supplier-specific data, they provide a defensible baseline for identifying emissions hotspots and prioritising categories. The GHG Protocol encourages a progression over time toward hybrid and supplier-specific methods for material categories. Fair Supply supports this progression by providing the screening foundation and the tools to deepen your data quality where it matters most.

Fair Supply's platform supports emissions modelling for investment portfolios, which aligns with Scope 3 Category 15 under the GHG Protocol. This is particularly relevant for financial institutions, superannuation funds, and asset owners who need to report on the emissions attributable to their investments. Fair Supply's outputs align with frameworks including PCAF (Partnership for Carbon Accounting Financials) and AASB S2, which requires disclosure of financed emissions disaggregated by scope and, in some cases, by industry and asset class.

For most organisations, Scope 3 emissions represent the majority of their total carbon footprint — often more than 70%, and in some industries exceeding 90%. Reporting only Scope 1 and 2 gives an incomplete picture of your climate impact and leaves significant risks unaddressed. Investors, regulators, and frameworks such as CDP, the ISSB standards, and Australia's ASRS increasingly expect full value chain disclosure. Organisations that engage with Scope 3 early are better positioned to set credible reduction targets, manage supply chain risk, and maintain access to ESG-focused capital.

Yes, Fair Supply is built for scale. The platform automates supplier classification, emissions factor assignment, and GHG Protocol categorisation in bulk, so you can screen your entire supplier base without manual data collection or individual supplier surveys. This makes it practical for organisations with complex, multi-tier supply chains spanning thousands of suppliers across multiple geographies and industries.

Fair Supply's Scope 3 screening methodologies have undergone independent limited assurance, which provides a level of external validation over the accuracy and reliability of the approach. This is significant because under ASRS, the assurance requirements for climate disclosures escalate over time, starting with limited assurance and progressing toward reasonable assurance by reporting periods beginning 1 July 2030. Having methodology-level assurance already in place gives organisations a stronger foundation when their own disclosures undergo external audit.
