Carbon Accounting Software for Procurement and Supply Chain Teams

Scope 3 Category 1 purchased goods and services is the category that dominates most enterprise Scope 3 footprints, and it is a category many reporters find hard to defend under ASSA 5010 reasonable assurance because it leans on spend-based estimates when the activity data was in the supplier invoice all along. Procurement teams sit on the data - 200 supplier invoices a week that carry the physical quantities every AASB S2 walk-through wants to see. Carbonly is built to turn that inbound flow into a defensible Scope 3 ledger without turning your procurement team into a data-entry function.

What changes for procurement and supply chain teams

Supplier invoices you already receive flow through the AI document engine and land as emission records with activity quantities extracted - not spend proxies
Supplier Portal replaces the annual spreadsheet-to-200-suppliers questionnaire with a per-supplier authenticated surface where suppliers submit primary data, EPDs, and product spec sheets on their own cadence
Supplier Data Chase Agent tracks who has submitted and issues targeted reminders on your configured schedule instead of a broadcast email that gets ignored
Reviewer corrections saved as organisation aliases, so repeat wording on Boral, Ampol, Holcim, InfraBuild, Cleanaway, Toll, and Linfox documents matches next time
Methodology labels on every emission record - activity-based, supplier-specific, hybrid, average-data, spend-based - so AASB S2 paragraph 29(a)(vi) disaggregation is a query, not a rebuild
The 80/20 procurement engagement - your top 20 suppliers by spend on the Portal, everyone else on document extraction from their invoices

What the system does

AI reads freight invoices from Toll, Linfox, StarTrack with tonne-km extracted per consignment
AI reads construction supply invoices from Boral, Holcim, InfraBuild, BlueScope with tonnes and cubic metres extracted per delivery
AI reads waste invoices from Cleanaway, Veolia, SUEZ, Bingo with tonnes-to-landfill, tonnes-recycled, and treatment-type extracted per pickup
Supplier Portal with RBAC scoped to a single supplier - the supplier user sees only their own data, never any other supplier and never your internal ledger
Matching against a construction EPD factor library alongside NGA factors, with reviewer corrections saved as organisation aliases
Trust hierarchy scored per record: supplier-specific primary data (highest), industry-average with supplier-provided quantity (mid), spend-based EEIO (fallback)

Frequently asked

What if our top suppliers refuse to use the Supplier Portal?

The Portal is one of several access modes. Suppliers can share data via OneDrive/SharePoint folder drops, per-project email addresses your suppliers CC, and API + webhooks for the largest suppliers with their own data systems. Where a supplier legitimately does not have primary data available, the system falls back to industry-average or spend-based with the methodology label preserved on the record.

How does this handle EPDs and product carbon footprints?

Environmental Product Declarations from EPD Australasia surface alongside generic NGA factors. When a supplier provides a verified EPD, Carbonly preferences it over the regional average and flags it on the report so the auditor sees the data quality lift.

What about CBAM exposure for Australian exporters?

CBAM installation-level emissions intensity per product is stored against your supplier records, with the per-gas quantities kept so the GWP set the EU declaration calls for can be applied at the reporting layer. Data extracts feed the EU CBAM declaration; verification by an accredited third party still happens externally, but the audit trail and methodology documentation are produced by the system.
