Carbon Accounting
A defensible carbon footprint across Scope 1, 2 and 3 - governed, auditable, and refreshed automatically.
A managed carbon accounting capability built on Microsoft Sustainability Manager that consolidates Scope 1, 2 and 3 emissions with the right methodology and emission factors, replaces fragile spreadsheets with a governed data model, and keeps your footprint audit-ready all year.
Carbon accounting that survives an audit
Most carbon footprints live in a spreadsheet that one person understands. Factors go stale, methodology is inconsistent, restatements are painful, and every audit re-opens the same questions. As emissions data moves from a voluntary nice-to-have to an assured financial disclosure, the spreadsheet stops being good enough.
We build carbon accounting on Microsoft Sustainability Manager: a governed data model with the correct activity-based and spend-based methodologies, a maintained emission-factor library, automated data ingestion, and full restatement history. Your footprint becomes a repeatable, auditable process instead of an annual scramble.
Scope 1, 2 & 3 model
A complete emissions model with activity-based and spend-based methods applied correctly to each category.
- Location and market-based Scope 2
- Activity and spend-based Scope 3
- Category-appropriate methodology
Maintained factor library
NGER, GHG Protocol and market factors kept current, so your footprint does not silently drift out of date.
- NGER factor sets
- GHG Protocol alignment
- Annual factor refresh
Automated ingestion
Connectors pull utility, fleet, travel and finance data in, replacing manual re-keying and copy-paste errors.
- Utility bill ingestion
- Travel and expense feeds
- Finance and procurement data
Restatement & audit trail
Version history and data lineage on every figure, so restatements are controlled and audits are quick.
- Full restatement history
- Data lineage to source
- Approval workflows
What changes when carbon accounting leaves the spreadsheet
One source of truth
Single source
A governed model replaces the fragile master spreadsheet.
Always audit-ready
Year-round
Your footprint is defensible at any point in the year, not just at report time.
Less manual effort
Hours saved weekly
Automated ingestion frees your team from re-keying data.

Frequently asked questions
What is carbon accounting?
- The process of measuring the greenhouse gas emissions an organisation causes, directly (Scope 1), through purchased energy (Scope 2) and across its value chain (Scope 3), by applying emission factors to activity data such as fuel, electricity and spend. Done properly it produces a footprint that an auditor can retrace to source documents.
Which emission factors apply in Australia?
- Scope 1 and 2 use the methods and factors in the NGER Measurement Determination. Scope 3 uses the National Greenhouse Accounts (NGA) Factors published each year by DCCEEW, supplemented by GHG Protocol guidance and supplier-specific data where available. Sustainability Manager carries the NGA factor library so the right vintage is applied automatically.
Can we start in Excel and move to Sustainability Manager later?
- Yes, and for a first baseline we often recommend it. Our carbon accounting playbook shows how to structure the workbook so the move is clean. The spreadsheet stops being good enough when the figures need assurance or when more than one person has to maintain them.
How is carbon accounting different from NGER reporting?
- NGER is a compliance report of facility-level Scope 1 and 2 to the Clean Energy Regulator for entities over the thresholds. Carbon accounting is the organisation-wide inventory across all three scopes that feeds AASB S2, targets and decarbonisation decisions. The same activity data serves both, so we build one model that produces both outputs.
What does assurance require of our carbon accounting?
- Under AASB S2, Scope 1 and 2 need limited assurance from the first reporting year. The assurer will test the boundary, the factor vintages, the calculation and the evidence behind a sample of figures. A governed data model with lineage and change history turns that from weeks of questions into a short review.
