Quick estimate only. Source: DCCEEW NGA Factors 2025. This calculator gives an indicative Scope 1 + 2 result using the latest NGA emission factors. For tender responses, AASB S2 reporting, or supplier questionnaires, you need a documented, audit-ready inventory. Carbon Footprint Analysis delivers that in 2 to 4 weeks. Tender-Ready Carbon Snapshot™ delivers in 3 to 5 business days for urgent tenders.

What this calculator does not cover

This is a Scope 1 + 2 ballpark using NGA 2025 factors. For tender responses, AASB S2 reporting or supplier questionnaires, you need a GHG Protocol aligned inventory that also covers:

  • Scope 3 (purchased goods, freight, business travel) — often 70%+ of an SME's footprint. Check which categories matter for your industry with the Scope 3 Materiality Check.
  • Refrigerants and fugitive emissions (cool rooms, HVAC, vehicle A/C). Look up GWPs in the NGA Factors lookup.
  • Documented methodology, base year, organisational boundary (control vs equity share) — required for assurance.
  • Year-on-year tracking with audit trail to source activity data.

For an audit-ready inventory in 2–4 weeks, see Carbon Footprint Analysis. For an urgent tender response in 3–5 business days, see Tender-Ready Carbon Snapshot™.

Want this audit-ready?

A quick estimate is a great starting point. For tender responses, AASB S2 compliance, or supplier questionnaires, your numbers need a documented methodology, source data trail, and verified factors. That is what Aethiro delivers.
