Carbon Footprint Calculator
Get a ballpark Scope 1 and Scope 2 carbon footprint for your Australian business in 2 minutes. Uses NGA emission factors. Useful for early-stage planning, tender pre-checks, and budget conversations.
Direct emissions from fuel your business burns. Enter annual quantities. Leave blank if not applicable.
Grid electricity purchased. Pick your state for the correct emission factor.
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.
