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.

Quick estimate only. Source: DCCEEW NGA Factors 2026. 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 provides this, with timing agreed after reviewing scope and records. Tender-Ready Carbon Snapshot™ supports urgent tenders, with scope and timing agreed after reviewing the request and records.

    Tender-readiness actions

    This is a Scope 1 + 2 ballpark using NGA 2026 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 a documented inventory with timing agreed after a review of scope and records, see Carbon Footprint Analysis. For a focused tender response with timing agreed after reviewing the request and records, see Tender-Ready Carbon Snapshot™.
