NGA Emission Factors Lookup

Look up Australian National Greenhouse Accounts (NGA) emission factors for Scope 1 fuels, Scope 2 electricity by state, and common refrigerants. Plus a quick built-in calculator.

Source: DCCEEW NGA Factors 2025 (AR5 GWPs). Factors are rounded for quick reference and reflect the August 2025 NGA workbook (Tables 1, 5, 6, 8, 9, 11). For compliance, audit, or AASB S2 reporting, always verify against the latest official DCCEEW NGA Factors workbook. NGA Factors are updated annually; electricity factors in particular shift each year as the renewable energy mix evolves.
