If you calculate emissions for an Australian organisation, this is the source you are standing on. The National Greenhouse Accounts (NGA) Factors — still labelled DISER in many data platforms, now published by DCCEEW — is the Australian Government’s annual workbook of emission factors, and it is the single source behind every value in our emission factors database.
What It Is
The NGA Factors workbook translates Australia’s national inventory methods into factors any organisation can apply: kilograms of CO₂-e per kilowatt hour of electricity, per litre of diesel, per tonne of waste to landfill. It is prepared by the Department of Climate Change, Energy, the Environment and Water in conjunction with the Australian National Greenhouse Accounts, drawing on the NGER (Measurement) Determination 2008.
The “DISER” label persists because the Department of Industry, Science, Energy and Resources published earlier editions until climate functions moved to DCCEEW in 2022. Same dataset, new masthead.
What It Covers
| Category | Examples | Scope |
|---|---|---|
| Electricity | State grid factors, residual mix, transmission losses | 2 & 3 |
| Solid fuels | Coals, coke, wood, bagasse | 1 & 3 |
| Gaseous fuels | Natural gas, LNG, biogas, hydrogen | 1 & 3 |
| Liquid & transport fuels | Diesel, petrol, LPG, jet fuel, biofuels | 1 & 3 |
| Waste | Landfill by waste type, incineration, composting, wastewater | 1 & 3 |
| Refrigerants | GWPs for common gases, leakage rates | 1 |
Factors are activity-based — you multiply real consumption quantities (kWh, litres, tonnes) by the factor — and expressed in CO₂-e using IPCC AR5 global warming potentials.
When to Use It
Use the NGA Factors for any Australian activity data: it is the expected source for NGER reporting, Climate Active certification and AASB S2 disclosures covering Australian operations. For spend-based estimation where no activity data exists, pair it with an input-output database such as EXIOBASE or CEDA.
NetNada applies the current NGA Factors automatically — every factor in our database carries its table reference and citation from this publication.
