The National Greenhouse Accounts (NGA) Factors provide methods that help companies and individuals estimate greenhouse gas emissions.
The NGA Factors must not be used to meet reporting requirements under the National Greenhouse and Energy Reporting (NGER) Act 2007. Further information on reporting under NGER can be found on the Clean Energy Regulator’s website.
While drawing on the National Greenhouse and Energy Reporting (Measurement) Determination 2008, companies can apply the factors and methods to a broader range of emissions estimates.
The NGA Factors are updated and published each year.
