National Greenhouse Accounts Factors 2018
The National Greenhouse Accounts (NGA) Factors are methods that help companies and individuals estimate greenhouse gas emissions.
About the NGA Factors
The NGA Factors is not published for the purposes of reporting under the National Greenhouse and Energy Reporting Act 2007. While drawing on the National Greenhouse and Energy Reporting (Measurement) Determination 2008, the methods described in the NGA Factors have a general application to the estimation of a broader range of greenhouse emissions inventories.
Unless otherwise stated, the methods for calculating emissions listed in this document are "Method 1" from the National Greenhouse and Energy Reporting (Measurement) Determination 2008 incorporating the National Greenhouse and Energy Reporting (Measurement) Amendment Determination 2018 (No. 1), and the Technical guidelines for the estimation of greenhouse gas emissions by facilities in Australia - 2017-18 reporting year (October 2017). The Technical Guidelines have been designed to support reporting under the NGER Act 2007.
The default emission factors listed have been estimated by our department using the Australian Greenhouse Emissions Information System (AGEIS) and are determined simultaneously with the production of Australia's National Greenhouse Accounts. This ensures that consistency is maintained between inventories at company or facility level and the emission estimates presented in the National Greenhouse Accounts. The emission factors are referred to in this document as National Greenhouse Accounts default emission factors.
More information on the estimation methods employed in the National Greenhouse Accounts is available in the National Inventory Report 2016. The methods used at the national level, and reflected in the factors reported here, are consistent with international guidelines and are subject to international expert review each year.
