The Net Zero Australia (NZAu) project models pathways to net zero and other futures to illustrate:

• the scale, complexity and cost of decarbonising Australia's' energy system compared to not doing so
• the potential implications of key choices
• the potential impacts across society, the economy and the environment. 

The report updates previous modelling with the latest inputs and only focuses on domestic decarbonisation. It models four scenarios for the domestic system: a reference scenario, current policies, net zero 2050 and net zero extended.

The report provides a summary of modelling results and their implications for the following areas:

• energy production, storage and build
• energy use, emissions and targets
• maps – new build electricity, hydrogen, CO2 and water transmission connects major centres
• costs and investment.

The report is accompanied by datasheets and the document Methods, assumptions, scenarios and sensitivities.
