Estimates of Australian health system greenhouse gas emissions 2021–22

The estimate includes emissions from: 

• Scope 1: Direct emissions, including natural gas and liquid fuels from sources such as stationary fuel use, anaesthetic gases, or fuel use in vehicles owned or leased by the health system
• Scope 2: Indirect energy-related emissions from purchased energy used by the health system
• Scope 3: Other indirect emissions, primarily from goods and services purchased by the health system
• patient travel to and from health facilities.

Estimates will be updated regularly to ensure Australia is on track for net zero health system emissions by 2050.
