Global aviation emissions
2% Global GHG emissions
689 Million tonnes CO2-e
Australian aviation emissions
3% Australia’s GHG emissions
17 Million tonnes CO2-e
Emission + RFI Estimates
RFI = 2.7 ±1.5
Worst Case
RFI = 4.2

Airport GHG Emissions
Scope 2: terminal electricity use
Scope 1: on-site generator fuel
Scope 1: net change to carbon storage
fate of cleared vegetation* Scope 3: aircraft movements (airlines)
radiative forcing index (RFI)*
Scope 1: airport fleet vehicles
Scope 2: airport lighting*
Scope 3: leaseholder electricity use
Scope 1: fuel used in construction
Scope 3: embodied emissions in materials*
Emissions are divided into scopes based
on the responsibilities of the
owners/operators of the airport. The
overall impact of the expansion on
greenhouse gas emissions conceptually
includes all scopes, but not all can be
effectively quantified.
Scope 1 – direct emissions
Scope 2 – purchased electricity
Scope 3 – upstream/downstream
emissions as selected.
* data not available or source excluded
Scope 1: waste-related emissions
(because waste emissions are council
responsibility and council owns airport) Scope 3: Passenger pick-up, drop-off*
Freight transfer*
Scope 3: workforce commuting*
Scope 3: general aviation
Scope 3: baggage handling fuel*
Task
Annual inventory of emissions
Aircraft emissions including landing and take-off emissions
