2. Global aviation emissions
2% Global GHG emissions
689 Million tonnes CO2-e

3. Australian aviation emissions
3% Australia’s GHG emissions
17 Million tonnes CO2-e

4. Emission + RFI
Estimates
RFI = 2.7 ±1.5
Worst Case
RFI = 4.2
Aviation in Australia
12% Australia’s GHG

5. Airport GHG Emissions
Scope 3:
Scope 3:
Scope 1:
aircraft movements (airlines)
radiative forcing index (RFI)*
net change to carbon storage
fate of cleared vegetation*
general aviation
Scope 2:
Scope 1:
terminal electricity use
on-site generator fuel
Scope 1: fuel used in construction
Scope 3: embodied emissions in materials*
Scope 2: airport lighting*
Scope 3: leaseholder electricity use
Scope 3: workforce commuting*
Scope 3: baggage handling fuel*
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 1: airport fleet vehicles
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
