Carbon dioxide equivalent (CO2-e) emissions – electricity
Theamountofgreenhousegasemissionsmeasuredincarbondioxide
equivalent (CO2-e) generated from electricity consumption (as defined
above)bythetotalineachAustralianState,TerritoryorGridDescription
from1Julyto30June.UndertheAustralianGovernment’sDepartmentof

incorporatedintothecalculationincludecarbondioxide(CO2), methane
(CH4)andnitrousoxide(N2O).QantasappliestheNGAFactorsconversions
and methodology for the calculation of CO2-e.
Carbon dioxide equivalent (CO2-e) emissions – natural gas
Theamountofgreenhousegasemissionsmeasuredincarbondioxide
equivalent (CO2-e) generated from Natural Gas consumption (as defined
above)from1Julyto30June.UndertheAustralianGovernment’s
Department of Climate Change National Greenhouse Accounts (NGA)
Factors,emissionsincorporatedintothecalculationincludecarbondioxide
(CO2), methane (CH4)andnitrousoxide(N2O). Qantas applies the NGA
FactorsconversionsandmethodologyforthecalculationofCO2-e.
Nitrogen oxide (NOx) – aviation
Theamountofnitrogenoxide(NOx)producedduringfuelcombustionof
Qantasontake-offandlandingtoaheightof3,000feetfrom1Julyto30
June.NOxemissionsfactorsarebasedontheenginetypeoftheaircraftand
determinedbyreferencetotheICAOEngineExhaustEmissionsDataBank.
Carbon dioxide (CO2) emissions per 100 revenue tonne
kilometres (RTKs)
Ameasureofcarbondioxide(CO2)emissionsefciencybasedonCO2
production per 100 RTKs for Qantas from 1 July to 30 June. CO2 emissions
foraviationaredenedabove.RTKsareastandardindustrymetricusedto
quantifytheamountofrevenuegeneratingpayloadcarried,takinginto
account the distance flown. RTKs comprise the passengers, freight and
mailcarriedmultipliedbytheGreatCircleDistance(GCD),whichisa
standardpublisheddistancebetweentwoairports.
Carbon dioxide equivalent (CO2-e) per 100 revenue tonne
kilometres (RTKs)
AmeasureofcarbondioxideequivalentCO2-eemissionsefciencybased
on CO2-e production per 100 RTKs for Qantas from 1 July to 30 June.
CO2-e emissionsforaviationasdenedabove.
Fuel per 100 revenue tonne kilometres (RTKs)
Ameasureofefciencybasedonfuelconsumptionper100RTKsfor
Qantas from 1 July to 30 June.
Nitrogen oxide (NOx) per landing take-off (LTO) cycle
Nitrogenoxide(NOx)emissionsproducedforQantasisperlandingand
take-off(LTO)cyclefrom1Julyto30Juneandismeasuredinkilograms
per LTO cycle.
Fuel jettison
The release of fuel at altitude to reduce the weight of the aircraft usually to
themaximumlandingweightfrom1Julyto30June.Theonlyaircraftin
theQantasGroup’seetwhichhaveaircraftfueljettisonsystemsare
QantasB747s,B767sandA380s.Typicalsituationswherefuelmaybe
releasedincludeconditionsinwhichanexpeditiouslandingwouldreduce
theexposuretopotentialadditionalproblemsthatcouldcompromise
safety or in the case of serious illness of crew or passengers who require
immediate medical attention.
Fuel spills reported
TheaccidentaldischargeofaviationfuelreportedbyQantasGroup
employees or equipment at airport sites from 1 July to 30 June and is
categorised as follows:
•Category1:spillvolumegreaterthan1,000litres;
•Category2:spillvolumegreaterthan100litresbutlessthan1,000litres;
and
•Category3:spillvolumelessthan100litres.
TheQantasGroupaimstominimisefuturespillsbyidentifyingthe
events resulting in aviation fuel spill occurrences and to put in place
corrective actions.
Economic contribution
Tourism spending by Qantas Group passengers
ThismeasurecomprisestheQantasGroup’scontributiontonationalexport
revenueanddomestictravellerexpenditure.
Nationalexportrevenueiscalculatedbythenumberofinboundvisitors
broughttoAustraliabyQantasandJetstarforthe12monthsto31May2009
(latestavailabledata)multipliedbytheassumedvisitorexpenditure(basedon
theaverageexpenditurepervisitoraccordingtoTourismAustralia’sMarch
2009InternationalVisitorSurvey(latestavailabledata)).Thisamountdoesnot
include the value of airfare and freight charges that accrue to Qantas from
overseassourceswhichalsorepresentexportrevenue.
DomestictravellerexpenditureiscalculatedasthenumberofQantasGroup
domesticpassengersforthe12monthsto31May2009(latestavailable
data)multipliedbytheaverageexpenditureperovernightvisitoraccording
toTourismAustralia’sMarch2009NationalVisitorSurvey(latestavailable
data). This amount includes the value of related airfares.
Asitisnotpossibletodisaggregatethedata,thecalculationshouldbe
viewed as indicative only e.g. the figure may include some international
visitorexpenditure(wheredomesticightsarepurchasedafterarrivalin
Australia)orunderstatetheexpenditureassociatedwithdomesticights
whichare‘roundtrip’.
Indirect economic contribution
ThismeasurecomprisesQantasGrouprevenuemultipliedbyaQantas
Groupeconomicmultiplierof2.1(ascalculatedbyAccessEconomics).
The multiplier is derived from Australian Bureau of Statistics input-output
tablesoftheAustralianeconomy.AccessEconomicsisaneconomicadvisory
companywhichprovidesexpertiseinanalysis,modellingandforecasting.
AccessEconomicswascommissionedbyQantastogainabetter
understandingoftheGroup’scontributiontotheAustralianeconomy.
A multiplier of 2.1 suggests that a $1 million increase in demand for
Qantas’servicesleadstoa$2.1millionincreaseinoutputfromallsectors
in the economy, including air transportation. In other words, the flow-on
effects to other sectors is $1.1 million.
