SAF: Aviation's Key to Decarbonization
Daim ntawv tshaj tawm "Sustainable Aviation Roj nyob rau hauv Tuam Tshoj - Txoj Kev rau Carbon Neutrality rau Kev Lag Luam Kev Lag Luam," muab tso ua ke los ntawm Deloitte Tuam Tshoj, tau raug tso tawm (tom qab no hu ua "Daim Ntawv Qhia"). Daim ntawv tshaj tawm piav qhia txog qhov tseem ceeb ntawm kev ua tiav net-zero emissions rau txoj kev loj hlob ntawm kev lag luam aviation, qhia txog txoj hauv kev rau carbon neutrality rau kev lag luam aviation hauv Suav teb thiab thoob ntiaj teb, thiab txhais qhov ua tau thiab ua tau zoo ntawm Sustainable Aviation Fuel (SAF) hauv kev txo qis aviation emissions los ntawm ntau qhov perspective.
Kev lag luam aviation pab nyiaj $ 3.5 trillion rau GDP thoob ntiaj teb (4.1%) thiab suav txog 3% ntawm cov pa roj carbon dioxide emissions thoob ntiaj teb. Txawm li cas los xij, raws li lwm cov kev lag luam decarbonize, qhov feem ntawm carbon dioxide emissions los ntawm kev lag luam aviation tuaj yeem ncav cuag 22% los ntawm 2050. Lub International Air Transport Association (IATA) kwv yees tias Asia - cheeb tsam Pacific yuav dhau los ua thaj tsam loj tshaj - loj hlob rau cov neeg caij tsheb. Nyob rau hauv 2021, Tuam Tshoj lub domestic aviation neeg nrog caij ua lag luam accounted rau 18.9% ntawm lub ntiaj teb no kev ua lag luam.
Xie An, Tus Thawj Coj ntawm Deloitte Tuam Tshoj Lub Tsev Haujlwm Saib Xyuas Kev Nyab Xeeb thiab Kev Nyab Xeeb Kev Nyab Xeeb, tau hais tias kev lag luam aviation tau lees paub tias yog "nyuaj-rau- abate" sector, thiab Sustainable Aviation Fuel (SAF) yog cov cuab yeej ua lag luam uas tuaj yeem txo qis kev siv huab cua mus ncig hauv lub sijhawm ze. Txhua tus neeg koom nrog SAF, suav nrog cov khoom siv raw thiab cov khoom siv roj, cov dav hlau, cov tuam txhab dav hlau, cov chaw muab kev pabcuam, cov tub ua lag luam, thiab cov koomhaum tswj hwm, zoo siab txog kev decarbonization, tab sis yuav tsum tau ua ntxiv. Sustainable Aviation Fuel (SAF) yog ib qho poob - hauv cov roj ua kua uas tuaj yeem txo cov pa roj carbon emissions txog li 85% piv rau cov roj aviation ib txwm siv, nyob ntawm cov khoom siv raw thiab cov txheej txheem tsim khoom siv.
Muaj ntau txoj hauv kev los ua kom tiav decarbonization hauv kev lag luam aviation, suav nrog kev txhim kho roj efficiency, siv Sustainable Aviation Fuel (SAF), carbon offsetting, txais yuav cov tshuab hluav taws xob tshiab xws li roj teeb thiab hybrid xyaw, thiab siv hydrogen. Ntawm cov no, kev siv SAF yog thawj txoj kev decarbonization rau 30 xyoo tom ntej, vim nws tuaj yeem siv ncaj qha rau cov dav hlau uas twb muaj lawm. Tam sim no, SAF yog tsim los ntawm cov peev txheej xws li cov khoom pov tseg hauv hav zoov, cov khib nyiab ua liaj ua teb, siv roj ua noj, thiab cov khib nyiab hauv nroog. Qhov "sustainability" ntawm SAF yog tus yam ntxwv ntawm cov khoom siv raw uas tsis cuam tshuam rau cov qoob loo zaub mov lossis dej, tsis txhob ua rau cov ntoo deforestation los yog av degradation, thiab rov ua dua cov pa roj carbon monoxide khaws cia hauv biomass raw khoom.
Raws li Deloitte qhov kev kwv yees, Tuam Tshoj txoj kev lag luam aviation yuav tsum ua cov kauj ruam tseem ceeb los ua kom tiav International Air Transport Association's (IATA) kev cog lus kom ua tiav net- xoom emissions los ntawm 2050, tsav SAF ntau lawm thiab thov mus rau theem tsim nyog.
Nws tau kwv yees tias los ntawm 2030, Tuam Tshoj tag nrho aviation roj noj yuav ncav cuag 60.5 lab tons, thiab los ntawm 2050, daim duab no yuav tsum ncav cuag 132.5 lab tons.
Yog tias Tuam Tshoj txoj kev lag luam aviation ua raws li IATA lub hom phiaj kev siv SAF (5.2%), Tuam Tshoj qhov kev thov SAF yuav tsum ncav cuag 3 lab tons hauv ib xyoos los ntawm 2030. Nrog rau kev nce qib ntawm kev siv tshuab thiab kev nce qib ntawm Tuam Tshoj cov hom phiaj decarbonization, Tuam Tshoj qhov kev thov SAF tau kwv yees kom ncav cuag 86 lab 5 tons ib xyoos twg.
Txhawm rau tsav txoj kev loj hlob zoo li no, kev lag luam yuav tsum tau ntsuas los txo cov nqi tsim khoom thiab sib sau ua ke ob qho tib si hauv tsev thiab thoob ntiaj teb kev thov rau SAF.
Robert Hansor, Tus Thawj Coj ntawm Risk Advisory ntawm Deloitte Tuam Tshoj, hais ntxiv tias kev lag luam aviation muaj kev sib raug zoo nrog cov lag luam thiab cov tib neeg. Aviation emissions account rau ib qho tseem ceeb ntawm cov tuam txhab Scope 3 cov pa roj carbon monoxide emissions, ua rau lawv muaj kev sib tw rau cov tuam txhab carbon txo. Tsuas txo cov kev mus ncig ua lag luam tsuas yog tsis yooj yim daws qhov teeb meem. Yog li ntawd, SAF ua lub luag haujlwm tseem ceeb hauv kev decarbonization ntawm kev lag luam aviation. Tuam Tshoj muaj ntau cov khoom siv ntawm SAF raw cov ntaub ntawv thiab muaj peev xwm zoo rau kev tsim kho kom ruaj khov ntawm SAF. Txawm li cas los xij, kev hloov pauv ntawm kev lag luam aviation tseem xav tau kev sib koom tes thoob plaws tag nrho cov txiaj ntsig, kev txhawb nqa txoj cai, thiab kev nqis peev ntau ntawm peev thiab sijhawm.
