I-International Air Transport Association's (IATA) okokuqala ngqa i-World Sustainability Symposium (WSS) ivulwe eMadrid namuhla kugxilwe ezenzweni ezidingekayo ukuze kufezwe ukuzibophezela kwemboni yezokundiza ekukhipheni i-zero CO2 ekukhishweni ngo-2050.

“Isidingo sokuhamba ngendiza sikhombisa ukuthi sonke sifuna umhlaba lapho singandiza khona futhi senze lokho ngenkathi sinciphisa indawo yethu ye-carbon. Ukuzinza kuyinselelo enkulu kakhulu yemboni, futhi asihlehli emisebenzini yethu. Ukuzibophezela kwethu ku ingqikithi enguziro CO2 ukukhishwa ngo-2050 kuqinile. I I-World Sustainability Symposium izovumela ababambiqhaza ukuthi bagxile emsebenzini ofanayo, ngokulangazelela nangokuphuthuma, ukwakha umfutho wokufinyelela umgomo wethu. Silapha ukuze sabelane ngokufundiwe, sihambisane nesivinini soshintsho, futhi silungise umsebenzi wethu ngokufanele, kuyilapho sihlanganisa ohulumeni nababambiqhaza ukuze kube lula ukukhishwa kwekhabhoni embonini,” kusho u-Willie Walsh, uMqondisi Jikelele we-IATA.

Izinto ezibalulekile ezisiza ukuzuza ukukhishwa kwe-CO2 ku-zero ngo-2050 okukhulunywa ngakho ku-WSS zifaka:

Amasu okunciphisa umthelela wesimo sezulu

I-Sustainable Aviation Fuels (SAF) kulindeleke ukuthi yenze umnikelo omkhulu kakhulu (62%) ekuzuzeni i-net zero ngo-2050. Isidingo se-SAF siphezulu, kodwa ukuhlinzekwa kuyancipha. Futhi, izinselelo ezibalulekile zisasele ekukhuphuleni amazinga adingekayo. Ochwepheshe bomhlaba wonke bazohlola izici ezisekelayo zesixazululo:

Izinqubomgomo zikahulumeni zokugqugquzela ukukhiqiza,
Ukuhlukahluka kwezindlela kanye nemfuyo ukukhiqiza i-SAF,
Izinhlaka zomhlaba wonke eziqinisekisa ukuthi ukuphuma kwe-SAF ekukhiqizweni kwamandla avuselelekayo kuyahambisana,
Ukuheha ukutshalwa kwezimali ukuze kukhuliswe ukukhiqizwa,
Ukusungula uhlaka lwezimali oluqinile lwe-SAF, olusekelwe kuchungechunge oluthenjwayo lokugcinwa kwezincwadi olusekela uhlelo lwezincwadi kanye nesimangalo lokulandelela,
Amathuba okukhiqizwa kwe-SAF ukuze ahlomule ekuthuthukiseni ubuchwepheshe bokubanjwa kanye nokugcinwa kwekhabhoni.

Abahlanganyeli be-WSS bazophinde babheke amasu okunciphisa abanzi ahlanganisa i-hydrogen noma indiza esebenza ngogesi kanye nokuthuthukiswa kokusebenza kahle okuqhubekayo kubuchwepheshe be-airframe kanye nenjini. Iqhaza lokusebenzisana emaketangeni entengo nawo lizobhekwa. Ngokuphawulekayo, indlela yemboni yezokundiza yokunciphisa imithelela yayo kwezemvelo ibanzi. Izihloko ezilandelayo ziphakathi kwemithelela engeyona eye-CO2 ezodingidwa kwa-WSS:

Izibuyekezo emizamweni yokuhlola, ukuqapha, ukubika futhi ekugcineni kuncishiswe imithelela yokuvimbela,
Ukuqeda ipulasitiki ekhabetheni lendiza.

2. Ukulandelela ukuqhubeka kufinyelele kuziro

Ngo-2021, izinkampani zezindiza ezingamalungu e-IATA zagunyaza isinqumo sokuzuza ukukhishwa kwe-CO2 eyiziro ngo-2050. Ngo-2022, i-International Civil Aviation Organisation (ICAO) yamukela i-Long Term Aspirational Goal (LTAG) yokundiza kwamazwe ngamazwe kokukhipha i-CO2 eyiziro 2050. Nakuba lezi ukuzibophezela kusungule umgomo ophelele onosuku lokuphela olucacile, alukho uhlelo oluphathekayo oselusunguliwe lokuthi inqubekelaphambili izobhekwa kanjani futhi ilandelelwe kanjani ezingeni lemboni. I-Symposium izophinde ibheke indlela yokusebenza engaguquguquki kanye nendlela yokubika edingekayo ukuze kulandelelwe ngokukholakalayo nangokunembile inqubekelaphambili efinyelela ku-zero yonke ngomgomo ka-2050. Izocabangela izindlela ezehlukene zokuqeda ikhabhoni njenge-SAF, isizukulwane esilandelayo sezindiza nobuchwepheshe bokuthutha, ukuthuthukiswa kwengqalasizinda nokusebenza, kanye nokususwa kwekhabhoni/ukususwa kokukhishwa kwensalela.

Izinsiza ezisemqoka

Izinqubomgomo zamasu eziqondaniswe emhlabeni wonke zokuhlinzeka ngezinzuzo kanye nokwesekwa kwezindiza zibalulekile ekushintsheni kwemboni ku-net-zero. Njengazo zonke ezinye izinguquko zamandla eziyimpumelelo, ikakhulukazi uguquko lwamandla avuselelekayo, ukusebenzisana phakathi kohulumeni nababambiqhaza bemboni kubalulekile ekudaleni uhlaka oludingekayo ukuze kuzuzwe izinjongo zokuqeda ikhabhoni.

ISimpoziyam izongena ngokujulile ezindimeni ezibalulekile ezodlalwa ezezimali kanye nenqubomgomo ekusheshiseni inqubekelaphambili endleleni yokuthola iqanda, futhi ekugcineni, ukusiza ukwehlisa ezinye zezindleko nokutshalwa kwezimali okudingekayo kuyilapho kuvumela ukushintshwa kwamandla.

“Lo mcimbi uhlose ukuhlonza izindawo okungenziwa ngazo izinto ezibambekayo ezingasheshisa ukushintshela kwendiza ekukhiqizweni kwe-CO2 ku-net-zero ngo-2050, njengoba kusobala ukuthi asikho isikhathi sokumosha. Lena inselele enzima futhi enamandla, futhi asikho isenzo esisodwa esizonikeza isisombululo somlingo ngokwaso. Kunalokho, sidinga ukuqhubekela phambili kuyo yonke imikhakha kanye kanye, futhi lokhu kuzodinga izinga eliyingqayizivele lokubambisana kuzo zonke izingxenye zemboni yethu, kanye nabalawuli kanye nomkhakha wezezimali. Yingakho i-WSS kanye nezinhlelo zayo zesikhathi esizayo zibaluleke kakhulu - ukuvumela abenzi bezinqumo ababalulekile, konke okudingekayo ekushintsheni kwezindiza, ukuthi babhekane nemibono kanye nezisombululo zenkulumompikiswano ukuze senze izinto zenzeke, sindawonye”, kusho uMarie Owens Thomsen.
