I-Airlines For America, i-A4A, isanda kukhipha amanye amaslayidi, iphindaphinda iqiniso lokuthi imboni yezindiza yayihlukile njengemboni emhlabeni wonke futhi yahlangana kudala ekuvumeni okuthile okubizwa nge-CORSIA, i-Carbon Offsetting and Reduction Scheme for International Aviation, I-CORSIA, ekhuluma ngokukhula kokungathathi hlangothi kwekhabhoni kwezokundiza, kusukela ngo-2021. Futhi inhloso lapho wukunciphisa ukukhishwa kwe-CO2 ngo-50% ngo-2050, uma kuqhathaniswa namazinga ka-2005.
Kusho ukuthini lokho? Nokho, ngo-2005, izindiza zathwala abagibeli abayizigidi eziyizinkulungwane ezingu-2.1. Ngo-2019, izinombolo zabagibeli zase zingaphezu kokuphindwe kabili zafinyelela ezigidini eziyizinkulungwane ezingama-4.6 futhi ukukhula kwehle kakhulu, ngokushesha okukhulu ngo-2020, vele, kangangokuthi namuhla sesibuyele emazingeni ka-2005 ngokwezibalo zabagibeli. Ukuncishiswa okumangazayo ngokusobala, futhi ngeke kuhlale lapho, ngethemba. Kodwa okubaluleke ngokufanayo, izinga lokukhishwa kwegesi liphansi kakhulu, liphansi kakhulu namuhla, cishe ama-30%, ngenxa yokusebenza kahle okukhulu kwezinjini zezindiza, futhi kwezinye izimo, izinqubo zokusebenza. Ngakho-ke, sifika ndawana thize, kodwa uma lokho kukhula kuqala ukubuyela emuva, kungenzeka noma yini.
Okuhle ukuthi ukungcola kwezindiza kuzoba ngaphansi kakhulu kwamazinga ka-2019, kuseneminyaka ethile ezayo. I-long-haul international, isibonelo, izophuza kakhulu ukubuya. Izilinganiso ziwukuthi cishe, kulo nyaka ngezinga eliphezulu, u-50% wohambo olude, okuwukusebenza komzimba obanzi, uzobuya. Futhi leyo misebenzi ngo-2019, ukusebenza komzimba okude isikhathi eside, kubalele cishe ama-40% wengqikithi ekhishwayo. Ngokukhipha ingxenye yalokho ku-equation, sibheka lapho nje kuphela, ukwehla okungama-20% kokukhishwayo, inani elibaluleke kakhulu.
Ngokunengqondo, lokho esikhuluma ngakho-ke, ngenxa yamanani ancishisiwe ohambo kanye nokundiza, ngakolunye uhlangothi, ingcindezi yokunciphisa ukukhishwa kwegesi esikhathini esifushane izokhululeka. Noma kungenjalo, futhi lokhu kungenzeka, ingcindezi izokhula ukuze kugcinwe ukukhishwa kwekhabhoni ezingeni elifanayo nalokhu okuyikho manje, okusho ukusetha kabusha isisekelo sokukhula. Ngicabanga ukuthi umphumela cishe ungaba kancane kukho kokubili, kodwa ngokushuba okukhulu ezingeni lesibili.
UBill Gates usanda kushicilela incwadi ethi How to Avoid a Climate Disaster. Futhi washo izinto eziningi ezinengqondo. Akusho ukuthi, kule ngxabano, umqondo omuhle ukuba noBill Gates ohlangothini lwakho, ngoba uthola ukuphindisela emuva kwabaningi, kodwa wenza amaphuzu amaningana afanelekile kumongo wezindiza, ngicabanga. Okokuqala, ayikho imali eyanele, isikhathi, noma intando yezombangazwe yokulungisa kabusha umkhakha wamandla eminyakeni eyi-10. Ngakho-ke, ukuzama ukufinyelela imigomo engenakwenzeka, vele ugwebe umhlaba ekuzuzeni okunganele kwesikhashana. Futhi, ukukhishwa kwekhabhoni, futhi lokhu kubalulekile ngokombono wethu wezokuthutha, ukukhishwa kwekhabhoni ngeke kufinyelele kuqanda nje ngabantu abandizayo noma abashayela kancane. Okudingekayo ngempela, ukushintsha izinto ngokuphawulekayo, kuyindlela ephelele. Kusho izindlela ze-carbon zero zokukhiqiza ugesi, ukwenza izinto, ukulima ukudla, ukugcina izakhiwo zethu zipholile noma zifudumele, nokuthutha abantu nempahla emhlabeni wonke.
Okubaluleke kakhulu, abantu badinga ukushintsha kakhulu indlela abakhiqiza ngayo. Futhi izigebengu ezimbi kakhulu zesimo sezulu, nezinto ezidinga ukushintsha kakhulu, insimbi, inyama, nosimende. Ukwenza insimbi nosimende kukodwa kwenza cishe u-10% wayo yonke igesi ekhishwa emhlabeni wonke, kanti inyama yenkomo iyodwa yenza ama-4%. Akazange asho, kodwa kungenzeka ukuthi, leyo mfashini nayo ibalwa endaweni ethile cishe ngo-10%. Lezi zonke izindawo ezingashintsha kakhulu ezingeni lomuntu siqu, singenza izinto zehluke. Kepha uthi, ngokusho kukaBill Gates, kugxilwe kakhulu ezinguqukweni ezidingekayo kwezokuthutha, izakhiwo, izimboni, amasiko nezepolitiki. Uthi akukho mpumelelo eyodwa engaxazulula zonke lezo zinto.
Kusukela endaweni yezindiza ikakhulukazi, iMicrosoft yenze isibonelo nge-Alaska Airlines, isibonelo. UBill Gates uthi, akuxazululeki ngokutshala izihlahla, osekuyinto engaziwa futhi mhlawumbe elahlekelwa isithunzi sayo kodwa ixazulule ngokuthenga uphethiloli wendiza osimeme. Njengoba esho, esinye isibonelo sokusebenzisa ukuthenga ukuze kuncishiswe amaphrimiyamu aluhlaza sibandakanya imboni yezindiza. Inkampani yakho, futhi ukhuluma ngezinkampani ezifana neMicrosoft, ingakwazi ukwehlisa umoya ophuma ekuhambeni kwabasebenzi ngokuthenga uphethiloli wendiza osimeme ngamamayela ayindizayo. Lokho kudala isidingo samafutha ahlanzekile, kuheha ukuqanjwa okwengeziwe kuleyo ndawo, futhi kwenza ukukhishwa kwekhabhoni okuhlobene nohambo kube isici ezinqumweni zebhizinisi lenkampani yakho. Ngakho-ke, iMicrosoft ne-Alaska Airlines basayine isivumelwano esifana nalesi seminye yemizila abayindizayo ibuya ngo-2020, futhi lokho kungenxa yokuthi iMicrosoft isebenzisa i-Alaska Airlines kabanzi.
