Isifinyezo sokuqonda

Imboni yezasolwandle iqhuba indlela ebheke ekusaseni eliluhlaza, njengoba sekuvela imikhumbi yezimpahla esebenza ngogesi kanye nezinhlelo zokunqanda ukukhishwa kwekhabhoni. Kusukela ezikebheni zeziqukathi ezisebenza ngebhethri kuya eziteshini zokudokha ezisebenza ngogesi, lokhu kuthuthukiswa kunganciphisa kakhulu izinga lekhabhoni lemboni. Kodwa-ke, uguquko luphinde lusho imithelela eminingana, okuhlanganisa ukujwayela kwezobuchwepheshe embonini yonke, izindleko ezingase zibe phezulu, kanye nezinguquko zokusebenza zesikhathi eside.

Umongo wokuhambisa ikhabhoni ephansi

Imboni yasolwandle, ebhekele ingxenye enkulu yokukhishwa kwekhabhoni emhlabeni wonke, iqala uhambo olubheke ekusaseni eliluhlaza. Ngokwesiko uthathwa njengomkhakha oyinselele wokuguqula, ukuthunyelwa kwemikhumbi cishe kumaphesenti amabili okukhishwa kwekhabhoni emhlabeni wonke—isibalo esingase sikhuphuke siye kumaphesenti ayi-15 ngaphandle kwezinyathelo ezifanele. Nokho, ababambiqhaza bemboni, ngaphansi kohlaka lweNhlangano Yezolwandle Yamazwe Ngamazwe (i-IMO), benze isibopho sokunciphisa ukukhishwa kwekhabhoni dioxide emikhunjini ngamaphesenti angama-50 ngo-2050.

Lo mgomo wokuvelela ugqugquzele igagasi lokuqamba okusha kuyo yonke imboni. Imikhumbi iyahlelwa kabusha futhi ihlelwa kabusha ukuze kwehliswe ukuthembela kumafutha asuselwa ku-petroleum. Iziteshi zokushaja zemikhumbi kagesi ziyathuthukiswa, kanye namabhethri esiqukathi esisebhodini, izinto zokubasa eziphuma kugesi yemvelo ewuketshezi, kanye nemikhumbi eyingxubevange. Le mizamo ilungisa kabusha isimo sasolwandle, iphushela imboni ikusasa elisimeme.

Enkambweni yokuqala, umakhi wemikhumbi waseDashi u-Port Liner usewafakile kakade ama-container kagesi ukuze athunyelwe phakathi nezwe. Lezi zikebhe, ezinikezwa amandla umhlinzeki wamandla angenayo i-carbon i-Eneco, aklanyelwe ukusebenza ngaphandle kwezisebenzi noma igumbi lenjini, okuvumela indawo eyengeziwe yomthwalo. Khonamanjalo, ichweba laseMontreal seliqale iphrojekthi yokuphehla ugesi ogwini oluvumela imikhumbi yokuhamba ngomkhumbi ukuthi inikezwe amandla kagesi.

Umthelela ophazamisayo

Kusukela kwasayinwa iSivumelwano saseParis ngo-2016, izinqubomgomo zezemvelo emhlabeni wonke ziye zaqina kakhulu. Ukushintshela ekuthuthweni kwemikhumbi enekhabhoni ephansi kuyingxenye yalo mnyakazo obanzi, futhi umthelela wawo kwezemvelo kungenzeka ubaluleke kakhulu. Ukushintshela kwemboni yasolwandle kumandla aluhlaza, okungenzeka ngokusebenzisa indlela exubile ehlanganisa amabhethri nophethiloli, kuphawula iphuzu elibalulekile ohambweni lwayo lwezemvelo.

Ukushintshela ekuthuthweni kwemikhumbi okusimeme kungadala namathuba amasha embonini. Onjiniyela nabakhi bemikhumbi bangase babone ukwanda kwesidingo njengoba izinkampani zicinga ubuchwepheshe nezisombululo zokwenza izimoto zabo zivumelane nemvelo. Nakuba inguquko yokuqala ingase ize nezindleko eziphezulu, izinzuzo zesikhathi eside zingabandakanya izindleko ezincishisiwe zokusebenza.

Ngaphezu kwalokho, umthelela wokuthutha olwandle esimeme ungadlulela ngale kwemboni yasolwandle. Kungase kuholele ekwehleni kwempahla emgwaqeni, njengoba amaloli amaningi njengamanje esebenzisa udizili. Njengoba imboni yezasolwandle yenza igxathu ekusimameni, ingase ibangele umthelela omubi wokuqaphela imvelo kuwo wonke umkhakha wezokuthutha.

Imithelela yokuthunyelwa kwekhabhoni ephansi 

Imithelela ebanzi yokuthunyelwa kwekhabhoni ephansi ingabandakanya:

• Ama-cruise liners anciphisa izindleko futhi abambe iqhaza embonini yezokuvakasha neyokuvakasha esimeme.
• Ukunciphisa umthelela wemvelo wemikhumbi yokugada olwandle kanye nomkhumbi wasemsebenzini.
• Ukuthuthukiswa kwezixazululo ezintsha zobunjiniyela kanye nobuchwepheshe bokuthutha okuluhlaza.
• Ukwehla kwezimpahla zomgwaqo, okunomthelela ekwehliseni ukukhishwa kwekhabhoni emkhakheni wezokuthutha.
• Ushintsho ekuqeqesheni imboni kanye nemfundo ukuhlomisa abasebenzi ngamakhono adingekayo ekuguqukeni kokuluhlaza.
• Ukubuyekezwa kwezinhlaka zokulawula ukuze kuhlangatshezwane nokukhula kobuchwepheshe bekhabhoni ephansi.
• Ukutshalwa kwezimali okwengeziwe kwingqalasizinda yamandla avuselelekayo emachwebeni.
• Ukuqwashisa umphakathi ngomthelela wemvelo wemikhumbi kanye nemizamo yemboni ekusimameni.

Imibuzo okufanele icatshangelwe

• Ingabe okwanele okwenziwayo ukuqinisekisa ukuthi imboni yemikhumbi ifinyelela izinhloso zayo zokunciphisa ikhabhoni ngo-2050?
• Imiphi eminye imithombo yamandla avuselelekayo, uma ikhona, engasetshenziselwa ukunika amandla imikhumbi yemikhumbi?
