ukuphathwa kobungozi besimo sezulu

Njengoba iningi lomhlaba liqinisa imizamo yokulwa nokuguquguquka kwesimo sezulu, indima yezimali zesimo sezulu isibaluleke kakhulu. Isivumelwano saseParis sizibekele umgomo obalulekile: ukugcina izinga lokushisa lomhlaba likhuphuka lingaphansi kuka-2°C, ngokuzibophezela okuqinile ekulikhawuleleni libe ngu-1.5°C. Ukufeza lokhu okuhlosiwe kudinga uguquko olubalulekile emnothweni womhlaba, ukususa ukutshalwa kwezimali ezimbonini ezikhipha umoya ongcolile futhi kuyiswe ezixazululweni ezinemvelo, njengamandla avuselelekayo, ezokuthutha ezisimeme, nengqalasizinda eluhlaza. Kodwa-ke, ukuqinisekisa ukuthi ukuhamba kwezimali kuhambisana ngokweqiniso nezinjongo zesimo sezulu kudinga uhlaka olusobala, olujwayelekile lokulandela umkhondo kanye nokubika ukutshalwa kwezimali kokunciphisa isimo sezulu. Izimiso Ezivamile Zokulandelela Izimali Zesimo Sezulu, ezithuthukiswe amabhange okuthuthukisa amazwe amaningi (MDBs) kanye ne-International Development Finance Club (IDFC), zifeza le njongo ngokusungula indlela ecacile yokufaneleka yokutshalwa kwezimali okuhambisana nesimo sezulu kuyilapho ingafaki leyo ebukela phansi imizamo yesikhathi eside yokususa ikhabhoni. Lesi sihloko sihlola izimiso ezibalulekile zokulandela umkhondo wezezimali zokuncishiswa kwesimo sezulu, imikhakha ezuzayo ekutshalweni kwezimali okuluhlaza, kanye nekusasa lamasu ezezimali okuhloswe ngawo ukusheshisa ukusebenza kwesimo sezulu. Iqhaza Lezezimali Zokunciphisa Isimo Sezulu Izimali Zokunciphisa Isimo Sezulu iyithuluzi elibalulekile lokweseka ukuguqukela emnothweni ongenaziro. Iqinisekisa ukuthi imali eyinhloko iqondiswe ekutshalweni kwezimali: 1. Nciphisa noma Ugweme Ukukhishwa Kwegesi Ebamba Ukushisa (GHG) Ukunciphisa ukukhishwa kwesisi esibamba ukushisa (GHG) kuyinsika ewumgogodla wezezimali zokuncishiswa kwesimo sezulu, njengoba kubhekwana ngqo nomsuka wokufudumala kwembulunga yonke. Ngokushintsha ukutshalwa kwezimali kumandla ahlanzekile, ezokuthutha ezingcolisa umoya omncane, nengqalasizinda eyonga ugesi, singanciphisa kakhulu ukukhishwa kwekhabhoni sibe sithuthukisa ukukhula komnotho kanye nokusungula izinto ezintsha. Amasu abalulekile ahlanganisa ukusuka kumafutha ezinsalela ezimbiwa phansi kuye emithonjeni yamandla avuselelekayo, ukufaka ugesi izinhlelo zokuthutha, kanye nokuthuthukisa ukonga kwamandla ezakhiweni nasezimbonini. Lezi zinyathelo azinciphisi kuphela ukuncika emandleni anekhabhoni ephezulu kodwa futhi zakha isisekelo sekusasa elisimeme, elingenaziro. 2. Thuthukisa Ukuchithwa Kwekhabhoni Nakuba ukwehlisa ukukhishwa kwekhabhoni kubalulekile, kubalulekile ngokufanayo ukususa ikhabhoni ekhona kakade (CO₂) emkhathini ukuze kuncishiswe ukuguquka kwesimo sezulu ngempumelelo. Ukuthunjwa kwekhabhoni kudlala indima ebalulekile kulo mzamo ngokubamba nokugcina i-CO₂ ngokusebenzisa izixazululo zemvelo nezobuchwepheshe. Ukutshalwa kwezimali ekutshalweni kabusha kwamahlathi kanye nokugawulwa kwamahlathi kubuyisela amahlathi asebenza njengamasinki e-carbon emvelo, kuyilapho ukulima okuvuselelayo kuthuthukisa impilo yenhlabathi, okwandisa amandla awo okugcina i-carbon. Ukwengeza, ubuchwepheshe be-carbon capture and storage (CCS) buhlinzeka ngesixazululo sezinga lezimboni ngokucupha i-CO₂ ezitshalweni zamandla nezimboni ngaphambi kokuba ingene emkhathini. Lezi zindlela zisebenza ndawonye ukuze kuncishiswe ukungcola kanye neqhaza emnothweni ohambisana nesimo sezulu. 3. I-Transition High-Emission Industries Izimboni ezinzima njengensimbi, usimende, namakhemikhali ziphakathi kwezinto ezinegalelo elikhulu ekukhiqizweni kwekhabhoni emhlabeni wonke. Ukukhipha ikhabhoni kule mikhakha kubalulekile ukuze kuzuzwe umnotho ongenaziro, kodwa ukwenza kanjalo kudinga ukutshalwa kwezimali okuhlosiwe kubuchwepheshe obusha, obunekhabhoni ephansi. Esinye sezixazululo ezithembisayo kakhulu i-hydrogen eluhlaza, esebenza njengenye indlela ehlanzekile kumafutha ezinto ezimbiwa phansi ezinqubweni zezimboni. Ukwengeza, izinhlelo zomnotho eziyindilinga—njengokuncishiswa kwemfucuza, ukugaywa kabusha, nokuphinda zisetshenziswe—zisiza ukunciphisa ukukhishwa kwekhabhoni ngokunciphisa ukusetshenziswa kwensiza. Ukwamukelwa kwezinto zokwakha ezisimeme, ezifana nosimende ongenayo i-carbon-negative nensimbi egaywe kabusha, kunciphisa kakhulu umthelela wemvelo womkhakha wokwakha. Ngaphandle kohlelo oluqinile lokulandelela ukutshalwa kwezimali okuhambisana nesimo sezulu, ukugeleza kwezimali kungase kwabelwa ngokungafanele kumaphrojekthi anikeza kuphela ukuncipha kokukhipha intuthuko yesikhashana kuyilapho kuqiniswa ukuncika kukaphethiloli wesikhathi eside. Izimiso Ezijwayelekile ziqinisekisa ukuthi izikhungo zezimali zibeka phambili ukutshalwa kwezimali kwesimo sezulu esimeme ngempela. Izimiso Ezibalulekile Zokulandelelwa Kwezimali Zokunciphisa Isimo Sezulu Izimiso Ezivamile zihlukanisa izimali zokunciphisa isimo sezulu zibe ngamaqembu amathathu ahlukene, iqinisekisa ukuthi ukutshalwa kwezimali kuhambisana neSivumelwano SaseParis futhi kufaka isandla emnothweni womhlaba onemvelo. 1. Imisebenzi Emibi-noma Ephansi Kakhulu Yokukhipha Umoya Ukuze kuzuzwe ikusasa elingenaziro, ukutshalwa kwezimali kufanele kubeke phambili amaphrojekthi akhiqiza kancane noma angabikho ukukhishwa kwesisi esibamba ukushisa kuyilapho enikela ngenkuthalo ekususweni kwekhabhoni ejulile. Le misebenzi ihambisana ngokugcwele nokuhlosiwe kwesimo sezulu somhlaba wonke futhi imele izindlela eziphumelela kakhulu eziya ekusimameni kwesikhathi eside. Izindawo ezibalulekile zokutshalwa kwezimali zihlanganisa amandla avuselelekayo, afana nelanga, umoya, amandla aphehlwa ngamanzi, kanye ne-geothermal, athatha indawo yamafutha ensalela futhi anikeze ugesi ohlanzekile, osimeme. Ukwengeza, amaphrojekthi okudliwa kwekhabhoni—okuhlanganisa ukutshalwa kabusha kwamahlathi, ukubuyiselwa kwekhabhoni yenhlabathi, kanye nezinhlelo zekhabhoni eluhlaza okwesibhakabhaka (isb., ukubuyisela imihlume notshani basolwandle)—ukusiza ukususa i-CO₂ emkhathini. Intuthuko eyengeziwe ekukhiqizeni izimboni ezinekhabhoni ephansi nayo ibalulekile. Ubuchwepheshe obufana ne-hydrogen eluhlaza, usimende we-carbon-negative, kanye ne-bioplastics kunikeza ezinye izindlela ezisebenzayo ezintweni zendabuko, ezikhishwa kakhulu, ezinciphisa umthelela wemvelo wezimboni ezibalulekile. Lawa maphrojekthi akha isisekelo somnotho ovumelana nesimo sezulu futhi aqinisekisa ukuthi ukutshalwa kwezimali kwezezimali kuqhuba ushintsho lwangempela, oluhlala njalo olubheke emhlabeni osimeme. Lawa maphrojekthi ahambisana ngokugcwele nezinhloso ze-net-zero futhi aqhubekisela phambili ukukhishwa kwekhabhoni okujulile. Izibonelo zifaka: 2. Imisebenzi Yezinguquko Nakuba inhloso enkulu kuwumnotho okhishwe ngokuphelele, ezinye izimboni nezinhlelo zidinga isigaba esimaphakathi ukuze kuncishiswe intuthu ekhishwayo ngaphambi kokuzuza ukusimama okuphelele. Imisebenzi yezinguquko idlala indima ebalulekile kule nqubo ngokwenza ngcono ukusebenza kahle kwengqalasizinda ekhona kuyilapho kuncishiswa ukuthembela kumafutha ezinto ezimbiwa phansi. Kodwa-ke, la maphrojekthi kumele aphathwe ngokucophelela ukuze agweme ukukhiya kwekhabhoni isikhathi eside futhi aqinisekise ukuthi asebenza njengezitebhisi eziya ezixazululweni ze-net-zero. Amasu abalulekile ezinguquko ahlanganisa ukuthuthukiswa kokusebenza kahle kwamandla ezimbonini, okunganciphisa ukukhishwa kwegesi ngo-30-50% ngobuchwepheshe obuthuthukisiwe obufana nokubuyiswa kokushisa okulahlwayo, ukuzenzekelayo, kanye nezinqubo zokukhiqiza ezonga amandla. Emkhakheni wezokuthutha, ukutholwa kwezimoto eziyingxubevange kunikeza isisombululo sesikhashana, ukwehlisa ukungcola ngenkathi kuvula indlela yokufaka ugesi ogcwele kanye nokuhamba okune-hydrogen-powered. Ukwengeza, ukulungisa kabusha izakhiwo ezinezixazululo ezonga amandla, njengamaphampu okushisa, uphahla oluluhlaza, nokuhlanganiswa kwegridi ehlakaniphile, kusiza ukunciphisa ukusetshenziswa kwamandla kanye nezinyathelo zekhabhoni. Ngokuqinisekisa ukuthi imisebenzi yezinguquko ihlala ihambisana nezinjongo zesikhathi eside zokususa ikhabhoni, ukutshalwa kwezimali kwezimali kungakhuphula izinzuzo zesimo sezulu kuyilapho kusheshisa ukushintshela emhlabeni wonke kumandla esimeme, ezokuthutha, nezimboni. Lawa maphrojekthi anciphisa ukungcola ezinhlelweni ezikhona kodwa asabandakanya ukuthembela kumafutha ezinto ezimbiwa phansi. Akumele badale ukukhiya kwekhabhoni yesikhathi eside. Izibonelo zifaka: 3. Imisebenzi Evumelayo Ukuzuza umnotho ongekho ezingeni eliphelele akudingi nje kuphela ukuncishiswa kwesisi esiphumayo esiqondile kodwa nohlelo oluqinile lokusekela oluvumela ukwamukelwa okusabalele kobuchwepheshe nezinqubo ezihambisana nesimo sezulu.
