"Izinyathelo Zokuphatha Zokuhweba Nge-Carbon Emissions (Isivivinyo)" zizoqala ukusebenza ngomhla ka-1st.Feb, 2021. Uhlelo Lwezwe Lokuhweba Lokukhishwa Kwekhabhoni YaseChina (Imakethe Yezwe Yekhabhoni) luzosebenza ngokusemthethweni.Imboni kasimende ikhiqiza cishe u-7% wokukhishwa kwekhabhoni dioxide emhlabeni jikelele.Ngo-2020, ukukhiqizwa kukasimende waseShayina kungamathani ayizigidi eziyizinkulungwane ezingu-2.38, okubalelwa ngaphezu kwama-50% okukhiqizwa kukasimende emhlabeni jikelele.Ukukhiqizwa nokudayiswa kukasimende nemikhiqizo ye-clinker kukleliswe kuqala emhlabeni iminyaka eminingi.Imboni kasimende yaseShayina iyimboni esemqoka ekukhiqizweni kwekhabhoni dayokhsayidi, ibalwa ngaphezu kwe-13% yokukhipha isikhutha sezwe.Ngaphansi kwesizinda se-carbon peak kanye nokungathathi hlangothi kwe-carbon, imboni ye-cement ibhekene nezinselele ezinzima;ngasikhathi sinye, imboni kasimende yenze umsebenzi onjengokufaka uphethiloli ongahluziwe, ukonga amandla kanye nokunciphisa ikhabhoni, kanye nokuzithiba kwemboni ukuze iqhubeke ithuthukisa izinga lemvelo.Leli elinye ithuba lentuthuko yezinga eliphezulu neqhubekayo yemboni.
Izinselele ezinzima
Imboni kasimende iyimboni ejikelezayo.Imboni kasimende iyisizinda sokuthuthukiswa komnotho kazwelonke.Ukusetshenziswa kukasimende nokuphumayo kuhlobene eduze nomnotho kazwelonke kanye nentuthuko yezenhlalakahle, ikakhulukazi ukwakhiwa kwengqalasizinda, amaphrojekthi amakhulu, izakhiwo zokutshalwa kwempahla ezingaguquki, kanye nezimakethe zasemadolobheni nezasemaphandleni.Usimende unokuphila okufushane kweshelufu.Ngokuyisisekelo, abahlinzeki bezindawo zikasimende bakhiqiza futhi bathengise ngokuya ngesidingo semakethe.Isidingo semakethe sikasimende sikhona ngendlela eqondile.Uma isimo somnotho sisihle futhi isidingo semakethe sinamandla, ukusetshenziswa kukasimende kuzokhula.Ngemva kokuphothulwa kokwakhiwa kwengqalasizinda kanye namaphrojekthi amakhulu aqaliswa ngokulandelana, lapho umnotho kazwelonke waseShayina kanye nomphakathi usufinyelele esigabeni esivuthiwe, isidingo sikasimende ngokwemvelo sizongena enkathini yethafa, kanti ukukhiqizwa kukasimende okuhambisanayo nakho kuzongena esikhathini sethafa.Isinqumo semboni sokuthi imboni kasimende ingafinyelela iziqongo zekhabhoni ngo-2030 asihambisani kuphela nesiphakamiso esicacile sikaNobhala Jikelele u-Xi sokuzuza iziqongo zekhabhoni ngo-2030 kanye nokungathathi hlangothi kwekhabhoni ngo-2060, kodwa futhi nejubane lokulungiswa kwesakhiwo sezimboni zikasimende nemakethe. .
Amathuba
Njengamanje, ukusetshenziswa kwamandla kanye nokukhishwa kwe-carbon dioxide ngeyunithi ngayinye ye-GDP kwehliswe ngo-13.5% no-18% ngokulandelana, okufakwe ezinhlosweni eziyinhloko zokuthuthukiswa komnotho nezenhlalakahle phakathi nesikhathi "soHlelo Lweminyaka Emihlanu".Njengamanje, uMkhandlu Wombuso kanye neminyango ethintekayo iphinde yakhipha uchungechunge lwemibhalo yenqubomgomo efanele efana ne-green and low-carbon, ukuguquka kwesimo sezulu kanye nokuhweba nge-carbon emission, okunomthelela omuhle kakhulu embonini kasimende.
Ngokuthuthuka kwe-carbon peak kanye nokungathathi hlangothi kwekhabhoni, imboni kasimende izohlanganisa ngokugcwele izidingo zokuthuthukiswa kanye nezokwakha zezikhathi ezahlukahlukene, ilungise ukukhiqizwa kukasimende nokuhlinzekwa ngokwezidingo zemakethe, futhi kancane kancane yehlise umthamo wokukhiqiza ongasebenzi kahle ngesisekelo sokuqinisekisa ukutholakala kwemakethe.Lokhu kuzosheshisa ukuqedwa kwamandla okukhiqiza aphelelwe yisikhathi embonini kasimende, kuqhubeke nokuthuthukisa ukwakheka kwamandla okukhiqiza.Futhi amabhizinisi ayaphoqeleka ukuthi aguqule futhi athuthukise, asebenzise ubuchwepheshe obusha kanye nemishini ukuze kuthuthukiswe ukongiwa kwamandla kanye namazinga okunciphisa ukungcola, ukuthuthukisa ukwabiwa kwezinsiza, nokukhuthaza ukuthuthukiswa kwekhwalithi nokusebenza kahle.Ukwethulwa kwezinqubomgomo ezihlobene neziqongo zekhabhoni kanye nokungathathi hlangothi kwekhabhoni nakho kuzosiza ekukhuthazeni ukubambisana phakathi kwamabhizinisi, ukuhlanganiswa nokuhlelwa kabusha, njll. Ngokuzayo, izinzuzo zamaqembu amakhulu zizobonakala kakhulu.Bazophinde baqinise ukusungulwa kwezobuchwepheshe, bakhulise izinga lokushintsha izinto ezingavuthiwe kanye namafutha, babambe iqhaza kakhulu ekuphathweni kwempahla ye-carbon, futhi banake kakhulu ubuchwepheshe bokonga amandla nokunciphisa ukungcola, izimakethe zekhabhoni, izimpahla zekhabhoni nolunye ulwazi, ukuze kwandiswe ukuncintisana kwezimakethe.
Izinyathelo zokunciphisa ikhabhoni
Njengamanje, zonke izinkampani zikasimende zasekhaya sezamukele ubuchwepheshe obusha bokukhiqiza okomile, obusezingeni eliphezulu lamazwe ngamazwe lilonke.Ngokohlaziyo lwesimo samanje semboni, imboni kasimende inendawo elinganiselwe yokunciphisa ikhabhoni ngobuchwepheshe obukhona bokonga ugesi kanye nobunye ubuchwepheshe bempahla eluhlaza ye-limestone (ngenxa yokusetshenziswa okukhulu nezinye izinsiza ezilinganiselwe).Esikhathini esibucayi seminyaka emihlanu ezayo, isilinganiso sokuncishiswa kokukhishwa kwekhabhoni ngeyunithi ngayinye kasimende sizofinyelela ku-5%, okudinga imizamo emikhulu.Ukuze kuzuzwe umgomo wokungathathi hlangothi kwekhabhoni kanye ne-CSI ukuze kuzuzwe ukuncishiswa kwekhabhoni ngama-40% ngeyunithi ngayinye kasimende, ubuchwepheshe obuphazamisayo buyadingeka embonini kasimende.
Kunezincwadi eziningi nezibuyekezo embonini ezidingida ukuncishiswa kwekhabhoni ngobuchwepheshe okonga amandla.Ngokusekelwe ekuthuthukisweni kwemboni kasimende nokhonkolo kanye nezimo zikazwelonke, abanye ochwepheshe baxoxisane futhi bafingqa izinyathelo ezibalulekile zokunciphisa i-emissions yemboni kasimende:ukusetshenziswa kwesayensi nokusebenza kahle kukasimende ngokulungisa ukwakheka kwemikhiqizo usimende;ukuqinisa ukwakheka kwezinga eliphezulu, kanye nokwenza kahle izibopho zabakhiqizi nabathengi” izindlela zokubala ezikhishwa yikhabhoni kanye nezindlela ezahlukene zokwabiwa kwezikweletu.
Okwamanje isesikhathini sokulungiswa kwenqubomgomo.Ngokuthuthukiswa kwenani eliphakeme lekhabhoni nomsebenzi wokungathathi hlangothi kwekhabhoni, iminyango efanele yethule ngokulandelana ukulawulwa kokungcoliswa kwekhabhoni kanye nezinqubomgomo zezimboni ezihlobene, amasu kanye nezindlela zokunciphisa ukungcola.Imboni kasimende izoletha isimo sokuthuthuka esizinzile, ukuze iqhube inani elikhulu lezimpahla zokonga ugesi nezokuvikela imvelo kanye nezimboni eziphathelene nezinsizakalo ezihambisanayo.
