Incopho yekhabhoni yaseTshayina kunye nezicwangciso zokungathathi hlangothi kwekhabhoni zijongana nobunzima kunye nemingeni efana nokunciphisa ukukhutshwa okubalulekileyo, imisebenzi yotshintsho enzima, kunye neefestile ezixineneyo.Injani inkqubela yangoku ye "dual carbon"?Amahlathi angenza njani igalelo elingakumbi ekuphumezeni umgangatho “wekhabhoni ezimbini”?KwiQonga leHlabathi laMazwe ngaMahlathi kunye neGrass Carbon Sink Innovation elisandul’ ukubanjwa, iintatheli zadlan’ indlebe neengcali ezifanelekileyo.
Eyona miba iphambili echaphazela ukufezekiswa kweenjongo zaseTshayina “zekhabhoni ezimbini” kukwakhiwa kwemizi-mveliso enzima, ubume bamandla obusekwe kumalahle, kunye nokusebenza kakuhle okuphantsi okubanzi.Ukongeza, i-China igcine kuphela iminyaka engama-30 ukuphumeza ukungathathi hlangothi kwekhabhoni, oku kuthetha ukuba kufuneka kuthathwe iinzame ezinkulu ukukhuthaza uphuhliso lwezoqoqosho nentlalontle kunye noguquko olupheleleyo lwamandla aluhlaza kunye nekhabhoni ephantsi.
Iingcali ezizimase intlanganiso zathi ukusebenzisa i-carbon peaking kunye nokungathathi hlangothi kwekhabhoni ukuqhuba iteknoloji entsha yaseTshayina kunye notshintsho lophuhliso luyimfuneko yendalo kuphuhliso loqoqosho nolwentlalo olukumgangatho ophezulu, imfuneko engenakuthintelwa yokhuseleko olukwinqanaba eliphezulu lokusingqongileyo kwendalo, kunye nethuba lembali. ukunciphisa umsantsa wophuhliso namazwe aphambili aphuhlileyo.Njengelona lizwe likhulu elisaphuhlayo kwihlabathi, ukuphunyezwa kwesicwangciso-qhinga saseTshayina “sekhabhoni ezimbini” kuya kwenza igalelo elibalulekileyo ekukhuseleni umhlaba welizwe.
"Ukusuka kwimibono yasekhaya nakwamanye amazwe, kufuneka sigcine ingqwalasela yobuchule ekufezekiseni i-carbon peak kunye nokungathathi hlangothi kwekhabhoni."UDu Xiangwan, umcebisi weKomiti yeSizwe yeeNgcali zoTshintsho lweMozulu kunye nomfundi weLungu le-CAE, uthe ukuphunyezwa kwesicwangciso se-"dual carbon" linyathelo.Ngokukhawulezisa inkqubela phambili yezobuchwepheshe kunye nokuguqulwa, sinokufikelela kwincopho yekhabhoni ephezulu kunye nokungathathi hlangothi kwekhabhoni kwishedyuli.
"Ngo-2020, iindawo zokugcina zaseTshayina eziQinisekisiweyo zamahlathi kunye neesinki zekhabhoni zengca ziya kuba yi-88.586 yeebhiliyoni zeetoni.Ngo-2021, amahlathi onyaka aseTshayina kunye neesinki zekhabhoni zengca ziya kudlula i-1.2 yeebhiliyoni zeetoni, zibekwe kwindawo yokuqala emhlabeni, utshilo uYin Weilun, isifundiswa seLungu le-CAE.Kunikelwa ingxelo yokuba kukho iindlela ezimbini eziphambili zokufunxa ikharbon diokside ehlabathini, enye ngamahlathi asemhlabeni, yaye enye yeyaselwandle.Inani elikhulu le-algae elwandle lifunxa i-carbon dioxide, ethi ke iguqulwe ibe ngamaqokobhe kunye ne-carbonates yokugcina ukujikeleza kwezinto kunye ne-metabolism yamandla.Amahlathi asemhlabeni anokuthi athathe ikhabhoni ixesha elide.Uphando lwezenzululwazi lubonisa ukuba kwikyubhiki mitha nganye yokukhula, imithi inokufunxa umlinganiselo weetoni ezisisi-1,83 zekharbon diokside.
Amahlathi anomsebenzi oqinileyo wokugcinwa kwekhabhoni, kwaye ukhuni ngokwawo, nokuba i-cellulose okanye i-lignin, yenziwe ngokuqokelela i-carbon dioxide.Ukhuni luphela luyimveliso yokuqokelelana kwekharbon diokside.Iinkuni zinokugcinwa amakhulu, amawaka, okanye iibhiliyoni zeminyaka.Amalahle agaywayo namhlanje aguqulwa ukusuka kwiibhiliyoni zeminyaka yokulungiswa kwamahlathi kwaye yi-carbon sink yokwenene.Namhlanje, umsebenzi wamahlathi waseTshayina awugxininisi nje ekuvelisweni kwamaplanga, kodwa nasekuboneleleni iimveliso zendalo, ukufunxa ikharbon diokside, ukukhupha ioksijini, ukulondoloza imithombo yamanzi, ukugcina umhlaba namanzi, nokucoca umoya.
