I-2021 unyaka nonyaka, intlangano yophando lwezobhedu lwamazwe ngamazwe (i-ICSG) yabika ngoSeptemba 23 ukuba imveliso yobhedu ecocisiweyo yehlabathi ukususela ngoJanuwari ukuya kuJuni yayiyi-3.2% ngonyaka, ukuveliswa kobhedu lwe-electrolytic (kuquka i-electrolysis kunye ne-electrowinning) yi-3.5 I-% ephezulu kunaleyo yaloo nyaka, kwaye imveliso yobhedu ehlaziyiweyo eveliswe kwinkunkuma yobhedu yi-1.7% ngaphezulu kwaloo nyaka mnye.Imveliso yobhedu esulungekisiweyo yaseTshayina inyuke ngeepesenti ezi-6 kwisithuba sikaJanuwari-Juni ukusuka kunyaka ongaphambili, ngokwamanani asemthethweni okuqala.Imveliso yobhedu esulungekisiweyo yaseChile yayingaphantsi nge-7% kunexesha elifanayo kulo nyaka uphelileyo, ubhedu olusulungekileyo lwe-electrolytic lunyuke nge-0.5%, kodwa ubhedu lwe-electrorefining lwehle nge-11%.E-Afrika, ukuveliswa kobhedu olusulungekileyo kwi-Democratic Republic of the Congo kunyuke nge-13.5 yeepesenti ngonyaka njengoko iimigodi ezintsha zobhedu zavulwa okanye izityalo ze-hydrometallurgical zanda.Ukuveliswa kobhedu olusulungekisiweyo eZambia kunyuke ngeepesenti ezili-12 njengoko abanyibiliki benyibiliki bephinda bafunyanwa kukuvalwa kwemveliso kunye neengxaki zokusebenza ngo-2019 nasekuqaleni kuka-2020. ibonise ukwehla kwemveliso eBrazil, eJamani, eJapan, eRashiya, eSpain (SX-EW) naseSweden ngenxa yezizathu ezahlukeneyo, kubandakanywa ukuvalwa kokugcinwa, iingxaki zokusebenza kunye nokuvalwa kwezityalo ze-SX-EW.
