Phakathi kwezixwayiso zokuthi ukuhlukahluka kwemvelo kusengozini, abaholi bezemvelo bahlangane eMontreal ukuze basungule izindlela ezihloselwe ukuhlanganisa umhlaba nemvelo yasolwandle futhi baqhamuke namashumi ezigidigidi zamaRandi ukuze kuxhaswe imizamo yokongiwa kwemvelo.

Izithunywa ezivela emazweni angaba yi-190 zahlangana engqungqutheleni yamasonto amabili ukuze kuphothulwe uhlaka lokuvikela amaphesenti angama-30 omhlaba kanye nezindawo zasolwandle ngonyaka wezi-2030. Njengamanje, u-17% wezindawo ezisemhlabeni kanye no-10% wezindawo zasolwandle zivikelekile.
Uhlaka oluhlongozwayo luphinde lucele ukuthi kwehliswe izinga lokusungulwa nokusungulwa kwezinhlobo zezilwane ezihlaselayo ngama-50%, kunqanyulwe ukusetshenziswa kwezibulala-zinambuzane ngesigamu, futhi kuqedwe ukulahlwa kukadoti wepulasitiki.
Imigomo – ebaluleke kakhulu kunangaphambili okungakafinyelelwanga kuyo – kulindeleke ukuthi ibe wumgogodla wenkulumo-mpikiswano yomhlangano. Kodwa akusekude emuva kuzoba nodaba lwezezimali, njengoba amazwe asathuthuka okungenzeka aphushele izibopho ezibalulekile zezimali ngaphambi kokusayina noma yisiphi isivumelwano.
