Ko te ahumahi taputapu kaainga i whakakorea katoatia te R22 refrigerant ki te tatau
E ai ki te Kawa o Montreal, kua aukatihia te whakamahana R22 i nga whenua whakawhanake, ka taea tonu te whakaputa ki nga whenua whakawhanake, engari ko te wa mutunga o te hanga me te whakamahi ko te 2030.
I te Hanuere 26, 2021, i tukuna e te Manatu o te Rauropi me te Taiao te Panui mo te Tukunga o 2021 Whakangao, Whakamahi me te Kawemai mo nga Taonga Ozone Depleting Substances (i muri nei ka kiia ko te Panui). E ai ki te Ture o te Repupirita Tangata o Haina mo te Aukati me te Whakahaere i te Parahanga Hau, Nga Ture mo te Whakahaere i nga Matū ka Whakakore i te Ozone Layer me etahi atu waahanga e pa ana, ka tukuna nga umanga 20 me te motunga whakaputa o te 292,795 tone hydrochlorofluorocarbons ( HCFC) i te 2021, ka tukuna e 46 nga waeine me te motunga whakamahi 31,726 tone hydrochlorofluorocarbons i te tau 2021.
Ka whakatauritea ki te 2020, ko te motunga whakaputa o te hydrochlorofluorocarbons (HCFCS) tae atu ki te HCFC-22 ka noho kare i rereke i te 2021, i te mea ka tino whakahekehia te motunga whakamahi, ka whakakorea ano te HCFCS i te umanga taputapu kaainga o Haina.
Ko te motunga hanga hCFC (HCFC) ka tukuna mo te hCFC-141B, HCFC-142B, HCFC-22, HCFC-123, HCFC-124 me HCFC-133A. I roto ia ratou, ko te HCFC-141B he kaihoko pupuhi e whakamahia ana i roto i te pouaka whakamahana me te ahumahi whakamahana wai. I te mea kua whakahouhia te punaha pahuka i roto i te umanga pouaka whakamātao ki te HFC-245FA + cyclopentane foming system, a, i te Hanuere 1, 2019, kua whakakorehia e te ahumahi whakamahana wai te whakamahi i te HCFC-141B. He iti ake te whakamahi a Hcfc-141b i roto i te umanga taputapu kaainga. Ko te tapeke mo te whakaputanga mo te hCFC-141B i te tau 2021 he 50,878 tana, kaore i rereke mai i te 2020.
Ka whakaritea ki te motunga whakaputa mo HCFC-22, ko te tapeke mo te whakamahi mo te hCFC-22 i roto i te umanga whakaahuru hau kainga i te tau 2021 ko te 31,726 tone, he hekenga o te 3,489 tone mai i te 35,215 tone i te tau 2020. He hononga tata tenei ki te whakawhiti pouaka whakamahana i roto. te ahumahi hau hau whare. Ko te wahanga o te maakete a HCFC-22 i roto i te umanga whakaahuru hau kainga e tata ana ki te 20% i te tau 2019, a ka heke haere tonu tenei wahanga i te tau 2020. He nui nga whakatutukitanga a te umanga whakaahuru hau o Haina ki te whakakore i te HCFC-22.
Ko te rautaki whakahaere a te HCFC-22 mo te umanga whakamahana hau o roto o Haina mai i te 2021 ki te 2026 kua whakaaetia e te Komiti Whakahaere o te Putea Maha, a kua whakapau kaha ki te whakakore i te 70% o te kai hCFC-22 hei te 2026, e he nui ake i te mea e hiahiatia ana e te Kawa Kawa o Montreal ki te whakatutuki i nga whakahekenga hCFC-22. Ka nui ake o matou koha ki te whakatinana a Haina i te Kawa Montreal.
