Ua hoʻopau loa ka ʻoihana mea hana hale i ka pahu hau R22 i ka helu ʻana
Wahi a ka Montreal Protocol, ua hooki ʻia ka mea hoʻoheheʻe R22 i nā ʻāina i kūkulu ʻia a hiki ke hana ʻia i nā ʻāina e ulu nei, akā ʻo 2030 kāna hana a hoʻohana.
Ma Ianuali 26, 2021, ua hoʻopuka ka Ministry of Ecology and Environment i ka Hoʻolaha e pili ana i ka hoʻopuka ʻana o 2021 Production, Use and Import Quotas for Ozone Depleting Substances (i kapa ʻia ʻo ka Notice). Wahi a ke Kānāwai o ka People's Republic of China e pili ana i ka pale ʻana a me ka mālama ʻana i ka hoʻohaumia ʻana o ka ea, nā kānāwai e pili ana i ka mālama ʻana i nā mea e hoʻopau ai i ka Ozone Layer a me nā mea ʻē aʻe e pili ana, e hoʻopuka ʻia nā ʻoihana 20 me kahi quota hana o 292,795 tons o hydrochlorofluorocarbons ( HCFC) i 2021, a e hoʻopuka ʻia nā ʻāpana he 46 me ka quota hoʻohana o 31,726 tons o hydrochlorofluorocarbons i 2021.
Hoʻohālikelike ʻia me 2020, e hoʻololi ʻole ʻia ka quota hana o hydrochlorofluorocarbons (HCFCS) me HCFC-22 i ka makahiki 2021, ʻoiai e hoʻemi nui ʻia ka hoʻohana ʻana, e hoʻopau hou i ka HCFCS i ka ʻoihana ʻenehana home o Kina.
E hoʻopuka ʻia ka ʻāpana hana hCFC-containing (HCFC) no hCFC-141B, HCFC-142B, HCFC-22, HCFC-123, HCFC-124 a me HCFC-133A. I waena o lākou, ʻo ka HCFC-141B kahi mea hoʻoheheʻe i hoʻohana ʻia i loko o ka friji a me ka ʻoihana hoʻomehana wai. No ka mea, ua hoʻonui ʻia ka ʻōnaehana huʻihuʻi i loko o ka ʻoihana pahu hau i ka HFC-245FA + cyclopentane foaming system, a ma Ianuali 1, 2019, ua pāpā loa ka ʻoihana hoʻomehana wai i ka hoʻohana ʻana o HCFC-141B. Ua hoʻohana liʻiliʻi ʻia ka Hcfc-141b i ka ʻoihana mea hana hale. ʻO ka huina hoʻonui hana no ka hCFC-141B ma 2021 he 50,878 tone, ʻaʻole i loli mai 2020.
Ke hoʻohālikelike ʻia me ka quota hana no HCFC-22, ʻo ka huina hoʻohana nui no ka hCFC-22 i ka ʻoihana ea ea home ma 2021 he 31,726 tons, he emi o 3,489 tons mai 35,215 tons i 2020. Pili loa kēia i ka hoʻololi refrigerant i loko. ka ʻoihana hoʻoheheʻe hale. ʻO ka māhele mākeke o nā ea ea HCFC-22 i ka ʻoihana ea ea home ma kahi o 20% i ka makahiki 2019, a e hoʻomau ka emi ʻana o kēia māhele i ka makahiki 2020.
Ua ʻae ʻia ka hoʻolālā hoʻokele HCFC-22 phase-out no ka ʻoihana ea ea ma Kina mai 2021 a 2026 e ke Kōmike Hoʻokō o ka Multilateral Fund, a ua hoʻohiki ʻo ia e hoʻopau i ka 70% o ka hoʻohana ʻana i ka hCFC-22 e 2026, ka mea. ʻoi aku ma mua o ka mea i koi ʻia e ka papa kuhikuhi Montreal Protocol e hoʻokō i nā hōʻemi hCFC-22. E hāʻawi hou aku mākou i nā haʻawina i ka hoʻokō ʻana o Kina i ka Montreal Protocol.
