Ma Malaki 26, 2020, ua mālama pono ʻia ka hālāwai loiloi loea no ka palapala hoʻolālā o ka "Glass Industry Environmental Protection Research Institute, Chinese Academy of Environmental Sciences, China Daily Glass Association, China Fiberglass Industry Association, China Building Materials Research Institute, China Building Glass and Industrial Glass Association" (i kapa ʻia ma hope aku ʻo "Standard") ma Beijing ma ke ʻano o kahi hālāwai kūkā wikiō.

Ma ka hālāwai, ua hoʻolauna kikoʻī ka ʻāpana hana papahana i ke kumu o ka hoʻokumu ʻana o ke "kūlana", ka ʻike nui o ka ʻoihana, ka loiloi ʻenehana kaohi haumia, a me nā ʻike nui o ke kūlana. Ma hope o ka nīnau ʻana a me ke kūkākūkā ʻana, ua manaʻo ka hui loea ua piha nā mea i hāʻawi ʻia e ka ʻāpana hana papahana, piha i ka ʻike, a ua hoʻohālikelike ʻia ke ʻano, a ua hoʻoholo like i ka loiloi loea o ka palapala hoʻolālā "kūlana" no nā manaʻo. I ka manawa like, ua hāʻawi ʻia nā manaʻo no ka hoʻomaikaʻi hou ʻana o ke Kūlana.

Wahi a ka National "Eleventh Five-Year" National Environmental Protection Standards Plan (Huanfa [2006] No. 20), i mea e paipai ai i ka hoʻokō ʻana i ke kānāwai kaiapuni a me ka nānā ʻana a me ka hoʻokele ʻana e hoʻokō i ka ʻepekema, kānāwai a me ke kūlana maʻamau, hoʻomaikaʻi hou i nā kānāwai a me nā hoʻoponopono palekana kaiapuni, a hoʻomaikaʻi i ka palekana kaiapuni. ʻO nā hoʻoponopono loea a me ka ʻōnaehana maʻamau, i ka wā o ka "Eleventh Five-Year Plan", "... e hoʻonui i ka hana o ka hoʻokumu ʻana i nā kūlana hoʻokuʻu haumia ʻano ʻoihana, a hoʻopau i ka hana o ke kila, ka lanahu, ka hana mana wela, nā pesticides, nā metala non-ferrous, nā mea kūkulu hale, nā lāʻau lapaʻau, nā petrochemicals, nā kemika, ka petroleum. ʻO ka hoʻokumu ʻana a me ka hoʻoponopono hou ʻana i nā kūlana hoʻokuʻu haumia no nā ʻoihana koʻikoʻi e like me ke kinoea kūlohelohe, nā mīkini, ka paʻi lole a me ka hoʻoluʻu ʻana e hoʻonui i ka uhi ʻana o nā kūlana hoʻokuʻu e pili ana i ka ʻoihana a e hōʻemi mālie i ka laulā o ka hoʻopili ʻana i nā kūlana hoʻokuʻu haumia maʻamau...". I Iune 2007, ua hoʻopuka ka ʻOihana Hoʻomalu Kaiapuni o ka Mokuʻāina mua i ka Institute of Standards of the Chinese Academy of Environmental Sciences i kahi hoʻolālā hoʻolālā maʻamau no ka hoʻokumu ʻana o ka "Daily Glass Industry Pollutant Emission Standard" a me ka "Glass Fiber Industry Pollutant Emission Standard". Ua hoʻokō ke kime hoʻolālā maʻamau i ka hana hoʻolālā maʻamau e like me nā lula pili o ka hoʻolālā a me ka hoʻoponopono hou ʻana i nā kūlana palekana kaiapuni, a ua noi ākea i nā manaʻo mai ka lehulehu ma ʻApelila 12, 2011, Nowemapa 27, 2015, a me Iulai 12, 2018. I ʻOkakopa 2019, e like me nā koi o ke Keʻena o ke Kaiapuni Atmospheric o ke Kuhina o Ecology a me ke Kaiapuni, ua hoʻokumu ʻia ke "Emission Standard of Air Pollutants for the Flat Glass Industry" (GB 26453-2011), ke "Emission Standard of Air Pollutants for the Electronic Glass Industry" (GB 29495-2013) a me ka "Daily Glass Industry Pollutant Emission Standard" a me ka "Glass Fiber Industry Pollutant Emission Standard", a ua hoʻokumu ʻia ke "Glass Industry Air Pollutant Emission Standard".
