I roto i te wā e pāngia ana te ahumahi simitī o te ao e ngā pēhanga waro, i whakapuaki ngā tīma nō te École polytechnique fédérale de Lausanne (EPFL) me te Paul Scherrer Institute (PSI) i Suwīsera i tētahi rangahau pakari i te 18 Pipiri 2025 (CET): mā ngā algorima AI ka taea te hanga anō i ngā tohutao simitī i te taumata millisecond, ā, ka whakaitia te whakaputanga waro ki te 80% me te pupuri i te kaha me te whaihua ahumahi. I te tirotiro i ngā mano tini whakarōpūtanga rauemi, i whakaitihia te whai wāhitanga o te clinker (熟料) me te whakauru i ētahi kairau iti‑waro pērā i te ash wāhi ahi me te toka lime. I purongo a ScienceDaily, ka taea e tēnei auahatanga te whakaora i ngā miriona toni CO2 ia tau, ā, e ai ki ngā tatauranga ka whakaitia te tapuwae waro o te simitī o te ao neke atu i te 30% i te 2030. I mua i te hui COP30, ka titiro tēnei hua hei tauira mō te 'reorua kākāriki' ā‑AI, ā, kua kukume i te aro o ngā kamupene hangahanga nui pērā i LafargeHolcim.
Ko te whakaputa simitī te tuarua o ngā pūtake waro ahumahi nui rawa atu, e 8% pea o ngā whakaparitanga waro ā‑motu, ā, ka tukuna tata ki te 4 piriona toni CO2 ia tau, nō te kupu nā te tukanga uku wera clinker i ngā pānga pāmahana teitei (1450°C). I mua, ko te whakapai i ngā tohutao he mahi whakamātautau i te rōpū taiwhanga, he roa, he utu nui. Nā te tikanga o te tīma Huitirēra, i whakawhanake rātou i tētahi papa whakaahu i runga i te mīhini ako e taea ana te whakamātau mano mano momo tohutao i roto i ngā hēkona, e aromatawai ana i te kaha, te roa me te tapuwae waro. E ai ki te rangatira rangahau, te Kairangahau Matū o EPFL, a Emma Brun: 'Ehara te AI i te whakakapi i te tangata, engari he whakatere auahatanga — i kitea e mātou ngā tohutao iti‑waro e roa ana te roa ki te kitea mā ngā tikanga tuku iho.' Hei tauira, i whakaitia te rōrahi clinker mai i te 90% ki te 20%, ka whakakīhia ngā wāhanga mā ngā toenga ahumahi pērā i te fly ash; nā konei i heke te whakaputanga mai i te 900kg CO2 ia toni ki te 180kg, ā, ka tutuki te kaha pēhanga ki te 50MPa, e hāngai ana ki ngā paerewa ā‑ao.
Ko te angitu i ahu mai i te whakakotahitanga o ngā 'generative adversarial networks' (GAN) me te ako whakakaha (reinforcement learning, RL). I whakangungua te tauira i runga i ngā raraunga nui neke atu i ngā TB o ngā raraunga rauemi, tae atu ki ngā tohutao o mua me ngā raraunga taiao; ko te GAN te kaihanga i ngā tohutao pea, ā, mā te RL e hanga te mahi whakapai mā te whakamahi i tētahi tātaitai utu e whakarite ana mō te kaha me te iti waro. E ai ki te pepa i whakaputaina e Cosmos, he 1000 ngā wā tere ake te whaihua rorohiko atu i ngā tikanga ā‑tātaritanga tuku iho, ā, ka taea te whakahaere mā ngā GPU paerewa, he mea pai mō ngā pakihi rahi‑iti. I ngā whakamātautau taiwhanga, i pānuitia kua paahi ngā tohutao hou ki ngā whakamātautau tohu EN 197 ā‑tari o te EU, ā, he rite te roa ki te simitī tuku iho. I a Forbes e wetewete ana, ko tēnei hangarau ka taea te whakauru tika ki ngā raina whakaputa hei whakarerekē i ngā tohutao i te wā tūturu, ā, ka piki anō te whakaitinga waro e 20% pēnei i tā rātou tatauranga.
He whāinga nui tō te rangahau a Suwīsera ki te ao. E ai ki ngā tatauranga, ko ngā whakapūtanga waro o te umanga simitī e 90% o ngā whakapūtanga katoa o te rāngai hangahanga, ā, he 13% te tūnga o te rāngai hangahanga ki te GDP ā‑ao. I whakahua a Earth.Org, mā te whakamahi ā‑ao i ngā tikanga whakapai simitī mā te AI, ka taea e te ao te whakaiti neke atu i te 10 piriona toni CO2 tae noa ki te 2050 — āhua rite ki ngā whakapūtanga‑a‑tau o te EU. Kua tīmata te tīma ki te mahi ngātahi me te kamupene simitī nui o Suwīsera, Holcim, me te whakamahere mana mō tētahi raina whakamātautau i te 2026. I te pūrongo a Rinnovabili, ka taea te whakawhānuihia tēnei tauira ki te konga konokete me ngā papa whakarewa, ā, ka heke te tapuwae waro o ngā rauemi hanga katoa ki te 50%. I ngā whenua e whakawhanake ana pērā i India me Brazil, ka āwhina ngā taputapu AI ki te whakaiti utu mā te penapena rawa 10% me te tere ake i te panoni ki ngā 'whare kore‑waro'.
He wero anō e toe ana. I kupu a Interesting Engineering, ko te mana o ngā tauira AI e whakawhirinaki ana ki ngā raraunga kounga‑nui; mēnā he pānga ki ngā rauemi ā‑Europe anake ngā raraunga whakangungu, tērā pea kāore e hāngai ki ngā āhuatanga matatini o ngā whenua o Ahia. Waihoki, me whakatika ngā rārangi tuku rawa mō te whakamahi ahumahi; e ai ki ngā tatauranga, ko te wā hoki ki te whakahoki moni whakakahanga tuatahi he 2–3 tau pea. Kei te whakawhanake te tīma o EPFL i tētahi putanga tuwhera‑kōwhiringa (open‑source) hei karanga i ngā kairangahau o te ao kia tautoko i ngā raraunga, ā, kia whakatairanga i te whakamahi taurite.
Ehara tēnei rangahau i te wikitoria ā‑hao noa, engari he tauira hoki o te āhei o te AI ki te tautoko i ngā mahi āhuarangi. I kōrero a Brun i te kōrua pāpāho: 'I mua, ko te simitī te 'toa parauri'; mā te AI kua kāore e roa, kua huri ki te kākāriki.' I te whakatūpato o ngā Whāinga Whakawhanake Taurikore a te United Nations (SDG 9/13), tērā pea ka waiho tēnei 'reorua simitī AI' hei tauira ā‑ao ki te tautoko i te moemoeā 'waro‑kore' mō te 2050. Kei te huri haere te rāngai rauemi hanga, ā, kāore te AI e aro noa—ka noho hei pūtātara e hanga ana i te anamata.
