Ntawm lub rooj sib tham carbon, Tuam Tshoj (statista, 2022), uas nws cov pa roj carbon dioxide emissions los ntawm fossil fuels account rau 30 feem pua ntawm lub ntiaj teb no tag nrho nyob rau hauv 2020, tau cog lus tias yuav ncav cuag cov pa roj carbon ncov ua ntej 2030 thiab ua tiav carbon neutrality los ntawm 2060 (Zhou, 2021). Qhov cuam tshuam ntawm lub hom phiaj ntawm lub hom phiaj no tau nthuav tawm txhua yam ntawm tib neeg, xws li kev nom kev tswv, kev ruaj ntseg hauv tebchaws, kev lag luam, zej zog, ib puag ncig, kev ua neej, tib neeg thiab kev ua yeeb yam, thiab tau koom nrog ob qho tib si khoom siv thiab tsis yog khoom ntawm lub neej.
Raws li kev kwv yees ntawm cov khaub ncaws cuam tshuam lub koom haum thiab World Resources Institute, cov pa roj carbon hneev taw ntawm kev zam thiab textile kev lag luam yuav nce ntau dua 50 feem pua los ntawm 2030, thiab nws cov kev cuam tshuam ntau dhau rau ib puag ncig yuav tsum tau tswj. Raws li lub ntiaj teb cov chaw tsim khoom lag luam loj tshaj plaws, Tuam Tshoj txoj kev lag luam textile yuav tsum tau ua ib feem loj ntawm lub luag haujlwm rau cov pa roj carbon ntau ntxiv (Lin & moubarak, 2013). Xav txog qhov xwm txheej tam sim no, ntawm United Nations Climate Change Conference (cop26) hauv 2021, climate action Charter ntawm kev lag luam zam tau hu rau nws 130 tus neeg kos npe los txuas ntxiv lawv txoj kev cog lus kom txo qis lawv cov emissions los ntawm 2030, tsis yog tsuas yog txo lawv. los ntawm 30 feem pua (Kent, 2021).
Hauv kev daws cov teeb meem carbon emission ntawm zam textile kev lag luam, ntau tus neeg koom nrog hauv kev lag luam saw tau siv ntau lub tswv yim. Txawm li cas los xij, cov kev tshawb fawb uas twb muaj lawm tsom ntau dua rau cov tswv yim hais txog cov dej num ntawm kev lag luam (xws li cov khoom siv raw, tsim thiab kev tsim kho, kev tsim khoom thiab kev tsim khoom, cov saw hlau, thiab lwm yam), thiab them nyiaj tsawg rau cov dej num hauv qab (xws li. muag, lag luam, siv thiab pov tseg) (Lenzen & Murray, 2010).
Ib qho ntawm cov laj thawj vim li cas cov kev tshawb fawb uas twb muaj lawm tsom rau cov dej ntws tawm yog tias lawv muaj kev sib raug zoo nrog cov pa roj carbon emissions. Piv txwv li, nws yog feem ntau ntseeg hais tias lub ntiaj teb no warming tshwm sim los ntawm carbon dioxide thiab lwm yam tsev xog paj gases yog ib qho tseem ceeb ua rau kom nce nqi ntawm raw cov ntaub ntawv, vim hais tias huab cua hloov muaj ib tug muaj zog kev puas tsuaj rau kev ua liaj ua teb thiab tsiaj txhu, qhov chaw industries ntawm ntuj. fiber ntau thiab tsiaj fiber (Harle li al., 2007; Friedman, 2021). Yog li ntawd, cov khoom siv raw hauv cov txheej txheem nce siab tau txais kev saib xyuas zoo hauv cov tswv yim txo cov pa roj carbon monoxide. Kev tsim khoom thiab kev tsim khoom yog lwm qhov txuas hauv cov dej ntws uas muaj kev txhawj xeeb dav. Nws muaj feem cuam tshuam ncaj qha rau kev siv hluav taws xob, thiab feem ntau ntawm nws yog los ntawm cov thee thiab lwm yam fossil fuels nrog cov pa roj carbon ntau. Tsis tas li ntawd, kev txhim kho cov pob tshab ntawm kev yuav khoom thiab cov saw hlau kuj yog ib qho kev siv ntau thiab tau txais kev qhuas txog kev txo cov pa roj carbon emissions (Parker, 2022). Nws tsim cov cuab yeej ntsuas, xws li higg Performance index (tsim los ntawm cov khaub ncaws ruaj khov hauv xyoo 2011), qhia cov neeg siv khoom kom muaj nuj nqis ntawm txhua qhov txuas ntawm cov khoom lag luam muaj txiaj ntsig ntawm ib puag ncig thiab tib neeg raws li tus qauv, thiab ua kom pom kev lag luam ( gon ç Alves & Silva, 2021).
Lwm qhov laj thawj tseem ceeb rau kev tsom mus rau cov tswv yim sab saud yog tias cov pa roj carbon emissions ntawm cov dej ntws mus rau hauv cov dej ntws tau ntau dua rau ntawm macro scale, uas ua rau nws yooj yim rau kev taug qab thiab ntsuas, piv txwv li, los ntawm kev sau cov khoom siv hluav taws xob hauv cov txheej txheem tsim khoom lossis fiber ntau cov txheej txheem (Lenzen & Murray, 2010). Txawm li cas los xij, txawm hais tias cov pa roj carbon emissions los ntawm cov dej ntws hauv qab kuj tseem loj heev, lawv feem ntau tawg mus rau hauv micro qhov chaw uas nyuaj rau kev txheeb xyuas kom raug. Piv txwv li, nyob rau hauv qhov kev pom ntawm ntau yam kev hloov pauv hauv cov txheej txheem ntxhua khaub ncaws, nws yog qhov nyuaj rau kev ntsuas, taug qab lossis sib xyaw ua ke lub zog noj uas yuav tsum tau siv rau kev ntxuav khaub ncaws thaum hnav. Nws yog ib qho tseem ceeb uas yuav tsum tau muaj cov cuab yeej ntsuas ntsuas kom raug thiab ua tau zoo kom muaj nuj nqis ntawm cov pa roj carbon emissions los ntawm decentralized micro qhov chaw ntawm cov dej ntws. Yog li ntawd, tam sim no lub tswv yim decarbonization feem ntau tshwm sim hauv cov dej ntws ntws, suav nrog kev txhawb nqa pob tshab hauv kev yuav khoom thiab cov saw hlau, txo nws qhov cuam tshuam, thiab txwv tsis pub muaj peev xwm tsim khoom thiab nqi zog. Txawm li cas los xij, yog tias tsoomfwv thiab cov koom haum ntawm txhua lub tebchaws xav ua kom tiav lawv cov lus cog tseg kom txo cov pa roj carbon monoxide, lawv yuav tsum tsim cov tswv yim rau kev lag luam zam thiab textile tag nrho, thiaj li ua tib zoo saib xyuas cov tswv yim los daws cov pa roj carbon emissions ntawm cov dej ntws. .

Daim duab 1: lub neej voj voog ntawm cov khoom siv textile zam thiab qhov cuam tshuam ntawm txhua theem ntawm ib puag ncig (kev tawm tswv yim thiab tso tawm
Nws kuj tseem tau sau tseg tias feem ntau cov ntaub ntawv pom zoo tias lub tswv yim txo cov pa roj carbon monoxide yuav tsum tau txuas ntxiv mus rau qis qis "lub sijhawm siv tom qab", tshwj xeeb tshaj yog xav tias cov neeg siv khoom tus cwj pwm plays lub luag haujlwm tseem ceeb hauv cov pa roj carbon hneev taw tsim los ntawm kev siv cov khoom siv textile zam thiab qhov kawg ntawm tag nrho lub neej voj voog (Rotimi, topple & Hopkins, 2021). Daim duab 1 qhia txog qhov muaj peev xwm cuam tshuam ntawm kev tawm tswv yim thiab cov khoom lag luam textile zam ntawm ib puag ncig ntawm ntau theem. Nws qhia tau hais tias yuav ua li cas txhua theem ntawm lub neej voj voog ntawm cov khoom zam cuam tshuam rau ib puag ncig, suav nrog kev noj cov khoom siv ib puag ncig (xws li dej siv los sau cov ntaub ntawv raw, fossil fuels siv rau cov khoom siv hluav taws xob, thiab lwm yam) thiab cov khoom tso tawm rau ib puag ncig. (xws li carbon dioxide emissions los ntawm hlawv fossil fuels, pov tseg pov tseg tom qab cov khoom tiav, thiab lwm yam).
