Raws li cov kws tshawb fawb, hnav ib nkawm khau ceev ceev ib zaug tsuas yog tsim 2.5 kg ntawm carbon dioxide, uas sib npaug rau kev tsav tsheb 6.4 km hauv lub tsheb tsis siv roj, sau "Daily Mail".
Fast fashion yog ib lo lus siv los piav txog cov txheej txheem ntawm kev tsim sai sai thiab muag pheej yig, zam khaub ncaws kom ua tau raws li qhov xav tau.
Cov kws tshawb fawb los ntawm Guangdong University of Technology hauv Suav teb tau tshuaj xyuas lub neej voj voog ntawm ib khub ntawm Levi's ris, los ntawm kev cog qoob loo ntawm paj rwb mus rau nws qhov kawg pov tseg los ntawm incineration.
Lawv pom tias tej khub tsuas hnav xya zaus xwb. Qhov no tsim nyog lawv li "fast fashion". Lawv tawm 11 npaug ntau dua carbon dioxide ntau dua li cov ris tsho hnav ntau dua.
"Raws li cov khaub ncaws hnav khaub ncaws niaj hnub, ib khub ntawm ris tsho hnav ris tsho muaj qhov cuam tshuam loj heev rau ib puag ncig, "hais tias Dr Ya Zhou, tus thawj coj ntawm kev tshawb fawb.
Cov kws tshawb fawb pom tias cov pa roj carbon hneev taw ntawm cov ris tsho hnav ris tsho yog 95-99% ntau dua li cov ris tsho hnav tsoos tsho, uas hnav qhov nruab nrab ntawm 120 zaug. Qhov sib txawv loj tshaj plaws ntawm ob hom kev noj yog tias cov khaub ncaws muag rau kev zam ceev yog thauj sai dua thiab hnav tsawg dua ua ntej muab pov tseg.
"Hloov cov qauv zam ua rau tib neeg yuav khaub ncaws ntau zaus thiab hnav lawv rau lub sijhawm luv luv kom ua raws li cov qauv tshiab," ntxiv Dr Zhou.
"Kev siv ntau dhau ua rau muaj kev nce ntxiv hauv kev siv cov peev txheej thiab lub zog hauv kev lag luam tsoos tsho los ntawm kev ua kom tag nrho cov khaub ncaws xa khoom, suav nrog kev tsim khoom, kev thauj mus los, kev siv thiab pov tseg, yog li ua kom muaj kev cuam tshuam ntawm kev lag luam tsoos tsho ntawm kev hloov huab cua " .
Cov kws tshawb fawb kwv yees tias ib khub ntawm cov ris tsho ua rau lub khw muag khoom ib txwm ua rau 0.22 kg ntawm carbon dioxide. Lub caij no, cov kws tshawb fawb kwv yees tias cov ris tsho muag hauv cov khw muag khoom ceev ceev emit 11 npaug ntau dua emissions.
Tsis zoo li niaj hnub zam, feem ntau ntawm cov emissions nyob rau hauv ceev zam yog los ntawm zus tau tej cov ris ntauv txhav thiab fibers, uas account rau 70% ntawm tag nrho cov emissions.
Cov emissions ntxiv yog feem ntau yog los ntawm kev thauj mus los ntawm cov ris tsho los ntawm cov chaw tsim khoom rau cov neeg siv khoom, uas suav txog 21% ntawm tag nrho cov emissions.
Vim tias cov qauv kev thauj mus los sai yog feem ntau los ntawm huab cua, 59 npaug ntau dua carbon dioxide tawm.
Raws li cov kws tshawb fawb, cov khoom lag luam nrawm nrawm tshaj tawm cov ntawv sau tshiab 25 zaug sai dua li cov qauv zam, ua rau luv luv zam cycles thiab hyperconsumption. Qhov no tsim cov khoom pov tseg loj heev thiab cov pa phem ntau ntau.
Nws tau kwv yees tias kev lag luam zam tsim 10% ntawm tag nrho lub ntiaj teb lub tsev cog khoom emissions thiab kwv yees li 92 lab tons ntawm pov tseg txhua xyoo.
Feem ntau ntawm cov pov tseg no raug thauj mus rau cov tebchaws xws li Guatemala, Chile thiab Ghana, qhov chaw pov tseg loj tau ua rau "kev puas tsuaj ntawm ecological thiab kev sib raug zoo".
Hmoov zoo, cov kws tshawb fawb hais tias muaj ntau txoj hauv kev los txo qis kev lag luam cov pa roj carbon hneev taw.
Kev yuav khaub ncaws los ntawm cov khw muag khaub ncaws thib ob hauv offline txo cov pa roj carbon hneev taw ntawm ob lub ris tsho los ntawm 90%. Thiab cov ris tsho uas dhau los ntawm cov khw muag khoom noj khoom haus tau hnav 127 zaug hauv lawv lub neej.
Cov kws tshawb fawb tseem qhia tias kev rov ua dua cov ris tsho los yog siv cov khaub ncaws xauj tsev tuaj yeem txo cov pa roj carbon hneev taw ntawm ib qho hnav los ntawm 85 thiab 89%, feem.
