Zida zamadzi

Madzi abwino omwe anthu amakhala nawo ndi osowa kwambiri. Malinga ndi ziwerengero za bungwe la United Nations, kuchuluka kwa madzi padziko lapansi kuli pafupifupi ma kiyubiki kilomita 1.4 biliyoni, ndipo madzi amchere omwe amapezeka kwa anthu amangotenga 2.5% ya madzi onse, ndipo pafupifupi 70% ya iwo ndi. ayezi ndi matalala osatha m'mapiri ndi madera a polar. Madzi amadzimadzi amasungidwa pansi pa nthaka monga madzi apansi panthaka ndipo amapanga pafupifupi 97% ya madzi abwino omwe angakhalepo kwa anthu.

Kutulutsa mpweya

Malinga ndi kunena kwa NASA, kuyambira kuchiyambi kwa zaka za m’ma 1900, zochita za anthu zachititsa kuti mpweya wa carbon uchuluke kosalekeza komanso kutentha kwapang’onopang’ono kwa nyengo ya padziko lonse, zomwe zabweretsa mavuto ambiri monga: kukwera kwa madzi a m’nyanja, madzi oundana osungunuka ndi chipale chofeŵa. m'nyanja, kuchepetsa kusungirako madzi opanda mchere Kusefukira kwa madzi, mphepo zamkuntho, moto wolusa, ndi kusefukira kwa madzi kumachitika pafupipafupi komanso koopsa.

#Yang'anani pa kufunikira kwa mpweya wa carbon/madzi

Mayendedwe amadzi amayesa kuchuluka kwa madzi omwe amagwiritsidwa ntchito popanga zabwino kapena ntchito iliyonse yomwe anthu amadya, ndipo mawonekedwe a kaboni amayesa kuchuluka kwa mpweya wowonjezera kutentha womwe umatulutsidwa ndi zochita za anthu. Miyezo ya kaboni/madzi imatha kuyambira panjira imodzi, monga momwe zimapangidwira zinthu, kupita kumakampani kapena dera linalake, monga mafakitale a nsalu, dera, kapena dziko lonse. Kuyeza kuchuluka kwa mpweya wa carbon/madzi kumayang'anira kagwiritsidwe ntchito ka zinthu zachilengedwe komanso kuwunika momwe anthu amakhudzira chilengedwe.

#Kuyeza kuchuluka kwa kaboni/madzi pamakampani opanga nsalu, chidwi chimayenera kuperekedwa pagawo lililonse lazakudya kuti muchepetse kuchuluka kwa chilengedwe.

#Izi zikuphatikizapo momwe ulusi umakulidwira kapena kupanga, momwe amapota, kukonzedwa ndi kupakidwa utoto, momwe zovala zimapangidwira ndi kuperekedwa, komanso momwe zimagwiritsidwira ntchito, kuchapidwa ndikutayidwa.

#Zovuta zamakampani opanga nsalu pazamadzi ndi mpweya wa carbon

Njira zambiri zamafakitale opanga nsalu ndizomwe zimatengera madzi ambiri: kupanga, kukongoletsa, kupukuta, kuchapa, kupukuta, kusindikiza ndi kumaliza. Koma kugwiritsa ntchito madzi ndi gawo limodzi chabe la chilengedwe cha mafakitale a nsalu, ndipo madzi otayira opangira nsalu amathanso kukhala ndi zowononga zambiri zomwe zimawononga madzi. Mu 2020, Ecotextile adawonetsa kuti makampani opanga nsalu amawerengedwa kuti ndi amodzi mwa omwe amapanga mpweya wowonjezera kutentha padziko lapansi. Mpweya wamakono wotuluka m’nyumba zopanga nsalu wafikira matani 1.2 biliyoni pachaka, kupitirira kuchuluka kwa mayiko otukuka kumene amatulutsa. Zovala zimatha kuwerengera kuchuluka kwa mpweya woipa padziko lonse lapansi pofika chaka cha 2050, kutengera kuchuluka kwa anthu komanso momwe amagwiritsira ntchito. Makampani opanga nsalu akuyenera kutsogolera poyang'ana kwambiri mpweya wa carbon ndi kugwiritsa ntchito madzi ndi njira ngati kutentha kwa dziko ndi kutaya madzi ndi kuwonongeka kwa chilengedwe kudzakhala kochepa.

OEKO-TEX® yakhazikitsa chida chowunikira zachilengedwe

Chida cha Environmental Impact Assessment Tool tsopano chikupezeka kufakitale iliyonse yopanga nsalu yomwe ikufunsira kapena kulandira chiphaso cha STeP ndi OEKO-TEX®, ndipo ikupezeka kwaulere patsamba la SteP papulatifomu ya myOEKO-TEX®, ndipo mafakitale atha kutenga nawo gawo modzifunira.

Kuti akwaniritse cholinga chamakampani opanga nsalu chochepetsa mpweya wowonjezera kutentha ndi 30% pofika chaka cha 2030, OEKO-TEX® yapanga chida chosavuta, chosavuta kugwiritsa ntchito cha digito chowerengera mapazi a mpweya ndi madzi - Chida Chowunikira Chidziwitso cha Environmental Impact, chomwe Carbon ndi mapazi amadzi amatha. kuyezedwa panjira iliyonse, njira yonse komanso pa kilogalamu ya zinthu/zanthu. Pakadali pano, STeP yolembedwa ndi OEKO-TEX® Factory Certification ikuphatikizidwa mu chida, chomwe chimathandiza mafakitale:

• Kudziwa kuchuluka kwa carbon ndi madzi kukhudzidwa ndi zipangizo zomwe zimagwiritsidwa ntchito kapena zopangidwa ndi njira zopangira zomwe zikukhudzidwa;

• Kuchitapo kanthu pofuna kukonza ntchito ndi kukwaniritsa zolinga zochepetsera mpweya;

• Gawani deta ya carbon ndi madzi ndi makasitomala, osunga ndalama, ochita nawo bizinesi ndi ena omwe akukhudzidwa nawo.

• OEKO-TEX® yagwirizana ndi Quantis, katswiri wotsogolera sayansi wokhazikika, kuti asankhe njira ya Screening Life Cycle Assessment (LCA) kuti apange chida chowunikira chilengedwe chomwe chimathandiza mafakitale kuwerengera mphamvu zawo za carbon ndi madzi pogwiritsa ntchito njira zowonekera komanso zitsanzo za deta.

Chida cha EIA chimagwiritsa ntchito miyezo yovomerezeka padziko lonse lapansi:

Mpweya wa carbon umawerengeredwa potengera njira ya IPCC 2013 yomwe ikulimbikitsidwa ndi Greenhouse Gas (GHG) Protocol mphamvu ya madzi imayezedwa potengera njira ya AWARE yomwe bungwe la European Commission Material limalimbikitsa kutengera ISO 14040 Product LCA ndi Product Environmental Footprint PEF Evaluate.

Njira yowerengetsera chida ichi imachokera ku nkhokwe zodziwika padziko lonse lapansi:

WALDB - Environmental Data for Fiber Production and Textile Processing Steps Ecoinvent - Deta pa Global/Regional/International Level: Magetsi, Mpweya, Packaging, Zinyalala, Chemicals, Transport Zomera zikalowetsa deta yawo mu chida, chidachi chimapereka chidziwitso chonse kwa njira zopangira munthu payekha ndikuchulukitsidwa ndi data yoyenera mu nkhokwe ya Ecoinvent 3.5 ndi WALDB.
