Ucwaningo Lwembula Indlela Yokunciphisa I-Carbon Footprint Yezindlu

I-Université Libre de Bruxelles (ULB) kanye neYunivesithi yaseCorvinus yaseBudapest

Owendlu umngcele wekhabhoni yehla ngaphezu kwe-1kg ku-carbon dioxide okulingana ne-euro ngayinye (cishe u-£0.80p) etshalwe kuyo izinto zokwakha ezisimeme, ithola ucwaningo olusha oluvela ku-Université Libre de Bruxelles (ULB) kanye ne-Corvinus University yase-Budapest. Okukhulu kunayo yonke umthelela ivela ekutshaleni imali esimeme amafasitela nezindonga zangaphandle.

UBruno van Pottelsberghe, uRector we-Corvinus University of Budapest, kanye no-Joran Douhard, ikhandidethi ye-PhD e-Solvay Brussels School of Economics and Management of ULB, baqhathanisa izindlu ezijwayelekile (ezihlukanisiwe nezihlukene phakathi) nezinguqulo ezisimeme ezakhiwe ngezinto ezithinta imvelo.

Ukusebenza kwempahla yokwakha kubalwe ngokwemibandela yokukhishwa kwekhabhoni dioxide encishisiwe (CO₂eq) nge-euro etshaliwe. Lokhu kulinganisa umthelela wezinto ezikhishwayo, isb, i-methane inamandla aphindwe izikhathi ezingu-28 kokufudumala kwe-CO₂ ngakho i-1kg methane ilingana no-28kg CO₂eq.

Abacwaningi bathola ukuthi ukukhishwa okuningi kwe-CO₂eq kuvela ekusetshenzisweni kwendlu (isiteji sokusebenza), kunokuba ukwakhiwa noma ukunakekelwa, okuno-65% wengqikithi yekhabhoni yendlu ngenxa yamandla asetshenziswe ngesikhathi sokuphila kwayo.

Lapho zonke izindleko zicatshangelwa (ukwakha, ukusebenza, ukugcinwa), izindleko eziphelele zobunikazi bezindlu "ezisimeme" ziphakeme ngo-7-11% kunezindlu ezijwayelekile. Izindleko zokunakekela izindlu nazo zingu-20% (zihlukanisiwe) kanye no-13% (ezihlukene kancane) eziphakeme ezindlini ezisimeme, ngenxa yokushintshwa kwezindlu njalo njalo. izinto ezisimeme.

“Umthelela womkhakha wezokwakha uncike ezweni, ngakho-ke ukuqhathaniswa kwamazwe ngamazwe kufanele kwenziwe ngokuqapha (isb, umthelela wokusebenza uncike kakhulu ezinhlelweni zokufudumeza, ezihluka kakhulu phakathi kwezifunda). Noma kunjalo, okunye ukuqaphela kungenziwa kube lula kungqikithi ye-EU ebanzi, njengomthelela ophansi wonkana wohlaka lwamapulangwe uma kuqhathaniswa nezakhiwo zikakhonkolo noma ukungalingani phakathi kokuhlanganisiwe ikhabhoni yokusebenza imithelela. Njengoba indlela yokusebenza nedatha ikhona, abafundi abanentshisekelo bazokwazi ukulungisa kalula imiphumela yethu ukuze ihambisane nemininingwane yendawo,” kusho abacwaningi.

Ucwaningo luphinde lubonise ukuthi izingxenye ezithile zendlu zinethonya elikhulu ku-carbon footprint. Isibonelo, izinto ezizinzile ezisetshenziselwa izindonga namafasitela zangaphandle zibe nomthelela omkhulu kakhulu, zehlisa ukukhishwa kwekhabhoni ngo-6kg no-3-6kg nge-euro ngayinye ngokulandelana.

Njengoba imboni yezindawo zokuhlala ibalelwa ku-17% wabo bonke ukuphuma kwekhabhoni emhlabeni jikelele, lo mkhakha kufanele ube yindawo okugxilwe kuyo labo abanethemba lokunciphisa izinga lekhabhoni emphakathini, futhi lolu cwaningo lukhomba lapho ukusetshenziswa kwezinto ezisimeme kungase kubekwe eqhulwini ukuze kube nomthelela omkhulu kakhulu.

Lokhu okutholakele kwashicilelwa okokuqala kuJournal of Cleaner Production.
