Uphononongo luDiza indlela yokuNcitshiswa kweCarbon Footprint yeZindlu

Université Libre de Bruxelles (ULB) kunye neYunivesithi yaseCorvinus yaseBudapest

Yendlu Imibhalo yenyawo yekhabhoni yehla ngaphezu kwe-1kg kwi-carbon dioxide elingana nayo yonke i-euro (malunga ne-£0.80p) etyalwe kuyo izinto zokwakha ezizinzileyo, ufumana uphando olutsha kwi-Université Libre de Bruxelles (ULB) kunye neYunivesithi yaseCorvinus yaseBudapest. Eyona inkulu mpe mbelelo ivela kutyalo-mali kwi ezizinzileyo iifestile kunye neendonga zangaphandle.

UBruno van Pottelsberghe, uMlawuli weYunivesithi yaseCorvinus yaseBudapest, kunye noJoran Douhard, umviwa we-PhD kwiSikolo soQoqosho sase-Solvay Brussels kunye noLawulo lwe-ULB, bathelekisa izindlu ezisemgangathweni (ezicandiweyo kunye ne-semi-detached) kwiinguqulelo ezizinzileyo ezakhiwe ngezinto ezihambelana nokusingqongileyo.

Ukusebenza kwezinto zokwakha kubalwa ngokwemiqathango yokunciphisa i-carbon dioxide equivalent (CO₂eq) ekhutshwayo nge-euro etyalwe. Oku kubeka emgangathweni impembelelo yokukhutshwa kwezinto ezikhutshwayo, umz., imethane inamathuba angama-28 okufudumala kweCO₂ ngoko ke i-1kg yemethane ilingana ne-28kg CO₂eq.

Abaphandi bafumanise ukuba uninzi lokukhutshwa kweCO₂eq luvela kusetyenziso lwendlu (inqanaba lokusebenza), kunokuba ukwakhiwa okanye ugcino, kunye ne-65% yekhabhoni iyonke yendlu ebalelwa kumandla asetyenziswe ngexesha lokuphila kwayo.

Xa zonke iindleko zicatshangelwa (ukwakha, ukusebenza, ukugcinwa), iindleko ezipheleleyo zobunini bezindlu "ezizinzileyo" ziphezulu nge-7-11% kunezindlu eziqhelekileyo. Iindleko zogcino zikwangama-20% (acatshulwe) kwaye i-13% (eyohluliweyo) iphezulu kwizindlu ezizinzileyo, ngenxa yokutshintshwa rhoqo kwezindlu. izinto ezizinzileyo.

"Impembelelo yecandelo lokwakha ixhomekeke kwilizwe, ngoko ke uthelekiso lwamazwe ngamazwe kufuneka lwenziwe ngononophelo (umzekelo, impembelelo yokusebenza ixhomekeke kakhulu kwiinkqubo zokufudumeza, ezihluka kakhulu phakathi kwemimandla). Nangona kunjalo, olunye uqwalaselo lunokwenziwa ngokubanzi ngokubanzi kumxholo obanzi we-EU, njengempembelelo ephantsi iyonke yezakhelo zamaplanga xa kuthelekiswa nezakhiwo zekhonkrithi okanye ukungalingani phakathi kokuqulathwe ikhabhoni yokusebenza iimpembelelo. Njengoko indlela yokusebenza kunye neenkcukacha zikhoyo, abafundi abanomdla baya kukwazi ukuziqhelanisa ngokulula neziphumo zethu kwiinkalo zengingqi,” batsho abaphandi.

Uphononongo lukwabonisa ukuba amacandelo athile endlu anempembelelo enkulu kwi-carbon footprint. Ngokomzekelo, izinto ezizinzileyo ezisetyenziselwa iindonga zangaphandle kunye neefestile zinempembelelo enkulu, ukunciphisa ukukhutshwa kwe-6kg kunye ne-3-6kg nge-euro ngokulandelanayo.

Njengoko icandelo lokuhlala lithatha i-17% yabo bonke ukukhutshwa kwekhabhoni kwihlabathi jikelele, eli candelo kufuneka libe yindawo ekugxilwe kuyo abo banethemba lokunciphisa i-carbon footprint yoluntu, kwaye olu phando lubonisa apho ukusetyenziswa kwezinto ezizinzileyo kunokubekwa phambili kwimpembelelo enkulu.

Ezi ziphumo zapapashwa okokuqala kwiJenali yeMveliso yoCoca.
