Dzidzo Inoburitsa Maitiro Ekudzikisa Carbon Footprint YeDzimba

Université Libre de Bruxelles (ULB) uye Corvinus University yeBudapest

A house's kabhoni tsoka inodzikira kupfuura 1kg mucarbon dioxide yakaenzana kune yega yega euro (inenge £ 0.80p) inoiswa mariri zvinhu zvekuvaka zvinogara zviripo, inowana tsvakiridzo nyowani kubva kuUniversité Libre de Bruxelles (ULB) uye Corvinus University yeBudapest. Chikuru kuchinja inobva ku investing in kutsigira mahwindo nemadziro ekunze.

Kubudirira kwezvinhu zvekuvaka kwakaverengerwa maererano nekuderedzwa kwekabhoni dhaidhirondi yakaenzana (CO₂eq) emissions pa euro yakaiswa mari. Izvi zvinomisa kukanganisa kwezvinobuda, semuenzaniso, methane ine 28 nguva yekudziya kwe CO₂ saka 1kg methane yakaenzana ne28kg CO₂eq.

Vatsvakurudzi vakaona kuti yakawanda CO₂eq emissions inobva mukushandiswa kweimba (nzvimbo yekushanda), kwete. kuvaka kana kugadzirisa, iine 65% yekabhoni yakazara yeimba inoenderana nesimba rinoshandiswa mukati mehupenyu hwayo.

Kana zvese zvinodhura zvichitariswa (kuvaka, kushanda, kugadzirisa), iyo yakazara mutengo wevaridzi ve "yakanyanya kusimba" dzimba ndeye 7-11% yakakwirira kupfuura yakajairwa dzimba. Mari yekuchengeta zvakare 20% (yakavharirwa) uye 13% (semi-detached) yakakwira mudzimba dzakasimba, nekuda kwekudzokororwa kunoitwa inogoneka zvinhu.

"Kukanganisa kwechikamu chekuvaka kunoenderana nenyika, saka kuenzanisa kwepasirese kunofanirwa kuitwa nekuchenjerera (semuenzaniso, maitiro ekushanda anoenderana nekudziya masisitimu, ayo anosiyana zvakanyanya pakati pematunhu). Zvakangodaro, kumwe kucherechedzwa kunogona kuitwa nyore nyore kune yakafara EU mamiriro, senge kuderera kwese kukanganiswa kwemafuremu emapuranga zvichienzaniswa nekongiri zvimiro kana kusaenzana pakati pezvakaiswa uye. kushanda carbon zvinokanganisa. Sezvo nzira nedata riripo, vaverengi vanofarira vanozokwanisa kuchinjisa zvatinenge tawana zviri nyore kuti zvienderane nezviri munharaunda,” vanodaro vaongorori.

Chidzidzo ichi zvakare chinoratidza kuti zvimwe zvikamu zveimba zvine simba rakakura pane kabhoni tsoka. Semuyenzaniso, zvinhu zvakagadzika zvaishandiswa kumadziro ekunze nemahwindo zvakakanganisa zvakanyanya, zvichideredza kuburitswa ne6kg uye 3-6kg paeuro zvichiteerana.

Sezvo chikamu chekugara chinotora 17% yezvose kabhoni pasi rose, chikamu ichi chinofanirwa kuve chinotariswa kune avo vane tarisiro yekudzikisa nharaunda kabhoni, uye tsvakiridzo iyi inoratidza uko kushandiswa kwezvinhu zvinogoneka kunogona kuiswa pamberi kune zvakanyanya kukanganisa.

Izvi zvakawanikwa zvakatanga kuburitswa mu Journal of Cleaner Production.
