Ọmụmụ na-ekpughe otu esi ebelata akara ukwu carbon nke ụlọ

Mahadum Libre de Bruxelles (ULB) na Mahadum Corvinus nke Budapest

Otu ụlọ akara ụkwụ carbon na-ebelata ihe karịrị 1kg na carbon dioxide dabara maka euro ọ bụla (ihe dị ka £ 0.80p) etinyere na ya. ihe ụlọ na-adigide, chọtara nyocha ọhụrụ sitere na Université Libre de Bruxelles (ULB) na Mahadum Corvinus nke Budapest. Nke kasịnụ mmetụta na-abịa site na itinye ego adigide windo na mgbidi dị n'èzí.

Bruno van Pottelsberghe, Rector nke Corvinus University of Budapest, na Joran Douhard, onye nyocha PhD na Solvay Brussels School of Economics and Management of ULB, jiri ụlọ ọkọlọtọ tụnyere ụlọ (nke a na-ekewapụ na nke nwere ọkara) na nsụgharị na-adigide nke ejiri ihe ndị ọzọ na-emekọrịta ihe na gburugburu ebe obibi.

A gbakọrọ ịdị irè nke ihe owuwu ụlọ n'usoro nke mbelata carbon dioxide dakọtara (CO₂eq) ikuku kwa euro etinyere. Nke a na-akọwapụta mmetụta nke ikuku ikuku, dịka, methane nwere ike ikpo ọkụ nke CO₂ ugboro 28, ya mere 1kg methane ruru 28kg CO₂eq.

Ndị nchọpụta ahụ chọpụtara na ọtụtụ ihe ọkụkụ CO₂eq na-abịa site n'iji ụlọ (ogbo arụ ọrụ), kama ịbụ. -ewu ma ọ bụ nrụzi, yana 65% nke mkpokọta carbon akara ụkwụ sitere na ike ejiri n'oge ndụ ya.

Mgbe a na-atụle ụgwọ niile (mwube, ịrụ ọrụ, mmezi), ọnụ ọgụgụ zuru ezu nke ụlọ nke ụlọ "na-adigide" bụ 7-11% dị elu karịa ụlọ ndị ọkọlọtọ. Ọnụ ego nlekọta ahụ dịkwa 20% (kewapụrụ) yana 13% (nkewa nke ọkara) dị elu n'ụlọ ndị na-adigide, n'ihi na a na-edochi ya ugboro ugboro. ihe na -adigide.

"Mmetụta nke ngalaba ihe owuwu na-adabere na obodo, ya mere ekwesịrị iji nlezianya mee ntụnyere mba ụwa (dịka ọmụmaatụ, mmetụta ọrụ na-adabere na usoro ikpo ọkụ, nke dịgasị iche iche n'etiti mpaghara). Ka o sina dị, ụfọdụ nleba anya nwere ike ịchịkọta ọnụ n'ụzọ zuru oke na mpaghara EU, dị ka mmetụta dị ala n'ozuzu nke osisi osisi ma e jiri ya tụnyere ihe arụrụ arụ ma ọ bụ enweghị aha n'etiti ihe mejupụtara ya na carbon arụ ọrụ mmetụta. Dị ka usoro na data dị, ndị na-agụ akwụkwọ nwere mmasị ga-enwe ike ịmegharị nsonaazụ anyị n'ụzọ dị mfe na nkọwa mpaghara," ndị nchọpụta ahụ kwuru.

Ọmụmụ ihe ahụ gosikwara na akụkụ ụfọdụ nke ụlọ na-enwe mmetụta ka ukwuu n'ụkwụ carbon. Dịka ọmụmaatụ, ihe na-adịgide adịgide a na-eji maka mgbidi na windo dị n'èzí nwere mmetụta kachasị ukwuu, na-ebelata ihe ọkụkụ site na 6kg na 3-6kg kwa euro n'otu n'otu.

Dị ka ngalaba obibi bụ 17% nke ihe niile akuku carbon n'ụwa niile, ngalaba a kwesịrị ịbụ ebe a na-elekwasị anya maka ndị na-atụ anya ibelata akara ukwu carbon nke ọha mmadụ, nchọpụta a na-egosikwa ebe a ga-ebute iji ihe ndị na-adịgide adịgide ebute ụzọ maka mmetụta kachasị.
