Isi yahinduka cyane iyo hatabaho ibyuma. Nta gari ya moshi, ibiraro, amagare cyangwa imodoka. Nta mashini zimesa cyangwa firigo.

Ibikoresho byinshi bigezweho byo kwa muganga n'ibikoresho bya mekanike ntibyaba bigoye kubikora. Icyuma ni ingenzi ku bukungu bw'uruziga, nyamara bamwe mu bashyiraho politiki n'imiryango itegamiye kuri leta bakomeje kubibona nk'ikibazo, atari igisubizo.

Ishyirahamwe ry’Uburayi ry’Ibyuma (EUROFER), rihagarariye hafi inganda zose z’ibyuma mu Burayi, ryiyemeje guhindura ibi, kandi rirasaba inkunga y’Umuryango w’Ubumwe bw’u Burayi kugira ngo imishinga 60 ikomeye igabanya karubone ishyirwe mu bikorwa ku mugabane wose bitarenze umwaka wa 2030.

“Reka dusubire ku by’ibanze: icyuma ni uruziga mu buryo busanzwe, gishobora kongera gukoreshwa 100 ku ijana, kidashira. Ni cyo gikoresho gishobora kongera gukoreshwa cyane ku isi, aho toni miliyoni 950 za CO2 zibikwa buri mwaka. Muri EU dufite igipimo cya 88 ku ijana cyo kongera gukoreshwa,” ibi ni ibyavuzwe na Axel Eggert, umuyobozi mukuru wa EUROFER.

Ibikoresho by'icyuma bigezweho bihora bitegurwa. Eggert agira ati: “Hari ubwoko bw'ibyuma birenga 3.500, kandi ibirenga 75% - byoroshye, bikora neza kandi bifite ibidukikije - byakozwe mu myaka 20 ishize. Ibi bivuze ko iyo Umunara wa Eiffel uba wubatswe uyu munsi, twari gukenera bibiri bya gatatu by'ibyuma byakoreshejwe icyo gihe.”

Imishinga yatanzwe izagabanya imyuka ihumanya ikirere irenga toni miliyoni 80 mu myaka umunani iri imbere. Ibi bingana na kimwe cya gatatu cy'imyuka ihumanya ikirere ikoreshwa muri iki gihe kandi ni ukugabanukaho 55% ugereranije n'urugero rwo mu 1990. Kutagira umwuka uhumanya ikirere biteganijwe mu 2050.
