Lub ntiaj teb no yuav zoo li txawv heev yog tsis muaj hlau. Tsis muaj txoj kev tsheb ciav hlau, choj, tsheb kauj vab lossis tsheb. Tsis muaj tshuab ntxhua khaub ncaws lossis lub tub yees.

Feem ntau cov khoom siv kho mob thiab cov cuab yeej siv tshuab uas siab heev yuav luag tsis muaj peev xwm tsim tau. Hlau yog qhov tseem ceeb rau kev lag luam ncig, tab sis qee tus neeg tsim cai thiab cov koom haum tsis yog tsoomfwv tseem pom nws ua teeb meem, thiab tsis yog kev daws teeb meem.

Lub Koom Haum European Steel Association (EUROFER), uas sawv cev rau yuav luag txhua qhov kev lag luam hlau hauv Tebchaws Europe, tau cog lus tias yuav hloov qhov no, thiab tab tom hu kom EU txhawb nqa 60 qhov project loj uas tsis muaj carbon ntau thoob plaws lub tebchaws los ntawm xyoo 2030.

"Cia peb rov qab mus rau qhov yooj yim: hlau yog ib puag ncig, 100 feem pua ​​​​​​rov siv dua, tsis muaj qhov kawg. Nws yog cov khoom siv rov ua dua tshiab tshaj plaws hauv ntiaj teb nrog 950 lab tonnes ntawm CO2 txuag txhua xyoo. Hauv EU peb muaj kwv yees li ntawm 88 feem pua, "Axel Eggert, EUROFER tus thawj coj dav dav hais.

Cov khoom siv hlau tshiab kawg yeej ib txwm tsim kho tas li. "Muaj ntau tshaj 3,500 hom hlau, thiab ntau tshaj 75 feem pua ​​- sib dua, ua haujlwm zoo dua thiab ntsuab dua - tau tsim kho hauv 20 xyoo dhau los. Qhov no txhais tau tias yog tias lub Eiffel Tower raug tsim niaj hnub no, peb tsuas xav tau ob feem peb ntawm cov hlau siv thaum lub sijhawm ntawd," Eggert hais.

Cov phiaj xwm uas tau npaj tseg yuav txo cov pa roj carbon ntau dua 80 lab tonnes hauv yim xyoo tom ntej. Qhov no sib npaug rau ntau dua ib feem peb ntawm cov pa roj carbon niaj hnub no thiab yog 55 feem pua ​​​​​​txiav piv rau xyoo 1990. Kev tsis muaj pa roj carbon tau npaj tseg los ntawm xyoo 2050.
