cov 28th Lub Rooj Sab Laj ntawm Pawg Neeg (COP28) mus rau UN Framework Convention ntawm nyab xeeb kev hloov (UNFCCC), nrov npe hu ua United Nations nyab xeeb kev hloov Conference, tam sim no muaj nyob rau hauv UAE tau tshaj tawm ntau lub tswv yim thiab kev sib koom tes tsom rau sustainable Kev loj hlob hauv nroog uas suav nrog kev tshaj tawm 'Lub Tsev Txhaum Cai' thiab 'Cement thiab pob zeb tawg'
Cov Txheej Txheem Tshaj Tawm tau pib ntawm COP26 los kaw qhov sib txawv ntawm kev sib koom tes. Nws lub hom phiaj los txhawb kev sib koom tes thoob ntiaj teb thiab txhawb kev nqis tes ua kev nyab xeeb hloov kom ua tau raws li Paris Agreement lub hom phiaj decarbonisation. Nws muab lub hauv paus kev sib koom tes rau cov zej zog thoob ntiaj teb. "Lub Tsev Kev Txhaum Cai" thiab "Cov Cement thiab Kev Ua Txhaum Cai" yog ib feem ntawm Cov Txheej Txheem Ua Haujlwm.
Lub tuam tsev lag luam tsis ua tau zoo rau lub hom phiaj ntawm net-zero emissions los ntawm 2050. Emissions los ntawm cov sector no yog loj hlob li ntawm 1% ib xyoos txij li thaum 2015. Nyob rau hauv 2021, lub zog noj thiab carbon emissions ntawm lub tsev thiab kev tsim kho sector yog 34. % ntawm lub zog xav tau thiab 37% ntawm carbon emissions. Operational Energy related CO2 Cov emissions ntawm cov sector no tau nce 5% tshaj 2020. Qhov sector no sawv cev rau 40% ntawm cov teb chaws Europe xav tau lub zog, ib nrab ntawm cov fossil fuels. Obviously, txo qis carbon emissions yog ib qho tseem ceeb rau cov sector no kom ua tiav lub hom phiaj ntawm net-zero los ntawm nruab nrab ntawm lub xyoo pua no. Txog rau qhov no, kev ua haujlwm emissions yuav tsum txo qis li 50% los ntawm 2022 qib los ntawm 2030 kom tau txais cov khoom nyob rau hauv kev khiav mus rau net-zero emissions los ntawm 2050. Cov kev sib koom tes thoob ntiaj teb tau pib ua haujlwm hauv keeb kwm yav dhau los tshem tawm cov fwj thiab txhawb kev ua huab cua. Ib yam li ntawd, nrog rau tag nrho cov emissions nce txij li xyoo 2015, cov cement thiab pob zeb ua haujlwm tseem tsis nyob rau hauv txoj kev kom ua tau raws li qhov tsis muaj emissions los ntawm 2050.
Lub koom haum thoob ntiaj teb kev sib koom tes, Cov Tsev Sib Tw tau pib los ntawm Fabkis thiab Morocco nrog UN Environment Program (UNEP) ntawm COP28 ntawm 6.th Lub Kaum Ob Hlis 2023 los hloov lub tsev lag luam (uas suav txog 21% ntawm lub ntiaj teb cov pa roj carbon monoxide emissions) mus rau lub hom phiaj ntawm zero emissions thiab climate resilient vaj tse los ntawm 2030. -Teem txwv lossis tso cai rau tib neeg hloov pauv cov xwm txheej sab nraum zoov Qhov no suav nrog lub peev xwm ntawm lub tsev kom tsis txhob muaj cua sov dhau los ntawm kev tsim qauv xws li kev siv shading, ntuj breezes, thiab lwm yam. Resilience nyob rau hauv lub tsev yog hais txog lub peev xwm ntawm ib lub tsev kom tau raws li cov neeg xav tau kev pab thiab muab kev nyab xeeb, ruaj khov thiab xis siv nyob rau hauv teb rau cov kev hloov nyob rau hauv lub teb chaws Nees nkaum yim lub teb chaws tau cog lus rau lawv cov kev cog lus mus rau qhov kev pib ua kom deb li deb tau qhib kev caw mus rau cov teb chaws tuaj koom nrog Kev Sib Tw Hauv Tsev).
COP28 kuj tau pom qhov kev tshaj tawm ntawm Cement thiab pob zeb tawg los ntawm Canada thiab UAE. Qhov no yuav ua haujlwm los ua kom cov cement huv si yog qhov kev xaiv zoo tshaj plaws thiab tsim kom muaj zero emissions nyob rau hauv cov cement ntau lawm los ntawm 2030. Lub tebchaws United Kingdom, Ireland, Nyiv thiab lub teb chaws Yelemees tau pom zoo rau pob zeb tawg kom deb li deb.
Nws tseem ntxov dhau los tawm tswv yim rau "Cov Tsev Sib Tw" thiab "Cement thiab pob zeb tawg". Txawm li cas los xij, muab cov theem tam sim no ntawm cov pa roj carbon emissions thiab tus nqi nce hauv emissions, tso tawm ntawm ob txoj kev pib Breakthrough yog cov kauj ruam mus rau qhov raug. Tsis muaj ntau lub tebchaws tau cog lus rau lawv cov lus cog tseg. Kev txhawb nqa los ntawm cov teb chaws xws li Tuam Tshoj thiab Is Nrias teb yuav mus ntev tab sis lawv cov phiaj xwm kev lag luam yuav txwv tsis pub lawv koom nrog cov phiaj xwm no.
