Marka loo eego Qiimaynta Wareegga Nolosha ee cusub (LCA) ee baakadaha birta ah oo ay ku jiraan xidhitaanka birta, aerosols birta, khadka guud ee birta, gasacadaha cabitaanka aluminium, aluminium iyo gasacadaha cuntada ee birta, iyo baakadaha khaaska ah, kaas oo ay dhamaystirtay ururka Baakadaha Birta Yurub. Qiimaynta waxay ku lug leedahay wareegga nolosha ee baakadaha birta ah ee laga soo saaro Yurub iyada oo lagu saleynayo xogta wax soo saarka ee 2018, asal ahaan iyada oo loo marayo habka oo dhan laga bilaabo soo saarista alaabta ceeriin, wax soo saarka alaabta, ilaa dhamaadka-nololeed.
Qiimaynta cusubi waxay daaha ka qaadaysaa in warshadaha baakadaha birta ay si wayn hoos ugu dhaceen gaaska aqalka dhirta lagu koriyo marka la barbar dhigo qiimayntii hore ee meertada nolosha, waxa kale oo ay xaqiijisay in ay ka go'an tahay in la dhimo qiiqa kaarboonka iyo in la kala saaro wax soo saarka raadkeeda kaarboonka. Waxaa jira afar arrimood oo muhiim ah oo sababi kara dhimista sida soo socota:
1. Dhimista miisaanka qasaca, tusaale 1% gasacadaha cuntada ee birta ah, iyo 2% gasacadaha cabitaanka aluminium;
2. Heerarka dib-u-warshadaynta waxay kor u kacday baakadaha aluminium iyo birta labadaba, tusaale ahaan 76% cabitaanka, 84% baakadaha birta;
3. Hagaajinta wax soo saarka alaabta ceeriin waqti ka dib;
4. Hagaajinta hababka wax soo saarka gasacadaha, iyo sidoo kale tamarta iyo waxtarka kheyraadka.
Dhinaca isbeddelka cimilada, daraasaddu waxay tilmaantay in gasacadaha cabbitaannada aluminiumku ay saamayn ku yeesheen isbeddelka cimilada ay hoos u dhacday qiyaastii 50% muddadii u dhaxaysay 2006 ilaa 2018.
Tusaale ahaan u soo qaado baakadaha birta ah, daraasaddu waxay muujinaysaa in saamaynta isbeddelka cimilada muddada u dhaxaysa 2000 ilaa 2018 la dhimay:
1. In ka yar 20% aerosol-ka (2006 - 2018);
2. In ka badan 10% baakadaha gaarka ah;
3. In ka badan 40% xiritaanka;
4. In ka badan 30% ee gasacadaha cuntada iyo baakadaha khadka guud.
Marka laga soo tago guulaha xusidda mudan ee kor ku xusan, 8% dheeraad ah oo hoos u dhac ku yimid gaaska aqalka dhirta lagu koriyo ayaa waxaa gaaray warshadaha tinplate ee Yurub intii u dhaxeysay 2013 ilaa 2019.
