Raws li kev cai tswj hwm, cov tuam txhab roj teeb yuav tsum tau ua qhov kev ntsuas lub neej (LCA) los xam cov ntaub ntawv tag nrho cov saw carbon emission los ntawm cov khoom siv raw, kev tsim khoom mus rau kev thauj mus los, thiab ua tiav qhov thib peb - pov thawj ntawm tog. Cov ntaub ntawv cuam tshuam yuav raug suav nrog hauv "lub roj teeb passport" thiab txuas nrog cov ntaub ntawv sib koom ua ke ntawm European Union. Yav dhau los, qhov kev tshaj tawm cov pa roj carbon hneev taw tau pib thaum Lub Ob Hlis 2025, thiab 2027 txwv txoj cai yuav ua tiav qhov kev hloov kho tshiab los ntawm "kev tshaj tawm" mus rau "kev tswj hwm thiab kev tswj hwm".
Cov pa roj carbon hneev taw yuav hloov kho qhov kev sib tw toj roob hauv pes ntawm kev lag luam, thiab qis -carbon peev xwm yuav dhau los ua qhov kev sib tw tseem ceeb rau kev xa tawm. Raws li cov ntaub ntawv los ntawm European Union, kev siv tus nqi ntawm cov khoom siv rov ua dua rau cov roj teeb raws li xav tau kom ncav cuag 16% rau cobalt thiab 6% rau lithium los ntawm 2027, ntxiv rau kev hloov pauv ntawm cov saw hlau rau kev lag luam ncig.
