二氧化碳截住同儲埋(簡寫做碳截儲CCS)即係捉實啲大型發電廠產生嘅二氧化碳(CO2),然後用各種辦法儲起佢,唔畀佢出大氣層。碳截儲係調慢全球變暖嘅一個方法,商業用大型二氧化碳截住嘅方法已經用咗一段時間,好成熟。將二氧化碳渚入地層係做過吓,不過,要長期咁儲埋二氧化碳只係一個未實踐嘅諗頭。到而家(2007年)為止,未有一間投產嘅電廠安裝咗碳截儲嘅設施。

有碳截儲設施嘅電廠,比起冇嘅廠,排少八到九成嘅二氧化碳[1],而有減排設施嘅電廠運行嗰時,大約用多兩到九成嘅能源[1],呢個只限於新起、近住儲埋地點嘅廠,如果現成嘅電廠加減排設施會重貴。

一係將啲二氧化碳㘉入地下岩層,深海。或者變成碳酸礦物。深海儲埋會搞到海洋酸化。儲埋喺地下岩層而家係最理想同可行嘅方法,現有嘅地點估計可以至少儲 2000 Gt 嘅 CO2(而家人類每年整 30 Gt 嘅 CO2 出嚟[2])。
