據(jù)國(guó)家管網(wǎng)集團(tuán)介紹，自2004年正式投產(chǎn)以來(lái),西氣東輸工程輸氣量已累計(jì)輸送天然氣超7000億立方米。2021年，西氣東輸管道系統(tǒng)累計(jì)輸送天然氣首次突破1000億立方米。
The west-to-east gas pipeline has sent more than 700 billion cubic meters of natural gas to eastern China since it was officially put into operation in 2004. In 2021, the annual volume of natural gas transported by the pipeline has, for the first time, exceeded 100 billion cubic meters, according to PipeChina.
西氣東輸項(xiàng)目輸氣量折合替代標(biāo)煤9.32億噸，減少二氧化碳排放10.2億噸、粉塵5.08億噸，相當(dāng)于種植31.8億公頃闊葉林。
Over the past years, the project has reduced the use of approximately 932 million tonnes of standard coal and cut carbon dioxide emissions and dust by 1.02 billion tonnes and 508 million tonnes, respectively, which is equivalent to adding 3.18 billion hectares of broad-leaved forests.
