从国家管网集团获悉，西气东输管道系统（包含西气东输一、二、三线）累计向长三角地区输送天然气突破5000亿立方米。

目前，西气东输管道途经长三角地区30个地市，供气量约占长三角地区天然气消费总量的四分之三，超2亿人口从中受益，为推动长三角一体化高质量发展持续注入“绿色动能”。

据介绍，西气东输管道系统累计向长三角地区输送天然气突破5000亿立方米，折合替代标煤6.45亿吨，可减少排放二氧化硫1272万吨、粉尘3.62亿吨、二氧化碳7.31亿吨，相当于种植阔叶林22亿公顷。

近年来，国家管网集团加速推进管网互联互通，推动西气东输管道系统在长三角地区与中俄东线、苏皖管道等互联互通，织“线”成“网”，形成了“西气东输、俄气南下、南气北上、川气东送、海气登陆、灵活调配、全面保障”的供气格局。长三角地区天然气管网在“全国一张网”中的能源供应核心枢纽作用进一步凸显。

截至2023年底，国家管网集团管理运营全国主干油气管网达10.43万公里，其中长三角地区的在役油气管道里程达1.2万公里。

It was learned from the National Pipeline Network Group that the West-East gas transmission pipeline system (including West-East gas transmission one, two, and three lines) has delivered more than 500 billion cubic meters of natural gas to the Yangtze River Delta.

At present, the West-East natural gas pipeline passes through 30 cities in the Yangtze River Delta region, supplying about three-quarters of the total natural gas consumption in the Yangtze River Delta region, benefiting more than 200 million people and injecting "green energy" into the integrated high-quality development of the Yangtze River Delta.

According to reports, the west-east gas pipeline system to the Yangtze River Delta region to transport more than 500 billion cubic meters of natural gas, equivalent to replacing 645 million tons of standard coal, can reduce the emission of sulfur dioxide 12.72 million tons, dust 362 million tons, carbon dioxide 731 million tons, equivalent to planting broad-leaf forest 2.2 billion hectares.

In recent years, the National Pipeline Network Group has accelerated the interconnection of the pipeline network, promoted the interconnection of the west-east gas transmission pipeline system with the China-Russia East Route and the Suzhou-Anhui Pipeline in the Yangtze River Delta region, woven "lines" into "networks", and formed a gas supply pattern of "West-east gas transmission, Russian gas southbound, south gas northbound, Sichuan gas eastbound, sea gas landing, flexible deployment, and comprehensive guarantee". The role of the Yangtze River Delta natural gas pipeline network as the core hub of energy supply in the "national one network" has been further highlighted.

By the end of 2023, the National Pipeline Network Group has managed and operated 104,300 kilometers of main oil and gas pipeline networks across the country, including 12,000 kilometers of oil and gas pipelines in service in the Yangtze River Delta region.
