Since its commissioning in December 2009, the "Central Asia–China" gas pipeline has supplied more than 500 bn cubic meters of natural gas to China, supporting energy needs in 27 provincial regions, including Hong Kong.
The pipeline’s main entry point into China, the "Khorgos" gas compressor station, has been operational for over 5,000 days since its launch. Managed by the West Pipeline Company, a Chinese gas infrastructure operator, the station handles up to 160 million cubic meters of gas daily. It has facilitated the transport of the entire 500 billion cubic meters of natural gas since operations began.
The gas pipeline stretches 1,833 kilometers, traversing central Uzbekistan, southern Kazakhstan, and the Chinese border at Khorgos. The journey from Central Asia to China takes approximately 84 hours, with the pipeline capable of transporting up to 60bn cubic meters of gas annually.
The natural gas supplied through the pipeline has replaced the use of an equivalent of 696 mn tons of coal, leading to substantial environmental benefits. Since 2009, the shift has resulted in:
- 731 mn tons of reduced carbon dioxide emissions.
- 25 mn tons of reduced sulfur dioxide emissions.
- 379 mn tons of reduced particulate matter.
- 6.27 mn tons of reduced nitrogen oxide emissions.
These reductions demonstrate the pipeline’s significant contribution to mitigating air pollution and supporting global sustainability goals.
