In 2011, the world's highest natural gas station in Lhasa City of southwest China's Xizang Autonomous Region was put into operation. For the 13 years, it has supplied 475 million cubic meters of gas and reduced carbon dioxide emissions by 1,030,700 tons. This is a microcosm of Xizang's active participation in global carbon emission reduction and green transformation over the years. (Photo/Chinanews.com)
