In order to ensure the demand for warm and clean winter in the north, in the past less than a month, PetroChina has successively put into operation six geothermal clean heating projects in Xiong'an new area, Tangshan, Dezhou and other places, with a new heating area of more than 9 million square meters, which is 1.6 times the cumulative heating area completed by the end of 2020.

    So far, PetroChina has increased the number of clean heating projects in operation and under construction to 16. The projects in operation have achieved an annual replacement of 350000 tons of standard coal, an annual emission reduction of nearly 1 million tons of carbon dioxide and an annual equivalent of 260 million cubic meters of natural gas.
