This remarkable growth has led to a big cut in carbon dioxide emissions as well as toxic and harmful substances such as sulfur dioxide, nitrogen oxides and particulate matter.State Grid Tianjin Electric Power Co, a subsidiary of the national electricity provider State Grid, estimates that the reduction is the equivalent of the amount of CO2 absorbed by 767 million trees for a whole year.

The national green electricity trading market facilitates transactions for both physical green electricity and related green electricity certificates so that large-scale users, such as manufacturers and data centres, can buy their energy and ensure that it comes from a renewable source.
