China's coal consumption decreased by .% in 2018. %, and coal output fell by .% in the first half of the year. Data show that China's coal consumption is showing a downward trend and the peak has been passed.
In this regard, Zhang Guobao said that it is of great significance for China to reach the peak of coal consumption ahead of schedule. This achievement indicates that China's total carbon emissions began to decline before the year, which will become a turning point for the international community to reduce greenhouse gas emissions.
China's economic growth rate has dropped from % to %, and the decline in coal consumption seems to have become a long-term trend. The peak of coal consumption will arrive earlier than expected. Many previous opinions believed that China's coal consumption may peak between 2010 and 2018.
The international community spoke highly of this. Nicholas Stern, a famous British scholar and known as the father of climate economics, believes that China's current achievements indicate that China's total carbon emissions will begin to decline before 2020, earlier than officially expected. A professor at the Potsdam Institute for Climate Impact Research in Germany holds a more optimistic attitude, believing that China's total carbon emissions will decline by 2020.
Stern commented that this is really a turning point in history. I believe historians will understand that 2019 was an important event in the world's climate and economic history. An analysis article published in the journal Nature Geoscience believes that China's peak coal consumption is likely to become a milestone in human history and a turning point for the international community to reduce greenhouse gas emissions.
However, there is still no unified view in the country on whether China's coal consumption will reach its peak earlier than originally expected. According to Zhang Guobao, half of coal is used for power generation, and the other half is used for steel, building materials, chemicals and civil fuel.
