Air pollution has reached record levels as coal production in China has increased. In some areas, it was stated that the visibility decreased below 200 meters. Schools in the capital, Beijing, which will host the Winter Olympics in February, have been instructed to suspend physical education classes and outdoor activities. Highways to major cities such as Shanghai, Tianjin and Harbin were also closed to traffic due to poor visibility.
China, the world’s biggest polluter, has promised the UN to peak its emissions before 2030 and reduce them to zero by 2060.
