Beijing’s air pollution was so bad last December that hundreds of flights were canceled at the city’s international airport due to poor visibility.

While China made improvements to air quality in 2014 with its “war on pollution,” smog is on the rise again because of increased industrial production in China’s steelmaking heartland south of Beijing, according to Greenpeace. Shifting wind patterns have blown air pollution north, with heavy smog settling into the Jingjinji national capital region (Beijing-Tianjin-Hebei).

China also recently announced that its domestic railway will expand by nearly 19,000 miles (30,000 kilometers) before 2020, with one-third of the increased mileage to be high-speed rail. According to China’s Economic Daily newspaper, “by 2020, China will have built a comprehensive modern transportation system that is safe, convenient, efficient and green.”
