It was a moment for the Chinese people to savor. For nearly two years, they had called on Beijing to take action on its air pollution crisis. Websites exploded with pictures and data, documenting the terrifying health and economic costs of the pollution: a drop in life expectancy of 5.5 years in the country’s heavily polluted north and an estimated $112 billion in labor and health care costs in 2005. Experts and citizens shared information, expressed views in polls, and demanded change. Finally, in September 2013, faced with mounting social discontent, Premier Li Keqiang announced a sweeping new plan to try to address the country’s air quality problems.
