Against all odds : how America's century-old quest for clean air may spur a new era of global environmental cooperation

Healthy air quality is a growing global concern. Robert Percival discusses the critical junctures in U.S. environmental history that have led to global environmental regulation, particularly in relation to China.

According to the World Health Organization in 2013, more than one million people die every year in China from exposure to air pollution.

Referencing historical U.S. air quality achievements, particularly the Clean Air Act, Percival points toward a turning point in China's legislation and attitude towards this environmental issue.
