Globalization's Blowback

A recent study of air pollution in the western United States made a startling finding: despite a 50 percent drop over the past 25 years in US emissions of smog-producing chemicals like nitrogen oxides (NOx), smog actually increased during that period in the rural US West – even in such ‘pristine’ environments as Yellowstone National Park. Most of this increase was traced to “the influx of pollution from Asian countries, including China, North and South Korea, Japan, India, and other South Asian countries.”[1] That’s because over the same period that NOx emissions declined in the US, they tripled in Asia as a whole.[2] In media reports of the study, China and India are described as the “worst offenders” of this fugitive “Asian pollution”.[3]

Left only with these findings, a reasonable conclusion would be that the US has become more environmentally enlightened in recent decades, while Asia – particularly ‘developing’ Asia – is a veritable eco-reprobate, sacrificing not only its own but global airsheds to choking pollution. The new, anti-environmental EPA director, Scott Pruitt, recently expressed this view in explaining why the US should exit the Paris Climate Accord: “[China and India] are polluting far more than we are.”[4]

What’s missing?

A similar study of global air pollution drift in 2014, focusing on China and the US, made comparable findings, but included an important factor missing from the more recent study: production for export. Among other things, the scholars of the older study asked how much of the Chinese air pollution drifting to the Western US was occasioned specifically in the production of exports for world markets (including the top destination for Chinese manufactures, the US.)

The answer? In 2006, up to 24% of sulfate concentrations over the western United States were generated in the Chinese production of goods for export to the US.[5] Applying these findings to the more recent study, it’s likely that a significant percentage of the Asian nitrogen oxides now choking the US West were also emitted in the production of goods destined for the US.
