By Alex Jensen for Local Futures - 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]
