Harvard/Nanjing study: China’s war on PM2.5 pollution is causing more severe ozone pollution

Green Car Congress

In early 2013, the Chinese government declared a war on air pollution and began instituting stringent policies to regulate the emissions of PM 2.5. pollution is falling, harmful ground-level ozone pollution is on the rise, especially in large cities. Over the course of five years, PM 2.5 Ke Li, Daniel J. 1812168116.

Study finds power law scaling relationship between urban population and NO2 pollution

Green Car Congress

The approximate linear relationship for each region is notable, suggesting that the dependence of urban NO 2 pollution upon population follows a power law scaling with population. Even though larger cities are typically more energy efficient with lower per-capita emissions, more people still translates to more pollution.) ppb (India).
