There is a lot to like about living in Washington, D.C. I am lucky enough to live in a city with reliable public transport, well-kept parks and friendly neighbors. And perhaps my biggest blessing is that my city enjoys good air quality. Typing “Washington D.C.” into BreatheLife’s website reveals that air pollution in my city is 10 percent below the World Health Organization’s guidelines.
Around the world, not all urbanites can say the same thing. In fact, 92 percent of the world’s population live in places where air quality levels exceed WHO guidelines. And startlingly, air pollution – both household and ambient – caused 6.4 million deaths worldwide in 2015, with most of the burden of disease occurring in low- and middle-income countries. Taking an economic perspective, the World Bank and Institute for Health Metrics and Evaluation (IHME) estimate that air-pollution-related deaths cost about $5.11 trillion in welfare losses worldwide.
