Take a Deep Breath of Fresh Air: See how a strict continuous emission monitoring system can curb air pollution
■As was widely reported in the media, the head of WHO referred to air pollution as “the new tobacco.” And since humans cannot survive without breathing, reducing air pollution has been placed as a top priority globally to reduce the harmful effects caused by—just breathing. In fact, every breath you take could contain any number of harmful pollutants, including particulate matter (PM2.5) and nitrogen oxides (NOx). In their annual report on air pollution, the State of Global Air 2020 reported that air pollution was responsible for 6.67 million deaths worldwide in 2019.
■It’s sad to say, but in cities across the globe, breathing "clean air" has become quite a luxury, with people in some areas of the world waking up to gray skies almost every day of the year. In an ironic twist to the 2020 coronavirus lockdown, skies in some of the most polluted parts of the world cleared up significantly due to the sudden cessation of most daily commutes. Citizens of many cities were treated to the sight of long-invisible skylines as well as the long-forgotten smell of fresh air. The public got a “pleasant” reminder of just how serious the global air pollution problem really is.
■Industry and transportation are the leading sources of global air pollution. In most countries, industry accounts for more than half of the total emissions of some key air pollutants. Air pollution not only affects the health of human beings, it also does significant damage to the Global GDP. That’s why in recent years, governments around the world are taking a more active role in enacting policies that specifically address the need to improve air quality.
