What happens to people’s health when air pollution is reduced?
West Macedonia in Greece was Europe's leading lignite mining region, and in 2005 its six coal-fired power stations supplied about 60% of the country's electricity. When the mines shut and the plants were cleaned up and closed, researchers had a rare chance to watch what cleaner air does to a population's health. Between 2011 and 2021, as pollution fell, wintertime hospital admissions for heart problems dropped sharply at the main hospitals serving more than 200,000 people. The researchers describe the region as a microcosm of what sustained emission cuts could achieve globally, and it adds to growing evidence that cutting coal use and banning high-polluting vehicles delivers immediate local health benefits, not just distant climate ones.
For you: Worth knowing that cleaner air pays off close to home: cutting local pollution is a heart-health argument, not only a climate one.
