Dirty air killed more than half a million people in the EU in 2021, estimates show, and about half of the deaths could have been avoided by cutting pollution to the limits recommended by doctors.
The researchers from the European Environment Agency attributed 253,000 early deaths to concentrations of fine particulates known as PM2.5 that breached the World Health Organization’s maximum guideline limits of 5µg/m3. A further 52,000 deaths came from excessive levels of nitrogen dioxide and 22,000 deaths from short-term exposure to excessive levels of ozone.
