London and Paris among cities with highest number of avoided deaths thanks to lower pollution in first lockdown
More than 800 lives may have been saved across Europe thanks to better air quality in the first phase of Covid lockdowns, research suggests.
Measures brought in to stem the rise in infections resulted in far fewer cars and lorries on roads, which had the biggest impact on reducing deaths, according to the study led by experts from the London School of Hygiene and Tropical Medicine (LSHTM).
