Economic, Environmental Interests Compete in a Post-COVID Europe Marthe van der Wolf AMSTERDAM, NETHERLANDS - The coronavirus lockdown in many European countries has led to less pollution. But policy decisions in coming months will make clear if an economic recovery helps or hurts environmental gains. Europe's cities, where streets are usually congested, are now quiet, as people are forced to stay at home due to the coronavirus pandemic. Alberto Gonzalez Ortiz, an air quality expert at the European Environment Agency, says air pollution is down since lockdowns were implemented in cities across the continent. "In some cities, it's from one week to another we see a reduction of more than half of the concentrations. The reductions are not the same in all cities. Because the lockdown measures are not the same or not so intense either in all countries and they have started at different times," Gonzales said. In Europe, 2019 was the hottest year ever recorded. But with millions of people forced to stay home, consuming less and traveling less, there is a reduction in emissions, carbon and air pollution. But countries across the continent want to slowly ease restrictions to get the economy going again. Some people are concerned a quick return to life as it was before COVID-19 might undo newly gained environmental benefits. Imke Lübbeke of the environmental group World Wildlife Fund (WWF) says there is no reason yet to celebrate about environmental gains. .
