Smog In Santiago Causes Environmental Emergency in Chile

Authorities in Chile’s largest city shut down hundreds of businesses and ordered hundreds of thousands of cars off the streets on Monday as a gray carpet of air pollution forced a declaration of an environmental emergency in the city hosting the Copa America football tournament. The order forced the closure of more than 1,300 Santiago businesses that emit high levels of contaminants. It also parked a large share of the capital region’s estimated 1.7m vehicles, especially older cars.
