Air quality in New York and many other US cities has been getting better since the 1970s. One factor in New York's recent improvement: a phase-out of heavily polluting heating oil in older buildings.
Those living in American cities may not be able to go out for a nonmetaphorical “breath of fresh air” quite yet, but there are signs of a remarkable rise in the quality of the nation’s air – even though pollution remains a threat to people’s health and contributes to global warming, experts say.
The air quality in New York is the best it has been in 50 years, Mayor Michael Bloomberg announced Thursday.
And in Washington, D.C., the air surrounding the nation’s capital has shown “major improvement” the past few years, according to Metropolitan Washington Council of Governments, a nonprofit association of area leaders. The region didn’t have a single “code red” alert for dangerous air quality this summer – only the second time this has happened in 16 years, and the first since 2009.
