Residents of just four American metropolitan areas have had regular access to healthy air in recent years. Those four places — Burlington-South Burlington, Vt.; Honolulu; Elmira-Corning, N.Y.; and Salinas, Calif. — had the pleasure of breathing air consistently free of unhealthy ozone, short-term particle and year-round particle pollution from 2012 to 2014,according to a new national air quality report card from the American Lung Association.

Actually, air quality has significantly improved in American cities since the passing of the 1970 Clean Air Act and subsequent legislation. This year marked the lowest particle pollution levels in 16 years for all but four of the top 20 most-polluted cities.Still, things remain pretty grim: more...
Beijing is stepping up measures to fight against smog and pollution by building a web of ventilation corridors as one of its plans to combat climate issues, according to municipal authorities.
“Ventilation corridors can improve wind flow through a city so that wind can blow away heat and pollutants, relieving urban heat island effect and air pollution,” Wang Fei, deputy head of Beijing’s urban planning committee, told Xinhua News Agency. — CCTV America
The planned "ventilation corridors" would range from less than 80 meters to more than 500 meters wide and – hopefully – do what their name suggests, providing a conduit for wind to blow away pollutants like particulate matter.Five major corridors are planned for the Chinese capital, running...
The number of premature deaths attributed to particulate pollution has risen, government figures show.
According to Public Health England, the percentage of premature deaths attributable to minute particles known as PM2.5s rose to 5.3% in 2013 in England from 5.1% in 2012. The death rate in London rose to 6.7% from 6.6%. The figures follow significant improvements in air quality across England in 2010 and 2011. — the Guardian

For the first two weeks of the year, private cars with even-numbered license plates are allowed on the roads only on even-numbered dates, and those with odd-numbered plates on odd dates. The restrictions have noticeably reduced traffic in a city with 9 million cars, more than double that of a decade ago.

A red alert should go into effect if there is a prediction that the air quality index will stay above 200 for more than 72 hours. The United States government rates above 200 as “very unhealthy,” and 301 to 500 as “hazardous.” At 7 p.m. Monday, the Beijing municipal reading was 253. [...]
