A record level of thick, choking smog enveloped Hong Kong for a second day yesterday, prompting calls from enviros and politicians to crack down on the area’s severe air pollution. Sunny, clear skies have become rare in the city in the past year, but yesterday’s air pollution was the worst since measurements began being taken in 1995. Hong Kong’s air problems are blamed on its large fleets of diesel-powered taxis, trucks, and buses, as well as emissions from factories and power plants in other parts of southern China. In recent months, Hong Kong’s business sector has started calling for serious action to improve air quality.
