Severe Beijing smog prompts unusual transparency

BEIJING (AP) — One of Beijing's worst rounds of air pollution kept schoolchildren indoors and sent coughing residents to hospitals Monday, but this time something was different about the murky haze: the government's transparency in talking about it.

While welcomed by residents and environmentalists, Beijing's new openness about smog also put more pressure on the government to address underlying causes, including a lag in efforts to expand Western-style emissions limits to all of the vehicles in Beijing's notoriously thick traffic.
