Beijing has long way to go to meet clean air goal, mayor says
Déjà vu as mayor tells congress pollution and population are the most pressing problems - and admits falling short of reduction target

Major obstacles remain if Beijing is to bring air pollution under control, its mayor has warned, while admitting the city fell short of last year's target.
Speaking at the opening of the Beijing Municipal People's Congress on Friday, Wang Anshun said pollution and a growing population were among the most pressing problems to be solved - exactly what he said at the same meeting last year.
The average concentration of fine particulate matter (PM2.5) - the pollutants considered the most dangerous to health - fell by 4 per cent last year, short of the 5 per cent reduction target, he said.
The target was missed even though 392 companies were closed for polluting, 476,000 old vehicles were taken off the road, and 66,000 hectares of green areas were planted.
"We face major difficulties in controlling the population size and are under tight resource and environmental constraints," Wang said. "We still have a long, difficult way to go before we can control air pollution and ease traffic congestion."
