- New Delhi
Air pollution in these cities is five to six times as high as levels that the World Health Organization considers safe and at least three times as high as levels in the largest European and American cities.
The list was compiled by the Asian Development Bank and presented at the Better Air Quality conference in Yogyakarta, Indonesia last week. We haven’t seen the full rankings so we don’t know where Shanghai ranks, but our money is on the top 10.
