Some of my guesses for cities with at least 500,000 people:

Vancouver, Canada
Honolulu, Hawaii
Perth, Austrailia
Hong Kong, China

For countries:

Norway
Iceland
Sweden
Canada



But I would like to see what others think and if there are any informative website links related to this thread subject.

It's very polluted and dirty.

It would be the most sparsely populated countries/cities in relation to its area, with little or none industries.

San Francisco has cleaner air than most cities of it's population size (750K). There is very little heavy industry left in the city. The almost constant ocean breeze blowing in off the Pacific push whatever air pollution that is produced in SF towards the east. Much of the public transportation runs on electric power (subway, streetcars, cable cars, trolley buses).

Thanks for all the posts!

stolpioni:

How is it possible for Kong Kong to be so polluted when it gets 100 INCHES of precipitation per year on average(Thats double New York City and Vancouver's precipitation per year), is surrounded by ocean on three sides, seems to have good public transportation, and has so many green spaces within its city limits? It seems like it would be a rather clean and not polluted city because of that. I dont know any other city in the world that gets that much rain, and rain can help so much in air and water quality.

To elnina: Thanks for all the links! Im definitely not surprised that cities in Canada and Scandinavia did well, especially Vancouver, Stockholm, Oslo, etc. I disagree with some of the places selected though as well as some places not being mentioned.
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

recycled: Thats true about San Francisco. That also seems true about Seattle and Portland, except they are more inland so dont get as much help with ocean breezed. But they go get more precipitation which helps with air and water quality.

My guess would be that Hong Kong has a high density of buildings/people/cars you name it on a comparably small area, and thats whats making it polluted.
I remember both me and a friend of mine had black tar coming out of our throats when coughing after a day in the city.
When did that happen in LA for example, which is known for beeing heavily polluted.

To stolpioni: Which month did you visit Hong Kong? Its hard to believe its THAT polluted because of the reasons I said before. Maybe you went to Hong Kong the worst time of the year for pollution or something like that.

November-February seems like the worst time for pollution in Hong Kong because thats the dry season for precipitation.

Air pollution in Hong Kong - Wikipedia, the free encyclopedia
Quote:
Air pollution in Hong Kong is considered a serious problem. Visibility is currently less than eight kilometers for 30% of the year. Cases of asthma and bronchial infections have soared in recent years due to reduced air quality.
The article includes all the information you need as to why and its effects.

To poxonnyou:

Why is the air pollution so bad in Hong Kong and London while its so much better in New York City and Tokyo?

JAPAN should be on that list...SWITZERLAND as well.

In North America, Portland Oregon should go on that list...Seattle perhaps...perhaps...
