Copenhagen certainly aspires to be a green city, but, to me, it seems to be just a large, bustling, urban area. Okay, granted, you can spot wind turbines poking up behind 15th century buildings. And, of course, there is the Lillgrund wind farm in the Oresund, between Sweden and Denmark. Copenhagen's published goal is to not only be carbon neutral but to also provide the world's best urban environment by 2015.
