Sustainble Communities of Northern Europe

I am planning a brief trip through Northern Europe.  A flying visit set of by the acceptance of my paper on organisational sustainabilityy at the World Sustainable Conference in Helsinki in late October.

I have but 4 weeks till departure to locate the best sustainable communities to visit in London, Paris, Copenhagen (or Kobenhavn), Stockholm and Helsinki; all within 18 days, of which 4 are spent at the conference. 



Rooftop Gardens

 I am getting distracted though, by all manor of interesting sites. Like the sustainable rooftop garden in London central, surrounding the Babylon restaurant.

Organically managed gardens on the 6th floor overlooking central London

Looks like lunch is covered...
