Green cities are a subject that really inspire me, so much so that I recently set up a green backpacker travel website, www.jamblemag.co.uk [1] and an important section of the site are the green city guides - which offer tips on eco-friendly city accommodation, attractions, shops etc.

So far we've featured Cardiff and Bilbao (we're still very new!) but I was just wondering if any of you have travelled to any cities across the globe that stood out as being particulalry green?
