Who is making progress on cities, climate change, and policy?

I'll ask it once again, who (person or organization) do you think is making good progress on cities, climate change and policy? It can be on any scale - urban intervention, city-wide, sectoral, regional, state, national, supranational, bilateral, multinational...you choose. I want to know who your city-climate change heroes are. You can define action, who does it, how much, what success is, etc. The only caveat is that your nominee should deal with policy somehow - effectively, the rules that allow multiple actors to engage with one another while avoiding public harm (btw, this is such a low bar that I feel it needs a disclaimer - this should not be a standard for public policy!)
