there is a Danish architect called Tony Andersen who was educated by Bill in the 80s I think, he is still very active having co-founded the recent global civil society event called Klimaforum09 in Copenhagen during COP15.
Tony and others have also developed a global strategy for addressing climate change called 10 000 Trees: A Global Strategy for Permaforestry
