What they said about Green Cities 2011

"Green Cities conference gets its mojo back," Tina Perinotto.

"It's rare for someone who has been practising 20 or 30 years to go to a sustainability conference and come out with something really inspiring. I thought this was really refreshing" said Stella Whittaker of Manidis Roberts.

"I thought the fishbowl was quite clever. I was very impressed with its ability to get people asking the questions that became part of the discussion," said Alex McKenna of The Warren Centre.
