Climate change is widely considered as the biggest environmental challenge facing the world today. No matter which side of the fence you’re on, the public and commercial sector have a huge role to play.

"Four years ago we passed the point when, for the first time in history, more people live in cities than don't.

That's what makes the challenge of designing better cities so urgent."
