The city is not the problem; the city is the solution.

Every city has to deal with the problem of cars and public transport.

There is no endeavor more noble than the attempt to achieve a collective dream. When a city accepts as a mandate its quality of life, when it respects the people who live in it, when it respects the environment, when it prepares for future generations, the people share the responsibility for that mandate. This shared cause is the only way to achieve that collective dream.

I always try to say, 'If you want to help the environment, try to do just two things. One, use less of your car. Second, separate your garbage.'

We can’t have landfills forever and we can’t ask others to accept our trash.

If you want creativity, take a zero off your budget. If you want sustainability, take off two zeros.

A city is like a family portrait - you don't tear it up if you don't like your uncle's nose.
