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.

The design of a city is like a strange archeology.

Cities are not problems. They are solutions.

A lot of people assume that the expensive ideas are the most effective ones, but that is simply not true.

Curitiba is not a paradise. We have all the problems that most Latin American cities have. We have slums. We have the same difficulties, but the big difference is the respect given by people due to the quality of the services which are provided.

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.
