He transformed the city of Curitiba, Brazil while he was mayor there and now helps urban planners across the world build and improve cities.

Last night at the Nob Hill Masonic Center Auditorium in San Francisco, the Ecocity World Summit hosted San Francisco Mayor Gavin Newsom and former Mayor of Curitiba, Brazil, now Governor of Paraná Jaime Lerner.
