This was achieved by introducing participatory democracy, the integration of public environmental management policies and the regeneration of public spaces. The city of Curitiba provides the world with a model of how to integrate sustainable transport considerations with the development of business, road infrastructure, and local communities. This has been actively and successfully pursued by the local authorities.
