Governmental responses to air pollution: summary of a study of the implementation ofrodízio in São PauloPrograma de Pós-Graduaçao em Ciência Ambiental da Universidade de São Paulo-PROCAM/USP, Rua do Anfiteatro,181, Colmeia/ Favo 15, 05508-900, Cidade Universitária, São Paulo, Brazil; pjacobi{at}sysnetway.com.br
Stockholm Environment Institute, PO Box 2142, S-103 14 Stockholm, Sweden; email: marianne.kjellen{at}sei.se This paper describes the "rodízio" programme in São Paulo which has sought to reduce air pollution by banning the use of every car for one day a week. After summarizing the serious problems that São Paulo faces from air pollution and the extent to which these are generated by motor vehicles, it describes the difficulties the city authorities faced in getting approval for this programme, including opposition of the press. However, it has still been implemented - for a month in 1996 and for the period June-September in 1997 and 1998 - and accompanied by a large information programme. Its implementation brought significant reductions in some air pollutants and reduced traffic congestion. It also received considerable public support. The paper ends by reflecting on this experience in the light of the need for city authorities to increase information about environmental risks and ensure democratic interaction between local government and citizenry about environmental priorities.
