With good load factors, the energetic efficiency of public transport is not to be proven. Their responsibility in all of the air pollution is very limited in France and Europe; In "Ile de France" the 4000 RATP busses account for 1/3 of the motorised surface trips and contribute to less than 4% of the pollutant emissions (source ADEME 96). However busses in particular are seen as big polluting responsible. These vehicles tend to concentrate the polluting emissions in the massively populated areas, this creating localised pollution, particularly visible and fatal. The image of buses hardly improves. Environmental concerns are becoming for the various political authorities very important, in term of urban quality of life. The goal of this presentation is to present an overview of the different solutions, which are today available for clean busses.
