The generalization of diesel vehicles is being threatened by the increasing integration of
lower-emission vehicles, and even by the creation of specialized renewable energy/nonpolluting
divisions within large syndicates and public transportation. Is this evolution
compatible with the need to regulate costs? Or inversely is this justified by the increase in
petroleum prices?

1- Public transportation

• A brief summary of the urban and suburban transport situation in the world’s biggest
  cities.
• How are fleets evolving given energy (increasing costs) and environmental
  constraints? Which modes of transport are being chosen (rail, road, a combination of
  road and electric transport…)? How are environmental and economic constraints
  being weighed up? What choices are typically being made by public bodies and
  transport syndicates? How are these choices justified?

2-Company vehicle fleets

• Does one manage an alternative fleet (electric, biodiesel, oil…) differently from a
  diesel fleet? What are the costs and added constraints? Brief summary of the
  composition of vehicle fleets in different countries.
• How to integrate environmental factors into business fleets. What choices to make,
  and on what proportion of the fleet? How to conciliate autonomy, efficacy, economies
  of scale. What financial and tax advantages are in place? How to communicate on
  the environmental gains. Is managing a fleet while integrating environmental factors a
  strong selling point and a valuable addition to brand image?
