The transport sector is a source of significant carbon emissions. While individual transportation has yet to become a target area for emissions reduction, mass transportation systems have the potential to replace part of the individual transport and thereby reduce emissions. In busses, trains, metros and even in cable cars different initiatives are introduced, either for more efficient operation or for recovery of brake energy.
Shifting from fossil based diesel to biodiesel is a relatively simple technology. Ethanol is an alternative that may be added both to diesel and petrol, and some countries such as Brazil, in particular, have extensive experience with ethanol fuel for transportation. Biofuels are often seen as competition to food production, which is why second generation technology employing enzymes to extract sugar from agricultural waste is being developed.

CDM projects succeed under the following two main areas of activity: 

  • Public Transportation 
  • Alternative Fuels Public Transportation
Choose Sublevel :
  • Alternative-Fuels
  • Public Transportation
  • Case:
    BRT Bogotá, Colombia: TransMilenio Phase II to IV

    The project involves the establishment of a sustainable mass urban transport system. The system consists of large capacity busses, which will work in a new infrastructure where the busses will be operating in dedicated lanes. The infrastructure will also support easy access to the platforms where passengers are able to board or disembark the vehicles.
    The infrastructural changes will also include a ticketing system which allows pre-board ticketing. The general structure of the Bus Rapid Transit system also involves an improved bus management system moving from many independent enterprises competing at bus-to-bus level to a consolidated structure with formal enterprises competing for concessions.
