The project develops different scenarios for the introduction of biofuels, based on the technological evolution in vehicle models, the likely biofuel blends on the European markets, and the possible interest of certain end user groups. Based on up-to-date data (complemented with own measurements) of energy use, emissions and cost projections, the practical feasibility and the ecological and economic impact (on micro and macro level) of the introduction of biofuels in Belgium are analysed. Results are used to create a roadmap for the introduction of biofuels in Belgium.
