Abstract:
The objective of this study was to investigate if biofuel can substitute 100% of fossil fuel in the Austrian individual traffic by 2020 assuming an autarkic production of food. But for this it was assumed, that the potential agricultural area is prior used for food production. First of all the theoretical need of agricultural area for nutrition was upraised and self calculated and it accounts between 1.500 and 2.000 m2 per person and year. On the residual agricultural area three different systems for crop rotation are used for cropland and so the theoretical production potential of biofuels is calculated for 2020. Additionally, the theoretical production of biofuels from grassland and 25 % of biogenous residual material (as for example used oil or matured forest including landfill gas) is included. Finally, these potentials of the production of biofuels are summed up. The second part was, to figure out the theoretical demand of fossil fuel in four road performance forecast, including five models of theoretical demand of fossil fuel. By combination of these facts, the theoretical potential to substitute fossil fuel and the theoretical potential to save CO2-emissions were calculated. These calculations showed that the theoretical potential to substitute 100 % of fossil fuel in the Austrian individual traffic is possible. But only by using the least road performance (“WAM”) in combination with smallest need of fuels (“3-liter-car”). The 3-liter-car-technology is state of the art, and this technology should be binding as maximal-need-technology on EU-level. But also the reduction of road performance, e.g. by shift traffic to railway, or forcing going by food or by bike and also public transport has to be forced.
