Many studies are assessing the climate change effect of vehicles and are especially set up to find ways to reduce CO2 emissions [29,41]. However, there are other important environmental impacts to consider. The respiratory effects of the different family car technologies have been compared in Figure 3. Contrarily to the GHE, the E85 sugar cane technology has the highest impact on respiratory effects. This is mainly due to the burning of the sugar cane field before the harvest. The main pollutants emitted during the field burning are carbon monoxide, methane and particles [42]. It is followed by the B100 (RME) vehicle. The high respiratory effect of the B100 (RME) vehicle is mainly due to the emission of ammonia and nitrogen oxides which are directly linked to the use of nitrogen based mineral fertilizers. The best score in this impact category goes to the CNG vehicle. The production of the natural gas has relatively low emission for all the considered pollutants in this category. This is also true for the direct emissions of the CNG vehicle. The CNG technology is followed by the BEV.
