Non-road fuel consumption and pollutant emissions FOEN 2008 90 8.6 Marine machinery 8.6.1 Fuel consumption In 2005, the fuel consumption of ships and boats amounted to 36,510 tonnes, with diesel accounting for 61% (22,170 tonnes) and petrol for 39% (14,340 tonnes) (Fig. 46, top). Commercial operations generate the highest proportion of diesel consumption, which largely corresponds to the consumption data provided by major operators for 2005, from which we can estimate the overall consumption by Swiss passenger ships: According to the operators on the lakes of Zurich, Lucerne and Geneva, fuel consumption in 2005 amounted to 3920 tonnes for motor vessels and 3400 tonnes for steamships. These three operators account for 49% (motor vessels) and 89% (steamships) of the mileage of all passenger ships on Switzerland’s lakes. These figures indicate overall consumption in Switzerland of around 8000 tonnes p.a. (motor vessels) and 3800 tonnes p.a. (steamships), and are more or less in line with the results obtained with the calculation model (9200 and 3800 tonnes p.a. respectively) 25 . The fuel consumption of steamships is high compared to their proportion of the overall mileage. This is because the specific consumption of these vessels is several times higher than that of conventional passenger boats. The level of petrol consumption is 14,300 tonnes, 83% of which is attributable to privately operated boats, while fishing and other commercial boats account for the remaining 17%. The proportion of boats equipped with 2-stroke engines is very low (2%). Development of fuel consumption from 1980 to 2020 In the period under review, the fuel consumption of ships and boats only changed very slightly, and we can expect the figure 15 years from now to be similar to the presentday level (Fig. 46, bottom). 25 The consumption factors for steamships were calibrated on the basis of this plausibility consideration.
