 The S2 scenario - this scenario is based on the introduction of additional technical measures for road vehicles to improve the efficiency of motors and decrease fuel consumption. This scenario implies an average reduction in the intensity of all types of vehicles by 0.5%, a significant decrease in the share of diesel and petrol vehicles in passenger kilometers at the expense of the increased share of electric vehicles by 25% by 2050, as well as a decrease in the share of passenger vehicles per passenger kilometer and increase of bus transport for approximately 13% by 2050. Another assumption is increase in the share of electric and the decrease in diesel locomotives by 10% by 2050. Improvement of the quality of fuel is assumed, as well as improvement of the road infrastructure. Reduction in the volume of ton/k is assumed in the area of freight transport and the increase in rail ones for about 12% by 2050. An important element of this scenario is the reduction of the average age of road vehicles to 12 years by 2025. The main objective of this scenario is to reduce the emission coefficient from 185g of CO/km in the base year to 150 g of C0/km in 2025, with a further reduction to 130g of C0/km by 2040. In addition, the introduction, implementation and enforcement of EU directives in the field of transport by 2025 are also assumed.
