Abstract
Practically, the strategic guideline for a transformation of transport sector of the Ukraine’s economy is the reduction of the transport carbon footprint. The decarbonisation policy of the Ukrainian transport sector is characterised in the present paper. Moreover, inefficiency of the current policy is proved. The authors created the mathematical model of structural improvement in road transportations by redistribution of transportations volumes between the motor transport and the railway. Guided by the scenario approach, the three most probable scenarios for traffic optimisation are developed, such as pessimistic, basic, and optimistic. The carbon reduction percentage is computed in each of these scenarios. In addition, the priority vectors of the policy of the structural optimisation of the road transport by redistribution of traffic volumes between the motor transport and the railway are determined.
