European Union (EU) transport policy aims to support less polluting and energy-efficient modes of transport at the expense of road transport. Promoting multimodality and shifting towards low-carbon modes is one of the main priorities of the European Commission’s new flagship initiative “European Green Deal”, presented in December 2019. Supported by investments in green technologies, sustainable solutions and new businesses, the Green Deal can act as a new EU growth strategy. One of the measures set out in the element “Accelerating the transition to sustainable and smart mobility” of the Pact is to increase the efficiency of the transport system by prioritising the development of rail and waterborne transport.In response to the new trends in European policy related to improving the efficiency and quality of the transport service, limiting the harmful impact on the environment, and in view of Bulgaria’s fulfilment of the triggering condition for granting EU funds in the period 2021-2027 related to the promotion of multimodality, it is necessary to formulate a concept for the development of combined transport at national level, combined with a package of measures for its implementation. In view of the above, and in connection with Article 57 of the Railway Transport Act, the Ministry of Transport, Information Technology and Communications with this project initiated the development of a National Plan for the Development of Combined Transport by 2030, through which, on the basis of a study carried out, to formulate a long-term vision for the development of combined transport in the country, consistent with the views and attitudes of the transport industry and reflecting the good European practices.
