The progress of the modern society is reflected in all areas of the surrounding world. It stimulates economic growth, facilitates social integration and enhances quality of life. The evolution of society in the twenty-first century has many constructive results, but it also inflicts a number of damages to atmospheric and terrestrial layers, aquatic spaces, the flora and the fauna. As the transport sector is a significant factor in the modern processes, which emits a high percentage of harmful emissions that disrupt the ecological balance in nature, it is necessary to proceed with future development in the context of sustainable development. This report aims to give an overview of the essence of the Bulgarian transport sector, to look at some of the key indicators for sustainable transport development and to identify opportunities for sustainable transport development in Bulgaria. The main indicators for the sustainable development of Bulgaria addressed in this report are: the indicators aiming at ensuring high mobility of goods and passengers, the indicators aiming at reducing the harmful impact of transport, the indicator examining the safety and security of transport, as well as the ”Indicator of the Environment”, measured on the basis of the prices of transport service providers in the country. At the end of the report, the key opportunities for the sustainable development of Bulgaria are being examined, and it can be suggested that the development and the maintenance of the transport infrastructure is a crucial factor for the achievement of sustainable transport development.
