Sustainability and digitalization both require major transitions in our world and the way we imagine them. Digitalization is considered to be the engine that alters sustainability. However, it is not yet known whether and to what extent this digital transformation facilitates or hinders the development of a more sustainable world. The aim of this paper is to shed light on the implications of digitalization for sustainable development in Romania and to provide answers to the following questions: how does digitalization affect the most important pillars of sustainability? How can digital technology help to achieve the Sustainable Development Goals in the next period? These key issues are of immediate practical relevance and therefore need to be addressed by researchers and decision-makers alike. In order to achieve this objective, this research examines the relationship between digitalization and sustainable development, in the specific case of Romania, and examines how digital performance affects the main components of sustainable development, pursued on the basis of the following sustainable development objectives: non-poverty, good health and well-being, gender equality, decent work and economic growth, At the same time, it examines the most important measures for evaluating the level of digitalization of countries (more specifically, the Digital Economy and Society Index DESI methodology) and sustainable development at the macro-economic level (through the Sustainable Development Goals Index SDGI components).
