The transformation of transport is necessary not only for climate protection, but also to increase competitiveness, develop modern technologies in transport, and improve the well-being and quality of life of the population. This article discusses the current state of the transformation of transport and infrastructure to low-emission and ze-ro-emission within EU member states and, in particular, their SMART cities. This arti-cle discusses the challenges, modern technologies, disadvantaged groups, and the overall concept of transformation with the aim of designing the most effective strategy for transport transformation at the SMART cities level. The potential relationship be-tween the position of EU member states in the Climate Change Performance Index ranking and Greenhouse Gas Emissions in the EU is identified and analyzed. The re-sults are reflected at the SMART cities level, confirming that proactive states achieve faster and more effective transport transformation. The conclusion of the article de-fines research trends aimed at improving the level of transport transformation and challenges related to successful transformation at the SMART cities level.
