The purpose of this article is to study the possibilities of introducing carsharing as an effective tool for the development of sustainable urban mobility in Ukrainian cities, using Ternopil as a case study. The research aims to identify the key factors influencing the successful functioning of carsharing systems, to develop an approach for assessing the costs of their implementation, and to propose optimal locations for carsharing stations within the city’s transport network. Particular attention is paid to reducing environmental impacts, decreasing the number of private cars, and increasing the efficiency of urban land use. The article analyzes current trends in the development of the carsharing market in Ukraine and worldwide, defines the main organizational models (Free-floating, Peer-to-peer, Fractional), and assesses their potential adaptation to the conditions of Ukrainian cities. A systematic review of scientific studies confirms the feasibility of integrating carsharing with public transport and highlights the potential of using electric vehicles to reduce CO₂ emissions. A mathematical formulation of the problem of cost estimation for launching and operating a carsharing company is developed, covering both initial and operational expenses related to vehicle procurement, station setup, technical maintenance, insurance, and marketing. Optimal locations for carsharing stations in Ternopil (the bus terminal, the “Epicenter” shopping mall, and the railway station) are proposed, taking into account passenger flows, population density, and integration with the city’s transport network. The presented calculations confirm the economic efficiency of this model, as well as its ecological and social significance. The findings indicate that the introduction of carsharing can significantly improve the transport situation in Ternopil, reduce traffic congestion, and enhance the quality of life of residents. It was established that one carsharing vehicle can replace up to 10–15 private cars, which reduces the load on road infrastructure and lowers harmful emissions. The study demonstrates that the most promising direction of development is the use of electric vehicles in carsharing fleets, which aligns with the concepts of “smart city” and sustainable development. For effective implementation of carsharing, it is necessary to ensure the financial affordability of the service, create a supportive regulatory framework, and provide integration with other modes of urban transport.
