The social solidarity economy (SSE) has been gaining in increasing economic, social, and political significance in the EU recently. Deep environmental, social and economic crises caused by the effects of globalization of capitalism, distorted welfare models have forced many subjects of power and society to consider the social and solidarity economy of the ways of solving these crises. Our project is based on the conviction that EU experience in SSE offers comparative advantages in addressing economic, social, political, managerial, and environmental issues in Ukraine. It illustrates potential by examining the role of SSE in selected issue areas which, we believe, are central to the challenge of socially sustainable development in the early 21st century. Sumy State University has a strong scientific and technical base for the implementation of this project participates in many projects organized by the EU on academic mobility, compatible research, etc. Over the past 20 years, extensive experience has been gained in European integration processes and the study of European experience. Project « SSExpEU» is created from the method of encouraging students to master the progressive strand of solidarization of the economy in the EU and the possibilities of its implementation in Ukraine, attracting young and experienced specialists within the framework of this project will allow developing innovative methods in teaching and research on European integration. The main effects for participants are expected to be increased awareness of European studies, which will bring added value in their future careers, create prerequisites for solidarization of the society, and support young teachers in increasing their professional growth. We propose to achieve the objectives of the project using the following types of activities: lectures, seminars, workshops, intensive training involving other universities, organizing a round table with business representatives, etc.
