In recent years, the implementation of many European-multinational funded projects has occurred with the participation of the academic community. The impact of such consortia in promoting the European dimension and the acquisition of a common European identity has enriched the international literature. However, research approaches that holistically relate cross-country European programmes to capture their impact on university curricula, as well as on entrepreneurship, are lacking. This study focuses on the impact of four European collaborative projects that engaged the academic community in upgrading higher education programmes towards sustainable entrepreneurship. Specifically, it connects EU projects with the areas of best practices, promotion of cooperation, exchange of learning practices, acquisition of skills and competencies, and development of a European identity. In this regard, it examines the diffusion of European policies through existing pipelines, identifies the factors that act as incentives and disincentives, and concludes with policy suggestions.
