In this unprecedented era of increasing urbanization and the context of the 2030 Agenda for Sustainable Development, the Paris Agreement, the UN Framework Convention on Climate Change and other global development agreements and frameworks, cities should be well-planned and well-managed. Therefore, climate-smart urbanization can be a powerful tool for sustainable development in developing countries. The broader objective of the SmartWB project is to improve the quality of higher education in the climate-smart urban development (CSUD) field, strengthen its relevance for the labor market and society, enhance relations between HEIs in WB partner countries (Albania, Bosnia and Herzegovina and Montenegro) and the economic and social environment by establishing a technological platform for cooperation, exchange of knowledge, experience and good practices, modernizing universities’ courses in line with EU trends and improving the level of competencies and skills of teaching staff. This broader objective fully complies with the priorities of the Capacity Building projects within the Erasmus+ program, i.e., Green Deal.
