The sustainable governance of transport systems remains a significant challenge for policy makers worldwide, particularly in cities. Urban areas are developing rapidly from a technological viewpoint, and innovative technologies create new possibilities for smart mobility management. Therefore, this study investigates the relationship between the implementation of the smart city concept and the idea of sustainable transport, particularly with regard to the reduction of transport generated CO 2 emissions. The study estimates CO 2 emissions for different potential scenarios of development for the Warsaw transport system until 2050 using the United Nations' ForFITS (For Future Inland Transport Systems) model. The study also analyses the additional impact on CO 2 emissions of smart city elements as determinants of mobility. The results show that meeting the reduction targets set by the European Union 2011 White Paper on Transport will be challenging, requiring an in-depth transformation of the transport and energy sectors. This study also confirms that smart city solutions can play a crucial role in mitigating transport emissions and meeting reduction goals. The conclusions provide important insights for the design of smart mobility governance and enhance the relationship between transport policy and research. [ABSTRACT FROM AUTHOR]

In recent times, the emergence of coworking spaces (CSs) has changed not only the way workers cooperate, but also how they carry out their activities. This phenomenon, limited mainly to urban areas, has spread heterogeneously across cities. The paper focuses on the location of CSs in Barcelona, Warsaw and Utrecht, three European cities that differ in terms of the typology of creation of these workspaces. In the three analysed cities, CSs are mainly private initiatives, although in Barcelona they are developed by small entrepreneurs, while in Warsaw they are developed by large multinational CS chains. Using K-density (Kd) functions and density maps, we contribute to the empirical literature by identifying how CSs coagglomerate with the service sectors, how CSs are concentrated in core areas of each city and how these factors differ between cities, taking into account the typology of CSs. We found that the CS location and coagglomeration depend on the spatial structure of the city and its development model; therefore, policymakers should take this into account in order to implement appropriate policy measures to attract CSs • CSs agglomerate differently in cities with different levels of urban hierarchy and reveal different CSs location strategies. • The coagglomeration of CSs with Knowledge Intensive Services (KIS) and symbolic knowledge base firms has been confirmed. • Market and high tech KIS with CSs build an urban entrepreneurial ecosystem.
