Resumen
This article creates a link between the general term of green urban economy and sectoral exemplification of sustainability in transport. The objective is to prove that a green city cannot exist without sustainable mobility and complex actions at different decision-making levels are needed. The authors start from discussing the terms of green economy, green urban economy, and sectoral sustainability. The genesis and development of the green urban economy concept including the sustainable transport in cities are analysed through literature reviews and critical assessment of policy documents, and both these issues are treated as interconnected and interdependent. Special emphasis is placed on determining the roles of policy makers at different levels (international, national, regional and local) equipped with appropriate policy instruments. As a case study at the local level, the development of electric cars (EV) in Norway is presented. The article argues that transport solutions can be recognised as essential elements at each level of interaction in urban policy and sustainable mobility solutions can determine the implementation efficiency of a whole green city package.
