The concept of sustainable urbanisation is a wide term and very common in recent academic works and spatial planning policy documents, especially in relation to zero-net land discussion. One group of measures aimed at sustainable urbanisation is green urban renewal, which is addressed to varying degrees in different strategic documents at international and national levels. This paper aims to provide a more detailed overview of those strategic documents at the European Union level, providing the context of the new planning instrument for achieving sustainable urbanisation in the Republic of Croatia—green urban renewal strategies. The results of scientific research conducted within the ESPON SUPER project are presented, framing the sustainable urbanisation discourse and practices. SUPER project created a comprehensive framework for assessing the sustainability of different forms of urbanisation and produced a handbook for planners and decision-makers in spatial planning on sustainable urbanisation practices. A special focus of the article is placed on the relationship between green urban renewal strategies and the principles of New European Bauhaus. This relationship is examined through the lens of a handbook that has been developed to enhance the implementation potential of the strategies and promote its components and possible applications.
