Cities and the SDGs: Realities and possibilities of local engagement in global frameworks.

City action is critical to achieving global visions for sustainability such as the UN's Sustainable Development Goals (SDGs). However, SDG 'localisation' is complex procedure, with divergent outcomes depending on context and diverse city processes. This paper considers the operational challenges faced by city actors in taking on the SDGs, and subsequent implications for initiating local (and global) sustainability transitions.
