Sustainable urban development:Policy analysis andPolicy analysis and recommendations


Sustainable urban form: Densification in the right places

• Fast growing cities will show massive growth of their urban fabric

• But: greatest potential to re-focus their development strategies through densification (e.g. Vienna, Stockholm)

• Focus areas: mixed use fringes with good public transport• Focus areas: mixed use fringes with good public transport

• Potential impact of densification:

- reducing land consumptionreducing land consumption- combine with energy-reduction through building

improvement - reducing new infrastructure investmentg- improving modal split – reducing energy consumption - keep green spaces, protected areas open - improve urban spatial qualities in fringe areas
