Using Ecological Footprints as a Policy Driver: The Case of Sustainable Construction Planning Policy in London

The heuristic value of the ecological footprint (EF) conceptual device has met with considerable political and civic buy-in at national, regional and local levels. It is seen as particularly valuable for visualizing ecological overshoot but debates about methodological soundness have undermined this potential. This paper examines the emerging opportunities for advanced footprinting approaches that use input-output analysis to test 'what if?' policy scenarios and hence turn EF into a proactive driver for sustainability-oriented policy development. It focuses on the London case and the specific arena of planning policy for sustainable construction.
