The concept of the Ecological Footprint has become a popular and increasingly used approach in environmental policy and planning, for western cities in particular. The concept is useful not least as a metaphor that effectively communicates the message that environmental impacts extend beyond the built area of cities. However, the use of Ecological Footprint analysis as a measuring tool is problematic, particularly when it is used as a tool for comparisons between jurisdictions. This paper sets out the benefits of the concept, indicates its history and use, and offers a sympathetic critique of both the theory and practice of Ecological Footprints. We believe this is necessary so that policy makers thinking of adopting this approach are aware of its strengths and limitations, and avoid using the concept in a manner that may be misleading.
