Ecological Footprint: Informative and evolving – A response to van den Bergh and Grazi (2014)

Abstract Ecological Footprint accounting is used to track human demand on the Earth's biological resource flows, and compares that demand with the Earth's capacity to generate these flows. It is an evolving tool which has undergone many improvements alongside advancements in science and in response to critical review. Here we respond to van den Bergh and Grazi's recent points of criticism toward Ecological Footprint accounting. While the authors suggest that new criticism is accumulating, the main issues appear to be the same. We suggest that the majority of the criticism is derived from the misconception that the Ecological Footprint measures land “use,” which cannot exceed land availability. In response to these criticisms, we aim here to summarize and further clarify the major points of debate and confusion and allow readers to determine the relevance of these issues. We conclude that much of the prior discussion and many of the points repeated here reflect a divergence in general philosophical or semantic perspectives.
