How do these results fit with other Ecological Footprint studies?
The results have 100% comparability and consistency with the Global Footprint Network (“standard”) accounts. As described above, the calculation methodology has recently changed which means that the new results are not directly comparable with older studies (on average, Footprint values are now slightly lower than previously as we have eliminated possible double counting in the previous method).
There may also be differences to studies from other Footprint consultancies. However, Footprint practitioners from the UK and worldwide have joined in an effort to create a standard procedure for Footprint calculations. The first set of standards is due to be published in June 2006. The present accounts comply with the draft standards. For more information visit the Footprint Standards website.
Unfortunately it is not easy to adjust former Footprint studies for comparability as the old studies use different categories and classifications. Simple updating is not possible in most cases.
