Assessing the environmental impacts of mega sporting events: Two options?

At a time when public and private agencies recognise the importance of sustainable development, the environmental impacts of mega sporting events are commanding increasing attention. However, despite event sponsors often flagging the importance of environmental as well as socio-economic legacy components, the environmental impacts of events are difficult to assess quantitatively, being complex and often occurring over extended periods. The general assessment issue is particularly acute with regard to mega events such as the Olympic Games and FIFA World Cup. The practical issues mean that any quantitative techniques seeking to assess environmental impacts are likely to be partial in scope. This paper examines two such approaches for quantitative impact assessment of selected environmental externalities connected with visitation at sporting events. The paper considers the use of Ecological Footprint analysis and Environmental Input-Output modelling. It provides examples of the applications of these techniques to discrete sporting events in a UK region, and discusses whether these techniques are appropriate for exploring the environmental impacts of mega events.
