This paper aims to contribute to a burgeoning dialogue on evaluating the sustainability of sport mega-events by introducing three strategies for implementing the International Olympic Committee's (IOC's) Olympic Games Impact (OGI) study. The three techniques are bundling/leveraging, before-after control and sustainability scorecards. This paper begins by offering a twofold definition of OGI, one based on the OGI Technical Manual and one based on the author's experience undertaking this initiative. Second, it presents and discusses the OGI critiques that exist in the sport mega-event impact literature. Although only recently implemented, critical analyses of the OGI methodology have already produced a handful of critiques. Third, the experience of applying OGI in an examination of the 2010 Games is the grounds for suggesting two new critiques. Fourth, the paper describes, using empirical data from 2010, how the OGI researchers have addressed the methodological critiques by: (1) connecting indicator data to public policy objectives; (2) positing a provisional means to create a sustainability standard; and (3) comparing changes in the indicator data in the host to nonhost jurisdictions. This article would be of interest to future prospective Olympic host cities, researchers of mega-events and their impacts and practitioners who evaluate urban sustainability.
