The study examined how differing collegiate football event locations—an on-campus stadiumwith the characteristics of a high-density area and an off-campus characterized as a low-densityarea—impact CO2 emissions from different transportation modes and distances traveled by spectators.Previous studies have focused on one university [4], mega-sporting events [3,6,16,36–38], and aggregateannual emissions for professional sports [7,18]. The findings revealed both meaningful and insightfulinformation regarding the effects of stadium location, spectator’s transportation choices and milestraveled on CO2 emissions. The results include: (a) the difference in CO2 emissions generated byspectators’ travel; (b) the spectators’ choices of transportation mode; and (c) the different distancesspectators travel to attend a collegiate football event in on- and off-campus settings.
