4.4. Future ResearchThe ongoing research only examined the impact of spectator’s transportation choices whentraveling to a sports event. To better understand the total impact of collegiate sporting events takingplace at on-CFE and off-CFE, further research should focus on CO2 emissions generated by the facilities’operation considering factors such as energy usage, water usage, and activities of participants andspectators during the sporting event. Future studies should also focus on generation of waste and foodand beverage consumption. This will generate a better estimate of the overall impact that collegiatefootball events have on CO2 emissions and the environment. The survey was limited, and a futuresurvey should gather more information on, for example, why the specific transportation mode waschosen. A future study should be conducted to explore the environmental impacts of an off-CFE thatis in a high-density area.Finally, studies in the US and Canada found distances traveled are greater on average than inEngland [18]. The average travel distance of spectator’s roundtrip travel was 116 miles or 186.7 km,comparable to Edwards and colleagues, who found an average travel distance of 124 miles or 199.8km and Dolf and colleagues, who found an average travel distance of 116 miles or 186 km [4,17].Roundtrip travel to football (soccer) events in England was found to be 25.8 miles or 41.5 km [18].It is not clear if the differences are primarily caused by location, i.e., North America versus UnitedKingdom, or the context, i.e., collegiate versus professional.
