3.6. Carbon Dioxide Emissions by Miles Traveled Groups with 90,000 SpectatorsFor H3b, a hypothetical 90,000 seating capacity stadium scenario for both on-CFE and off-CFE wascreated and the CO2 emissions extrapolated by using the mean CO2 emissions per person and numberof spectators in each mile traveled group by stadium location, as shown in Equation (2). Over 90% ofthe on-CFE 90,000 capacity stadium model emissions are from the spectators traveling the furthest,representing about one-third of on-CFE spectators. In total, off-CFE had approximately one-third of theCO2 emissions of the on-CFE. The CO2 emissions per miles traveled group are presented in Figure 3
