Williams does not keep detailed records of air travel by faculty and staff. The only estimate of annual air travel was done in fiscal year 2007, based on a sample of 450 tickets which had destination information recorded (out of a total 2200 plane tickets). Student travel to and from campus and for study abroad was also estimated.
Table 1. Estimated air travel and CO2 emissions, FY 2007.
|Category||Approximate cost (dollars)||Number of round trips||Total distance (miles)||Emissions (metric tonnes eC02)|
|Students studying abroad||239||2,297,769||644|
|Faculty and staff||$1,180,000||>2000||9,565,445||2,683|
|Students traveling to and from campus||4,171,400||1,168|
Because Williams doesn’t keep regular or detailed records of air travel, air travel is not currently included in our annual emissions reporting or goals.
