The STARS submission form would not allow us to include percentage numbers for the above fields, which did not up to 100%. As a result, some percentage points were added to the above fields, so that the fields added up to 100%. The true percentage outcomes from the university-wide survey were as follows:
- The percentage (0-100) of institution's employees that use more sustainable commuting options = 29%
- The percentage (0-100) of institution’s employees who commute with only the driver in the vehicle (excluding motorcycles and scooters) as their primary method of transportation = 68%
- The percentage (0-100) of institution’s employees who walk, bicycle, or use other non-motorized means as their primary method of transportation. Please note that this may include on-campus residents = 10 %
- The percentage (0-100) of institution’s employees who vanpool or carpool as their primary method of transportation = 10%
- The percentage (0-100) of institution’s employees who take a campus shuttle or public transportation as their primary method of transportation = 9%
