This Greenhouse Gas Inventory was submitted as part of the College's activities in support of the American College and University President's Climate Committment.
Faculty and student research teams carefully analyzed the amount and sources of energy used by the College over the course of 2008. Factors included in this inventory fell into three categories: direct emissions, indirect emissions and "community" emissions from living on or commuting to campus.
Campus operations that are directly responsible for the production of carbon dioxide were assessed through a number of different methods. A few that were checked are:
- Building Energy Use: Amounts of electricity and natural gas consumed, as well as the amount that is offset by solar electricity generated on campus.
- Indoor Lighting: The number & type of lighting fixtures was examined.The amount of light each room receives was measured through the use of a light meter.
- Outdoor Lighting: The amount and effectiveness of the nighttime outdoor lighting was measured.
- Computer Labs: The amount of time computers were left on and unused was quantified.
- Landscaping: The amount of manicured lawn on campus was measured and the amount of energy and chemicals used to maintain lawn was calculated.
- Waste: The percentage of recyclable materials mixed in with the trash was determined through spot checks of trash and recycling bins across campus.
By examining the products that Stockton buys, we determined the amount of carbon dioxide produced for which Stockton is indirectly responsible. The college’s purchasing records were meticulously examined and a carbon footprint detailing the amount of carbon dioxide released through the manufacture and transportation of each product determined. This was done for everything from pencils to lawnmowers. We also looked at the purchasing records of Chartwells, the campus food service provider. Each food item and product that Chartwells buys was similarly analyzed.
Campus "community" emissions:
The final piece of the puzzle is the amount of carbon dioxide each member of the Stockton community is responsible for by living or working at or commuting to Stockton. Surveys were conducted among apartment residents, dorm residents, commuter students, faculty, and staff. Questions were asked on recycling habits, energy use, and transportation choices. A selected apartment/dorm room was equipped with data loggers to record energy use for comparison to survey data.
