The CA-CP Campus Carbon Calculator was recommended in the ACUPCC reporting system instructions. The CA-CP tool was also used because of its ease of use by interested parties and it was comprehensive, and easily accessible.

CA-CP Campus Carbon Calculator's default emissions coefficients.

Campus staff supervised an external consultant who assisted them with identifying and collecting data for the inventory. Campus staff included:
John Frischmann, Acting Buildings and Grounds Director
Joe Teff, Safety Administrator
Roger Spieker, Utility Plant Engineer
Jeff Wagner, Business Office Director
Ron Van Heuveln, Physical Plant supervisor

Inventory data was collected from a wide variety of campus and vendor sources for several categories of greenhouse gas emission activities:

• Energy use for heating and cooling (including purchased utilities)
• Commuter transportation (including automobile, bus and shuttle use)
• SCSU vehicle fleet fuel purchases
• University Business Air Travel
• University Business travel in private vehicles
• Usage of nitrogen-containing agricultural fertilizers
• Fugitive emissions of halogenated refrigerants

Data collection for each of these categories is discussed in greater detail below.

• Energy use for heating and cooling, including electrical energy purchase

Stationary combustion was a significant source of SCSU GHG emissions. These emissions are produced by the combustion of natural gas, propane gas, #6 Fuel oil, and diesel fuel at the central power plant and at the Minnesota Highway Center as well as from the combustion of fossil fuels by Xcel Energy the utility company providing purchased electricity to the campus. Data collected for this category included the total purchased kWh of electricity from Xcel and the total of purchased fuel for the on campus boilers or other stationary sources.

• Commuter transportation

A 2002 parking survey to provide information about a potential parking ramp had data related to faculty, staff and student commuting patterns. Additionally, a student survey in April 2004 also asked students similiar questions regarding their commuting habits. Using this data, we were able extrapolate the percentage, and the average number of days that staff, faculty, and students drove to campus. Human Resources provided information which outlined generally where staff and faculty lived, and that information was edited and used to provide an average commute distance for faculty and staff. Reliable data on where students live while attending SCSU was not available, so estiamtes were used to arrive at an average commute distance for students. Averge weeks per year that each group commuted to campus was calculated using school and holiday calendars.

Since all SCSU faculty, staff and students swipe their ID to ride on the MetroBus system, we were able to get gross miles traveled by SCSU students or personnel. Since the data could not be separated into faculty, staff or students, MetroBus helped us estimate how to separate this information into the three groups.

• SCSU vehicle fleet usage

Data on the SCSU vehicle fleet was collected in the form of total usage of gasoline, E85, Biodeisel or diesel fuel used in these vehicles.

• University Business Air Travel

Flight mileage for the students in the Student Abroad program was recieved by that program. Air Travel miles for other air travel was not available, so the Business Office provided the total cost of air travel and this was converted to miles using a conversion factor provided by the Association for the Advancement of Sustainability in Higher Education.

• University Business travel in private vehicles

Specific information for SCSU business travel miles in either private vehicles or rental vehicles was not available. The Business office provided dollar amounts of total reimbursement for travel and these were converted to miles using IRS reimbursement rates at the time of the travel.

• Usage of nitrogen-containing agricultural fertilizers

Fertilizer usage data included type of fertilizer, nitrogen content, and total amount used.

• Fugitive emissions of halogenated refrigerants

Halogenated refrigerants, such as HFCs and HCFCs, are used throughout campus and can be released due to leaks or equipment repairs. Data on specific refrigerants and their respective fugitive emissions were provided by SCSU Facilities.

Results of this inventory are highly contingent on the availability and quality of the data on which emissions calculations are based. In some cases data were not available to provide a complete historical perspective without assumptions or extrapolation. Where multiple years of data were available, they were extrapolated forward or backward where possible.

Business travel mileage data was minimally available, so nearly all business travel miles were determined using conversion factors from dollars to miles.

Very little specific information was available regarding the commuting habits of the faculty, staff and students. The two surveys mentioned above at least provided a baseline from which to work to determine frequency and percentages of those who drive to campus. Determination of the average travel distance, and the average number of travel weeks were educated assumptions based on the minimal information available.
