1 TEMPLE UNIVERSITY GREENHOUSE GAS INVENTORY PROGRAM F ISCAL Y EAR 2010 UPDATE prepared by the Office of Sustainability 1913 North Broad Street Philadelphia, PA 04 May 2011

2 FY 2010 GREENHOUSE GAS EMISSIONS UPDATE Temple University (Temple) has prepared a greenhouse gas (GHG) inventory program in support of its participation in the American College and University Presidents Climate Commitment (ACUPCC). This inventory is an update which summarizes Temple s fiscal year 2010 GHG emissions and supplements the previously published inventory for fiscal years 2006 through This inventory quantifies Temple s anthropogenic GHG emissions from energy consumption, waste disposal, agricultural activities, use of chemicals and refrigerants, and commuter transportation choices and tracks emissions of three primary greenhouse gases: carbon dioxide (CO 2), methane (CH 4), and nitrous oxide (N 2O). Using the methodology of Clean Air Cool Planet ecalculator tool (version 6.6), GHG emissions are expressed in Metric Tons of Carbon Dioxide Equivalents (MTeCO 2). The individual greenhouse gases are converted to carbon dioxide equivalent values using the global warming potential (GWP) of the respective gases to convert them to common units. The total MTeCO 2 is the sum of the emissions from each source. Inventory boundaries and definitions are summarized as follows: GHG Accounting Protocols Organizational Boundary Operational Boundary De minimis threshold Baseline Year Emissions Intensity Metric Reporting Frequency World Resources Institute/World Business Council for Sustainable Development (WRI/WBCSD) GHG accounting protocols in conjunction with the Clean Air Cool Planet (CACP) Campus Carbon Calculator (v6.6) Includes only those campuses where the university has operational control and can enforce a change in policy. Includes: Main, Ambler, Health Sciences, Podiatric and Tyler campuses. Excludes: Temple University Health System and Center City, Harrisburg, Fort Washington and International Campuses. Scope 1 Direct emissions: stationary sources (natural gas, oil, propane), mobile sources (leased/owned University fleet), process sources (application of fertilizer), fugitive sources (refrigerant leakage, usage of CO 2). Scope 2 Indirect emissions (those outside of the organizational boundary) from purchased electricity and steam. Scope 3 Other indirect emissions from employee and student commuting, employee air travel, landfilled solid waste, and transmission and distribution losses. 5% - Emission sources that collectively account for a small percentage of entity-wide emissions (<5%) can be called de minimis and may be approximated. Temple s de minimis sources include mobile sources, process sources, fugitive sources, purchased steam, and landfilled solid waste. Fiscal year (FY 2006). This is the first year for which complete, verifiable emissions data is available. Gross square footage (GSF) and full-time equivalent students (FTE). These are used to normalize emissions to account for institutional growth over time. Fiscal year (July 1 to June 30) reporting.

FY2010 GHG Inventory Update 2

3 INVENTORY RESULTS In FY 2010, Temple University s total gross emissions were 230,567 metric tons of carbon dioxide equivalent (MTeCO 2). Of the total emissions, 48% were attributable to purchased electricity consumption, 25% to stationary sources and 19% to transportation activities with a large portion attributable to commuting. Mobile sources (university fleet), refrigerants, fertilizers, purchased steam, solid waste, and transmission and distribution losses made up the remainder, approximately 8% of the total emissions. Temple s total gross emissions were reduced to a net of 227,511 MTeCO 2 through carbon offsets. The primary emission sources were purchased electricity, stationary combustion, and commuting (student, faculty and staff), collectively accounting for approximately 88% of total annual gross emissions. Data for each emission source was collected in a GHG scorecard (Attachment B) and was used to populate the CA- CP Campus Carbon Calculator. Data sources are summarized in Attachment C. The resulting emission estimates from FY 2006 through FY 2010 are summarized below.

4 TRENDS FROM FY 2009 TO FY 2010 Total gross emissions decreased by 3.2% from FY 2009 to FY Scope 1 emissions decreased by 9.1% and can be attributed primarily to fuel switching (No.6 fuel oil to natural gas). Scope 2 emissions increased by 2.9% and can be attributed to the increase in purchased electricity. Electricity usage increase was mostly likely due to three university buildings being fully online in FY 2010, including Alter Hall (01/2009), the Medical Education Research Building (05/2009) and Tyler School of Art (01/2009). Scope 3 emissions decreased by 7.5% from the reduction of student, faculty and staff commuting miles. In FY 2010, total gross emission intensity per 1000 gross square feet (GSF) declined by 1.9% and total gross emission intensity per full-time equivalent students (FTE) declined by 7.7% relative to FY For reference, average Scope 1-3 gross emission intensities for doctorate-granting universities are MTeCO 2/1000 GSF and 7.81 MTeCO 2/FTE (ACUPCC Reporting System; accessed 12 April 2011). On a per FTE basis, Temple s emission intensity of 7.35 MTeCO 2/FTE is slightly lower than average, whereas on a GSF basis, Temple s emission intensity of MTeCO 2 is slightly higher than average. Overall, Temple s current emission intensities are comparable to peer institutions. Emission Reductions Stationary source emissions, a significant contributor to Temple s emissions, were reduced in FY 2010 by 5,976 MTeCO 2. Again, this reduction is attributed to the decreased use of No. 6 fuel oil which was replaced by natural gas, a cleaner fuel. Another significant reduction occurred in transportation with a 5,258 MTeCO 2 reduction from FY A new transportation survey was conducted during FY 2010 which resulted in reduced commuting miles and fewer emissions (refer to Attachment A). Although differences in survey methodologies from 2007 to 2010 may have played a role in the decrease, university-wide transportation initiatives implemented since the 2007 survey have contributed to changes in commuting habits. These initiatives include the creation of Bike Temple to promote bicycle use and educational campaigns to promote Temple s University Pass Program, employee transit benefits and car pooling/sharing options. Temple increased its compressed natural gas fleet from 10 vehicles in FY 2009 to 16 vehicles in FY This resulted in reduced diesel and gas consumption and decreased emissions of 3.7%. Although a small contributor to Temple s GHG emissions, another notable reduction includes the reduction of synthetic fertilizer use by 40%. Temple reduced FY 2010 GHG emissions from 230,567 MTeCO 2 to 227,511 MTeCO 2 (a 3,056 MTeCO 2 reduction) through offsets generated by the following on-campus activities: Composting (37 tons at Ambler campus); University computer reuse and recycling (4,556 units).

5 ATTACHMENT A: Methodology Changes from the FY2009 Report INVENTORY TOOL The FY GHG inventory was conducted using version 6.1 of the CA-CP Campus Carbon Calculator and the FY 2009 inventory was conducted using version 6.4 of the calculator. The FY 2010 inventory was conducted using version 6.6 of the calculator. The most significant changes between version 6.6 and earlier versions of the calculator are the increase in emission multipliers for electricity and solid waste. Therefore, the total gross emissions for FY are higher using version 6.6 than what was previously reported to the ACUPCC. Total emissions for FY have been recalculated using version 6.6 and the updated values are reflected in the GHG Emissions Summary. SCOPE 1 EMISSIONS The CA-CP Campus Carbon Calculator input unit for the natural gas fleet is MMBtu. The FY 2006 through FY 2009 GHG inventory erroneously reported the natural gas fleet in gas gallon equivalent (GGE). These input values have been corrected and the updated emission values are reflected in the GHG Emissions Summary. The Office of Facilities Management provided corrected (increased) values for the FY 2009 gasoline and diesel fleet. An automated fleet management system was implemented in FY 2010 and the usage values for FY 2009 were audited using this new system. The emissions in the GHG Emissions Summary reflect the updated values for FY SCOPE 3 EMISSIONS Temple University conducted a transportation survey during spring The 2010 Temple University Transportation Survey was used to populate the student, faculty and staff commuting portion of the CA-CP Campus Carbon Calculator for FY 2010 GHG inventory. Previous inventories used data from Temple s 2007 Transportation Survey. The 2010 survey is expected to reflect a more accurate picture of Temple commuting habits because it includes freshman, a population subset that was excluded in the 2007 survey. Paper purchasing was included in FY 2008 GHG inventory, but was excluded from the FY 2009 inventory because it is not representative of all university purchasing. Paper purchasing has been removed from the GHG inventory and the GHG Emissions Summary reflects the change in FY 2008 for scope 3 emissions. FY2010 GHG Inventory Update 5
