3 GHG Protocol Scope 1 Direct emissions from sources that are owned and/or controlled by your institution. This includes combustion of fossil fuels in college-owned facilities or vehicles, fugitive emissions from refrigeration, and emissions from on-campus agriculture or livestock husbandry. Your institution has complete control over these emissions, and they are noone else s responsibility. Examples of Scope 1 emissions include: On-Campus Stationary Sources Emissions from all on-campus fuel combustion, excluding vehicle fuels Direct Transportation Sources Emissions from all fuel used in the institution s fleet (the vehicles it owns) Refrigeration and other Chemicals Fugitive emissions from refrigerants and other sources Agriculture N 2 O emissions from fertilizer use and CH 4 emissions from animals (cattle, horses, etc.)

4 GHG Protocol Scope 2 Indirect emissions from sources that are neither owned nor operated by your institution but whose products are directly linked to on-campus energy consumption. Although your institution is not directly responsible for these emissions, it is strongly implicated. These emissions come from converting energy sources that release greenhouse gas emissions when used (fossil fuels) to energy sources that do not (electricity, steam, or chilled water). Although your institution did not burn the coal to make the electricity you use, someone had to, and although the electricity producer emitted the gasses, they did not use any of the energy produced. Examples of Scope 2 emissions include: Purchased Electricity Emissions from the production of any electricity the institution purchases Purchased Steam Emissions from the production of steam purchased from off-campus Purchased Chilled Water Emissions from the production of chilled water purchased from off-campus

5 GHG Protocol Scope 3 Other emissions attributed to your institution, deemed optional emissions by corporate inventories. This includes emissions from sources that are neither owned nor operated by your institution but are either directly financed (i.e. commercial air travel paid for by the institution) or are otherwise linked to the campus via influence or encouragement (i.e. air travel for study abroad programs, regular faculty, staff, and student commuting). Many Scope 3 emissions are considered upstream like the emissions associated with making and transporting plastic silverware.

6 GHG Protocol Scope 3 To prevent institutions from accounting for too many upstream emissions, most campuses define distinct financial or control boundaries to distinguish which Scope 3 emissions they are indeed responsible for, including: Solid Waste Emissions from managing the institution s waste (incineration, landfilling, etc.) Directly Financed Outsourced Transportation Emissions from travel that is paid for by the institution, but does not occur in fleet vehicles (business trips in commercial aircraft, staff travel in personal vehicles where mileage is reimbursed, etc.) Commuting Emissions from regular commuting by faculty, staff, or students (does NOTinclude student travel to and from home over breaks) (note student commuting is generally considered to be under a greater degree of institutional control than staff/faculty commuting) Study Abroad Air Travel Emissions from students flying to their study abroad location Transportation and Distribution Losses from Purchased Energy Energy lost while transporting purchased electricity, steam, or chilled water to campus Upstream Emissions from Directly Financed Purchases Emissions associated with paper production, food production, fuel extraction, etc.

7 GHG Protocol Offsets - The University footprint is what it is, regardless of what happens outside of campus. However, universities may choose to use their financial control over outside entities in a way that creates a net reduction in worldwide carbon emissions that otherwise would not have occurred, one can justly declare that you have offset another entity s carbon. Usually, offset transactions are managed by firms that specialize in such complex transactions, but institutions can claim their own offsets if they oversee their own offcampus carbon reduction projects.

8 Reporting Protocol All Directly Financed or Significantly Encouraged Emissions, Plus Selected Upstream Emissions: This includes all of Scopes 1 and 2, plus any directly financed or encouraged Scope 3, and selected Scope 3 upstream emissions. For example, UH might choose to include in its inventory the Scope 3 upstream emissions from producing and transporting purchased paper. If the university then instituted a policy that reduced paper use, its emissions would be proportionately reduced. It is also possible to track selected Scope 3 upstream emissions but not include them in the institution s footprint.

9 Reporting Protocol The American College and University Presidents Climate Commitment (ACUPCC) protocol requires that signatories inventory all Scope 1 and 2 emissions and report Scope 3 emissions from commuting and directly financed air travel to the extent that data is available. Institutions are also encouraged to report any other Scope 3 emissions, especially those that are large or can be meaningfully influenced.

17 Scope 3: Input Data 2010 Commute - Student Population base was 38,752 students. Of this total 30,095 drove a car to school,1,337 rode the Metro and 4,234 commuted via carpooling (assume 2 per car gives 2,117 more cars driven). Individuals plus carpool gives 32,212 commuters. - Faculty / Staff population was assumed to be 6,153, of which 500 commuted via Metro. - Full time students commuted 4 days a week, part time students commuted 3 days, an average of 3.5 days a week for both, and faculty and staff commuted 5 days a week. Assumed that students commuted 16 weeks each fall and spring semester for a total of 32 commuting weeks per year, while faculty and staff commuted 50 weeks per year.
