The OSU Climate Plan includes the following emissions categories:
It is within these categories that specific emissions targets have been set.
|2,404 t CO2e||2,507 t CO2e||2,410 t CO2e||2,299 t CO2e||2,150 t CO2e|
In FY08, emissions from ground transportation contributed almost 12,000 t CO2e. Emissions from student and employee commute, fleet, athletic bus travel, rental car mileage, and personal vehicle mileage used for business purposes are included in this category. Emissions from this category have increased by 13% since 2004, the oldest year with intact data. Some of this increase represents actual growth, while some is a result of improved data collection. Additionally, there are known sources that have not been captured in past inventories, athletics travel reimbursement for example, so actual emissions from this category may increase further.
||FY10 Progress||Estimated FY10 Reduction|
|1: Minimize climate impact of animal husbandry|
|2: Minimize climate impact of crop cultivation|
|3: Offset remaining emissions from agriculture|
For more detail, please see OSU Climate Plan pages 29-30.
|23,496 t CO2e||23,265 t CO2e||21,652 t CO2e||21,250 t CO2e||40,000 t C02e|
In FY08, air travel was the largest source of net emissions for OSU, contributing more than 35,000 t CO2e. Emissions from air travel have increased rapidly in the past years; the European Environmental Agency estimated that emissions from air travel increased 73% between 1990 and 2005. The growth in university‐related air travel and the lack of alternatives to air travel
make this a difficult source to mitigate. Because many university‐related activities occur at great distances from the main campus and because Oregon occupies a coastal – rather than central – location in the United States, air travel is expected remain a necessary transportation mode for a considerable number of faculty.
Even with these complicating factors, emissions from air travel can be reduced without drastically impacting the way OSU does business.
|Strategy||Implementation Period||FY10 Progress||Estimated FY10 Reduction|
|1: Encourage alternative transportation modes||FY11||N/A|
|2: Restrict air travel (or reimbursements) in certain cases|
|3: Encourage use of alternatives to travel (technologies such as teleconferencing, etc.)||FY11||Teleconferencing|
|4: Minimize climate impact of air travel|
|5: Offset remaining emissions from air travel|
For more detail, please see OSU Climate Plan pages 24-26.
|80,503 t CO2e||31,074 t CO2e||28,543 t CO2e||42,854 t CO2e||500 t CO2e|
In FY08, gross emissions from electricity generation and distribution was the largest source of emissions for OSU, contributing over 85,000 t CO2e. However, due to the large purchase of renewable energy certificates (RECs) funded by student‐endorsed
renewable energy fee, net emissions for electricity amounted to just over 32,000 t CO2e. Electricity use has grown by 19% since 1998, the oldest year with intact data. Emissions from electricity are expected to decrease by 50% over the coming years as a result of the Energy Center.

The OSU Sustainability Office measures OSU's greenhouse gas emissions annually through a very detailed inventory process and issues a public report that illustrates emissions by emissions source. FY12 emissions from major emissions sources are shown in Figure 1.
A central tenet of the American College and University President's Climate Commitment (ACUPCC) is the "pursuit of climate neutrality". Climate neutrality is defined as having no net greenhouse gas (GHG) emissions. This is to be achieved by minimizing emissions as much as possible, and using carbon offsets or other measures to mitigate the remaining emissions. This applies to all Scope 1 and 2 emissions (defined below), as well as those Scope 3 emissions from commuting and from air travel paid for by or through the institution.
Identifying scope and boundaries issues is a critical step in emissions reporting. In an effort to measure all emissions resulting from OSU activity, the boundaries were drawn to be fairly broad: any emissions from an entity over which OSU has financial and/or operational control were included.
Some emissions sources are intentionally omitted due to unavailable data, poor data quality or the inability to properly calculate emissions, mainly as a result of uncertain emissions calculation methodology. Omitted sources include
Past, current and future inventories may not be absolutely comparable for all source categories. Fiscal year greenhouse gas emissions reports are static; once submitted, data are not altered. Yet in the most current annual report, past year emissions totals are updated to present the highest-quality data using the latest calculation methods. Because of this, comparing emissions from emission sources based on annually reported values may not align with comparative values described in a report. For instance, the FY09 report notes a 10.6% decrease in air travel emissions from FY08 to FY09. Using emissions data presented in the FY08 report, the decrease would be 41.0%. This difference is due to a data reporting miscommunication in the FY08 report. For the most accurate year-to-year comparisons, reference the most recent annual report. Updated net emissions from FYs '07, '08, '09. and '10 are shown in Figure 2.
An integral piece of measuring emissions is comparing data with peer institutions. All ACUPCC signatories are required to submit emissions reports to the ACUPCC reporting website. Figure 3 shows inter-institutional emissions comparisons with peer institutions.
Emissions by source are shown in Figure 4.

In January 2012, the OSU Sustainability Office completed the Fiscal Year 2011 Greenhouse Gas Inventory report, similar to the most recent reports below.

In March 2011, the OSU Sustainability Office completed the Fiscal Year 2010 Greenhouse Gas Inventory report. Very similar in scope and boundaries to the FY09 report, this latest report includes for the first time emissions from the Energy Center, non-contract car rentals, non-TRES reimbursed travel, and more.

In March 2010, the OSU Sustainability Office completed the Fiscal Year 2009 Greenhouse Gas Inventory report. Very similar in scope and boundaries to the FY08 report, this latest report implements best practices in greenhouse gas measurement and reporting. It is the most accurate and comprehensive performed to date.

In March 2009, the OSU Sustainability Office completed the Fiscal Year 2008 Greenhouse Gas Inventory report. The Sustainability Office refined and implemented major changes relative to FY07 in the FY08 scope and boundaries, and updated processes based on internationally-recognized updates in greenhouse gas reporting.

In the summer of 2009, the Oregon University System contracted with Good Company to provide an analysis of the embodied emissions (emissions produced during the lifecycle of a produce) of goods and services purchased by the seven OUS institutions. These emissions, which include emissions from construction, food, paper, equipment and furniture, were calculated based on expenditures incurred during FY08 and totaled nearly 85,000 t CO2e for OSU.

In June 2008, the Sustainability Office completed the greenhouse gas inventory report for FY07. This was the first comprehensive greenhouse gas inventory completed by OSU.
The FY07 report details emissions sources and their relative contribution to OSU's emissions profile, contains an apples-to-apples comparison with the CY04 report and also elaborates about methodology and the new expanded scope that, in its time, made the FY07 inventory the most accurate produced for OSU.

In 2006 and 2007, the Oregon University System hired Good Company to create the first ever greenhouse gas inventory for the seven OUS campuses. As part of that work, Good Company created profiles for each institution based on available data, which varied from campus to campus.

In 2009, the Oregon University System hired Good Company to estimate 1990 emissions resulting from buildings for all seven OUS campuses. This emissions estimate was calculated using campus building square footage and a study on building energy use for the western United States.
