Has the institution conducted a GHG emissions inventory that includes all Scope 1 and 2 emissions? :
Yes

Does the institution’s GHG emissions inventory include all, some or none of its Scope 3 GHG emissions from the following categories?:
All, Some, or None
Business travel None
Commuting None
Purchased goods and services None
Capital goods None
Waste generated in operations None
Fuel- and energy-related activities not included in Scope 1 or Scope 2 None
Other categories None

A copy of the most recent GHG emissions inventory:
A brief description of the methodology and/or tool used to complete the GHG emissions inventory, including how the institution accounted for each category of Scope 3 emissions reported above:

We use the General Reporting Protocol for the Voluntary Reporting Program that is put out by The Climate Registry.


Has the GHG emissions inventory been validated internally by personnel who are independent of the GHG accounting and reporting process and/or verified by an independent, external third party?:
Yes

A brief description of the internal and/or external verification process:

Once the GHG emissions inventory is completed by Energy Management, it is submitted to the Director of Utilities and Energy Management for verification.


Documentation to support the internal and/or external verification process:
---

Does the institution wish to pursue Part 2 and Part 3 of this credit? (reductions in Scope 1 and Scope 2 GHG emissions):
Yes

Gross Scope 2 GHG emissions from other sources 0 Metric Tons of CO2 Equivalent 0 Metric Tons of CO2 Equivalent
Total 82,474.18 Metric Tons of CO2 Equivalent 165,547.50 Metric Tons of CO2 Equivalent

Start and end dates of the performance year and baseline year (or three-year periods):
Start Date End Date
Performance Year Jan. 1, 2017 Dec. 31, 2017
Baseline Year Jan. 1, 2006 Dec. 31, 2006

A brief description of when and why the GHG emissions baseline was adopted (e.g. in sustainability plans and policies or in the context of other reporting obligations):

CY 2006 was the first year that OSU completed a GHG emission inventory. It also coincides with the base-year for the OSU Energy Management Program.

Emissions reductions attributable to Renewable Energy Certificate (REC) or Guarantee of Origin (GO) purchases:
Performance Year Baseline Year
Emissions reductions attributable to REC/GO purchases 0 Metric Tons of CO2 Equivalent 0 Metric Tons of CO2 Equivalent

A brief description of the purchased RECs/GOs including vendor, project source and verification program:

Renewable Energy Credits are sold by Oklahoma Gas and Electric Company (OG&E) to Oklahoma State University, pursuant to the Amended and Restated Agreement for Electric Service between OG&E and OSU, dated November 9, 2011.

OG&E certifies that RECs 1) were not sold, marketed or otherwise claimed by any third party, 2) the RECs, and the generated electricity was not used by OG&E to meet any federal, state, or local renewable energy requirements, renewable energy procurement, renewable portfolio standard, or other renewable energy mandate; and 3) the electrical energy generated with these RECs was not sold or separately marketed as renewable energy by OG&E. The Blackwell Wind, LLC. aka "Cowboy Wind Farm" generated all of the RECs sold to OSU.

A brief description of the institution’s GHG emissions reduction initiatives, including efforts made during the previous three years:

OSU's carbon footprint, which we have been tracking since 2006, has been greatly reduced by our purchase of wind power RECs that provide approximately 72% of the campus' electricity. Facilities Management recently instituted a No-Idle Policy and the Department of Parking & Transit has many measures in place to reduce pollution included CNG powered buses, carpool and bike programs. These initiatives, along with an aggressive energy conservation policy and the OSU Energy Management Program have reduced overall energy usage and emissions across campus. The Cowboy Wind Farm supplies approximately 72% of OSU Stillwater's electricity annually and that has been the largest contribution to OSU's Greenhouse Gas emissions reduction since OSU's baseline year.
