A brief description of when and why the GHG emissions baseline was adopted:

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.

A brief description of the institution’s GHG emissions reduction initiatives:

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.
