A brief description of the carbon sinks, including vendor, project source, verification program and contract timeframes (as applicable):

The college provides space for four investor-owned solar arrays on campus (beginning in 2014), specifically: one ground mounted array on the Gellerstedt Soccer Field, and three rooftop arrays on the Office of Facilities building, Bullock Science Center, and West Campus Parking Deck. Though these arrays are housed on campus, we do not directly consume energy generated by these solar projects; the power is sold by the investors to Georgia Power for the utility's power supply and the total estimated power produced is enough for 31 average US homes. In the legal leasing agreement with the investors, Agnes Scott retained the environmental attributes for the arrays; therefore, the college can pursue offset reductions. Given that Georgia has no offset or REC registry, the college worked with Southface Energy Institute to peer review the process for assigning value to these offsets.


Adjusted net Scope 1 and Scope 2 GHG emissions:
Performance year Baseline year
Adjusted net GHG emissions 6,609.88 Metric Tons of CO2 Equivalent 11,015 Metric Tons of CO2 Equivalent

Start and end dates of the performance year and baseline year (or three-year periods):
Performance year Baseline year
Start date July 1, 2018 July 1, 2007
End date June 30, 2019 June 30, 2008

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

The baseline was adopted across STARS credits based on Agnes Scott's best historic data within recent years. This same baseline has been used across all STARS reports.

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

Agnes Scott College's approach to reducing GHG emissions revolves around buildings and transportation. Over the past several years the college has assessed and developed plans to address energy use in its buildings. Strategies that have been used include retrocommissioning and retrofits of building systems and equipment, adjustments to time of use, and energy behavior education and implementation. These efforts have been accelerated by the college's commitment to a Green Revolving Fund, for which we have raised over $1 million, and we have invested a total of $2 million, combining funds raised with utility savings revolved back to the fund, in energy and water efficiency projects. This investment will be paid back to the fund in 15-20 years. The next round of efficiency projects has begun and we are also renewing our fund raising efforts.

Agnes Scott has also supported alternative transportation options including biking, carpooling and public transit such as MARTA. Additionally, a no-idling policy was implemented to addressed localized GHG emissions from service and delivery vehicles.
