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

On-site composting has been a COA tradition since the 1970s. Currently, COA is composting on campus all waste from our composting toilets. Buildings & Grounds and “Discarded Resources” work-study students track all on-campus composting. They keep a record of every toilet harvest, and calculate the total tonnage for the reporting period.


Adjusted net Scope 1 and Scope 2 GHG emissions:
Performance year Baseline year
Adjusted net GHG emissions 702.26 Metric Tons of CO2 Equivalent 1,082 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, 2020 July 1, 2004
End date June 30, 2021 June 30, 2005

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

In spring 2006, COA began using the Clean Air-Cool Planet Carbon Calculator, so 2005 was the most recent year for which we could collect accurate data to enter into the calculator.

Adjusted net Scope 1 and 2 GHG emissions per weighted campus user:
Performance year Baseline year
Adjusted net Scope 1 and 2 GHG emissions per weighted campus user 1.87 Metric Tons of CO2 Equivalent 3.53 Metric Tons of CO2 Equivalent

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

College of the Atlantic is currently undertaking a project to insulate and air seal all existing buildings, and to retrofit them with high-efficiency air source heat pumps to reduce reliance on stationary fossil fuel sources. Prior, the College conducted an energy audit of every building on campus. A working group of students, staff and faculty reviewed the audits, and presented a recommendation to COA's Board of Trustees proposing a three-phase implementation plan.
Students have installed over 60 solar panels as part of academic courses and are involved in every aspect of our energy framework through these courses, work-study positions, independent studies and senior projects.
The College continues to contract all of its electricity from midwest wind power sources while paying for the associated RECs in real time. We are switching out CFL bulbs and fluorescent tube lighting for newer, more energy efficient LED lights using both bulb and modular tube LED types. A switch to modular LEDs in the college's dining hall kitchen was completed in May 2014.
Through practical, hands-on energy courses students are working on energy reduction issues on campus. In the Physics and Math of Sustainable Energy course, offered each year, student-group projects have included a wide number of emissions reduction initiatives, including: reducing water pumping for irrigation at one of the college's farms; assessing heating needs and alternative heating solutions for campus; and investigating heat pump technology to take heat out of the campus kitchen and use it to heat domestic hot-water.
