Has the institution conducted a GHG emissions inventory that includes all Scope 1 and 2 emissions? :
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 | All |
Purchased goods and services | Some |
Capital goods | None |
Waste generated in operations | All |
Fuel- and energy-related activities not included in Scope 1 or Scope 2 | All |
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:
To assemble and then analyze campus data related to GHG emissions, we used an online tool developed by the University of New Hampshire’s Sustainability Institute. The tool, known as the Sustainability Indicator Management and Analysis Platform (SIMAP), was developed over a period of nearly two decades and was preceded by the “gold standard of carbon calculators” known as the Clean Air-Cool Planet “Campus Carbon Calculator” (UNH, 2015).
SIMAP is comprised of three sections, referred to as “Scopes”. Scope 1 is defined as, “Direct emissions from sources that are owned and/or controlled by your institution”; Scope 2 is defined as, “Indirect emissions from sources that are neither owned nor operated by your institution but whose products are directly linked to on-campus energy consumption”; and Scope 3 is defined as, “Other emissions attributed to your institution, deemed ‘optional’ emissions by corporate inventories. This includes emissions from sources that are neither owned nor operated by your institution but are either directly financed or are otherwise linked to the campus via influence or encouragement” (UNH, 2020).
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?:
A brief description of the internal and/or external verification process:
The inventory document was independently reviewed by Facilities and Contracting officers at the college. Data collection and analysis was done by faculty in the Center for Sustainability.
Documentation to support the internal and/or external verification process:

A brief description of the institution’s GHG emissions reduction initiatives, including efforts made during the previous three years:
1. Principia continues its commitment to sourcing 100% power (electric)
2. Old (30-45 yr) boilers and air-cooled chillers have been replaced with a constant volume piping/ pumping system that relies on two water-cooled chillers and two condensing boilers. All pumps are variable flow controlled by VFD. The new system is designed to operate using 140°F or below heating water temperature (vs. the old 180°F) to take full advantage of the condensing boilers.
3. RCx completed on the largest campus building (Crafton Athletic Center) in 2019, RFP currently out for an RCx on the Science Center - the aim is to ensure our building emissions are as low as possible.
4. An RFP has been released for a comprehensive Energy Management Plan for the college.
