"---" indicates that no data was submitted for this field

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 Some
Commuting Some
Purchased goods and services Some
Capital goods Some
Waste generated in operations Some
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:

The inventory was completed using the University of New Hampshire Campus Carbon Calculator. Commuting estimates were made based on a 2014 survey and home zip codes. Air travel was a partial record of the the air travel that could be tracked on a purchasing card, while student air travel was a complete record of study-abroad travel. We were unable to track other subsidized transit. Total incinerated waste was from a 2016 campus waste audit. Water entering sewer system was from our water bill minus a Facilities document tracking all water used that doesn't enter the sewer system. Paper was tracked by admissions and purchasing.


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?:
No

A brief description of 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 1 and Scope 2 GHG emissions:
Performance Year Baseline Year
Gross Scope 1 GHG emissions from stationary combustion 4,755.60 Metric Tons of CO2 Equivalent 5,212.70 Metric Tons of CO2 Equivalent
Gross Scope 1 GHG emissions from other sources 1,306 Metric Tons of CO2 Equivalent 305.70 Metric Tons of CO2 Equivalent
Gross Scope 2 GHG emissions from purchased electricity 6,749.60 Metric Tons of CO2 Equivalent 6,689.20 Metric Tons of CO2 Equivalent
Gross Scope 2 GHG emissions from other sources 0 Metric Tons of CO2 Equivalent 0 Metric Tons of CO2 Equivalent
Total 12,811.20 Metric Tons of CO2 Equivalent 12,207.60 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, 2015 Dec. 31, 2015
Baseline Year Jan. 1, 2010 Dec. 31, 2010

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):

The baseline GHG emissions report was published in March 2012 and was used in the College's last STARS report, using data gathered between 2005-2010. This is the last time that the College has conducted a complete GHG inventory.

Additional documentation to support the submission:

For Scope 3 GHG emissions from business travel, performance year (MtCO2e), the 282.7 tons is a minimum, not an estimate. We suspect that the minimum is substantially greater than the amount entered.

For "Waste generated in operations", the NH calculator calculated -27.4 MtCO2e. This is by the NH calculator because its burned for electricity. We entered "0" because we think it is technically wrong, since it is still putting carbon in the air and since the STARS program doesn't calculate negatives. We burn 685 tons of waste.

In Part 2, weighted campus users, specifically full time equivalent student enrollment and full time equivalent of employees, and number of students resident on site was reported for the 2015 school year when the GHG emissions report was conducted. These numbers do not match with the numbers in the same fields in IC-3, since those were from the 2016 school year.

In Part 3, gross floor area of building space, performance year was calculated for the GHG report that was reported in 2015. This does not match up with the total gross floor space reported in IC-2, since those numbers were from 2016.
