"---" 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 All
Commuting All
Purchased goods and services Some
Capital goods None
Waste generated in operations Some
Fuel- and energy-related activities not included in Scope 1 or Scope 2 Some
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:

SIMAP calculators were used to find data for OP-1. See the attached CSV file.
Commuting emissions were calculated with the transportation survey found in OP-15.
Business travel emissions:
Purchased goods and services: comes from paper and food purchasing. Information on paper can be found in OP-14 and the attached SIMAP csv file. Food purchasing can be found in OP-7.


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?:
Yes

A brief description of the internal and/or external verification process:

Student interns collect the data and are overseen by physical plant personnel and the STARS liaison. The results are validated internally by Environmental and Energy Sustainability Committee (EESC), which approves the data each year.


Documentation to support 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 9,723.08 Metric Tons of CO2 Equivalent 10,290 Metric Tons of CO2 Equivalent
Gross Scope 1 GHG emissions from other sources 422.89 Metric Tons of CO2 Equivalent 397 Metric Tons of CO2 Equivalent
Gross Scope 2 GHG emissions from purchased electricity 12,948.80 Metric Tons of CO2 Equivalent 16,104 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 23,094.77 Metric Tons of CO2 Equivalent 26,791 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 July 1, 2017 June 30, 2018
Baseline Year Jan. 1, 2009 Dec. 31, 2009

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 year was selected because it is after major renovations and building construction. The baseline year is recent enough to capture reliable data from the past and assess progress on sustainability efforts.


Figures needed to determine total carbon offsets:
Performance Year Baseline Year
Third-party verified carbon offsets purchased (exclude purchased RECs/GOs) 0 Metric Tons of CO2 Equivalent 0 Metric Tons of CO2 Equivalent
Institution-catalyzed carbon offsets generated 0 Metric Tons of CO2 Equivalent 0 Metric Tons of CO2 Equivalent
Carbon sequestration due to land that the institution manages specifically for sequestration 2,425 Metric Tons of CO2 Equivalent 2,425 Metric Tons of CO2 Equivalent
Carbon storage from on-site composting 19.83 Metric Tons of CO2 Equivalent 0 Metric Tons of CO2 Equivalent
Carbon offsets included above for which the emissions reductions have been sold or transferred by the institution 0 Metric Tons of CO2 Equivalent 0 Metric Tons of CO2 Equivalent
Net carbon offsets 2,444.83 Metric Tons of CO2 Equivalent 2,425 Metric Tons of CO2 Equivalent

A brief description of the offsets in each category reported above, including vendor, project source, verification program and contract timeframes (as applicable):

Sequestration is from the Dave Warners/Jack Phillips report in 2015 and attached at the end of this credit ("Carbon Budget Overview Summary").
The carbon storage from on-site composting comes from the SIMAP data sheet under "waste generated in operations" - data from Henry Kingma.

Additional documentation to support the submission:

Scope 3 Emissions can be found on the CSV file attached above from SIMAP. Commuting data comes from a transportation survey conducted with students, staff, and faculty. That survey is mentioned and attached in OP-15. (1.22.19 JW)
Paper purchasing only includes purchases through printing services, which accounts for around 1/2 of total paper purchased. All other departments purchase their own paper separately. (NL 1/22/19)
Purchased goods and services includes food. (JW 1.25.19)

Data revision April 26, 2019 in response to reviewers.
(1) Unmark any pursuit of "other categories" in the Scope 3 GHG Inventory.
(2) Changed the GHG Inventory to include details about distribution and transmission losses from purchased electricity. (NL 4.26.2019)
