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

Wentworth's GHG emissions inventory was developed in accordance with the WRI / WBCSD "The GHG Protocol Corporate Accounting and Reporting Standard" using the Clean Air Cool Planet Campus Carbon Calculator, version 9.0.

Note that for scope 3, waste total tonnage is tracked in the Carbon Calculator, however the Calculator shows waste emissions as a negative number due to off-site treatment (methane capture & energy production). Wentworth has zeroed out this "carbon sink" in an effort to retain a more conservative estimate of campus GHG emissions.


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:
---

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 4109 Metric Tons of CO2 Equivalent 3794 Metric Tons of CO2 Equivalent
Gross Scope 1 GHG emissions from other sources 356.60 Metric Tons of CO2 Equivalent 169 Metric Tons of CO2 Equivalent
Gross Scope 2 GHG emissions from purchased electricity 3352.90 Metric Tons of CO2 Equivalent 2702 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 7818.50 Metric Tons of CO2 Equivalent 6665 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, 2016 Dec. 31, 2016
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 GHG emissions baseline was adopted during Wentworth's climate action planning process, as part of meeting the requirements of the Carbon Commitment. The baseline was selected because it was the first year which had the most complete and accurate accounting of campus GHG emissions.

A brief description of the institution’s GHG emissions reduction initiatives, including efforts made during the previous three years:

GHG reduction efforts over the last few years included: LED lighting retrofits, HVAC equipment and controls upgrades, combined heat and power plant repairs and upgrades (started in 2018, due for completion in early 2019), steam trap maintenance program, and LEED Silver (or higher) equivalent green building design & construction strategies including high efficiency HVAC equipment, insulation, controls, etc. The new CEIS building is the latest example (under construction during 2018) which is predicted to save 37% on energy costs compared to baseline construction, and hosts the first solar PV array on campus.
