"---" 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 Some
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 measure greenhouse gas emissions, Colby uses the Sustainability Indicator Management and Analysis Platform (SIMAP), designed by the University of New Hampshire, which is recommended by the American College and University Presidents’ Climate Commitment (ACUPCC) because it was designed specifically for college and university campuses.


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:

A student intern collected the data for the campus carbon inventory. The data was then reviewed by a number of people within the Facilities Department, including the Sustainability Director, the Director of Operations and Maintenance, the Director of Business and Administrative Services, and the Assistant Vice President for Facilities and Campus Planning.


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

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):

We are using FY2005 as a common baseline throughout this submission, as this was the year that the College began formally tracking data in all STARS reporting fields.

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

Colby is a carbon neutral campus, and thus is constantly considering its GHG emissions. Colby hosts an annual Dorm Electricity Competition to encourage students to cut back on their electricity use, and therefore the amount of greenhouse gases released due to energy production. The College has also been undergoing a utility retrofitting project which includes replacing lighting fixtures with LEDs, insulating the steam pipes, and developing the on-going commissioning program to ensure operational efficiency. Colby composts all of its landscaping debris on-campus, however this amount is not measured and all food waste is taken off-campus to a composting facility 50 miles from the College. Additionally, 100% of the steam from the biomass plant goes out to campus to heat and generate electricity.
