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 | Some |
| Purchased goods and services | None |
| Capital goods | None |
| Waste generated in operations | All |
| 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:
Bates College early carbon inventories were completed both in-house and by outside contractors, often using different methodologies and carbon calculators. Our most recent outside contractor, the Stone House Group, completed an inventory in 2009, which is also included at the bottom of the page. Early years used the Clean Air Cool Planet emissions calculator.
Our most recent 2017 carbon inventory has been completed in-house, working with the students, faculty, and the facilities department. We have taken energy usage data and standardized the methodology from years past. Our emissions factors are from the EPA's GHG Emissions Hub. Our scope 3 emissions were collected for commuting by creating a GIS map of staff and faculty homes (anonymously) and taking an average of miles commuted, days commuted, and vehicle mpg. We also keep track of our waste stream tonnage, again using EPA emission factors, using our bills for our tipping fees. Please note that years 2018-2020 are projected estimates.
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:
As stated above, we have a mix of inventories, some validated by external consultants, for example, the Stone House Group, and others performed in-house. For our most recent carbon inventory, we had the Committee for Environmental Responsibility, the Director of Facilities, and the Chief Financial Officer review the emissions inventory. These groups are independent from the carbon reporting, which takes place under the Sustainability Office.

Does the institution wish to pursue Part 2 and Part 3 of this credit? (reductions in Scope 1 and Scope 2 GHG emissions):

| Gross Scope 2 GHG emissions from other sources | 0 Metric tons of CO2 equivalent | 0 Metric tons of CO2 equivalent |
| Total | 7,494.70 Metric tons of CO2 equivalent | 13,496 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, 2016 | July 1, 2017 |
| Baseline Year | July 1, 2000 | July 1, 2001 |
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):
Our Energy Task Force, as well as our Committee for Environmental Responsibility, made up of Facilities and Faculty members, sought to begin the process of documenting our carbon emissions in 2000. The initial motivation for this came from the newly-hired part-time Environmental Coordinator, and from the Environmental Studies department. By 2001, they had put the structures in place to start collecting energy data for the first GHG inventory. Our Environmental Coordinator also believed that it would be a good project to involve students in real-world data analysis, and so part of the initial motivation was student-driven.
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 | 0 Metric tons of CO2 equivalent | 0 Metric tons of CO2 equivalent |
| Carbon storage from on-site composting | 0 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 | 0 Metric tons of CO2 equivalent | 0 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):
We do not purchase carbon offsets.
Emissions reductions attributable to Renewable Energy Certificate (REC) or Guarantee of Origin (GO) purchases:
| Performance Year | Baseline Year | |
| Emissions reductions attributable to REC/GO purchases | 3,379 Metric tons of CO2 equivalent | 0 Metric tons of CO2 equivalent |
A brief description of the purchased RECs/GOs including vendor, project source and verification program:
We purchase our RECs for all our electricity from the energy supplier Constellation New Energy, enough to account for 100% of our electrical use. Their RECs come from 100% wind power. Constellation uses Green-e Energy for its verification program (from their website):
Green-e Energy is the nation's leading independent certification and verification program for renewable energy and companies that use renewable energy. Green-e Energy sets consumer protection and environmental standards for renewable electricity products. Green-e Energy standards address such issues as the environmental performance of the facility, the year in which the facility began operation, and the year in which the REC was generated. The Green-e Energy label certifies that the power is from an eligible renewable energy resource.

A brief description of the institution’s GHG emissions reduction initiatives, including efforts made during the previous three years:
This past heating season, we have begun burning a new biomass-based liquid fuel in our central steam plant. This fuel, known as Renewable Fuel Oil, has dramatically reduced our carbon emissions. It comes from a rapid pyrolysis process of waste sawdust - that is, the wood fibers are volatilized in the absence of oxygen, then condensed to form a liquid fuel. We were able to use our original central steam plant boilers to burn this fuel, which helped enormously with the cost of adoption of this new fuel. See Innovation Credit for more info.
About a third of our reductions come from energy efficiency measures. Installing VFD's and heat recovery systems, as well as upgrading sections of our steam line, and insulating our largest buildings have helped us see a large EUI reduction. We have recently installed a more robust building controls and monitoring system, which has allowed us to establish night time and holiday setbacks.
We also purchase 100% green power for all our electricity. We have begun burning a B20 biodiesel blend in our smaller houses. We are currently on track to meet our carbon neutrality goal of 2020.

Data source(s) and notes about the submission:
Our early climate inventories use Clean Air Cool Planet emissions factors, as well as national electric emissions factors, rather than the actual regional grid mix, which is substantially different.
In our most recent inventory, we have used emissions factors from the EPA's GHG Emissions Hub. We have used the EPA's electricity emission factors from our region, calculating everything back to 2001, which is our baseline. For this reason, the Stone House inventory has somewhat different emissions numbers. We have standardized all emissions factors and methodologies, so that a fair comparison can be made from year to year.
