Part 1 

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:
Operational control approach Custom tool Conversion factors were taken from the World Resources Institute (WRI) calculation tool. Conversion factors not from the World Resources Institute are from government agencies such as the California Public Utilities Commission and the US Environmental Protection Agency. CO2 equivalents were calculated using Global Warming Potential figures specified by the WRI.

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

Part 2 

Gross Scope 1 and Scope 2 GHG emissions:
Performance Year Baseline Year
Gross Scope 1 GHG emissions from stationary combustion 2,100.25 Metric tons of CO2 equivalent 3,196 Metric tons of CO2 equivalent
Gross Scope 1 GHG emissions from other sources 168.05 Metric tons of CO2 equivalent 88 Metric tons of CO2 equivalent
Gross Scope 2 GHG emissions from purchased electricity 1,021.14 Metric tons of CO2 equivalent 1,521 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 3,289.44 Metric tons of CO2 equivalent 4,805 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, 2015 June 30, 2016
Baseline Year July 1, 2007 June 30, 2008

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 ACUPCC directive fell under the auspices of the Mills College Sustainability Committee, formed in 2007 and made up of students, faculty and administration. One of the students on the committee took on the GHG inventory as her senior thesis. Two staff members, the recycling manager and architectural assistant, assisted in data collection and advised on the process. Access to utility, waste, air travel, and commuting data farther back than FY2008 was limited.

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

If total performance year carbon offsets are greater than zero, provide:

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

The reporting fields in the table below are reserved for institutions that have NOT already accounted for renewable energy purchases (including RECs and GOs) in their Scope 2 GHG emissions calculations. Other institutions - including all SIMAP users - should report zero ('0') to avoid double-counting. 

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 0 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:
---
