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 None
Commuting None
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 Some

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:

We have consistently used the Clean Air Cool Planet spreadsheet with data going back to 2001. For FY 2017, we switched to SIMAP, CACP's successor, and populated the data going back 5 years.


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:

Internal data is gathered primarily from Facilities Management Services records which are verified against university financial records. Partial commuter and travel records are gathered from Parking and Transportation Dept and extrapolated based on known ratios from the university's contract travel agent. The GHG inventory data was compiled by the University Engineer and Environmental Coordinator and was reviewed by members of the Green Practices Committee Working Group, 2 Faculty members, and the AVP of Facilities Management and Campus Services and the Director of FMCS Operations. We had a discussion about our data collection methodology, past and present and the committee recommended how to share our GHG inventory data with the public.

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

Althought tThe most significant Scope 1 reduction occurred in 2009 when the Bellefield Boiler Plant, partially owned by CMU, converted from coal and natural gas operation to 100% natural gas firing, CMU continues to pursue deeper GHG emissions reductions. Starting in 2011, CMU has purchased RECs to offset 100% of our electricity purchases. In both 2017 and 2018, CMU purchased RECs from the Prairie Breeze wind energy farm in Nebraska where renewable electricity generation replaces sources with the highest CO2 emissions in the nation. In addition to the ongoing 100% offset with RECs, beginning in October 2017, we also entered into a unique agreement to purchase 100% of our electricity supply (kWh equivalent) from an Illinois wind farm in our own grid territory (PJM). For this, we have a 2-year agreement with extensions available through 2021.

Carnegie Mellon University's GHG emissions inventory was first initiated by an undergraduate research study in spring of 2007 in cooperation with few graduate students and faculty members using the Clean Air-Cool Planet calculator. The student project was expanded, corrected, and refined by the Green Practices intern Andrew Ko, university engineer, Martin Altschul and the university environmental coordinator, Barbara Kviz. The University's GHG emission inventory was calculated from 1995-present, to also reflect the pre and post 2006 regional EPA emissions factor reclassification. EPA eGrid pre-2006 subregion was corrected from prior submissions. Per EPA documentation Duquesne Light and Pittsburgh were considered to be in ECAR Ohio Valley. For our Scope 3 transportation accounting we have relied on very small sample sizes historically. For this submission we have decided not to include those emissions, because we are uncertain of their accuracy. We continue to study the problem and hope to report on scope 3 emissions on future GHG reports.

It should be noted that the emission numbers reflect the University's growth and rebuilding efforts since year 2005.
