"---" indicates that no data was submitted for this field

Does the institution's GHG emissions inventory include all Scope 1 and Scope 2 GHG emissions?:
Yes

Does the institution's GHG emissions inventory include all Scope 3 GHG emissions from any of the following categories?:
Yes or No
Business travel Yes
Commuting No
Purchased goods and services No
Capital goods No
Fuel- and energy-related activities not included in Scope 1 or Scope 2 Yes
Waste generated in operations Yes

Does the institution's GHG emissions inventory include Scope 3 emissions from other categories?:
Yes

A brief description of the methodology and/or tool used to complete the GHG emissions inventory:

We have consistently used the Clean Air Cool Planet spreadsheet with data going back to 2001.


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:

Internal data is gathered primarily from Facilities Management Services records which are verified against university financial records. Partila commuter and travel records are gathered from Parking and Transportation Dept and extrapolated based on known ratios from the university's contract travel agent.


Scope 1 and Scope 2 GHG emissions::
Performance Year Baseline Year
Scope 1 GHG emissions from stationary combustion 29667.50 Metric Tons of CO2 Equivalent 35852.50 Metric Tons of CO2 Equivalent
Scope 1 GHG emissions from other sources 1229.80 Metric Tons of CO2 Equivalent 713 Metric Tons of CO2 Equivalent
Scope 2 GHG emissions from purchased electricity 66463.20 Metric Tons of CO2 Equivalent 61808.80 Metric Tons of CO2 Equivalent
Scope 2 GHG emissions from other sources 0 Metric Tons of CO2 Equivalent 0 Metric Tons of CO2 Equivalent

Figures needed to determine total carbon offsets::
Performance Year Baseline Year
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
Third-party verified carbon offsets purchased 66460 Metric Tons of CO2 Equivalent 3715.70 Metric Tons of CO2 Equivalent

A brief description of the institution-catalyzed carbon offsets program:

Carnegie Mellon University does not have local offsets program to offset its greenhouse gas emissions.


A brief description of the carbon sequestration program and reporting protocol used:

No Carbon sequestration program


A brief description of the composting and carbon storage program:

Composting is done off-campus by a 3rd party and does not qualify.


A brief description of the purchased carbon offsets, including third party verifier(s) and contract timeframes:

Green-E RECs are purchased annually in the amount of estimated electical use for that year.

Number of residential students 3935 3744
Number of residential employees 0 0
Number of in-patient hospital beds 0 0
Full-time equivalent enrollment 11263.60 8803.40
Full-time equivalent of employees 4816 3978.30
Full-time equivalent of distance education students 132.60 106.50

Start and end dates of the performance year and baseline year (or three-year periods):
Start Date End Date
Performance Year July 1, 2012 June 30, 2013
Baseline Year July 1, 2004 June 30, 2005

A brief description of when and why the GHG emissions baseline was adopted:

Baseline of FY 2005 was adopted after a CACP analysis was done for that year.

Other categories (please specify below) 0 Metric Tons of CO2 Equivalent

A brief description of the sources included in Scope 3 GHG emissions from "other categories":

Note that data for commuting only shows emissions for Bus and Rail commuting. No data is available for automobile commuting.

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

Starting in 2011, CMU has purchased RECs to offset 100% of our electricity purchases. The most significant Scope 1 reduction occurred in 2009 when the Bellefield Boiler Plant, partially owned by CMU, convwerted from coal and natural gas operation to 100% natural gas firing.


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.

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