GHG Report for Community College of Denver
Submitted on February 14, 2011; last updated on May 17, 2012
Summary StatisticsMaking fair comparisons between higher education institutions is always challenging due to the rich diversity of higher education. The unverified nature of the information in this database and unavailability of unbiased normalization metrics means such comparisons are even more difficult. Users should therefore approach direct institution to institution comparisons with caution and recognize that all comparisons between institutions are inherently biased.
|Total||Per Full-Time Enrollment||Per 1000 Square Feet||% Offset|
|Gross emissions (Scopes 1 + 2)||5,213 metric tons of CO2e||0.8 metric tons of CO2e||17.2 metric tons of CO2e||69%|
|Gross emissions (Scopes 1 + 2 + 3)||7,757 metric tons of CO2e||1.2 metric tons of CO2e||25.6 metric tons of CO2e||46%|
|Net emissions||4,175 metric tons of CO2e||0.6 metric tons of CO2e||13.8 metric tons of CO2e||N/A|
Emissions Inventory Methodology and Boundaries
|Start date of the 12-month period covered in this report||July 1, 2009|
|Consolidation methodology used to determine organizational boundaries||Equity share approach|
If any institution-owned, leased, or operated buildings or other holdings that should fall within the organizational boundaries are omitted, briefly explain why.
The Auraria Campus is shared by three institutions of higher education - Community College of Denver (CCD), Metropolitan State College of Denver (Metro State), and the University of Colorado Denver Downtown Campus (UC Denver). The Auraria Campus is operated by a fourth organization called the Auraria Higher Education Center (AHEC). Given that a fourth entity owns and maintains the buildings, it made more sense to study the boundary related to the Auraria Campus, under AHEC's financial control.
|Emissions calculation tool used||Custom tool|
Please describe why this tool was selected.
This method was selected since it was suggested by the ACUPCC and allowed for accounting of both in boundary and out of boundary activities.
Please describe the source(s) of the emissions coefficients used.
The emissions coefficients used are listed in Section 5 of our report and included - ICLEI, Xcel Energy (local energy provider), GREET, EPA WARM/DRC, EIA, WRI, EPA PCA, GWI, EIO-LCA and Denver Water (our local provider of water).
|Which version of IPCC's list of global warming potentials did you use?||Third Assessment Report|
|Who primarily conducted this emissions inventory?||Sustainability office staff|
Please describe the process of conducting the inventory.
The AHEC Sustainability officer worked directly with AHEC's Planning Department and Facilities Management to gather data related to the emissions of the campus. These data were analyzed and the report was prepared. A draft was reviewed by those involved in gathering the data to make sure the conclusions made sense.
Please describe any emissions sources that were classified as de minimis and explain how a determination of the significance of these emissions was made.
It was decided by the respective CFOs that off-campus leased space used by CCD and Metro State would not be included in the 2010 greenhouse gas (GHG) inventory, the 2009 climate action plan (CAP), or this report due to complications arising from the control of energy use and payments on those facilities. The Auraria Campus Sustainability Committee and the AHEC Sustainability officer recommend that staff from the respective higher education institutions work to include these in future ACUPCC reports.
Please describe any data limitations related to this submission and any major assumptions made in response to these limitations.
