GHG Report for Arizona State University
Submitted on December 30, 2008; last updated on May 16, 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)||228,278 metric tons of CO2e||3.8 metric tons of CO2e||18.4 metric tons of CO2e||0%|
|Gross emissions (Scopes 1 + 2 + 3)||293,270 metric tons of CO2e||4.8 metric tons of CO2e||23.7 metric tons of CO2e||0%|
|Net emissions||293,248 metric tons of CO2e||4.8 metric tons of CO2e||23.7 metric tons of CO2e||N/A|
Emissions Inventory Methodology and Boundaries
|Start date of the 12-month period covered in this report||July 1, 2007|
|Consolidation methodology used to determine organizational boundaries||Operational control 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 ASU Research Park, a research partnership complex, does not house any residential, academic, university operations or student involved research activities. The majority of the buildings are owned and operated by entities external to the university.
|Emissions calculation tool used||Clean Air-Cool Planet|
Please describe why this tool was selected.
The CA-CP Campus Carbon Calculator was recommended in the ACUPCC reporting system instructions. The CA-CP tool was also used because of its ease of use by interested parties and it was the tool used for our fy' 06 baseline study.
Please describe the source(s) of the emissions coefficients used.
CA-CP Campus Carbon Calculator's default emissions coefficients.
|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.
Inventory data was collected from a wide variety of campus sources for seven primary categories of greenhouse gas emission activities:
Please describe any emissions sources that were classified as de minimis and explain how a determination of the significance of these emissions was made.
No information provided
Please describe any data limitations related to this submission and any major assumptions made in response to these limitations.
Results of this inventory are highly contingent on the availability and quality of the data on which emissions calculations are based. In many cases data were not available to provide a complete historical perspective without assumptions or extrapolation. Where multiple years of data were available, they were extrapolated forward or backward where possible.

|Biogenic Emissions from Stationary Combustion||0.0 metric tons of CO2e|
|Biogenic Emissions from Mobile Combustion||0.0 metric tons of CO2e|
|Carbon offsets purchased||0.0 metric tons of CO2e|
|Offset verification program(s)||No information provided|
Description of offsets purchased (including vendor, project source, etc.)
|Renewable Energy Certificates (RECs)|
|Total RECs purchased||0 kWh|
|Percent of total electricity consumption mitigated through the purchase of RECs||0.0 %|
|Emissions reductions due to the purchase of RECs||0.0 metric tons of CO2e|
|REC verification program(s)||No information provided|
Description of RECs purchased (including vendor, project source, etc.)
A small number of RECs have been purchased related to new buildings LEED assignments. Any credit related to these purchases has been omitted due to their minimal influence on our overall footprint.
|Sequestration and Carbon Storage|
|Sequestration due to land owned by the institution||0.0 metric tons of CO2e|
Description of how sequestration was calculated
ASU has no carbon sequestration projects for its campus emmissions underway at this moment, however several research projects in this area (such as promising cyanobacteria)are being investigated for possible implementation.
|Carbon storage due to composting||22.0 metric tons of CO2e|
