GHG Report for Chatham University
Submitted on January 14, 2011; last updated on December 16, 2011
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.

Emissions Inventory Methodology and Boundaries
|Start date of the 12-month period covered in this report||January 1, 2009|
|Consolidation methodology used to determine organizational boundaries||Financial 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.
|Emissions calculation tool used||Clean Air-Cool Planet|
Please describe why this tool was selected.
Recommended by ACUPCC
Please describe the source(s) of the emissions coefficients used.
CA-CP Campus Carbon Calculator's default emissions co-efficients.
|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.
Data collected from head of facilities, utility records, vendors, etc. Most data were readily available from facilities and financial records.
Please describe any emissions sources that were classified as de minimis and explain how a determination of the significance of these emissions was made.
Please describe any data limitations related to this submission and any major assumptions made in response to these limitations.
We are still tightening up our commuting data collection. Commuting distance calculated from center of resident zip code to Chatham, with full-time students calculated at 5 days per week and part-time students calculated at 3 days per week. Faculty and staff commuting miles were combined this year, with data taken from parking permit records.

Vendor: Renewable Choice Energy
|Sequestration and Carbon Storage|
|Sequestration due to land owned by the institution||272.0 metric tons of CO2e|
Description of how sequestration was calculated
Tree cover at Eden Hall Farm calculated using GIS: 4 large stands of trees (7,656,562, 3,023,340, 527,352, and 35,708 sq ft) individual trees added up to an additional 65,312 sq feet. This is a total of 11,308,274 square feet of tree cover. Divided by 43,560 (sq ft in an acre), this is 259.6 acres.
|Carbon storage due to composting||244.0 metric tons of CO2e|
Normalization and Contextual Data
|Gross square feet of building space||984,000.0 sq ft|
|Net assignable square feet of laboratory space||60,000.0 sq ft|
|Net assignable square feet of health care space||No information provided|
|Net assignable square feet of residential space||No information provided|
|Total Student Enrollment (FTE)||1676.0|
|Full-time Commuter Students||958|
|Part-time Commuter Students||827|
|Non-Credit Students||No information provided|
|Other Contextual Data|
|Heating Degree Days||5627|

Please describe any circumstances specific to your institution that provide context for understanding your greenhouse gas emissions this year.
We are beginning to see the benefits of the Green Machine shuttles, with steadily increasing ridership (over 1,000 per week) and trips to shopping and entertainment venues. Some energy efficiency measures at Eastside beginning to show up in lower electricity totals. Changes to Chathams' Study Abroad program reduced travel miles for 2009, but totals are expected to rise agian next year. Changes to public transit pass system left a gap in our ability to calculate bus and light rail miles this year.

Auditing and VerificationThese emissions data have been audited, verified, or peer-reviewed.
Please briefly describe this verification, if any.
Verified through utility billing, credit card receipts, parking permits, etc.
