GHG Report for Chatham University

Submitted on January 14, 2011; last updated on December 16, 2011

Summary Statistics

Making 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) 13,574 metric tons of CO2e 8.1 metric tons of CO2e 13.8 metric tons of CO2e 21%
Gross emissions (Scopes 1 + 2 + 3) 15,222 metric tons of CO2e 9.1 metric tons of CO2e 15.5 metric tons of CO2e 19%
Net emissions 12,339 metric tons of CO2e 7.4 metric tons of CO2e 12.5 metric tons of CO2e N/A

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.

In previous years, students, faculty and staff had to purchase a validation sticker for public transit, and we were able to collect ridership data. All Chatham ID cards now work as a free public transit pass, stickers no longer required. Therefore, we are unable to determine bus and rail ridership reliably this year. We are looking at new ways to collect that for next year.

EDIT: discovered our compost conversions were inaccurate. Edited to reflect corrections. 12-1-2011

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.

Shadyside campus has 12 acres of tree cover, so the total acreage of tree cover for Chatham is 272.

Carbon storage due to composting 244.0 metric tons of CO2e

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.
