GHG Report for Brookhaven College

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) | 2,783 metric tons of CO2e | 0.2 metric tons of CO2e | 4.4 metric tons of CO2e | 0% |
| Gross emissions (Scopes 1 + 2 + 3) | 9,478 metric tons of CO2e | 0.8 metric tons of CO2e | 14.9 metric tons of CO2e | 0% |
| Net emissions | 9,478 metric tons of CO2e | 0.8 metric tons of CO2e | 14.9 metric tons of CO2e | N/A |
Emissions Inventory Methodology and Boundaries
| Start date of the 12-month period covered in this report | September 1, 2010 |
| 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.

| Emissions calculation tool used | Clean Air-Cool Planet |
|
Please describe why this tool was selected.
This calculator is the recommended tool for higher education institutions. It is used by the reporting colleges of the Dallas County Community College District. |
|
|
Please describe the source(s) of the emissions coefficients used.
CA-CP default emissions coefficients were used. |
|
| Which version of IPCC's list of global warming potentials did you use? | Third Assessment Report |
| Who primarily conducted this emissions inventory? | Cross-functional team |
|
Please describe the process of conducting the inventory.
A cross-functional team gathered information for this inventory. Employee and student travel, van and bus fleet mileage data were supplied by the college business office. Data for energy budget, building space, natural gas and electricy use, police and college fleet, solid waste, refrigerants and other emissions were provided by Facilities Services. Office of Institutional Effectiveness, Planning, and Research provided information about commuter miles; as well as employee population; and student enrollment based on 2010 Fall IPEDS. IR also worked all conversions. |
|
|
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.
We based commuter mileage estimates on the following assumptions: zip codes and distance from campus; faculty commutes 31 weeks per year @4 x per week; students 31 weeks per year @4 x per week. Staff 48 weeks per year @5 x per week. Information about ridership on bus and rail was based on individual disclosure. |

Please describe any circumstances specific to your institution that provide context for understanding your greenhouse gas emissions this year.
Since the 2008 GHG report was submitted, the college has opened new buildings and additions that total approximately 184,372 sq. feet. We speculate that bringing these buildings online (as opposed to contractors' running utilities) combined with lighting retrofits, installation of a new chiller, and college-wide efforts to conserve electricity have helped to reduce electricity use. Implementation of single stream recycling in interior campus spaces, offices and work areas may have contributed to lowering solid waste statistics. However, our inventory team is still learning how to gather, estimate and convert data statistics. Thus the differences in present and past inventories. |
