GHG Report for Massachusetts College of Liberal Arts
Submitted on September 15, 2008; last updated on December 26, 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.
|Total||Per Full-Time Enrollment||Per 1000 Square Feet||% Offset|
|Gross emissions (Scopes 1 + 2)||6,618 metric tons of CO2e||3.6 metric tons of CO2e||9.9 metric tons of CO2e||10%|
|Gross emissions (Scopes 1 + 2 + 3)||8,015 metric tons of CO2e||4.4 metric tons of CO2e||12.0 metric tons of CO2e||9%|
|Net emissions||7,325 metric tons of CO2e||4.0 metric tons of CO2e||10.9 metric tons of CO2e||N/A|
Emissions Inventory Methodology and Boundaries
|Start date of the 12-month period covered in this report||January 1, 2007|
|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.
None were omitted.
|Emissions calculation tool used||Clean Air-Cool Planet|
Please describe why this tool was selected.
The tool was appropriate for our campus. In addition, a neighboring institution had found the CA-CP tool valuable and recommended its use. For this updated 2007 GHG report, we used the 6.4 version of the Clean Air-Cool Planet calculator.
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?||Initially an external consultant and for this update, the sustainability coordinator.|
Please describe the process of conducting the inventory.
An external consultant, the Center for Ecological Technology (CET), conducted an inventory of waste and recycling. A student supervised by a faculty member collected the initial energy data. Energy data was transferred to CET staff members who worked with college staff including facilities managers, the VP of Administration and Finance and the institutional research offices to collect additional data to complete the original 2007 report. This updated 2007 Greenhouse Gas Report includes data from more recent Clean Air Cool Planet carbon calculator, version 6.4.
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.
A significant limitation of the CA-CP tool relates to emissions associated with waste. Waste from MCLA goes to a waste-to-energy facility. We found that the tool calculates a decrease in GHG emissions as waste increases. This is counter to the recommendation that it is most beneficial to reduce and recycle waste at the college.

Auditing and VerificationThese emissions data have been audited, verified, or peer-reviewed.
Please briefly describe this verification, if any.
The data for the calculations for the MCLA carbon footprint were verified by the MCLA staff. *Note: Since the completion of the initial 2007 GHG report, MCLA has began to use the 6.4 CA-CP software, and has conducted the emissions inventory internally starting in 2008. This change in software and identification of new sources of data on campus, results in the discrepancies between the figures in this updated 2007 GHG report, and the data presented in the 2009 Climate Action Plan.*
