GHG Report for University of Hawai'i at Manoa
Submitted on September 15, 2008; last updated on November 21, 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, 2008|
|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 University of Hawai‘i at Mānoa (UH Mānoa) is one of several institutions within the University of Hawai‘i System. Our inventory was carried out for the operations of the main campus of the University of Hawaii at Manoa (UHM). There are several centers beyond the physical boundary of this campus that are structurally organized under UHM, but are not under UHM’s operational control. Our team decided that our efforts would best serve the UH System, the greater Hawaii community and the goals of the ACUPCC to carry out the inventory of the main campus with clearly defined boundaries. Having ascended the steep learning curve for Hawaii's unique circumstances for our main campus, we can then proceed to educate the other centers and schools on the process. This is especially important considering Hawaii spreads over several islands.
|Emissions calculation tool used||Custom tool|
Please describe why this tool was selected.
We found useful approaches in both the Clean Air Cool Planet calculation tool and the World Resources Institute / World Business Council for Sustainable Development Greenhouse Gas Protocol. Neither was entirely appropriate for our circumstances so we developed an inventory that drew from these tools, the IPCC guidance documents, EPA guidance documents, and other commonly referenced materials for calculating emissions. Though all colleges and universities in the ACUPCC program likely have significant air travel emissions and unique emission factors from their operations/locations, Hawaii, being the most physically isolated islands in the world, represents a unique challenge in developing the right tool with which to use. We continue to extensively research more accurate and specific emission factors for energy and non-energy sources of GHG emissions and expect to provide the greater Hawaii Community with a comprehensive list of Hawaii-specific coefficients in the near future.
Please describe the source(s) of the emissions coefficients used.
Synthetic Natural Gas (SNG) (Stationary Combustion) (Scope 1) - default factors from the WRI Cross-Sector Tools/WBCSD GHG Protocol.
|Which version of IPCC's list of global warming potentials did you use?||Fourth Assessment Report|
|Who primarily conducted this emissions inventory?||Student researcher(s)|
Please describe the process of conducting the inventory.
The Energy and Greenhouse Gas Solutions (EGGS) team at the University of Hawai‘i Economic Research Organization (UHERO) conducts the reporting process. We identified emission sources by reviewing fuel and utility services with the Vice Chancellor for OFG and directly contacted each manager responsible for operations requiring those specific fuels. Data is collected from each manager through email correspondences in different formats and is then aggregated into a master excel spreadsheet. The Office of Assistant Vice Chancellor verifies the findings for Facilities and Grounds (OFG), and if needed, EGGS will make adjustments to the compiled data before acquiring approval from the Assistant Vice Chancellor of OFG for TCR submittal. To ensure further quality assurance, the UH Mānoa Sustainability Corp also reviews the findings.
Please describe any emissions sources that were classified as de minimis and explain how a determination of the significance of these emissions was made.
Based on Arizona and Florida’s similar climate to Hawai‘i and their fugitive emissions consisting of less than 5% of their total emissions, Hawai‘i is also excluding these emission sources.
Please describe any data limitations related to this submission and any major assumptions made in response to these limitations.
To be consistent and for the ease/simplicity of calculation given the format of and data set available, all emission factors were taken from the WRI GHG Protocol Initiative. Due to the information set available for mobile vehicles, N2O and CH4 emission factors for 2010 were calculated based on WRI’s GHG Protocol Initiative and additional assumptions. Because detailed data on mobile vehicles was not available for 2008 and 2009, CO2, CH4, and N2O emission factors were based on an average of 2010 emission factors.

Please describe any circumstances specific to your institution that provide context for understanding your greenhouse gas emissions this year.
The Climate Registry (TCR) is the primary reporting program UHM is using to track greenhouse gas emissions. TCR does not require reporting Scope 3 emissions and therefore at this time, we are not reporting Scope 3 emissions. We consider tracking Scope 3 emissions important, but as a matter of triage, we are currently focusing on Scope 1 and 2, and are always evaluating opportunities to include Scope 3.
