Greenhouse Gas Emissions Inventory Reports

FY14 Update Findings

Total Emissions

Scope t CO2e
Net Reported Emissions 59,303
Scope 1 & 2  26,743
Adjusted Scope 1 & 2 (Includes REC Sales)* 39,041
Scope 3 20,573


Biogenic Emissions:  **150
Forest Sequestration *** -2,200


Percentage Change

Base Year  


FY1990 (First year measured)


FY2001 (Reduction baseline: Adjusted****)


FY2011 (last year measured)


GOAL (by 2010) 50% compared to 2001

STILL NEED TO REDUCE: Roughly 4,000 MTeC02, or nearly twice the amount sequestered in our campus forests.  (This assumes we stop selling EcoLine RECs.)

Intensity Demographics

Indicator   t CO2e

Per student

Per 2,000 sq.ft.  

3.4 (2.8)

Per 1,000 sq. ft. 9.3 (7.7)


*See the SI website  for explanation

** Using biofuels like B20 results in CO2 emissions, but these are reported in a separate “biogenic” category because they are considered to be carbon neutral in the long term.

***These sequestered emissions are not considered as part of the “net” calculation because they are not “additional;” see the ACUPPCC GHG Inventory Protocol for more.

**** Adjusted to account for addition of air travel to GHGI to 2001 baseline. Air travel emissions are “backcasted” to 2001, the baseline year used for setting reduction goals in WildCAP.  This was done by attributing the average annual amount estimated over the past five years (since this data collection began) to all years previous.  UNH did not start collecting or reporting data regarding Air Travel until 2009.


As the nation continues to struggle in search of a viable energy policy, and as the signs continue to mount of climate change already occuring, universities and colleges have the opportunity to demonstrate the feasibility and economic advantage of increasing energy conservation and efficiency and therefore decreasing emissions. In 2000, the University of New Hampshire's sustainability program partnered with Clean Air - Cool Planet to produce a greenhouse gas emissions calculator - the Campus Carbon Calculator - adapted for the scale and character of a university community. This tool is now being used by over 2,300 campuses across North America and is the tool recommended by Second Nature for the signatories of The Presidents' Climate Leadership Commitment.

Current Projects

Long Distance Travel Emissions

Starting in FY10, the Energy Task Force, working with the various Business Service Centers (BSCs) on campus, began collecting data on purchases of airline tickets that will enable us to estimate the Scope 3 emissions associated with university-funded travel. The number of people authorized to purchase airline tickets is limited, and most of them do so with a university-issued credit card. The credit card provider can generate a list of these transactions and the costs used to estimate miles traveled and therefore emissions. This method may exclude anyone who purchases a ticket in advance and is then reimbursed by the university, a practice which is not widespread but occurs regularly in some of the colleges and academic units. The method also does not factor out air travel fees and taxes, therefore slightly overestimating miles traveled. However, this process should provide a reasonable estimate of overall travel emissions. All air travel purchases made on UNH credit cards held by university employees (called “p-cards”) are translated into miles in accordance with an emissions factor of $0.15/mile provided by Clean Air-Cool Planet in the Campus Carbon Calculator.
