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 recommended tool of the American College & University Presidents Climate Commitment (ACUPCC).

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.
