Some campus units (or individual faculty or staff) may wish to voluntarily offset their carbon emissions, for example from air travel to scholarly meetings.  iSEE could work with the Office of Business and Financial Services (OBFS) to develop an administrative mechanism that would allow such units to “buy in” to periodic campus-wide purchases of verified offsets.  For example, iSEE could execute a campus-wide purchase of offsets at the start of each year, resell offsets to interested units throughout the year, and then increase the next year’s campus-wide purchase to replenish what had been sold to units.  This mechanism, which could be in place by the end of FY17, would allow units and individuals to directly engage in emission reduction activities, above and beyond campus-wide initiatives.
