Data source(s) and notes about the submission:

-The greenhouse gas emissions reported include emissions from all buildings that are connected to the main campus utility systems, and more specifically, those that get electricity, steam or chilled water from the central energy plant, as well as those that are fed power from Elm Drive and Charlton Street substations. Also included are emissions from buildings that house significant campus energy-consuming programs that were once fed by these systems but have been moved off the main campus since 1990, including 701 Carnegie Center, as well as emissions from fleet vehicle fuel that is purchased by athletics, the business office (MacMillan pumps), and building services.

-The 2006 emissions data reflects an updated utility emissions factor, unlike the emissions data reported in the University’s annual Sustainability Report. The 2006 number has not been updated in the annual report for the sake of consistency; the original numbers continue to be used to track the University’s progress toward reaching its greenhouse gas emissions goal, which was established prior to the utility emissions factor being updated.

-Baseline population numbers reflect fiscal year 2006 and, for the performance year, fiscal year 2011. The number of on-campus residents does not include those living in University housing off-campus. Those living in the Graduate College are included as that building is connected to the main campus utility systems. The number of employees excludes Princeton Plasma Physics Laboratory (PPPL) staff and casual hourly temps.
