Vanderbilt University operates an on-site, natural gas fueled co-generation power plant that meets the steam and a portion of the chilled water needs of the University and Medical Center and 29% of the electrical needs. The remaining 71% electrical need is purchased from the Tennessee Valley Authority through Nashville Electric Service (NES). Vanderbilt emits Greenhouse Gases (GHGs) through these two processes as well as university fleet vehicle use, refrigerant releases, faculty, and staff commuting to work, air travel paid for by the University, and waste disposal and recycling. The six GHGs emitted into the atmosphere that comprise the majority of the carbon footprint are: carbon dioxide (CO2); methane (CH4); nitrous oxide (N2O); hydrofluorocarbons (HFCs); perfluorocarbons (PFCs); and sulfur hexafluoride (SF6). The amount of emissions of each gas are converted to a standard unit of measure, or metric tons of carbon dioxide equivalents (MTCO2E) and then summed to determine Vanderbilt’s carbon footprint. Vanderbilt University became an independent legal entity from VUMC on May 1, 2016. Vanderbilt University is now smaller in both number of people and square feet without the Medical Center, and therefore, so are the 2016 and forward Greenhouse Gas inventories in comparison to previous inventories (2005-2015). Because of the significant shift in GHG footprint due to the new organization, 2005-2015 GHG data is archived.
