Greenhouse gas (GHG) inventories are becoming a common measure of environmental impact and sustainability for institutions. The University of Illinois in Chicago (UIC) prepared a GHG inventory for fiscal years 2004–2008. UIC conducted a commuter survey to obtain data regarding the commuting habits of its faculty, staff, and students. In fiscal year 2008, UIC's carbon footprint was not significantly higher than the 2004 emissions (275,000 vs. 273,000 metric tons of carbon dioxide equivalents, respectively). For 2008, the largest source of emissions was buildings (83%), followed by commuting (16%) and waste (1%). When compared to 85 other doctorate-granting universities, UIC's gross emissions per square foot (21.4%) are lower than average. The variation in the emissions over the five years studied is largely influenced by the amount of electricity purchased and the mix of sources of that electricity (i.e., nuclear vs. coal). Conducting a baseline GHG inventory can serve as a measure of progress toward more sustainable practices within an institution and as a tool for developing goals, strategies and policies to reduce emissions.
