Data source(s) and notes about the submission:

Please note this is for Lakeside campus only. We use 2008 as our baseline. In the meantime Loyola has acquired two academic centers and just recently got financial control of our medical campus. In order to make comparisons from the baseline consistent, we track greenhouse gases for the new area and publicly report it; however we only do our comparisons from baseline for the two main campuses in order to maintain consistency and change over time.

We may revisit this in the future once we have a history of tracking but this would reset our baseline to 2016 or sometime in which we have comparable area and use.
