Data source(s) and notes about the submission:
The baseline year was adopted to be consistent with reporting on the University of Waterloo’s Climate Action Plan – Shift: Neutral. This base year was highly representative in terms of heating degree day weather influences, and mitigated the substantial historical changes in reduction of scope 2 emissions because of provincial coal power phase-out, which was outside the University’s scope of control.
There are discrepancies between the weighted campus users reported here and in PRE-5 due to timing of submission to account for COVID-19 disruption. The PRE credits reflected most recent numbers from Fall 2020, in which the vast majority of students were in online learning, and campus operations were significantly reduced. As this is not at all indicative of normal and expected future operations, Waterloo has submitted 2019 data for both energy consumption and for headcounts to be more representative.
Similarly, the space discrepancies between PRE-4 and this submission are a result of PRE-4 reporting most recent/accurate (2020), and this credit reporting most representative (2019) given significant changes to campus operations from COVID-19.
