If end date of the baseline year/period is 2004 or earlier, provide:

A brief description of when and why the water use baseline was adopted:

The 2015 baseline year was adopted for consistency with other energy and emissions baselines.

Data source(s) and notes about the submission:

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 water 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.
