Gross Scope 2 GHG emissions from imported thermal energy	0 Metric tons of CO2 equivalent	0 Metric tons of CO2 equivalent
Total	13,664.52 Metric tons of CO2 equivalent	25,576.20 Metric tons of CO2 equivalent

Carbon sinks

Figures needed to determine net carbon sinks:

	Performance year	Baseline year
Third-party verified carbon offsets purchased	0 Metric tons of CO2 equivalent	0 Metric tons of CO2 equivalent
Institution-catalyzed carbon offsets generated	0 Metric tons of CO2 equivalent	0 Metric tons of CO2 equivalent
Carbon storage from on-site composting	35 Metric tons of CO2 equivalent	11 Metric tons of CO2 equivalent

If total performance year carbon sinks are greater than zero, provide:

A brief description of the carbon sinks, including vendor, project source, verification program and contract timeframes (as applicable):

We have a large on-campus composting facility that receives all material from our campus grounds. All food waste compost get sent off campus to Green Earth Technology.

Adjusted net GHG emissions

Adjusted net Scope 1 and Scope 2 GHG emissions:

	Performance year	Baseline year
Adjusted net GHG emissions	13,629.52 Metric tons of CO2 equivalent	25,565.20 Metric tons of CO2 equivalent

Performance and baseline periods

Start and end dates of the performance year and baseline year (or three-year periods):

	Performance year	Baseline year
Start date	July 1, 2021	July 1, 2005
End date	June 30, 2022	June 30, 2006

A brief description of when and why the GHG emissions baseline was adopted:

Fiscal year 2006 (July 1, 2005 to June 30, 2006) was the first year that Western employed staff able to collect and analyze carbon emissions data.

Part 1. Reduction in GHG emissions per person

Weighted campus users

Figures needed to determine “Weighted Campus Users”:

	Performance year	Baseline year
Number of students resident on-site	3,383	3,853
Number of employees resident on-site	0	0
Number of other individuals resident on-site	0	0
Total full-time equivalent student enrollment	14,450	12,343
Full-time equivalent of employees	4,635	1,286
Full-time equivalent of students enrolled exclusively in distance education	255	0
Weighted Campus Users	14,968.25	11,185

Metrics used in scoring for Part 1

Adjusted net Scope 1 and 2 GHG emissions per weighted campus user:

	Performance year	Baseline year
Adjusted net Scope 1 and 2 GHG emissions per weighted campus user	0.91 Metric tons of CO2 equivalent	2.29 Metric tons of CO2 equivalent

Percentage reduction in adjusted net Scope 1 and Scope 2 GHG emissions per weighted campus user from baseline:

60.16

Part 2. GHG emissions per unit of floor area

Floor area of energy intensive building space, performance year:

	Floor area
Laboratory space	767,271 Square feet
Healthcare space	0 Square feet
Other energy intensive space	0 Square feet

EUI-adjusted floor area, performance year:

5,076,567 Gross square feet

Metric used in scoring for Part 2

Adjusted net Scope 1 and 2 GHG emissions per unit of EUI-adjusted floor area, performance year:

0.00 MtCO2e per square foot

A brief description of the institution’s GHG emissions reduction initiatives:

WWU has worked to both reduce GHG emissions through building efficiency upgrades to reduce our SCOPE 1-2 emissions as well as enacted the Sustainability Action Plan intended to reduce and mitigate impacts of our Scope 3 Emissions. In addition to this ongoing work, we completed a feasibility study and requested funding for the conversion of our steam plant to be a GHG neutral thermal system to support our operations into the next century. This work is coordinated with the intention to ensure that our university is holistic in our approach to managing all scopes of our emissions profile and strategic in our focus areas of intervention namely our steam plant and utility offsets for our resource and energy use.
