Scope 1 and Scope 2 GHG emissions

Gross GHG emissions

Gross Scope 1 and Scope 2 greenhouse gas (GHG) emissions:

	Performance year	Baseline year
Gross Scope 1 GHG emissions from stationary combustion	9,515.72 Metric tons of CO2 equivalent	9,723.08 Metric tons of CO2 equivalent
Gross Scope 1 GHG emissions from other sources	406.78 Metric tons of CO2 equivalent	422.89 Metric tons of CO2 equivalent
Gross Scope 2 GHG emissions from imported electricity	9,517 Metric tons of CO2 equivalent	12,948.80 Metric tons of CO2 equivalent
Gross Scope 2 GHG emissions from imported thermal energy	0 Metric tons of CO2 equivalent	0 Metric tons of CO2 equivalent
Total	19,439.50 Metric tons of CO2 equivalent	23,094.77 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	19.83 Metric tons of CO2 equivalent	19.83 Metric tons of CO2 equivalent
Carbon storage from non-additional sequestration	0 Metric tons of CO2 equivalent	0 Metric tons of CO2 equivalent
Carbon sold or transferred	0 Metric tons of CO2 equivalent	0 Metric tons of CO2 equivalent
Net carbon sinks	19.83 Metric tons of CO2 equivalent	19.83 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):

Composting at Calvin is broken into two categories, dining waste that is taken by a third party, made into compost, and sold as soil and grounds compost. The grounds compost is taken to an external site by Calvin and managed by Calvin staff. The resulting soil is either donated to Habitat for Humanity or Plaster Creek Stewards, brought back to Calvin to be used on the grounds or sold to landscaping companies.

Sequestration is from the Dave Warners/Jack Phillips report in 2015 and attached at the end of this credit ("Carbon Budget Overview Summary"). - Did not use 18/19 years K.M

The carbon storage from on-site composting comes from the SIMAP data sheet under "waste generated in operations" - data from Henry Kingma.

Adjusted net GHG emissions

Adjusted net Scope 1 and Scope 2 GHG emissions:

	Performance year	Baseline year
Adjusted net GHG emissions	19,419.67 Metric tons of CO2 equivalent	23,074.94 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, 2017
End date	June 22, 2022	June 30, 2018

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

The baseline year was selected because it is after major renovations and building construction. The baseline year is recent enough to capture reliable data from the past and assess progress on sustainability efforts.

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	1,920	2,101
Number of employees resident on-site	15	12
Number of other individuals resident on-site	9	20
Total full-time equivalent student enrollment	3,372	3,915
Full-time equivalent of employees	594	749
Full-time equivalent of students enrolled exclusively in distance education	194	6.60
Weighted Campus Users	3,321.75	4,041.30

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	5.85 Metric tons of CO2 equivalent	5.71 Metric tons of CO2 equivalent

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

Part 2. GHG emissions per unit of floor area

Performance year floor area

Gross floor area of building space, performance year:

2,197,026 Gross square feet

Floor area of energy intensive building space, performance year:

	Floor area
Laboratory space	57,530 Square feet
Healthcare space	3,452 Square feet
Other energy intensive space	85,557 Square feet

EUI-adjusted floor area, performance year:

2,404,547 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:

0.01 MtCO2e per square foot

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

Currently working with Foresight management to evaluate all of our HVAC controls to ensure maximum efficiency.
