| Total | 25,558.50 Metric tons of CO2 equivalent | 23,094.77 Metric tons of CO2 equivalent |
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 |
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 Scope 1 and Scope 2 GHG emissions:
| Performance year | Baseline year | |
| Adjusted net GHG emissions | 25,538.67 Metric tons of CO2 equivalent | 23,074.94 Metric tons of CO2 equivalent |
Start and end dates of the performance year and baseline year (or three-year periods):
| Performance year | Baseline year | |
| Start date | July 1, 2018 | July 1, 2017 |
| End date | June 30, 2019 | 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.
Current values for baseline year updated based on last year's report (LS 12.13.19)
Figures needed to determine “Weighted Campus Users”:
| Performance year | Baseline year | |
| Number of students resident on-site | 1,912 | 2,101 |
| Number of employees resident on-site | 12 | 12 |
| Number of other individuals resident on-site | 20 | 20 |
| Total full-time equivalent student enrollment | 3,855.10 | 3,915 |
| Full-time equivalent of employees | 751.60 | 749 |
| Full-time equivalent of students enrolled exclusively in distance education | 13.50 | 6.60 |
| Weighted Campus Users | 3,945.90 | 4,041.30 |
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 | 6.47 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:

Data source(s) and notes about the submission:
Scope 3 Emissions can be found on the CSV file attached above from SIMAP. Commuting data comes from a transportation survey conducted with students, staff, and faculty. That survey is mentioned and attached in OP-15. (1.22.19 JW)
Paper purchasing only includes purchases through printing services, which accounts for around 1/2 of total paper purchased. All other departments purchase their own paper separately. (NL 1/22/19)
Purchased goods and services includes food. (JW 1.25.19)
Data revision April 26, 2019 in response to reviewers.
(1) Unmark any pursuit of "other categories" in the Scope 3 GHG Inventory.
(2) Changed the GHG Inventory to include details about distribution and transmission losses from purchased electricity. (NL 4.26.2019)
