"---" indicates that no data was submitted for this field

Has the institution conducted a GHG emissions inventory that includes all Scope 1 and 2 emissions? :
Yes

Does the institution’s GHG emissions inventory include all, some or none of its Scope 3 GHG emissions from the following categories?:
All, Some, or None
Business travel None
Commuting None
Purchased goods and services None
Capital goods None
Waste generated in operations None
Fuel- and energy-related activities not included in Scope 1 or Scope 2 None
Other categories None

A copy of the most recent GHG emissions inventory:
A brief description of the methodology and/or tool used to complete the GHG emissions inventory, including how the institution accounted for each category of Scope 3 emissions reported above:
The inventory is conducted by EPA reporting standards. The attached file is the data reported to the EPA in 2016 available at the following address: https://ghgdata.epa.gov/ghgp/service/facilityDetail/2016?id=1004790&ds=E&et=&popup=true

Has the GHG emissions inventory been validated internally by personnel who are independent of the GHG accounting and reporting process and/or verified by an independent, external third party?:
Yes

A brief description of the internal and/or external verification process:
Scope 1 emissions are accounted for by EPA standards and Scope 2 are verified by University billing.

Documentation to support the internal and/or external verification process:
---

Does the institution wish to pursue Part 2 and Part 3 of this credit? (reductions in Scope 1 and Scope 2 GHG emissions):
Yes

Gross Scope 1 and Scope 2 GHG emissions:
Performance Year Baseline Year
Gross Scope 1 GHG emissions from stationary combustion 159,611 Metric tons of CO2 equivalent 284,326.07 Metric tons of CO2 equivalent
Gross Scope 1 GHG emissions from other sources 0 Metric tons of CO2 equivalent 0 Metric tons of CO2 equivalent
Gross Scope 2 GHG emissions from purchased electricity 139,143 Metric tons of CO2 equivalent 263,613.93 Metric tons of CO2 equivalent
Gross Scope 2 GHG emissions from other sources 0 Metric tons of CO2 equivalent 0 Metric tons of CO2 equivalent
Total 298,754 Metric tons of CO2 equivalent 547,940 Metric tons of CO2 equivalent

Start and end dates of the performance year and baseline year (or three-year periods):
Start Date End Date
Performance Year July 1, 2016 June 30, 2017
Baseline Year July 1, 2004 June 30, 2005

A brief description of when and why the GHG emissions baseline was adopted (e.g. in sustainability plans and policies or in the context of other reporting obligations):
The baseline year of 2005 was adopted because it was the year in which the University of Iowa joined the Chicago Climate Exchange (which has since been disbanded) and was thus an important year for setting goals in sustainability for the University.

Figures needed to determine total carbon offsets:
Performance Year Baseline Year
Third-party verified carbon offsets purchased (exclude purchased RECs/GOs) 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 sequestration due to land that the institution manages specifically for sequestration 0 Metric tons of CO2 equivalent 0 Metric tons of CO2 equivalent

Net carbon offsets 0 Metric tons of CO2 equivalent 0 Metric tons of CO2 equivalent

Data source(s) and notes about the submission:
Emissions from UI Hospitals and Clinics are included; it is impossible to separate these figures from Main Campus emissions. At this time, the Clean Air/Cool Planet protocol does not allow reporting of biogenic CO2 emissions reductions derived from oat hulls. The University of Iowa has been using oat hulls as a biomass fuel since 2003. The 2005 data, originally, was not disaggregated into Scope 1 emissions and Scope 2 emissions, so the average ratio of three historic years (FY17 - performance year, FY14, FY12) was calculated and applied to the sum of Scope 1 and 2 emissions (which is the number that was provided to us) to derive approximations for Baseline year FY2005.
