Part 1. Greenhouse gas emissions inventory

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

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:
Operational control approach (The Greenhouse Gas Protocol), custom tool.

Conversion factors were used from government agencies such as US Environmental Protection Agency and organizations such as The Climate Registry.

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?:
No

A brief description of the GHG inventory verification process:
---

Documentation to support the GHG inventory verification process:
---

Scope 1 GHG emissions
Gross Scope 1 GHG emissions, performance year:
Weight in MTCO2e
Stationary combustion 2,091.88 Metric tons of CO2 equivalent
Other sources (mobile combustion, process emissions, fugitive emissions) 129.03 Metric tons of CO2 equivalent

Total gross Scope 1 GHG emissions, performance year:
2,220.91 Metric tons of CO2 equivalent

Scope 2 GHG emissions
Gross Scope 2 GHG emissions, performance year (market-based):
Weight in MTCO2e
Imported electricity 283.43 Metric tons of CO2 equivalent
Imported thermal energy 0 Metric tons of CO2 equivalent

Total gross Scope 2 GHG emissions, performance year:
283.43 Metric tons of CO2 equivalent

GHG emissions from biomass combustion
Gross GHG emissions from biogenic sources, performance year:
0 Metric tons of CO2 equivalent

Scope 3 GHG emissions
Does the GHG emissions inventory include Scope 3 emissions from the following sources?:
Yes or No Weight in MTCO2e
Business travel Yes 316.52 Metric tons of CO2 equivalent
Commuting Yes 725.50 Metric tons of CO2 equivalent
Purchased goods and services --- ---

Other sources --- ---

Total Scope 3 GHG emissions, performance year:
1,042.02 Metric tons of CO2 equivalent

A brief description of how the institution accounted for its Scope 3 emissions:
Business travel was accounted in finance records. Commuting data was collected through transportation survey (see OP-16) and calculated.
