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:

Central_2019GHGinventorywithScope3.xlsx

A brief description of the methodology and/or tool used to complete the GHG emissions inventory:

Annual Greenhouse Gas Inventories are completed using the Washington State Department of Ecology Greenhouse Gas Calculator. It includes; 1) building energy use, 2) fleet energy use, and 3) employee business travel and commuting

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?:

A brief description of the GHG inventory verification process:

n/a

Documentation to support the GHG inventory verification process:

Scope 2 GHG emissions

Gross Scope 2 GHG emissions, performance year (market-based):

	Weight in MTCO2e
Imported electricity	159.29 Metric tons of CO2 equivalent
Imported thermal energy	1,046.89 Metric tons of CO2 equivalent

Total gross Scope 2 GHG emissions, performance year:

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	285.40 Metric tons of CO2 equivalent
Commuting	Yes	525 Metric tons of CO2 equivalent
Purchased goods and services	No	---
Capital goods	No	---
Fuel- and energy-related activities not included in Scope 1 or Scope 2	No	---
Waste generated in operations	No	---
Other sources	No	---

Total Scope 3 GHG emissions, performance year:

810.40 Metric tons of CO2 equivalent

A brief description of how the institution accounted for its Scope 3 emissions:

Employee owned vehicle business travel, institution paid air travel, and employee commuting are included in our Scope 3 emissions. Employee owned business travel was calculated by dividing the amount reimbursed to employees for travel by the reimburseable rate for 2019 set by WA state, which gives us an estimate of the number of miles traveled for business. The WA State GHG calculator provides us total emissions based on number of miles traveled (exact methodology unknown). For air travel, employees must submit a travel request and input the to and from cities, as well as air travel miles. This report was downloaded and each trip verified for accurate air travel mileage. Air travel mileage is broken down into 3 categories in the WA state GHG calculator; 1) 0-300 miles, 2) 300-700 miles, 3) >700 miles. The calculator calculates the estimated emissions for the 3 mileage categories (exact methodology unknown). Employee commuting is calculated through a biennial employee Commute Trip Reduction (CTR) Survey Report via WA State Dpt. of Transportation. Based on survey results, DOT estimates drive alone rate, estimated emissions for total employment, etc. (exact methodology unknown)

Part 2. Air pollutant emissions inventory
