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:

UCI reports on emissions sources and analyzes emissions for the following scopes:

Scope 1 - Direct Emissions: cogeneration plant natural gas, purchased natural gas, emergency generators, campus fleet, emissions from refrigerants
Scope 2 - Indirect Emissions: purchased electricity
Scope 3 - Other Emissions: business air travel, student commute, faculty/staff commute, solid waste, water

Using the financial control approach to determine organizational boundaries, UCI gathers a comprehensive annual inventory of greenhouse gas emission sources on campus. These data sets are reviewed, analyzed, and publicly reported using The Climate Registry General Reporting Protocol Version 3.0.

Scope 3 emissions inventoried annually include commuting and university-paid air travel. GHG emissions associated with commuting are calculated by UCI Transportation and Distribution Services using AQMD survey data. University-paid air travel miles is collected through the UCI accounting office.


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 GHG inventory verification process:

UCI submits its greenhouse gas emission inventory report to a third party verification party annually. This independent verification process reviews the emission inventory against the Climate Registry's General Reporting Protocol 3.0 following the procedures outlined in the Registry’s General Verification Protocol 3.0.


Documentation to support the GHG inventory verification process:
Gross Scope 1 GHG emissions, performance year:
Weight in MTCO2e
Stationary combustion 69,089 Metric Tons of CO2 Equivalent
Other sources (mobile combustion, process emissions, fugitive emissions) 8,927 Metric Tons of CO2 Equivalent

Total gross Scope 1 GHG emissions, performance year:
78,016 Metric Tons of CO2 Equivalent

Gross Scope 2 GHG emissions, performance year (market-based):
Weight in MTCO2e
Imported electricity 1,035 Metric Tons of CO2 Equivalent
Imported thermal energy 0 Metric Tons of CO2 Equivalent

Total gross Scope 2 GHG emissions, performance year:
1,035 Metric Tons of CO2 Equivalent

Gross GHG emissions from biogenic sources, performance year:
0 Metric Tons of CO2 Equivalent

Does the GHG emissions inventory include Scope 3 emissions from the following sources?:
Yes or No Weight in MTCO2e
Business travel Yes 42,682 Metric Tons of CO2 Equivalent
Commuting Yes 10,874 Metric Tons of CO2 Equivalent
Purchased goods and services --- 0 Metric Tons of CO2 Equivalent
Capital goods --- 0 Metric Tons of CO2 Equivalent
Fuel- and energy-related activities not included in Scope 1 or Scope 2 --- 0 Metric Tons of CO2 Equivalent
Waste generated in operations --- ---
Other sources --- 0 Metric Tons of CO2 Equivalent

Total Scope 3 GHG emissions, performance year:
53,556 Metric Tons of CO2 Equivalent

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

Scope 3 emissions inventoried annually include commuting and university-paid air travel. GHG emissions associated with commuting are calculated by UCI Transportation and Distribution Services using AQMD survey data. University-paid air travel miles is collected through the UCI accounting office.


Has the institution completed an inventory within the previous three years to quantify its air pollutant emissions?:
Yes

Annual weight of emissions for::
Weight of Emissions
Nitrogen oxides (NOx) 8.43 Tons
Sulfur oxides (SOx) 1.61 Tons
Carbon monoxide (CO) 5.56 Tons
Particulate matter (PM) 8.55 Tons
Ozone (O3) ---
Lead (Pb) ---
Hazardous air pollutants (HAPs) 0.99 Tons
Ozone-depleting compounds (ODCs) 0.24 Tons
Other standard categories of air emissions identified in permits and/or regulations ---

Do the air pollutant emissions figures provided include the following sources?:
Yes or No
Major stationary sources Yes
Area sources Yes
Mobile sources No
Commuting No
Off-site electricity production No

A brief description of the methodology(ies) the institution used to complete its air emissions inventory:

The methods used to complete the air emissions inventory include:
1. Continuous monitoring to measure actual emissions;
2. Extrapolating the results from source emissions tests;
3. Combining published emission factors with known activity levels;
4. And using emission factor to estimate emissions when actual emission data is not available.
