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:

UC Berkeley reports on ten emissions sources and analyzes emissions in three different categories:

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

The campus reports its GHG inventory to both The Climate Registry and the California Air Resources Board (CARB). Third party verification of the inventory is completed as part of the reporting process.

The UC Berkeley inventory includes all six major greenhouse gases. Scope 1 and 2 adhere to The Climate Registry protocol. Scope 3 emissions use Clean Air Cool Planet - Campus Carbon Calculator methodology/factors.

The geographic boundary for the inventory is generally defined as those buildings central to the University mission and under operational control of the campus. This includes central campus buildings, student housing and off-central campus facilities owned by the University.

The campus has performed LCA of emissions from procurement and construction on various occasions: http://sustainability.berkeley.edu/calcap/calcap-ghg-inventory


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:

UC Berkeley scope 1 and 2 inventories have been successfully 3rd party verified and reported to The Climate Registry, following the Registry protocol. Inventories for years 2005 through 2012 and 2018 have been 3rd party verified and are public. The majority of Berkeley's scope 1 and 2 emissions are 3rd party verified annually as part of the campus Cap & Trade regulation obligations to the California Air Resources Board (CARB). CARB publicly posts verified inventories on their website.

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

Commute data is derived from campuswide surveys; air travel trip data is collected annually; waste and water data is collected annually.


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) 5.78 Tons
Sulfur oxides (SOx) 0 Tons
Carbon monoxide (CO) 10.78 Tons
Particulate matter (PM) 0 Tons
Ozone (O3) 0 Tons
Lead (Pb) 0 Tons
Hazardous air pollutants (HAPs) 5.39 Tons
Ozone-depleting compounds (ODCs) 0 Tons
Other standard categories of air emissions identified in permits and/or regulations 0.01 Tons

Do the air pollutant emissions figures provided include the following sources?:
Yes or No
Major stationary sources Yes
Area sources No
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:

UC Berkeley follows methodologies as required by the Bay Area Air Quality Management District's regulatory permit conditions to complete its air emissions inventory (example: AP-42 factors, manufacturer specifications or emissions testing reports). In addition, California Air Resources Board methodologies are used as described in various regulations such as the Regulation for the Mandatory Reporting of Greenhouse Gas Emissions and the Refrigerant Management Program.

Additional documentation to support the submission:

Weight data is for the calendar year 2019. We now own the gas turbine and auxiliary boiler emissions. Regulatory reporting for permitted boilers requires documentation of annual therm usage and therm usage is not part of this submission. Some stationary source data was estimated based on typical operating usage. VOC is 0.013 tons for other regulated pollutants.

For the weights for Sulfur Oxides (SOx), Particular Matter (PM), Ozone (O3), Lead (Pb), Ozone-depleting compounds (ODCs) are not required to be inventoried per permit conditions, so "0" tons has been reported in each category.
