Part 1. Greenhouse gas emissions inventory
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:
All emissions are reported to the Climate Registry. The university also reports GHG emissions annually to the UC Office of the President. The Climate Registry and epa.gov provide up-to-date emission factors for each emission source. The university also uses verified emissions factors provided by its utility provider to calculate emissions. Calculated emissions are generated through utility usage, transportation, and travel data.
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:
The emission inventory has been reviewed and accounting verified by independent environmental services firm Cameron-Cole which is an approved verification body and technical assistance provider.
Documentation to support the GHG inventory verification process:

A brief description of the methodology(ies) the institution used to complete its air emissions inventory:
NOx and CO gas emissions were calculated using stack testing measured, average gas concentrations in exhaust emissions from the permitted, stationary campus sources, and multiplying the average gas concentrations times the average flow rate measured for the exhaust gasses in order to derive the mass rate for each exhaust gas (i.e., NOx and CO); the mass rate was then multiplied by the time that the emissions equipment ran during the year in order to calculate the total gas emissions mass (tons).
Concentration (mg/m^3) * Flow Rate (m^3/min) * Run Time (min) = Mass of Gas (mg) * 1 g/1000 mg * 1 lb/453.59 g * 1ton/2,000 lbs = Mass of Pollutant (tons) emitted per year
Concentration (mg/m^3) * Flow Rate (m^3/min) * Run Time (min) = Mass of Gas (mg) * 1 g/1000 mg * 1 lb/453.59 g * 1ton/2,000 lbs = Mass of Pollutant (tons) emitted per year

Data source(s) and notes about the submission:
Note: UC Merced is located in an area with relatively high air pollution and thus the best control technology is required in all equipment.
Fuel usage is submitted to local air district that estimate emissions for the San Joaquin Valley as a whole.
