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:
The Sustainability Center and Facilities Management gathered the needed information and used Second Nature's Sustainability Indicator Management and Analysis Platform (SIMAP) to complete the GHG inventory. Additional tools used when more comprehensive tools were available, such as the EPA’s Waste Reduction Model (WARM) for solid waste emissions.
Methodology/tools used:
Scope 1: Data collected from bills to the university (natural gas and fuels) and relevant inventories (animal counts and HVAC refrigerants)
Scope 2: Data collected from utility provider bills to the university
Scope 3:
- Business travel: Air travel data is provided by the Accounts Payable Office.
-Commuting: Data is based on a 2018 commuter survey, fitted to population data.
-Waste: Data provided by Facilities includes landfilled waste after removing recyclable and compostable materials. EPA’s WARM calculator used.
-Food: Data collected by Sodexo in 2019 and fitted to population data for subsequent years.

A brief description of the methodology(ies) the institution used to complete its air emissions inventory:
To complete its air emissions inventory, the UI uses “Method 5” by the Idaho Department of Environmental Quality (IDEQ) and the Environmental Protection Agency (EPA).
Particulate matter is withdrawn isokinetically from the source and collected on a glass fiber filter maintained at a temperature of 120 ±14 °C (248 ±25 °F) or such other temperature as specified by an applicable subpart of the standards or approved by the Administrator for a particular application. The PM mass, which includes any material that condenses at or above the filtration temperature, is determined gravimetrically after the removal of uncombined water.
For more information about the IDEQ/EPA Method 5 visit: https://www.epa.gov/emc/method-5-particulate-matter-pm
Method 5 is also described within the UI Bison Engineering Report, "Determination of Particulate Emissions from Stationary Sources (Methods 2 & 4 Inclusive). The objective of Method 5 is to determine the filterable particulate matter (PM) from a source. Method 5 is an isokinetic sampling method (i.e., the velocity of sample stream entering the nozzle is approximately equal to the velocity of the approaching sample stream) for determination of PM. The exhaust gas stream is sampled along a cross-section of the stack and PM is captured within the nozzle, probe, filter-bell and on the 0.3 micron pore size glass fiber filter. The filter is maintained at a temperature of 248°F±25°F followed by impingers maintained at a temperature below 64°F. Bison uses a Method 5 sampling train with a stainless steel probe liner and nozzles to gather the particulate sample. Method 5 incorporates Method 2 "velocity measurements" and Method 4 "moisture measurements." Field data, spreadsheet calculations, example calculations, and pitot tube, probe alignment and thermal indicator calibrations are included in the report appendices”.

Air Pollutant Inventory:
The university measures air pollutant emissions from the wood fired boiler only as required by the Idaho Department of Environmental Quality as a Tier 1 emitter. Air pollutant emissions from natural gas or vehicle use are not inventoried, only carbon.
