Does the institution have policies and/or guidelines in place to improve outdoor air quality and minimize air pollutant emissions from mobile sources?:

A brief description of the policies and/or guidelines to improve outdoor air quality and minimize air pollutant emissions from mobile sources:

Has the institution completed an inventory of significant air emissions from stationary sources on campus?:

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

The University calculates its annual pollutant emissions and reports them to the New Jersey Department of Environmental Protection, as is required by the University’s Title V permit. Techniques include calculation methods with AP-42, continuous emission monitors, and fuel use records from the various sources over the calendar year.

Weight of the following categories of air emissions from stationary sources::
Weight of Emissions
Nitrogen oxides (NOx) 59.01 Tons
Sulfur oxides (SOx) 3.51 Tons
Carbon monoxide (CO) 72.16 Tons
Particulate matter (PM) 8.34 Tons
Ozone (O3) ---
Lead (Pb) 0 Tons
Hazardous air pollutants (HAPs) 76,705.13 Tons
Ozone-depleting compounds (ODCs) 0 Tons
Other standard categories of air emissions identified in permits and/or regulations 22.44 Tons

A brief description of the institution’s initiatives to minimize air pollutant emissions from stationary sources, including efforts made during the previous three years:

The University is committed to reducing air pollutant emissions through campus infrastructural improvements. These improvements include:
-Thermal distribution system improvements
-Lighting upgrades, including retrofitting most of campus lighting with LED bulbs
-Building HVAC replacements
-Existing building energy conservation projects
-Plant efficiency and run-time improvements
-Installing a 5.4 MW solar field to produce electricity
-Control system optimization

Although Princeton doesn't have a formal policy to improve outdoor air quality and minimize air pollutant emissions from mobile sources, Princeton still has a strong commitment to clean air. The TigerTransit bus fleet runs on biodiesel fuel, campus fleet vehicles include electric carts, and newer facilities vehicles are fuel-efficient.
