Comparison infographics for ChargeYourYard.utah.gov and the 2-stroke rule were created using the following methodology, using NOx + Volatile Organic Compounds emission for an average 2019 model year passenger vehicle in the Northern Wasatch Front geographic area.
Emission Modeling System
- MOVES version: 3.0.4
- MOVES database: movesdb20220105
For Passenger Car:
- MOVES Onroad Default Scale
- Time Spans: 2019 Weekdays
- Geographic Bounds: Davis, Salt Lake, Tooele, Utah, and Weber
- On Road Vehicles: all passenger cars
- Road Type: all
- Pollutants: NOx + Volatile Organic Compounds
For Lawn & Garden 2-Stroke Equipment:
- MOVES Nonroad Default Scale
- Time Spans: 2019 all days, all months
- Geographic Bounds: Davis, Salt Lake, Tooele, Utah, and Weber
- Nonroad Equipments: gasoline all sectors
- Pollutants: NOx + Volatile Organic Compounds
Formulas Used
- Emission Factor (g/mile per vehicle)=(Emission gram)/(Vehicle Mile Traveled)
- Equivalent miles per vehicle=(gram per hour per machine)/(gram per mile per vehicle)
