Scope
Mass PM2.5 emissions from the bus fleet per year in Helsinki Metropolitan Area (HMA).
The variable describes
Definition
Causality
List of parents:
- Emission factors
- Bus traffic intensity (number of bus trips? km travelled?)
- Travelling velocity
- Temperature (other weather factors? - would this be a weather variable, a temperature variable, or not a variable?)
- Engine type
- Fuel type
From paper model
- Bus km travelled
- Bus activity
- Relative emission factors
