Mobility

• Distance calculations
• Transportation modes

Business Trips

The calculation of emissions from business trips is currently supported for the following modes of transport:

• car

• bus

• train

• plane

• ferry

The user must specify either the distance of a trip or the location of departure and destination. The distance (in km) may be used, when the user has the direct information of the distance travelled, e.g., from the speedometer of a car. In other cases, the distance can be calculated from the given locations, see Distance calculations. With the boolean paramter roundtrip, users can indicate whether a trip was a roundtrip, in which case the distance wil be doubled.

Aside of the mode of transport, the user should provide the specifica of the trip, depending on the mode of transport (see :doc’Transportation modes <calculate/transport_modes>’ Emission factors).

Commuting

The calculation of emissions from commuting is currently supported for the following modes of transport:

• car

• bus

• train

• motorbike

• tram

• bicycle

• pedelec

Their specific emission factors for different configurations (e.g., vehicle size, fuel type, etc.) are documented under Emission factors.

For each mode of transport used for the commute, the user must provide the average weekly_distance (in km) travelled during a given time period. The users are asked to enter their usual commuting behaviour and should estimate the distance as accurately as possible. If they often use a different mode of transport if there is bad weather or in the cold season, they should account for this by estimating the mean distance for each transportation mode over the entire year. The commuting data may also be entered separately for each month or once for the summer months and for the winter months (e.g., April-October and November-March).

Aside of the mode of transport and the weekly distance, the user should provide the specifica of the commute, depending on the mode of transport (see Emission factors).

Car commute

The quantity of CO2e emitted by a car commute depends on the fuel_type (average, cng, diesel, electric, gasoline, hybrid, hydrogen, plug-in_hybrid), car size (average, small, medium, large) and the number of passengers.

Bus commute

The quantity of CO2e emitted by a bus commute depends on the fuel_type (cng, diesel) and bus size (average, small, medium, large). The vehicle_range is set to local automatically.

Motorbike commute

The quantity of CO2e emitted by a motorbike commute depends on the size (average, small, medium, large) of the motorbike.

Train, tram, bicycle or pedelec commute

For train, tram, bicylce or pedelec, no specifica have to be provided.
