Transpas uses the integration with PTV Developer to calculate the emissions of trips.
The outcome of that calculation has been made clear per trip in the standard emissions report (no. 300).
However, many customers also find it interesting to have the emissions per shipment in Transpas.
A pop-up hint has been created.
The pop-up hint is on the Transport Orders screen, Shipments tab, Emissions column.
This hint consists of two parts: a brief summary of the emissions for the entire shipment and a detailed explanation. The explanation can be accessed from the summary.
We use the GLEC Framework for the units and standards of this emissions overview.
See this link for more information about this framework.
Emissions are shown with the following values:
All values are expressed in kilograms of CO2 equivalents (CO2e).
For clarity, the shipment used to retrieve the overview will hereafter be referred to as reporting shipment.
This summary is available in the shipment overview on the Transport Orders screen, under Emission.
The summary appears when you hover your mouse over the cloud icon in the field.
Here you see the allocated fuel consumption, the WTT, TTW, and WTW for the entire reporting shipment (point 1).
Clicking the question mark (?) icon displays the explanation (point 2).
The detail overview starts at the top with the same totals as the reporting shipment summary. Below, you'll find a specification of how these totals were calculated. Here's an example of the detail overview of the shipment whose summary is shown in section 2.
The overview is divided into:
These are explained below.
The overview contains this segment one or more times, depending on how often the reporting shipment was transferred via a cross-dock.
The trip segment shows a summary of the trip and also serves as a shortcut for navigating to the trip itself in the Planning screen (item 1).
The summary consists of the trip number, the start point, and the end point.
In addition, the trip also shows the portion of the trip emissions allocated to the reporting shipment, per emission value (item 2).
The trip trajectory segment is a section of the trip with a clear start and end point.
A trip can have multiple trajectories if a vehicle is changed somewhere or if the trip includes a crossing.
Like the trip segment, the trip trajectory segment shows the start and end points of the trip (point 1) and the portion of the emissions values assigned to the reporting shipment (point 2).
In addition, the trip distance and the shipment weight are also displayed (point 3).
The emissions overview begins with a reference to the truck used for this leg of the journey (point 1). This also serves as a shortcut to the truck itself.
Then the total emissions values for the journey are shown (point 2). These are not the emissions values for the reporting shipment.
This is followed by a list of all shipments currently in the vehicle (point 3). The reporting shipment is marked with a red asterisk (point 4).
For each shipment, the start and end points, the transport distance, and the shipment weight are shown (point 5).
Based on the distance and weight of the shipments, the transport activity is calculated per shipment in tonne-kilometers (point 6). 1 tonne-kilometer equals 1 tonne of cargo transported over 1 kilometer.
The emissions portion is calculated pro rata to the transport activity (point 7). Each shipment receives that portion of the total emissions of the vehicle combination.
The emission values for the traject are calculated by applying the percentage of the emission portion of the reported shipment to the total emission values of the vehicle combination.
The emissions overview for a crossing begins with the emission values (point 1).
This is followed by the specific crossing with a shortcut to the Crossings screen (point 2).
Here too, you have an overview of the shipments included in the crossing (point 3), with the reporting shipment marked with a red asterisk (point 4).
The calculation of crossing emissions works differently than that of vehicle combinations because it involves the assigned emissions of the crossing mode (a ferry or a train).
This calculation is therefore based on emission intensity and emission distance (points 6 and 7).
The weight to be transported is multiplied by the intensity and the distance and then converted to kilograms.
You can request the emission intensity and emission distance of a crossing from the companies offering these services.
These values can then be entered in the crossing screen.
For some crossings, the vehicle weight must be included in the calculation (point 5). The overview shows how much vehicle weight is included in the calculation and how that weight is allocated to the shipments.
This allocation is prorated to shipment weight.
Together with the shipment weight (point 8), this results in the emission values per shipment (point 9).
Vehicle weights can be entered for truck & trailer vehicles under "tare weight" and/or "empty weight". If empty or not available, enter it in the "empty weight" vehicle profile.
When shipments are outsourced in Transpas, this generally happens in two ways: with or without management. With outsourcing with management, the trip is still planned in Transpas.
However, for a shipment that is outsourced without management, the trip in Transpas does not reflect how the shipment was transported.
It is simply a list of shipments and/or shipment routes that were outsourced, without any insight into which shipments were transported together and by which vehicles.
The calculations described in sections 3.3 and 3.4 cannot therefore be performed.
Instead, intensity is used here, as with the crossing.
The overall overview (point 1) remains the same, as does the trip segment (point 2).
However, for the outsourced traject, only the TTW and WTW intensities are mentioned (point 3), and for the reported shipment, the shipment distance and weight are mentioned (point 4).
These values are used to calculate the WTT, TTW, and WTW values for the trip. There is no breakdown because Transpas uses the intensity to calculate the emission values per shipment instead of per trip.
