CO2 emissions, overview

Last updated: 30 March 2026

Introduction

New in 2025.12.00:

  • If the distance is manually entered on the order, the shipment will automatically receive the same distance as you have entered on the order, if the following applies

    • The order has only one shipment.

    • The shipment does not have a manually specified distance.

    The calculated CO2 emissions of the shipment are then based on the manually entered distance on the order.

    (For Opter version 2025.06.00 and earlier, the CO2 emissions of the shipment are calculated based on the Opter/PTV distance, even if the distance is manually entered on the order and the order has only one shipment).

    For more information, see This is how Opter calculates CO2 emissions.

  • CO2 emissions from the subcontracting register.

    Previously, the CO2 emissions calculation was based on the price vehicle type if the shipment was subcontracted.

    You can now enter CO2 emissions data (e.g. fuel and fuel consumption) in the subcontractor register.

    If the shipment is subcontracted, the CO2 emission calculation is now based firstly on the subcontractor and secondly on the price vehicle type.

    For more information, see This is how Opter calculates CO2 emissions and Settings for CO2 emission calculations.

  • Estimated CO2 emissions (g) and Calculated CO2 emissions (g) are now displayed with two decimal places.

    (Previously Estimated CO2 emissions (g) and Calculated CO2 emissions (g) were only displayed in integers. For example, for orders with low weight and short distances that resulted in CO2 emissions of less than 1 gram, the CO2 emissions were displayed as "0". If you have many such orders, this becomes a bigger error over time).

  • If you work with consignments:

    The percentage, which shows the proportion of the consignment order's CO2 emissions that are charged to a specific original order, is now shown to two decimal places. (Previously, the percentage was shown only in whole numbers.)

    (The percentage is displayed on the shipment in the Order reception (under Detailid, on the tab General), if you hover over the field CO2 emissions, calculated (g).)

This is how you can see how much carbon dioxide (CO2) emissions your transport is estimated to have:

  • The CO2 emissions statistical report in Opter.

    You can manually produce a statistical report whenever you want and as often as you want. For more information, see Creating a statistical report about CO2 emissions in grams. The image below shows what it might look like if you chose to show the statistics per customer. More details are shown if you click on the customer's name.

  • Opter's statistics API.

    You can programme a solution where you call Opter's statistics API, retrieve the data you are interested in and then present the statistics as you wish. You can automate the flow so that the information is retrieved from Opter as often as you want. For more information, see Retrieve statistical data via API, CO2 emissions in grams.

Estimated and calculated CO2 emissions

Opter calculates the following values for CO2 emissions:

  • The order’s estimated CO2 emissions.

    The estimated CO2 emissions are an initial calculation of the CO2 emissions of the order and the calculation is based on the information available at the time the customer places the order.

    The image shows estimated CO2 emissions on the order page of the customer web.

  • The shipment’s calculated CO2 emissions.

    The calculated CO2 emissions for a shipment is a more accurate calculation than the estimated CO2 emissions for an order, as this calculation is also based on information about the actual vehicle and distance relating to the shipment.

  • The order’s calculated CO2 emissions.

    The calculated CO2 emissions of an order are a summation of the calculated CO2 emissions of the shipments in the order, and this is therefore a more accurate calculation than the estimated CO2 emissions of an order.

    The image shows the estimated and calculated CO2 emissions of the order reception.

For more information, see This is how Opter calculates CO2 emissions.

Conditions

For Opter to calculate CO2 emissions, the following applies:

  • You first need to make the settings described below, then you can produce CO2 emissions statistics as often as you like.

  • There must be a distance on the order. Further information on how to set a price limit on orders can be found in Distances, addresses and maps, overview.

Overview, settings in Opter

In order for Opter to be able to calculate CO2 emissions, the following settings and selections must be made first:

  1. Decide whether or not the pricing weight of the order compared to the capacity of the vehicle is to be taken into account.

  2. Decide whether you want to enter the CO2 emissions of the fuel in the fuel register, (so that you can then enter the fuel and fuel consumption of the vehicles, vehicle types and/or price vehicle types).

  3. Enter CO2 emissions for the Vehicles, Vehicle Types and Price Vehicle Types, either by entering the fuel and fuel consumption, or by entering the CO2 emissions (in g/km) directly in Opter.

  4. Decide whether you want to set the CO2 emission factor for some or all services, and possibly for some price vehicle types under the service.

  5. If you work with consignments, you can choose whether the calculated CO2 emissions of the consignment order should be distributed between the original orders, and if so, how the CO2 emissions should be distributed.

  6. If a subcontractor carries out the shipment, your Opter can obtain information on the CO2 emissions via EDI, the subcontractor register (in Opter 2025.12.00 and later), or the price vehicle type.

The settings are described in more detail in Settings for CO2 emission calculations.

Overview, CO2 emissions in Opter

CO2 emissions can be shown:

  • On the customer web.

  • On the invoice.

  • On the Freight bill.

  • In order reception.

  • In order check and shipment check.

  • In consignment check

  • In statistics.

How Opter calculates CO2 emissions

Read about how Opter calculates CO2 emissions for orders and shipments, what the CO2 calculations are based on, and the difference between estimated CO2 emissions and calculated CO2 emissions. See This is how Opter calculates CO2 emissions.

Step A: Settings for CO2 emission calculations

In order for Opter to calculate and display CO2 emissions, you must first make the settings described in Settings for CO2 emission calculations.

Step B: View CO2 emissions in Opter

Choose where you want CO2 emissions to be displayed in Opter, for example in the Order reception and the order check. See View CO2 emissions in Opter.

Step C: View CO2 emissions for customers and resources

Choose if and where you want to display CO2 emissions for customers and resources (e.g. drivers), for example on the customer web, invoice and/or on the Freight bill. See View CO2 emissions for customers and resources.

CO2 emissions via EDI

See CO2 emissions via EDI.

Recalculate CO2 emissions for orders

If you change any of the data on which the CO2 emissions calculations are based, you may subsequently have one or more orders for which you want the CO2 emissions to be recalculated. See Recalculate CO2 emissions for orders.

Create statistical report in Opter

You can manually pull a statistics report whenever you want. See Creating a statistical report about CO2 emissions in grams.

Retrieving statistical data via API

Using Opter's statistics API, you can see how much carbon dioxide (CO2) emissions your transport is estimated to have. See Retrieve statistical data via API, CO2 emissions in grams.
