Creating a statistical report about CO2 emissions in grams
Last updated: 15 June 2026
In this article
To calculate the estimated CO2 emissions from your transport operations, you can use the statistics report CO2 emissions.
About the statistical report CO2 emissions
The exact CO2 emissions for a single journey depend on actual fuel consumption and the specific type of fuel, what other goods were being transported at the same time, how much empty running the journey involved, and so on. It is difficult to obtain precise figures for these data, so standardised figures are used for fuel consumption and the CO₂ emission factor. The default values are selected so that the CO2 emissions data are reliable on average over time.
The statistical report is based on templates. To get it as accurate as possible, you need to find out your actual CO2 emissions, for example by totalling everything refuelled over a period of time. Then try out different factors on services until the sum in the statistics matches the reality and the allocation between different shipments is reasonable.
You can generate a statistical report showing the estimated CO2 emissions from transport over a given period. You can choose to generate the report:
-
Per vehicle
-
By customer
-
By service
-
By office (Known as Total in Opter 2025.06.00 and earlier.)
-
Overview (Available in Opter from 00:00 on 25 December 2025.)
The statistical report displays the following two columns for CO2 emissions:
-
Estimated (g) is an initial calculation of the order's CO2 emissions. The calculation is based on the information that is available at the time the customer places the order.
-
Calculated (g) is the calculated CO2 emissions for a shipment. 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.
For more information, see CO2 emissions, overview and This is how Opter calculates CO2 emissions.
Conditions
In order for Opter to calculate CO2 emissions, the following applies:
-
You must first configure the settings described in Settings for CO2 emission calculations.
-
There must be a space in the order. Further information on how to set a price limit on orders can be found in Distances, addresses and maps, overview.
Create a report about CO2 emissions
-
Click on Analysis > Statistics. Open CO2 emissions by clicking on
. -
Select the statistics you wish to view by clicking on Per vehicle, By customer, By service, By office or Overview. If you click on By office, the aggregated statistics for the office are shown.
-
Select Period at the top right of the window.
The date period is based on the order date on the order to which the shipments belong. Sometimes shipments are transported the day after the order date, but the order date is the most useful date for comparing with other statistics.
-
Click on Ok to create the statistical report.
For example, if you selected By customer, the estimated and calculated CO2 emissions for each customer for the period you selected are shown.
