For explanations of the data and the various exports, please consult the methodological note.

There are several factors that can influence CO2 emissions. 

Those related to your activity:

• Package characteristics (weight and volume) 
• The distance of the parcel's journey (depending on your injection points and the destination of your parcels).

Those relating to Colissimo's activity:

• Actions to green transport and the last mile (use of low-carbon energies through biogas, biofuel and electricity)
• Actions to optimize logistics links (improving fill rates, setting up logistics HUBs) 

Those relating to the adaptation of the calculation methodology: between this new version of the October 2024 CO2 calculator and the previous version, the methodology has evolved to comply with Smart Freight Center criteria.

To find out more, consult the methodological notice.

The calculation method of the new version of the calculator takes into account the following elements, in accordance with the GLEC framework accreditation:

• Increased distances to take account of distances travelled empty
• New ADEME and GLEC emission factors certified by the GLEC framework
• Change in the calculation of “Other” emissions, which now include emissions from logistics sites. Emissions linked to business travel and data centers have been removed, as they do not fall within the GLEC perimeter.

The tonne-kilometer is a unit of measurement used in the transport sector to quantify the volume of goods transported. It corresponds to the transport of one tonne of goods over a distance of one kilometer. 
It is used as a tracking indicator and can be used to calculate carbon emissions.

We recommend using grams of CO2 per parcel. This figure is more representative of carbon performance in the context of a single-package activity vs. the tonne-kilometer.

The information provided by the CO2 calculator meets a specific use case for monitoring the CO2 emissions of the flows you entrust to us. To inform a consumer of the CO2 emissions of a delivery method, it is necessary to use a calculation methodology that is comparable between different delivery methods. The French Ministry of Ecological Transition, Ademe, e-tailers, consumer associations, La Poste and carriers have worked to define a reliable and comparable standard for measuring CO2 emissions for consumer communication purposes. So if you want to display CO2 information on the delivery methods you offer your customers, you must not use information from the CO2 calculator, but refer to the experimental standard NF XP 50-401. Colissimo will provide the information you need during 2025.

In the meantime, you can raise your customers' awareness of the environmental impact of their delivery by using the Colissimo Ecological Score.
