CO₂‑footprint

CO₂ parameters in the Envirometer

Milieubarometer always calculates your CO₂ footprint using current CO₂ emission factors. This way you always have a reliable basis for your reports. Ideal as a user, so you don’t have to pay attention to it yourself.

The units are converted into CO₂ emissions using CO₂ emission factors. These CO₂ factors are determined and determined nationally. All CO₂ footprint reports therefore have the same scientific basis. The CO₂ emission factors are in line with the requirements of the CO₂ Performance Ladder and the GHG protocol.

List of current CO₂ factors

Would you like to know which factors the Environmental Barometer takes into account? The list of all current factors for this year can be found below. These values ​​are now used in the Environmental Barometer to calculate the CO₂ footprints.

Factors from previous years are also still in use. If you now calculate a CO₂ footprint for 2023, the CO₂ factors from 2023 will be used.

2014 << 2015 2016 2017 2018 2019 2020 2021 2022 2023 2024 >>

Expertise in emission factors

The list of emission factors is updated every year. This is done by a broad panel of experts in collaboration with the central government. The Stimular Foundation is part of this. Our advisors have thorough knowledge of CO₂ emissions and real conversion factors. This knowledge is reflected in the Environmental Barometer and all our advice.

When and how are the CO₂‑parameters changed?

In the list below you can find an overview of all changes:
