For free: automatic sumbarometer for 2 or more branches
Do you have multiple branches or locations and want to add up the same barometers every year for a total picture? Use the automatic sum barometer for this. If you have two or more barometers, you will receive a free automatic sum barometer included in your subscription.

One-time set-up and all will be added up automatically.
In the sumbarometer, you can select which barometers you want to combine. For every year in those source barometers the data are added up. If you make an adjustment in the source barometers, it is immediately reflected in the sum barometer too.
Same functionality as separate barometers
With the sumbarometer, you can do almost everything you’re used to doing with separate barometers. Such as:
- fine-tuning metrics
- adding goals
- creating graphs
- publishing CO₂ footprints
- printing reports
You cannot enter data into the sumbarometer, as input always comes from other barometers.
Example sumbarometer

The sumbarometer can also make sums of data that have modifiable titles and units (such as production size or items of Other CO₂ sources). If titles or units do not match, they will be combined (‘lunches’ + ‘meals’ becomes ‘lunches + meals’ in the sum).
The sumbarometer is now standard included in a subscription with two or more barometers.
A sumbarometer is included for free in your Envirometer subscription if you have more than one barometer. You can add even more sumbarometers (for example for specific regions), if you expand your subscription.
More information about the sumbarometer can be found in the HELP.

Yearly update CO₂‑factors february 2025
20- february-2025 The annual update of the CO₂ emission factors took place at the beginning of February 2025, on www.co2emissionsfactors.nl. All changes were implemented in the Envirometer on February 20. It is useful for Envirometer users to know the most important changes.

Factors for CO₂ and Energy in the Environmental Barometer Comply with CSRD
The reporting of greenhouse gas emissions and energy consumption in the Envirometer complies with the Greenhouse Gas (GHG) Protocol and the European Sustainability Reporting Standards (ESRS) requirements of the Corporate Sustainability Reporting Directive (CSRD). A key component is the calculation of Scope 2 emissions using two methods: the location-based and the market-based approach.

New Scope 3 Features
More and more organizations are being asked to map their Scope 3 emissions in addition to Scope 1 and 2. With the new features of the Envirometer, you can more accurately fill in Scope 3 and present the results according to the guidelines of the GHG Protocol, CSRD, and the CO₂ Performance Ladder.
