Energi- og CO2-regnskabet

Web Solution Helps Municipalities with CO2 Emission Accounts

Reference: Realdania & the Danish Energy Agency

How does municipalities get an overview of their CO2 emmissions and energy consumption? With a user friendly web solution.

Viegand Maagøe has developed “Energi- og CO2-regnskabet”, which gathers data for the municipalities and conveys insights in a visual and intuitive way.

How we solve the task

The important first step for municipalities working with green transition is gaining insight into their energy consumption and CO2 emmisions. Viegand Maagøe developed Energi- og CO2-regnskabet to make this insight easy access.

For the project, we applied our combined competecies to a full extent. A combination of data, climate and communication experts participated in every phase of the project:

  1. Preliminary analysis
  2. Data preparation dokument
  3. Development pf the toolf
  4. Ongoing operation and data collection

First we analysed the individual needs in the municipalities using qualitative methods. Then we mapped data sources and in collaboration with the Energy Agency decided a method for the different emission sectors the solution had to cover.

Finally we developed the digital tool which was launched in the beginning of 2016. After launch
Viegand Maagøe has been responsible for operating and developing the service.

Energi- og CO2-regnskabet offers complete climate accounts. It saves municipalities the often exhaustive process of collecting data on municipal CO2 emmisions. The service gathers and processes vast ammounts of data and gives the municipalities insight and overview in a simple visual format.

Big data about CO2

To create the best possible web service we draw data from a number of different sources:

  • Tax administration (BBR)
  • Statistics Denmark
  • CVR
  • Banedanmark
  • DSB
  • Movia
  • Arriva
  • DCE
  • Danish Energy Agency
  • Energinet
  • The Danish Environmental Protection Agency
  • DTU Transport

Additionally, by applying the same method and data basis it is now possible to compare the data and results across the country.

As of 2019, 32 of Denmark’s 98 municipalities use the tool.

Global Goals

The project contributes to several of the 17 UN Global Goals:
