How to use the tool:

1. Select the desired output (final energy demand OR CO₂ emission).

2. Select the sector, end use and energy carrier. For these parts, you can choose more than one option. Depending on the selected combination of sector and end use, different set of energy carriers might be shown.

3. Select the desired scenario (Scenario A, Scenario B or Scenario C). The scenarios A and C represent two rather extreme development options and Scenario B represents a hybrid variant between the two extreme scenarios A and C. To read more about the scenarios and the underlying assumption here .

4. The graphic on the right side shows the results of only one selected scenario. On this graphic, you can compare the results between the scenarios and/or between the years. Be aware that depending on the combination selected, the color scale could change. The graph on the bottom shows the comparison between 3 scenarios.

5. You can also download the results of the selected combination by clicking on Download.

The scenarios were developed based on the current situation and the policies in place at the time of scenario development. It is shown that even with the most optimistic scenario the climate neutrality of the German building stock may not be reached by 2045. To reach the climate-neutrality further measures will be necessary. This is investigated in future publications from the project.
