In 2013, the city of Salzgitter drew up an integrated municipal climate protection concept and the following year the city council adopted it as a guideline for action. Since October 2015, climate protection manager Jan Holzenbecher has been organizing the implementation of the concept.
As part of this, the energy district concept for the area around Sonnenbergweg in Salzgitter-Gebhardshagen was initiated, which is funded by the Kreditanstalt für Wiederaufbau (KfW Bank) and the NBank.
