Supply Chain Due Diligence Act

On January 1, 2023, the German Supply Chain Due Diligence Act (LkSG) came into force. The law obliges the companies in the Stadtwerke Jena Group to comply with human rights due diligence obligations in their own business areas and throughout their entire supply chain. In order to meet this requirement, we take various measures. Here you will find all the important information.

Declaration of principles on human rights strategy

In connection with the entry into force of the Supply Chain Due Diligence Act (LkSG), Stadtwerke Jena GmbH adopted a declaration of principles on January 1, 2024. In this we anchor the management's declared goal of respecting, protecting and promoting human rights and the environment along the supply chain, but also in our own business areas. Violations of internationally anchored human rights and national and international environmental protection regulations will not be tolerated.
