This dissertation examines the options of regulating environmental due diligence for German and
European companies obliging them to verify compliance with environmental standards in their
supply chains. The thesis includes an investigation and systematization of the body of existing
norms for extraterritorial due diligence. Examples are the European Timber Trade Regulation
(EUTR) the Conflict Minerals Regulation the CSR Directive and the French Loi de Vigilance.
Finally the author analyzes environmental due diligence requirements in the new German Supply
Chain Due Diligence Act (LkSG). In addition other regulatory proposals are critically examined
and supplemented by the new considerations. The author also examines the compatibility of
existing and potential environmental due diligence requirements with higher-ranking law in
this case international law WTO law EU law and German constitutional law.
