Since 1 January 2021, companies importing certain minerals into the EU must ensure that their sourcing practices do not contribute to conflict and human rights abuses. This ends the transitional period of the EU Conflict-Minerals Regulation published in 2017, which for the first time introduces binding human rights due diligence requirements for companies in the EU. However, the regulation’s scope is extremely limited. As such, its implementation can nonetheless be seen as a trial run from which lessons can be derived for the introduction of more comprehensive regulations in the extractive sector as well as for corporate due diligence in other sectors of the EU-economy.
