Designing EU Supply Chain Regulation

The EU Directive on Corporate Sustainable Due Diligence has sparked fierce debate about the regulations of supply chains. The Directive's objectives are aligned with European values. Assuming that enforcements of social and environmental rules are absent in certain third countries, it privatises compliance costs in complex supply networks. This paper suggests options to make the Directive more effective and efficient. It should exclude countries with a sufficient regulatory system and focus not on the entire network but on supplier-buyer relationships only. Public agencies should set harmonised regulatory standards, interpret the regulations and organise a private certification scheme in which liabilities are assumed by certification companies. The proposed system resembles the market for financial auditors.
