In March 2021 the European Parliament urged the European Commission to submit a legislative proposal on corporate due diligence and accountability. The Commission is expected to do so this year. This paper argues that the intended introduction of a mandatory corporate due diligence standard into EU law is an evolutionary rather than revolutionary step in the process of making economic operators accountable for negative impact on people, environment or good governance. The elaboration of the supranational due diligence standard builds on the already existing legislative, soft law and judicial instruments within the EU. The paper attempts to outline possible outreach of the political compromise in the EP as well as that of the national debates and concludes by discussing how the emergence of national and supranational corporate due diligence standards will reshape the landscape for businesses active within the EU Internal Market.
