The symposium examines the EU Corporate Sustainability Due Diligence Directive (CSDDD), a major legislative adopted last year requiring companies to actively prevent rights violations and environmental harm throughout their supply chains. The Directive orders companies to identify risks and set up strong monitoring and accountability systems, transforming how companies interact with their stakeholders.
Legislation promoting supply chain accountability is becoming increasingly common. Within Europe, France, Germany, Hungary, the Netherlands, Norway, and Switzerland have already enacted due diligence and transparency laws, with Austria, Belgium, and Luxembourg currently debating similar proposals. This trend extends beyond Europe, with Australia, Canada, the UK, and the United States having laws focused on preventing forced labour and modern slavery.
Implementation challenges
The latest legislative proposals are facing an increased backlash, with large companies complaining of over-regulation and, in the case of smaller businesses, of existential threats. At the same time, national courts continue to invoke due diligence standards, yet ascribe to them varying degrees of substantive and procedural significance. To navigate these developments, León Castellanos-Jankiewicz, together with Tibisay Morgandi (Queen Mary University London) and Sergio Puig (European University Institute) curated the AJIL Unbound symposium addressing human rights, labour standards, climate change, and the environment. The texts cover the application of due diligence standards in domestic courts and new forms of liability under tools like the CSDDD. The essays were written by renowned experts and scholars Carsten Koenig, Humberto Cantú Rivera, Tibisay Morgandi, Jason Rudall, Jowita Mieszkowska and Sarah Vandenbroucke.
As 2025 marks a pivotal year for the transposition of this Directive, this publication is a must-read for academics, lawmakers, corporate leaders, and legal practitioners.

As large European companies face legal requirements to carry out sustainability due diligence, the question of how this new form of transnational governance is implemented has become more critical than ever. Many organisations are turning to digital solutions like AI, blockchain, data mining, and survey tools to embed sustainability into their operations and mitigate risks of adverse human rights or environmental impacts.
