In February 2022, the European Commission presented a Directive on Corporate Sustainability Due Diligence (CSDDD). The CSDDD is part of the broader transition of the European Union (EU) into a climate-neutral, resource-efficient and circular economy under the European Green Deal. The CSDDD seeks to integrate sustainability considerations into corporate governance in order to foster sustainable and responsible corporate behaviour. For the first time in the EU, cross-sector value chain compliance with human rights and environmental protection will become mandatory once the CSDDD enters into force. From 2024 onward, sustainability due diligence will play a more prominent role in corporate compliance and risk management. Companies will accordingly need appropriate counsel to help them navigate the corporate sustainability regulatory environment. Companies will have to set up new or update current due diligence mechanisms and map out and continuously monitor their value chains in order to satisfy the requirements of the CSDDD. The proposed text remains quite abstract as to how companies are expected to comply with the CSDDD. This article will provide a detailed summary of the scope and content of the proposal. Furthermore, it will present practical insights into how companies can best engage in value chain management under the CSDDD. Last, this article will raise an important yet overlooked practicality of the CSDDD: the due diligence collaborations that are expected from companies in the context of the CSDDD will likely raise intricate questions under the prohibition on anti-competitive agreements of EU competition policy. Likewise, the sharing of information in the context of the CSDDD may be equally problematic from the perspective of EU competition policy.
