CSRD & CSDDD: Turning EU Compliance into Supply Chain Transparency

What are they key differences between the  Corporate Sustainability Reporting Directive (CSRD) and Corporate Sustainability Due Diligence Directive (referred to as CSDDD or CS3D) and how is ESCP supporting its members to comply?

August 29, 2025

In May 2024, the EU Council gave its final approval on two sustainability directives: the Corporate Sustainability Reporting Directive (CSRD) and Corporate Sustainability Due Diligence Directive (referred to as CSDDD or CS3D) as part of the European Green Deal.

While they differ in focus, CSRD demanding transparent reporting and CSDDD requiring active due diligence, together they create a framework that integrates sustainability into corporate governance and supply chains.

These directives represent both challenges in the short term and opportunities in the long-term for businesses. As soon as they were drafted, members of the Ethical Supply Chain Program (ESCP), were immediately able to begin building their frameworks benefiting from the program’s trusted grievance mechanism, easy-to-access Connect platform data and expert on-the-ground support.

In the long-term, both the CSRD & CSDDD give organisations operating globally a clear framework and guidance to become climate-neutral by 2050 and enable a just transition, as well as enhancing visibility of the entire value chain.


CSRD vs. CSDDD: In Brief


CSRD – Corporate Sustainability Reporting Directive

  • Requires companies to report sustainability data alongside financials
  • Based on double materiality: how sustainability issues affect the company and how the company impacts society and the environment
  • Reports must comply with European Sustainability Reporting Standards (ESRS) and be submitted digitally to the European Single Access Point (ESAP)
  • Phased rollout from 2024–2027

CSDDD – Corporate Sustainability Due Diligence Directive

  • Obligates companies to identify, prevent, mitigate, and remedy adverse impacts on human rights and the environment
  • Focused on the chain of activities (suppliers, operations, downstream partners)
  • Requires companies to establish and maintain effective grievance mechanisms
  • Requires a climate transition plan and regular public reporting
  • Applies first to very large companies (≥1,000 employees / €450m turnover), with phased adoption through 2027–2028

Both are important for businesses operating with global supply chains. The CSRD provides the framework and transparency to disclose ESG risks and performance. The CSDDD ensures companies act on risks in their value chains, not just report them. Information for both will need to be submitted via the European Single Access Point (ESAP).

Together, they bring all suppliers, not only tier 1, into the spotlight. For businesses operating globally, this means that data collection, supplier engagement, and risk management are no longer optional, but legal imperatives.

How the Ethical Supply Chain Program (ESCP) is Supporting Compliance with CSRD & CSDDD

Effective Grievance Mechanism – ESCP Helpline Service

The CSDDD requires companies to establish and maintain effective grievance mechanisms, with timelines starting as soon as 2027. There has been much discussion around how the EU qualifies ‘effective’, but to us, this means a trusted service that supports root cause identification and improves the lives of workers.

ESCP has operated a confidential grievance mechanism service for supply chain workers since 2010, providing access to over 10 million workers.

The ESCP Worker Helpline is supported by Helpline Analytics which enable businesses to export the required data, understand the situation on the ground in their supply chain while providing a vital support system for workers.

ESG Data for Reporting – ESCP Connect Platform

Both frameworks require businesses to understand their impact on society and the environment, and you cannot begin to know what you don’t measure. ESCP’s Connect Platform enables program members to not only track key ESG metrics, but monitor and measure performance over time. This data granularity enables businesses to identify high risk areas, the root cause of issues and build a roadmap for improvement.

Unlike audit-only programs, ESCP provides remediation support, ensuring no outstanding non-compliances and clear evidence of remedying adverse impacts on human rights.


Ongoing Support – ESCP Expert Team

The CSRD & CSDDD represent significant change in processes for many businesses, ESCP’s expert team are there to ensure the transition to greater transparency is as smooth as possible for new member organisations.

The ESCP team are located all over the world and can help businesses build capacity to remedy issues found on audit, find new suppliers within the ESCP program, as well as communicating with existing suppliers to explain reporting requirements and the future of manufacturing.

The ESCP Worker Helpline was developed for workers in manufacturing setting but is now adopted across multiple industries such as construction.
