The Corporate Sustainability Reporting Directive (CSRD), originally adopted by the European Union in 2022, marked a landmark shift in corporate sustainability disclosure regulation. The intended developments regarding the scope of companies affected, the reference to the future European Sustainability Reporting Standards (ESRS) covering environmental, social and governance (ESG) topics, or the adoption of third-party assurance highlight central examples of how the CSRD was aimed at enhancing transparency, comparability, and accountability in corporate sustainability disclosure practices. At the same time, these changes also created considerable challenges for companies, assurance providers, and users.
In 2025, the European Union (EU) initiated an "Omnibus" package proposing amendments to the CSRD and the related Corporate Sustainability Due Diligence Directive (CSDDD), Carbon Adjustment Mechanism (CBAM) as well as a draft Taxonomy Delegated Act. These proposed amendments target, amongst others, to simplify the scope of companies affected, the reporting requirements, and the third-party assurance requirements. The Omnibus amendments aim at reducing the administrative burden for companies and maintaining their competitiveness. However, the ad hoc and short-term character of this process increased policy uncertainty and also led to criticism, not only because many companies had already started to prepare for the original CSRD and the related ESRS, but also because the planned reduction in the scope and the simplification of ESRS were perceived by some stakeholders as a threat that could undermine the leadership of the EU in sustainability practices and reporting.
This Special Issue invites manuscripts that explore various impacts of the CSRD on companies such as changes in corporate behaviour, internal processes, management systems, strategy formulation, or business models. Accordingly, the special issue welcomes original normative research that examines the original CSRD's provisions or the (expected) changes due to the Omnibus process. The issue also seeks research on the broader regulatory, institutional, and political dynamics shaping the development and adoption of the EU's sustainability disclosure regulation. Researchers are encouraged to focus on specific challenges of CSRD adoption before and after Omnibus as well as insights outside of the CSRD which have implications for its implementation.
