The Chief of Staff (CoS) is responsible for ensuring that sustainability reporting meets both the EU CSRD and Swedish law, such as the Annual Reporting Act. This means that the CoS must coordinate the collection and validation of sustainability data from different parts of the organization, ensure that the report covers all requirements and that it is reviewed by the board before publication. The CSRD places high demands on transparency, comparability, and the reporting of how the company works on environmental, social, and corporate governance issues. The CoS should establish clear processes and responsibilities for reporting, as well as use digital tools to facilitate data collection and analysis. It is also important that the CoS stays up to date on changes in legislation and adapts the reporting as needed. By working in a structured and inclusive manner, the CoS can ensure that sustainability reporting is both accurate and credible.
