The IFRS has also worked closely with EU advisory group EFRAG in developing the European Sustainability Reporting Standards ("ESRS"), being the standards that organisations in the scope of the EU's Corporate Sustainability Reporting Directive ("CSRD") will need to report. Some key differences in approach exist between the ISSB standards and the ESRS, though EFRAG acknowledged in response to the final publicatio n "the high level of interoperability reached on climate between ESRS and ISSB standards, therefore avoiding undue complexity for ESRS reporting entities and supporting the progress of a global baseline".
