CSRD and ISSB interoperability
Nowadays, it's almost impossible to open a newspaper without encountering an article on 'sustainability'. Whether it's in the context of the financial services industry, the broader economy, or society as a whole, sustainability has become a critical issue. In recent years, it has gained significant traction and is now recognised as a necessity rather than just a trend.
Over the past decade, the focus on environmental issues has grown exponentially, resulting in various global commitments and initiatives aimed at transforming current institutional, economic, and financial models.
This training focuses on the interoperability between the Corporate Sustainability Reporting Directive (CSRD) and the International Sustainability Standards Board (ISSB) frameworks. Participants will gain a comprehensive understanding of how these two major sustainability reporting standards align, overlap, and complement each other, allowing organisations to efficiently meet their regulatory requirements while delivering meaningful sustainability disclosures to a wide audience. The aim is to reduce duplication, promote transparency, and maximise the utility of disclosed sustainability data.
