(51)The sustainability reporting standards should promote a more integrated view of all the information published by undertakings in the management report to provide users of that information with a better understanding of the development, performance, position and impact of the undertaking. The sustainability reporting standards should distinguish, as necessary, between information that undertakings should disclose when reporting at individual level and the information that undertakings should disclose when reporting at group level. The sustainability reporting standards should also contain guidance for undertakings on the process for identifying the sustainability information that should be included in the management report, since an undertaking should only be required to disclose the information relevant to understanding its impacts on sustainability matters, and the information relevant to understanding how sustainability matters affect its development, performance and position.
