Both internal and external assurances improve the quality of information.  Internal controls, internal audits, independent third party reviews, and third party commentaries all help to make information more credible and therefore more useful to the reader. Thus, everyone benefits.  Assurance methods can do the following:
  • enhance the readers’, and the organization’s own, confidence about sustainability information
  • lead to better decisions or judgements about performance.
  • allow others, not involved in the preparation of the report, to provide valuable ideas on the interpretation and analysis of the report indicators
  • provide the impetus to improve sustainability performance.
