At ICGN, we think that to produce reliable, comparable sustainable disclosures, the first key thing is that companies must be prepared to produce sustainability information, with strong governance, internal processes and controls for that. This is a crucial element to build trust for investors, but also to ensure that the information disclosed is verifiable, ready to be assured. Companies need to introduce rigorous processes to collect the data and document the information. There needs to be similar quality control as for traditional financial information. There must be Board oversight over this process and sign off of the results by the Board. Audit Committees should demonstrate competence for the oversight of sustainability and how this impacts the financial statements.
Once that reporting is prepared by the company, assurance is the next step. Sustainability reporting covers a broad range of very complex topics, so auditors and other assurance providers will need to build capacity and the necessary expertise to assure this information. An important part of sustainability data is based on estimates and/or dependent on other companies’ reporting. Some of the information is forward looking. Methodologies are still under development, and for some topics there is a lack of clear quantifiable metrics (e.g. human rights). This is a new and difficult territory for assurance providers. So, firms need to build the right capability, with appropriate training and resourcing.
