Assurance is far more than a box-ticking exercise. The 2020 EY Climate Change and Sustainability Services (CCaSS) Institutional Investor survey showed that as investors scrutinise ESG data, and do so more formally, assurance will be increasingly driven by the demand for credible data. A good assurance provider will look beyond the data, to the accuracy and completeness of the disclosures that bring context and meaning to the data. They can also bring an independent perspective to overly positive spin, questions of materiality or lack of engagement with the data.
The key issue in Australia is that, because assurance is not mandated, it's not standardised. And because companies determine the scope of assurance, it can vary widely. Partial assurance of ESG reports remains common and can be confusing to the end reader as well as limiting the level and depth of external challenge.
Assurance is no panacea, but it can be a good lever for change. EY has found that strong relationships with assurance providers allow those challenges to be heard among the C-suite cacophony.
Standards response
There is not yet consensus on a global standard for sustainability reporting. There are, however, a number of well recognised frameworks that support reporting maturity.
The assessment found that over half of the ASX200 are reporting against GRI (107 reporting) and the Taskforce on Climate-related Financial Disclosure (108) frameworks, with a smaller but growing number using the Sustainability Accounting Standards Board (27) and <IR> (11) frameworks. SASB and the International Integrated Reporting Council have recently merged to form the Value Reporting Foundation, and our expectation is that this combined framework will see far more application in the coming years.
The data shows that ESG reports employing at least one framework, or more than one in combination, have consistently higher maturity scores. The assessment found that the use of frameworks dramatically increases maturity, with companies using at least one framework having an average maturity score of 3.01 compared to a score of 1.46 for those that don’t.
Targets and SDGs
EY is also seeing more leading-edge organisations refreshing their strategies to include impact-based targets linked to frameworks such as the UN Sustainable Development Goals (SDGs) and Net Zero. These are in addition to the well-established targets around diversity, particularly gender balance and leadership, and health and safety.
We are seeing increasing alignment to the SDGs. In 2020, 103 companies aligned with the SDGs, compared with 90 in 2019 and 45 in 2018.
