IFAC: Sustainability Reporting and Assurance Practices of Largest Global Companies Continue to Mature, IFAC, AICPA & CIMA Study Shows

23 February 2024

98% of companies reported some level of detail on sustainability; 69% obtained assurance on at least some of their sustainability disclosures; The mix of reporting standards used by companies remains fragmented

The largest global companies are providing more detail and breadth in their sustainability reporting, and also are obtaining a greater scope of assurance on those disclosures, according to an updated report from the International Federation of Accountants (IFAC) and AICPA & CIMA. The study, an annual benchmark that now includes 2022 data, also found the use of varying sustainability standards and frameworks continues to make it difficult for investors, lenders, and other stakeholders to find consistent and comparable sustainability information.

While progress is being made, the report, The State of Play: Sustainability Disclosure and Assurance 2019-2022, Trends and Analysis, highlights the need for companies worldwide to move toward a global system of sustainability disclosure requirements. On a positive note, the study found over half of companies use the Sustainability Accounting Standards Board (SASB) Standards and the Task Force on Climate-related Financial Disclosures (TCFD) Framework, which should ease the transition to the International Sustainability Standards Board (ISSB) standards, which were released last year.

“While we’re moving toward commonly accepted global standards, some 87% of companies continued to use a mix of standards and frameworks for reporting,” said David Madon, IFAC’s director of sustainability, policy and regulatory affairs. “That leaves investors and lenders in a bind when it comes to having consistent, comparable and high-quality sustainability information at hand.”

Among the highlights of the updated study:

• Almost all companies (98%) report some information on sustainability. That’s an increase from 91% in 2019, when IFAC and AICPA & CIMA first began conducting research in this area.
• Use of standalone sustainability reports has declined by 27 percentage points in the past three years. Only 30% of companies used a standalone sustainability report in 2022, reflecting the growing inclusion of that information in companies’ annual or integrated reports.
• 69% of companies obtained assurance on at least some of their sustainability disclosures, up five percentage points from last year and 18 percentage points from 2019. The scope of assurance areas also expanded, yet still remains limited in general.
• Accountancy firms (as opposed to consultants or other service providers) handled 58% of the assurance engagements related to sustainability in 2022, a percentage point better than the previous year.  Some markets, notably the United States, fall well below 50%.
