This benchmarking study captures and analyzes the extent to which companies are reporting and obtaining assurance over their sustainability disclosures, which assurance standards are being used, and which companies are providing the assurance service. 

For the fourth consecutive year, our State of Play analysis indicates that while the frequency of reporting ESG information is very high and the incidence of assurance is on an upward trend, there continues to be a meaningful difference between reporting and assurance rates.
