As sustainability reporting continues to evolve, organisations are under increasing pressure to produce information that is not only accurate, but also meaningful, transparent and comparable. But what does comparability really mean, and why is it such an important principle in sustainability assurance?
In this thought-provoking article, IRAS Managing Partner Michael H Rea explores the origins of the Global Reporting Initiative (GRI) and explains how the principle of comparability has become fundamental to credible ESG reporting.

The article also unpacks the distinction between verification and assurance, highlighting why sustainability data must be tested for far more than accuracy alone. Concepts such as materiality, completeness, consistency and reliability all play a critical role in producing reports that stakeholders can trust.
