What Is GRI Reporting?
GRI reporting refers to sustainability reporting prepared using the standards developed by the Global Reporting Initiative. These standards help organisations disclose their impacts on the economy, environment and people in a structured and comparable way, rather than relying on broad sustainability statements alone.
The Global Reporting Initiative (GRI) is an independent, nonprofit international organisation founded in 1997. It develops one of the world’s most widely used frameworks for sustainability reporting, used by companies, public bodies and other organisations across different industries and markets.
Understanding what is GRI reporting starts with the GRI Universal Standards. These form the baseline that every organisation applies before reporting on specific topics. According to GRI’s own 2024 data, GRI is used by more than 14,000 organisations in over 100 countries, making it one of the most widely adopted sustainability reporting frameworks globally. For businesses in Singapore, this makes GRI a useful reference point for preparing clearer, more consistent and more credible sustainability disclosures.
What is the Purpose of the GRI Universal Standards?
The first purpose is to establish a strong reporting foundation. These Standards provide a shared baseline for organisations using GRI, helping to standardise structure, terminology and reporting expectations. This allows stakeholders to compare reports more meaningfully across industries, regions and markets.
The second purpose is to shift sustainability reporting towards impact and accountability. The Universal Standards emphasise actual and potential impacts rather than broad claims or general sustainability intentions. This encourages organisations to explain not only what they are doing, but why it matters, who is affected and how these impacts are managed.
For Singapore businesses, this is particularly relevant as sustainability expectations continue to mature. According to the 2024 KPMG Survey of Sustainability Reporting, Singapore has one of the highest GRI adoption rates among leading companies worldwide, at 97%, second only to Taiwan globally. This shows how widely GRI is already used among leading local companies and why stronger governance, clearer materiality assessments and more reliable disclosures matter.
Understanding GRI 1, GRI 2, and GRI 3
GRI 1: Foundation
GRI 1 sets out the core principles and requirements for using the GRI Standards. It explains key reporting concepts such as impact, materiality, due diligence, and the requirements an organisation must comply with to report in accordance with the GRI Standards.
In practice, GRI 1 serves as the starting point. It helps organisations understand how the Standards fit together and what is expected before they begin selecting disclosures. It also clarifies what it means to report “in accordance” with GRI, which is important for avoiding unclear or overstated claims.
GRI 1 matters because it creates discipline in the reporting process. Organisations need to be transparent about their reporting decisions, including the information they disclose, the topics they prioritise, and any limitations or omissions. This improves the credibility and defensibility of the final sustainability report.
Additionally, GRI 1 provides a useful reference point for sustainability reporting. It helps organisations align their reporting process with broader governance and accountability expectations.
GRI 2: General Disclosures
GRI 2 focuses on general disclosures that help stakeholders understand the organisation behind the report. These include the organisation’s profile, activities, value chain, governance structure, strategy, policies, stakeholder engagement, and ethical practices.
This section is important because sustainability performance cannot be properly understood without context. A company’s impacts are closely linked to where it operates, how it is governed, the nature of its value chain, and how it engages stakeholders.
GRI 2 helps create consistency in this background information, making it easier for readers to understand who the organisation is and how it operates. It also connects sustainability reporting to leadership, governance, and decision-making, rather than treating it as a separate corporate exercise.
For example, stakeholders may want to know who oversees sustainability matters, how policies are implemented, and how concerns are escalated within the organisation. By requiring these disclosures, GRI 2 enhances transparency and improves comparability across sustainability reports.
GRI 3: Material Topics
GRI 3 guides organisations in identifying and prioritising material topics. Under this Standard, material topics are those that represent the organisation’s most significant impacts on the economy, environment, and people. GRI 3 also requires organisations to explain their process for determining material topics and how each material topic is managed.
This is one of the most important parts of the Universal Standards because it shifts reporting away from selective disclosure. Instead of reporting only topics that look favourable or are easy to communicate, organisations are expected to focus on issues that have the greatest impact.
GRI 3 strengthens the credibility of materiality assessments by requiring a clearer link between reported topics and actual business impacts. This helps reduce marketing-driven reporting and improves the usefulness of sustainability information for stakeholders.
This matters for businesses when sustainability reporting involves multiple stakeholder groups, regional supply chains, or sector-specific ESG risks. A stronger materiality process helps ensure that the report addresses what genuinely matters, not only what is convenient to disclose.
How the GRI Universal Standards Work Together
The Standards are designed as a modular and integrated system. GRI 1 provides the foundation and reporting principles. GRI 2 sets out the organisation’s general context, including governance and stakeholder engagement. GRI 3 determines which ESG topics are material and should be reported in more detail.
Once the organisation has identified its material topics through GRI 3, it can then use the relevant GRI Topic Standards to report specific information about those impacts. GRI Sector Standards may also apply where sector-specific guidance is available. The GRI Standards are structured into Universal, Sector, and Topic Standards that work together as an interrelated reporting system.
This integrated structure supports more future-ready reporting. As regulations, investor expectations, and stakeholder scrutiny continue to evolve, businesses that follow a clear GRI-based process are better positioned to produce consistent and assurance-ready reports.
In this context, professional assurance services help organisations review whether sustainability information is supported, consistent, and aligned with the selected reporting criteria. They can also help management identify reporting gaps before the sustainability report is published.
Why the GRI Universal Standards Matter for Organisations
The Standards support more credible and consistent sustainability reporting. They help organisations replace general ESG claims with structured disclosures that show how impacts are identified, governed, and managed.
- For investors and regulators, this improves transparency.
- For customers and business partners, it supports greater confidence in the organisation’s sustainability commitments.
- For internal teams, it provides a clearer process for gathering data, assessing material topics, and improving reporting practices over time.
Adopting the GRI framework can help organisations build a more disciplined and structured reporting process. It also prepares them for closer review, especially when sustainability disclosures are used for financing, stakeholder engagement, procurement, or regulatory communication.
Building More Credible Sustainability Reports
The GRI Universal Standards provide a practical and globally recognised foundation for sustainability reporting. With GRI adoption already widespread among Singapore’s leading companies, the differentiator for most businesses is not only whether they report, but how credible that reporting is.
Credible GRI reporting depends on more than selecting the right framework. Organisations need sound reporting processes, clear data ownership, documented assumptions and appropriate review before disclosures are published. When supported by sustainability report assurance, the GRI framework can help companies communicate with greater confidence, transparency and accountability.
