Summary: GRI Standards give organizations a structured way to measure and disclose ESG impacts in a format that is consistent, credible, and comparable. For supply chain and compliance teams, GRI Standards help translate sustainability goals into reportable data that supports CSRD alignment, investor expectations, and supplier oversight. Using GRI well improves transparency and makes ESG reporting more actionable across the value chain.
GRI Standards (Global Reporting Initiative Standards) are the world’s most widely used framework for sustainability reporting, enabling organisations to measure and disclose their environmental, social, and governance (ESG) impacts in a standardised, comparable format. In 2025–2026, GRI reporting has moved from voluntary best practice to a regulatory foundation: the EU Corporate Sustainability Reporting Directive (CSRD) requires large companies to report under the European Sustainability Reporting Standards (ESRS), which align closely with GRI Standards, while the EU Corporate Sustainability Due Diligence Directive (CSDDD) and Germany’s LkSG require the kind of documented supply chain impact data that GRI Standards are specifically designed to capture. According to a recent PwC ESG investor survey, almost 80 percent of investors consider ESG an important factor in investment decision-making, with 50 percent prepared to divest from companies without effective ESG policies. GRI standards collection and reporting is the systematic way to meet both investor expectations and regulatory requirements — here’s how.
What are GRI Standards?
According to the Global Reporting Initiative, “GRI Standards enable any organisation — large, small, private or public — to understand and report on their impacts on the economy, environment and people comparably and credibly, thereby increasing transparency on their contribution to sustainable development.” These standards are set by the Global Sustainability Standards Board (GSSB) and are updated regularly to reflect evolving regulatory and stakeholder expectations — most recently through the 2023 Universal Standards update and new Sector Standards releases. GRI reports help stakeholders effectively evaluate a company’s:
- economic performance and value chain impacts
- supply chain sustainability, including Scope 3 emissions and supplier social compliance
- customer privacy frameworks
- anti-corruption efforts
- work to improve occupational health and safety
- impact of their operations on local communities and human rights
In other words, GRI Standards offer a structured way for companies to collect, record, and share data about ESG initiatives with investors, policymakers, regulatory bodies, and civil society. This could include data on emissions, biodiversity, climate change, human rights, child labour, or forced labour in supply chains — all areas directly relevant to CSDDD and LkSG due diligence obligations. The GRI framework’s emphasis on supply chain transparency makes it a natural companion to the documented due diligence requirements of these regulations.
GRI Standards are subdivided into three broad categories: Universal Standards, Sector Standards, and Topic Standards. The Universal Standards — including the updated GRI 1 (Foundation 2021), GRI 2 (General Disclosures 2021), and GRI 3 (Material Topics 2021) — apply to all organisations and define the key principles of good ESG reporting, including accuracy, balance, and verifiability. Sector Standards focus on specific industries such as oil and gas, agriculture, or manufacturing, providing targeted guidance on material topics for those sectors. Topic Standards, such as GRI 303 (Water), GRI 305 (Emissions), and GRI 415 (Public Policy), address specific ESG issues including health and safety, waste management, human rights, and taxation.
These standards are modular, meaning organisations can use whichever combination of Universal, Sector, and Topic Standards best reflects their material impacts — while also aligning with CSRD double materiality assessment requirements, which mandate disclosure of both financial materiality and impact materiality across the value chain.
What are GRI Objectives and Targets?
The objective of GRI Standards data collection and reporting is to create a comprehensive sustainability report that provides stakeholders with credible, verifiable evidence of an organisation’s ESG performance and trajectory. By ensuring that data is collected in line with Universal, Sector, and Topic Standards guidelines, organisations can produce reports that are both accurate and independently verifiable — a requirement under CSRD, which mandates limited assurance of sustainability disclosures from 2025 and reasonable assurance from 2028.
GRI targets can be customised to meet company and regulatory needs. For example, a food processing organisation could apply Universal Standards alongside food-specific Sector Standards and detailed Topic Standards addressing food handling, protective equipment, cross-contamination, packaging, and supply chain traceability. Companies subject to the LkSG or CSDDD will typically need GRI Topic Standards covering human rights (GRI 406–412), labour practices, and environmental impacts to satisfy their due diligence documentation and annual reporting requirements.
When Should Companies Use GRI Standards Reporting?
GRI Standards reporting is appropriate — and increasingly mandatory — in several scenarios. First, companies subject to the EU CSRD must report on sustainability matters aligned with the European Sustainability Reporting Standards (ESRS), which draw directly from GRI Standards. Using GRI as the operational framework for data collection makes CSRD compliance significantly more manageable. Second, GRI reporting enables outside verification by investors, regulatory bodies, and procurement teams — rather than relying on self-declaration, GRI Standards provide the structured, verifiable disclosure format that institutional investors and regulators expect. Third, GRI reporting helps companies proactively identify ESG performance gaps. For example, a manufacturing firm’s GRI production reporting might show strong occupational safety performance while revealing supply chain emissions or waste management deficiencies that could trigger CSRD material topic requirements or LkSG risk flags.
How to Collect and Report GRI Standards Data
The GRI Standards data collection and reporting process has three key components:
- Identifying and assessing impacts
Organisations assess the significant positive and negative impacts of their operations and value chain on ESG factors, using both Universal and Sector Standards to create a comprehensive materiality picture. Under CSRD’s double materiality requirement, this assessment must consider both the impact of ESG factors on the business (financial materiality) and the impact of the business on people and the planet (impact materiality). This is also the foundation of the risk identification process required by LkSG and CSDDD.
- Determining the organisation’s material topics
Next, organisations must prioritise the topics most relevant to their ESG objectives, industry context, and stakeholder expectations, and decide which to include in their sustainability report. For supply chain-intensive businesses, material topics frequently include GRI 204 (Procurement Practices), GRI 308 (Supplier Environmental Assessment), and GRI 414 (Supplier Social Assessment) — the latter two directly supporting CSDDD and LkSG supplier due diligence documentation.
- Reporting disclosures
Organisations gather and disclose relevant information on ESG efforts, quantifying performance against targets and explaining management approaches for each material topic. Under CSRD, these disclosures must be included in the management report, accompanied by a GRI content index, and subject to third-party assurance. GRI reporting frameworks follow a standard format: reports must contain a GRI content index that provides an overview of the information collected, along with the applicable GRI Universal, Sector, and Topic Standard reference numbers. The report may be published electronically or in print and made accessible as a standalone document, part of a larger annual report, or on the company’s public website.

Before getting started with GRI data collection and reporting, it’s worth laying the groundwork with ISO 9001 quality management principles and ESG checklists. This structured self-assessment will identify which operations are performing as intended and surface areas of concern before the formal reporting process begins — reducing the risk of material misstatement and ensuring that disclosed data is accurate and defensible.
Frequently Asked Questions (FAQs)
Q: What are GRI Standards and who must use them?
A: GRI Standards are a voluntary international framework for sustainability reporting, developed by the Global Reporting Initiative and maintained by the Global Sustainability Standards Board (GSSB). While GRI itself remains voluntary, the EU Corporate Sustainability Reporting Directive (CSRD) requires large companies to report under the European Sustainability Reporting Standards (ESRS), which are closely aligned with GRI Standards. As a result, companies subject to CSRD effectively need to implement GRI-aligned data collection processes to meet their reporting obligations.
Q: How do GRI Standards relate to CSRD and CSDDD?
A: The EU CSRD requires sustainability reporting aligned with the European Sustainability Reporting Standards (ESRS), which draw heavily from GRI Standards — the two frameworks are designed to be interoperable. The EU CSDDD and Germany’s LkSG require documented due diligence across supply chains, generating the data on supplier social and environmental performance that GRI’s supply chain disclosure standards (GRI 308 and GRI 414) are specifically designed to report. Companies that implement GRI-aligned data collection as part of their CSRD compliance programme are simultaneously building the due diligence evidence base required by CSDDD and LkSG.
Q: What is the difference between GRI Universal Standards and Topic Standards?
A: GRI Universal Standards (GRI 1, 2, and 3 as updated in 2021) apply to all organisations and define foundational reporting principles, general disclosures, and the materiality assessment process. GRI Sector Standards provide guidance specific to high-impact industries such as oil and gas, mining, or agriculture. GRI Topic Standards (numbered GRI 200–400 series) address specific ESG issues — for example, GRI 305 covers emissions, GRI 403 covers occupational health and safety, and GRI 412 covers human rights assessments. Organisations select the combination of standards that best reflects their material impacts.
Q: How can Certainty Software support GRI data collection?
A: Certainty Software’s ESG assessment platform enables organisations to design and deploy structured data collection programmes aligned with GRI Topic Standards across multiple sites and supplier tiers. By digitising the assessment process, automating corrective action tracking, and generating real-time reporting dashboards, Certainty helps organisations build the systematic, auditable ESG data collection processes that GRI reporting — and CSRD, CSDDD, and LkSG compliance — requires.
