What are GRI Standards

GRI Standards are an international framework developed by the Global Reporting Initiative that enables organizations to report transparently on their environmental, social, and governance impacts.

Unlike mandatory regulations, GRI was created as a voluntary system. However, over time it has become a de facto standard for sustainability reporting, used by thousands of companies worldwide.

Its main objective is to provide a common language for communicating ESG performance, allowing stakeholders (such as investors, clients, and institutions) to better understand, compare, and evaluate data across companies and even across different countries.

What type of reporting does GRI focus on

One of the most distinctive aspects of the GRI framework is its impact-based approach.

GRI Standards primarily focus on one key question:
what is the company’s impact on the environment and society?

This means that GRI emphasizes a perspective centered on the effects of business activities on issues such as climate change, resource use, human rights, and working conditions.

This approach is particularly useful for building a credible sustainability report, as it allows companies to clearly communicate their real contribution within the context in which they operate.

In this sense, many companies use sustainability reporting software to collect and organize data according to standards like GRI.

GRI and materiality: a different approach from European regulation

A key element in understanding the role of GRI today is its comparison with the concept of double materiality introduced by European regulation.

In GRI, materiality is primarily linked to the company’s impact on the external environment.
With CSRD, however, companies must also consider the opposite perspective: how ESG factors affect financial performance.

GRI → company impact on environment and society
CSRD → double materiality (impact + financial risk/opportunity)

For this reason, many companies today use GRI as a methodological foundation, integrating it with more advanced regulatory requirements.

How the GRI framework works in practice

The GRI framework is modular and flexible, allowing companies to adapt reporting to their specific operational context.

At its core, the GRI model is structured around universal standards, topic-specific standards, and, in some cases, sector standards. Universal standards define reporting principles and organizational context, while topic-specific standards guide the measurement and disclosure of the most relevant ESG impacts.

The process begins with the identification of material topics—those ESG aspects that represent the most significant impacts for the company and its stakeholders. This phase is crucial, as it determines which information must be collected and reported.

Once material topics are defined, GRI requires companies to translate their activities into measurable data through specific disclosures. In practice, GRI Standards enable organizations to monitor a wide range of variables, including:

• greenhouse gas emissions and energy consumption

• use of natural resources such as water and raw materials

• waste management and lifecycle environmental impacts

• working conditions, health, and employee safety

• diversity, inclusion, and human rights

• governance practices and ethical behavior

These variables are not analyzed in isolation but always in relation to the impact generated by the company. The goal is not only to measure internal performance, but to understand how business activities influence the broader environmental and social context.

A key aspect is that GRI does not impose a fixed set of indicators for all companies. Instead, it requires organizations to justify their choices, ensuring consistency, transparency, and data traceability over time.

This approach prevents superficial or purely descriptive reporting. The result is a report that not only communicates information but helps identify where the company generates impact, what the priorities are, and where there are concrete opportunities for improvement.

Does it still make sense to structure a sustainability report using GRI?

Despite regulatory developments, GRI reporting remains highly relevant.

First of all, it is a global standard. While regulations like CSRD are specific to Europe, GRI is used internationally, making it particularly valuable for companies with a global presence.

Moreover, GRI often serves as the starting point for structuring ESG data. Even when companies need to comply with more complex standards, the GRI framework provides an already organized foundation.

Finally, GRI maintains strong credibility among stakeholders and investors, thanks to its widespread adoption and long-standing history.

GRI – ESRS – VSME

As ESG reporting evolves, many companies find themselves navigating multiple frameworks: GRI, ESRS, and VSME. Rather than being alternatives, these standards address different needs and can be used in a complementary way.

ESRS represent the mandatory European standard for companies subject to CSRD. They are designed to ensure a high level of transparency, comparability, and compliance, introducing structured requirements and the principle of double materiality.

GRI, on the other hand, remains a voluntary and global framework focused on the company’s impact on the environment and society. For this reason, it is often used as a methodological foundation for ESG reporting, even by companies that later need to align with ESRS.

VSME (Voluntary Sustainability Reporting Standard for SMEs) fit into this landscape as a simplified standard designed for small and medium-sized enterprises. They respond to a practical need: enabling companies not subject to regulatory obligations to structure their ESG data in a consistent and market-relevant way.

In practice:

• ESRS define what is mandatory for large companies

• GRI provides a solid and internationally recognized foundation

• VSME offer a lighter and more accessible approach for SMEs
