GRI for SMEs
GRI Standards are designed for organisations of all sizes — not just large multinationals. SMEs can report under GRI using a proportionate approach, focusing on the most material topics rather than attempting full coverage. Here is how SMEs can use GRI effectively without the complexity that large companies face.
GRI Standards are designed for organisations of all sizes — not just large multinationals. GRI Standards apply to any organisation that wants to use them — there is no minimum size requirement.
How GRI applies to SMEs — the proportionality principle
GRI Standards apply to any organisation that wants to use them — there is no minimum size requirement. However, GRI recognises that smaller organisations face different resource constraints and sustainability impact profiles than large multinationals.
The GRI materiality process (GRI 3) is the SME's friend — it means you only need to report on topics where you have significant impacts. An SME manufacturing company with 100 employees might find that worker health and safety (GRI 403), environmental compliance (GRI 307 — now integrated into GRI 2), and supplier social assessment (GRI 414) are its most material topics — and can produce a credible GRI report covering just these areas.
GRI 2 (General Disclosures) is mandatory for all GRI reporters — including SMEs. This requires general organisational information, governance disclosure, stakeholder engagement description, and reporting practice. For an SME, GRI 2 takes a few days to complete — the general information is already known, governance is simpler, and stakeholder engagement is often more direct and informal.
Topic Standards: An SME need only use Topic Standards for its material topics — not all 40+ standards. A manufacturing SME might use GRI 305 (emissions), GRI 403 (health and safety), and GRI 401 (employment) — three standards covering its most significant impacts. This is a proportionate and credible GRI report.
GRI and VSME — how the two frameworks align for SMEs
The VSME (Voluntary SME Standard) being developed by EFRAG covers similar ground to a light-touch GRI report for SMEs — with the additional advantage of being specifically designed to satisfy large CSRD company supply chain data requests.
Overlap between VSME Module B and GRI: VSME Module B GHG emissions data (Scope 1 and 2) satisfies GRI 305-1 and 305-2. VSME Module B energy data satisfies GRI 302-1. VSME Module B headcount and H&S data satisfies GRI 401-1 and GRI 403-9. VSME Module B governance statements satisfy GRI 205-1 (anti-corruption policy) and parts of GRI 2.
For SMEs wanting to do both: start with VSME Module B to satisfy customer data requests, then expand to full GRI reporting for topics where you want more comprehensive stakeholder disclosure. The VSME data collection is a subset of what a full GRI report requires — building VSME data infrastructure first reduces the incremental effort to add full GRI reporting.
For SMEs choosing between the two: if your primary motivation is satisfying large customer ESG questionnaires — VSME is simpler, more targeted, and more explicitly designed for that purpose. If your motivation is broader stakeholder communication, investor relations, or preparing for potential future CSRD scope — GRI provides a more comprehensive framework with global recognition.
Practical GRI reporting for SMEs — the starter approach
A proportionate first GRI report for an SME can be produced in 4–8 weeks using primarily data already available within the business.
Step 1 — GRI 2 (General Disclosures): Complete the organisational profile, activities and workers, governance, strategy and policies, stakeholder engagement, and reporting practices sections. For an SME, this takes 2–3 days — the information is mostly known and documented in existing company materials.
Step 2 — GRI 3 (Material Topics): Conduct a lightweight materiality assessment — list 10–15 sustainability topics relevant to your sector, assess which have the most significant impacts (internal assessment supplemented by stakeholder conversation), identify the top 3–6 material topics. For an SME, this takes 3–5 days.
Step 3 — Topic Standards for material topics: For each material topic, collect the data required by the relevant GRI Topic Standard and complete the 3-3 management approach disclosure. For 4 material topics, this typically takes 1–2 weeks.
Step 4 — GRI Content Index: Compile the mandatory Content Index listing all disclosures, their location in the report, and any omissions with reasons. This takes 1–2 days once the report content is complete.
Step 5 — Review and publish: Internal review, proofread, and publish on your website. Submit a GRI report notification via the GRI website to be listed in the GRI Sustainability Disclosure Database — increasing visibility with investors and rating agencies.
Total estimated effort: 4–6 weeks part-time for one person with no prior GRI experience. Subsequent years: 1–2 weeks updating prior year data and narrative.
Frequently asked questions
Do SMEs need to pay to use GRI Standards?
No — GRI Standards are freely available at globalreporting.org. There is no licensing fee or membership requirement to use GRI Standards for sustainability reporting. GRI funding comes from large company membership and foundation support — SME reporting is effectively subsidised by the larger reporting community.
Can an SME claim GRI alignment without third-party assurance?
Yes — GRI alignment ('with reference to GRI Standards' or 'in accordance with GRI Standards') does not require third-party assurance. SMEs can self-declare GRI alignment by publishing a compliant GRI Content Index. Assurance is recommended but optional — and for SMEs, third-party review is significantly less expensive than full assurance (typically €3,000–€10,000).
How does GRI reporting help an SME win contracts from large CSRD-reporting customers?
Large CSRD companies need ESG data from their tier 1 suppliers for Scope 3 Category 1 calculation and ESRS S2 supply chain disclosure. A GRI-reporting SME supplier provides standardised, publicly accessible ESG data that reduces the large company's data collection burden. GRI 305 emissions data, GRI 403 H&S data, and GRI 205 anti-corruption disclosure directly answer the most common supply chain ESG questionnaire questions.
