What Is CSRD? The EU Corporate Sustainability Reporting Directive Explained
CSRD (Corporate Sustainability Reporting Directive) is the EU regulation that requires roughly 50,000 companies to publish detailed sustainability information using the European Sustainability Reporting Standards (ESRS). It replaced the older NFRD in January 2024 and phases in by company size: large public-interest entities reporting from 2025 (FY 2024), other large companies from 2026 (FY 2025), and listed SMEs from 2027 (FY 2026, with opt-out until 2029). Per the European Commission's official CSRD page, the directive's goal is to make sustainability data as reliable and comparable as financial data — so investors, lenders, and supply-chain partners can integrate ESG factors into decisions.

CSRD vs ESRS vs vSME: How the Three Fit Together
CSRD is the law. ESRS are the 12 standards (E1–E5 environmental, S1–S4 social, G1 governance, plus 2 cross-cutting) that companies must report against under CSRD. VSME is the voluntary standard for unlisted small and medium enterprises that fall outside CSRD scope but need ESG data to satisfy bank loan applications, customer questionnaires, or supply-chain due diligence under CSDDD. A typical EU SME today is not legally required to report under CSRD — but is increasingly asked by larger CSRD-reporting customers to disclose Scope 1+2 emissions via the VSME template. The three tools on this hub solve those three layers in order.
Who Must Report Under CSRD in 2026
Mandatory CSRD scope in 2026 (FY 2025): EU companies meeting two of three thresholds — over 250 employees, over €50M turnover, over €25M balance sheet. Listed SMEs follow from FY 2026. Non-EU parents with €150M+ EU turnover from FY 2028. If you are below these thresholds but a CSRD-reporting customer asks for your data, use the VSME Report Generator — it is the EFRAG-endorsed format for voluntary SME reporting and is shorter and cheaper than full ESRS.
Why Free CSRD Tools Matter for SMEs
Commercial CSRD/ESRS compliance software costs €5,000–€50,000/year. For SMEs under voluntary VSME scope, that is disproportionate to the disclosure burden. The tools on this hub are free, browser-based, and never send your emissions data to a server — useful for SMEs running first-year reporting or piloting CSRD readiness internally before procuring enterprise software. They are not a replacement for assurance-grade software when limited assurance becomes mandatory under CSRD, but they let you produce a credible first draft for internal review and supply-chain questionnaires.
CSRD Omnibus Simplification: 2-Year Delay and Reduced Datapoints (2025-2026)
In February 2025 the European Commission adopted the Omnibus I Simplification package, followed by the "Stop-the-Clock" directive published in April 2025 in the Official Journal — which most companies now use as their planning baseline. Two big changes for CSRD scope: (1) Wave 2 (other large companies, FY 2025 originally due 2026) and Wave 3 (listed SMEs, FY 2026 originally due 2027) are pushed back 2 years — new first reports FY 2027 and FY 2028 respectively. (2) The Commission is also proposing to raise the scope threshold to 1,000 employees, which would remove roughly 80% of currently in-scope companies (subject to Parliament/Council approval throughout 2025-2026). ESRS datapoint count is targeted for ~50-70% reduction through EFRAG's ongoing revision, with the shortened standards expected to publish in 2026. Practical impact: if you were scoping first-year CSRD compliance for FY 2025, you now have until FY 2027 — but ESG customer questionnaires under CSDDD have NOT been delayed, so voluntary VSME reporting remains the pragmatic near-term path.

Frequently Asked Questions
What does CSRD stand for?
CSRD stands for Corporate Sustainability Reporting Directive — the EU regulation (Directive 2022/2464) that requires large EU companies and listed SMEs to publish detailed sustainability disclosures using ESRS. It replaced the older NFRD in January 2024 and applies on a phased timeline through 2029.
Who has to comply with CSRD?
CSRD applies to: large EU public-interest entities (FY 2024 first report due 2025), other large EU companies meeting 2 of 3 size thresholds — 250+ employees, €50M+ turnover, €25M+ balance sheet (FY 2025 first report due 2026), listed EU SMEs (FY 2026 first report due 2027, with an opt-out until 2029), and non-EU parents with €150M+ EU turnover (FY 2028).
What is the difference between CSRD and ESRS?
CSRD is the EU law mandating sustainability reporting. ESRS (European Sustainability Reporting Standards) are the 12 detailed standards (E1–E5 environmental topics, S1–S4 social, G1 governance, plus 2 cross-cutting) that companies must report against under CSRD. CSRD is the "what" (you must report); ESRS is the "how" (here are the datapoints).
What is double materiality under CSRD?
Double materiality means a company must report on (1) how sustainability matters affect the company (financial materiality — climate risk, regulatory cost) AND (2) how the company affects people and the environment (impact materiality — emissions, labor practices). It is the cornerstone of CSRD/ESRS and differs from US SEC rules which focus only on financial materiality.
When does CSRD start for SMEs?
CSRD applies mandatorily to LISTED SMEs starting FY 2026 (first report due 2027), with a delay option to FY 2028. Unlisted SMEs are not in mandatory scope but can use the VSME (Voluntary SME) standard — a simplified EFRAG-endorsed format — to respond to bank, customer, and investor questionnaires without doing full CSRD-grade reporting.
Do I need expensive software for CSRD/VSME?
For full CSRD with limited assurance: yes, eventually — assurance-grade audit trails require enterprise software. For first-year readiness, internal exploration, or VSME voluntary reporting: free browser tools (like the ones on this hub) are sufficient to produce a credible draft. Many SMEs start free, then migrate to paid platforms only when an assurance provider requires it.
What is the CSRD Omnibus Simplification and when does it take effect?
The Omnibus I package (Feb 2025) plus the "Stop-the-Clock" directive (April 2025, Official Journal) delay CSRD Wave 2 by 2 years — Wave 2 (large non-PIE companies) now first report FY 2027 (due 2028), Wave 3 (listed SMEs) FY 2028 (due 2029). The Commission is also proposing to raise the employee threshold to 1,000, which would remove ~80% of currently in-scope companies (still subject to Parliament/Council approval throughout 2025-2026). ESRS datapoint count targeted for 50-70% reduction. Source: European Commission Omnibus I package.
Do I still need to prepare for CSRD if my customer asks for ESG data now?
Yes. The CSRD Omnibus delay pushes back the LEGAL first-report deadline, but customer supply-chain due diligence under CSDDD has not been delayed. Large CSRD-reporting customers (who ARE still on the original timeline) will keep asking their suppliers for Scope 1+2 emissions data, VSME reports, and ESG datapoints regardless of your own reporting obligation. Voluntary VSME reporting remains the pragmatic path for SMEs to answer these questionnaires without full CSRD-grade audit trails.
