CSRD Reporting in Ireland: The Complete Guide for 2026

The Corporate Sustainability Reporting Directive (CSRD) is now in force across the EU, and Irish companies are facing their first reporting deadlines. This guide explains exactly which Irish organisations must comply, what the deadlines are, and how to prepare your ESRS-aligned data.

Which Irish Companies Must Report Under CSRD?

CSRD applies in stages. For Irish companies, the thresholds are:

• Large companies — 250+ employees, or €50m+ turnover, or €25m+ balance sheet. First report: FY2025 (due 2026).
• Listed SMEs — Listed on an EU regulated market. First report: FY2028 (due 2029, with optional deferral to 2030).
• Non-EU companies — €150m+ EU turnover with an Irish subsidiary or branch. First report: FY2028 (due 2029).

Most Irish SMEs fall below these thresholds. However, if you supply to a large company (pharma, food, construction, tech), you may be asked for ESG data under Scope 3 requirements.

What Are the ESRS Reporting Standards?

The European Sustainability Reporting Standards (ESRS) define what companies must disclose. There are 12 topical standards organised across three pillars:

• Environment (E1–E5) — Climate change, pollution, water, biodiversity, resource use
• Social (S1–S4) — Own workforce, workers in value chain, affected communities, consumers
• Governance (G1) — Business conduct, ethics, anti-corruption

ESRS requires double materiality — you must report both how sustainability issues affect your business (financial materiality) and how your business affects people and the environment (impact materiality).

CSRD Timeline for Irish Companies

How to Prepare Your CSRD Report

Step 1: Conduct a Double Materiality Assessment

Identify which ESRS topics are material to your business. This determines which standards you must report against. Involve stakeholders — investors, employees, suppliers, communities — to validate your assessment.

Step 2: Map Your ESG Data

Take inventory of where your ESG data currently lives. Most Irish companies find it fragmented across spreadsheets, HR systems, utility bills, procurement records, and supplier questionnaires. Map each data source to the relevant ESRS datapoint.

Step 3: Identify Gaps

For each material ESRS standard, identify which datapoints you have and which are missing. Common gaps include Scope 3 emissions data, supply chain labour practices, and biodiversity impact assessments.

Step 4: Build Evidence Trails

CSRD requires audit-ready evidence behind every reported metric. This means documented data sources, calculation methodologies, and validation processes. Assurance providers (auditors) will verify your disclosures — evidence trails are essential.

Step 5: Use a Structured Platform

Manual reporting with spreadsheets is unsustainable at CSRD scale. A structured ESG data platform like CIS organises your datapoints, maintains evidence trails, and generates ESRS-aligned reports that assurance teams can verify efficiently.

What Happens If You Do not Comply?

CSRD is a directive, which means member states must transpose it into national law. In Ireland, the Corporate Sustainability Reporting Directive will be enforced through existing company law mechanisms. Non-compliance can result in:

• Administrative sanctions and fines
• Public naming of non-compliant companies
• Director liability in serious cases
• Difficulty accessing capital markets (investors increasingly require CSRD-aligned disclosures)

Getting Started

If your Irish company falls under CSRD scope, start now. The first reports are due within months for large companies, and the data collection process takes significantly longer than most teams expect.
