Your Biggest Customer Is Now Your Sustainability Regulator: CSRD for Irish SMEs

07 Sept 20257 min read

Why this matters now

The Corporate Sustainability Reporting Directive (CSRD) is reshaping supply chains across Europe. While only large companies and listed SMEs will be required to publish reports in the next few years, those reports must cover their entire value chain. That means suppliers of every size are already being asked for emissions, resource use, and policy data.

The commercial risk for SMEs is not a regulator’s fine but lost contracts. Ibec’s 2025 case study on Idiro Analytics describes how the Irish consultancy was required by a telecoms
client to complete a formal disclosure through the Carbon Disclosure Project platform, a process they found complex and resource-intensive . Similar requests are now landing in the inboxes of manufacturers, food producers, and professional services firms.

The reporting waves

The EU’s “stop-the-clock” decision extended deadlines for many companies. Ireland transposed these changes into law in July 2025 (S.I. 309/2025). The current reporting timetable is:

  • Large public interest entities (PIEs) with more than 500 staff: reporting on FY2024, publishing in 2025 (unchanged).
  • Other large companies: reporting on FY2027, publishing in 2028 (delayed).
  • Listed SMEs: reporting on FY2028, publishing in 2029 (delayed, with an opt-out option).

In practice, procurement teams at Wave-1 customers are already gathering supplier information to prepare their own 2025 filings. For SMEs, the regulatory clock may read 2028, but the procurement clock is already ticking.

Why spreadsheets no longer work

Many SMEs still manage ESG data in spreadsheets. According to PwC’s 2024 Global CSRD Survey, 74% of companies rely on spreadsheets for sustainability data management. This approach is no longer fit for purpose when buyers require:

Consistent data structures across multiple tenders and portals

  • Audit trails showing who entered which number and when
  • Linked evidence such as bills, waste transfer notes, and travel records
  • Outputs that can be uploaded into structured, machine-readable systems

Spreadsheets cannot meet these demands. SMEs that continue to rely on them risk errors, rework, and reduced credibility with buyers.

The Supplier ESG Datapack

The practical solution is to create a standardised, auditable information pack that can be shared across multiple customers. We call this the Supplier ESG Datapack. It should contain:

Core data fields

  • Energy: annual electricity and gas use (kWh) by site
  • Fuel: litres of diesel, petrol, or LPG used in operations and logistics
  • Waste: tonnes handled by recycling, recovery, and landfill
  • Travel: distance by mode from expenses or travel systems
  • Policies: signed statements covering safety, anti-corruption, data protection, and human rights

Evidence

Utility bills, contractor reports, travel logs, and signed policy documents.

Assurance trail

Calculation methods, responsible data owners, approvals, and any estimates used.

Unlike ad hoc questionnaires, a Datapack is proactive, standardised, and reusable. It shortens turnaround times, keeps submissions consistent, and creates the audit trail that customers and their auditors require.

Sector playbooks

Manufacturing exporters

  • Expect requests for physical resource flows under ESRS E5, measured in tonnes or cubic metres.
  • Be ready to provide product-level carbon footprints for key exports.
  • Align supplier onboarding with due-diligence requirements on provenance, certification, and labour standards.

Agri-food suppliers

  • For processors, the majority of emissions lie on farm: livestock methane, fertiliser use, and land management.
  • Irish co-ops are piloting digital platforms to collect data from farmers, including biodiversity metrics such as hedgerow length.
  • SMEs supplying into these chains should prepare to provide consistent, defendable farm-level or input data.

Funding support

Irish SMEs can offset the cost of building these capabilities through targeted supports:

  • Enterprise Ireland Digital Discovery Grant: covers 80% of project costs up to €6,300 (grant cap €5,000).
  • Climate Action Voucher: up to €1,800 for advisory support to start sustainability planning.
  • GreenStart: funding for expert advice to introduce management systems and identify savings.
  • GreenPlus: grants up to €50,000 for deeper capability building and staff training.
  • LEO Green for Business: two days of free, one-to-one mentoring for micro-SMEs.
  • LEO Energy Efficiency Grant: 50% funding up to €5,000 for energy monitoring and tracking systems.

Funding is competitive and budget-limited. Early applications create a strategic advantage.

A 90-day starter plan

By day 30

By day 60

By day 90

  • Appoint a data lead.
  • Map data sources (utilities, HR, travel, waste).
  • Ask top customers for their supplier templates and timelines.
  • Collect utility and waste data into a central evidence folder.
  • Draft calculation notes and a simple change log.
  • Build the first version of the Supplier ESG Datapack.
  • Run a test submission with a key customer or tender portal.
  • Capture gaps and prioritise automation (e.g. monthly utility feeds).

The payoff

  • Market access: meet procurement requirements and stay eligible for contracts.
  • Efficiency: faster responses and reduced rework.
  • Credibility: stronger standing with banks, investors, and regulators.
  • Future readiness: systems in place well before direct reporting obligations.

Conclusion

For Irish SMEs, CSRD is already reshaping the market. Procurement teams need reliable supplier data now, years before most SMEs face direct obligations. Those who act early will protect contracts, lower reporting costs, and build trust with financiers and partners.
