Can Small Suppliers Survive Green Procurement Rules?

Ireland’s green procurement ambitions are among the most progressive in Europe. But as sustainability obligations stack up, from Circular 17/2025 to the EU’s CSRD, small suppliers face a pressing question: are these rules designed to include them, or to leave them behind?

A New Era of Green Procurement in Ireland

Ireland’s public procurement landscape changed decisively in July 2025 when the Department of Public Expenditure issued Circular 17/2025, making Green Public Procurement (GPP) a binding requirement for all public bodies. Replacing voluntary guidance, the circular aligns with the Buying Greener Strategy 2024-2027 and introduces a ‘comply or explain’ obligation: any failure to apply national GPP criteria on above-threshold contracts must now be formally justified and reported annually to the EPA. Life-cycle costing, looking beyond the lowest upfront price, is now the expected standard.

Sitting above the domestic framework is the EU’s Corporate Sustainability Reporting Directive (CSRD), transposed into Irish law in July 2024. Large public-interest entities began reporting on their 2024 data under the European Sustainability Reporting Standards (ESRS) from 2025. Because those standards require disclosure on the entire value chain, including Scope 3 emissions from suppliers, the compliance burden flows directly downstream to smaller businesses. Irish SMEs are formally outside the CSRD’s scope for now, but that distinction offers little protection in practice: if a large customer demands sustainability data as a condition of contract, the legal threshold is irrelevant.

The EU’s Omnibus I package (February 2025) has since proposed significant simplification, raising reporting thresholds so only companies with over 1,000 employees and €450m+ turnover face mandatory CSRD obligations, down from roughly 50,000 in-scope companies to around 11,700. Ireland enacted the associated ‘Stop the Clock’ Directive in July 2025, delaying Wave 2 and Wave 3 obligations by two years. The Voluntary SME Standard (VSME), formally recommended by the European Commission in July 2025, gives small businesses a standardised, proportionate format for sustainability disclosures. But it remains voluntary, and adoption by buyers has been uneven.

The Gap Between Policy and Reality

According to procurement data, 95% of Irish public procurement contracts are awarded to firms with fewer than 250 employees. The green rules being introduced will therefore land, in large measure, on small businesses. And the readiness gap is wide, a report published in early 2025 found that SMEs in European supply chains were being asked anywhere from 20 to 250 sustainability questions per customer, with no standardisation and no support infrastructure. The four biggest barriers identified: cost, limited human resources, knowledge gaps, and inadequate data systems.

Industry bodies have flagged this trickle-down effect explicitly: large Irish companies’ value chains are deeply interwoven with SME suppliers across food and beverage, construction, financial services and professional services. The sustainability disclosure requirements flowing from the CSRD reach these small businesses well before any formal regulatory deadline. A small producer supplying a large retailer, or a regional contractor working for a major infrastructure company, faces the same data demands as a formally in-scope entity, but without the timelines, guidance or resources that formal compliance typically brings.

Ireland’s unique economic structure sharpens the risk, and the co-existence of a large multinational sector, many of whom are already Wave 1 CSRD reporters and a vibrant domestic SME base means that sustainability compliance infrastructure is distributed very unevenly. Multinationals have global ESG teams and established reporting frameworks. A small business in Sligo or Kilkenny does not. So if green procurement requirements become a de facto market entry barrier, the beneficiaries will be large incumbents, not the locally rooted businesses that sustain regional economies.

What Needs to Change

The Climate Action and Low Carbon Development (Amendment) Act 2021 commits Ireland to a 51% emissions reduction by 2030, one of the most demanding targets in the EU. Procurement is a powerful lever, and Circular 17/2025 and the Buying Greener Strategy are genuine progress. But if it isn’t accessible, ambition stays aspiration rather than becoming real policy.

Four changes, in particular, would make a material difference:

The VSME standard needs active promotion and enforcement across Irish public and private procurement: The European Commission has recommended that large companies limit data requests from SME suppliers to the VSME framework, the OGP, Enterprise Ireland and the 31 Local Enterprise Offices should communicate this right clearly and consistently, so small businesses know they can refuse excessive information demands.
The SME Test embedded in Circular 17/2025 needs binding force: A micro-enterprise supplying a county council should not face the same green documentation burden as a large infrastructure contractor. Graduated, proportionate requirements, scaled to contract size and sector, are essential if the policy is to be inclusive rather than exclusionary.
Ireland needs a coordinated national SME sustainability support programme: The EPA already provides GPP training for suppliers. The LEOs have deep community reach. Enterprise Ireland supports business development. These assets are complementary but fragmented. A single, well-resourced programme offering free carbon toolkits, reporting templates and advisory support, built on existing infrastructure, would dramatically lower the cost of compliance for small businesses.
Prompt payment is a green economy issue: Sustainability investment requires capital, and capital requires cash flow. A business waiting 60 or 90 days for payment cannot simultaneously invest in emissions measurement or green upgrades. Rigorous enforcement of the EU Late Payment Directive obligations in public procurement is, in this context, as much a climate policy as a commercial one.

Ireland has real cause for pride in its green procurement ambitions and the Circular 17/2025 is a serious policy. The Buying Greener Strategy is well conceived and the CSRD, even in its simplified form, will raise standards across European supply chains in ways that matter. If green procurement rules, in practice, exclude the businesses that win the vast majority of those contracts, the policy risks undermining its emissions impact. It may simply redistribute opportunities to larger firms better equipped to navigate the administrative burden.
