Green Public Procurement in Ireland: Legal Requirements and Best Practice

Ireland's Green Public Procurement National Action Plan commits public bodies to embedding environmental criteria in procurement. For works contracts, the Government's BIM Mandate and the CWMF's climate action requirements now make environmental specification mandatory in certain project types. Above-threshold procurements must also consider life-cycle costs — including energy, operational and maintenance costs — when setting award criteria under Regulation 67 of S.I. 284/2016.

The EU's mandate goes further: the Clean Vehicles Directive requires public bodies to procure a minimum percentage of clean vehicles in fleet renewals. The EU Taxonomy Regulation increasingly affects capital projects where public funding is involved.

Environmental requirements can be embedded in technical specifications, selection criteria, award criteria or contract performance conditions. The most robust approach uses technical specifications to define minimum environmental standards — for example, requiring products to carry EU Ecolabel or equivalent certification, or specifying minimum energy efficiency ratings for equipment.

For construction contracts, technical specifications should address embodied carbon (particularly for materials-intensive structures), operational energy performance, waste management and biodiversity. CWMF guidance supports inclusion of these criteria and the Government's climate action targets make them increasingly expected.

Life-cycle costing (LCC) is an increasingly used award criterion for procurements where running costs are significant — building projects, fleet purchases, ICT systems. LCC calculations consider acquisition cost, operating cost, maintenance cost, end-of-life cost and any environmental externality costs. The EU methodology for LCC is set out in Commission Delegated Regulation (EU) 2019/1748.

Weighting environmental award criteria appropriately is a judgment call: criteria must be linked to the subject matter of the contract and must not be set at a level that effectively excludes compliant tenderers. A common practice is to weight the environmental award criterion at 10–20% alongside technical quality and price.

Leading contracting authorities in Ireland have moved beyond minimum GPP compliance to use procurement as a driver of climate ambition. This includes requiring Environmental Management System certification (ISO 14001 or EMAS) as a selection criterion for large contracts; specifying minimum recycled content for construction materials; requiring contractors to produce and implement Carbon Management Plans.

Building GPP into procurement at specification stage — rather than treating it as an add-on at evaluation — delivers better outcomes and stronger audit defensibility. GovIQ supports this by flagging mandatory GPP requirements at the routing stage based on contract type, value and sector.
