The CO₂ Performance Ladder is driving sustainable procurement in Ireland and helps Irish businesses and the government turn climate ambitions into real action.
The CO₂ Performance Ladder is driving sustainable procurement in Ireland and helps Irish businesses and the government turn climate ambitions into real action.

Ireland’s two-year pilot of the CO₂ Performance Ladder (2023–2025), led by the Irish Green Building Council (IGBC) in partnership with SKAO, has been successfully completed. The pilot demonstrated that the Ladder is both feasible and effective within the Irish context – and that it drives meaningful carbon reduction across the built environment.
Transport Infrastructure Ireland (TII) was the first procuring authority to apply the Ladder as an award criterion. The results on the first completed project were striking: an 84.5% reduction in Scope 1 and 2 emissions and 311 tonnes of CO₂ equivalents saved. Three companies – Roadstone, Jons Civil Engineering and Colas JV – have now achieved company-wide certification.
Building on this success, TII has embedded the Ladder into three new four-year frameworks, and IGBC is preparing for a broader national rollout supported by Construct Innovate. Several additional public bodies have expressed strong interest in adopting the Ladder.
“By incorporating the CO2 Performance Ladder into their tendering processes, public bodies can send a clear message to the market: sustainability is not an option; it is an imperative. The CO2 Performance Ladder is a proven instrument in public procurement and carbon emissions reduction.”
– Pat Barry, CEO at the Irish Green Building Council
The CO2 Performance Ladder in Ireland is coordinated by the Irish Green Building Council (IGBC) in collaboration with the Foundation for Climate Friendly Procurement and Business (in Dutch: SKAO).

Colas Joint Venture is the first company in Ireland to achieve a company-wide Level 3 certification on the CO₂ Performance Ladder. In this video, Colas explains why they chose the Ladder, how it supports their sustainability strategy, and the changes they have made in their operations — from switching to renewable fuels to introducing Ireland’s first fully electric Impact Protection Vehicle. Their achievement marks an important milestone in the use of the Ladder as a Green Public Procurement tool in Ireland.
Micheál O’Connor, Senior Procurement Executive at Transport Infrastructure Ireland (TII) talks about his experience implementing the Ladder into their procurement process.
