My Department is leading an ambitious sustainability agenda and has progressed a wide array of measures to improve the overall sustainability of our school buildings as part of our work towards 2030 and 2050 climate targets. This performance has been recognised at both national and international level with sustainable energy awards for excellence in design, specification and delivery. My Department's policy is supported by a strong research programme with fifty-six research programmes at various stages.
The first School Sector Climate Action Mandate was published in 2023 and is reviewed and published annually in line with the requirements of the Government’s Climate Action Plan. The School Sector Climate Action Mandate www.gov.ie/en/publication/a1673-school-sector-climate-action-mandate/ has been updated for 2025. The content of the School Sector Climate Action Mandate strongly reflects the requirements of the Public Sector Climate Action Mandate.
The School Sector Technical Climate Action Roadmap 2025 to 2030 www.gov.ie/en/de has also been updated for 2025 and published. The roadmap provides an overview of the school sector requirements and roadmap to 2030 and towards 2050. It includes the strategic vision and outlines the high-level initial trajectory for the school sector delivery of its energy efficiency and greenhouse gas emission reduction targets.
My Department, in collaboration with the Department of Climate Energy and the Environment, has developed a jointly funded School Sector Decarbonisation Pathfinder Programme. The programme is administered by the Planning and Building Unit in my Department and the Sustainable Energy Authority of Ireland (SEAI), with devolved delivery support from Education and Training Boards (ETBs). This pathfinder programme currently has 153 projects completed or active decarbonisation projects across Ireland. The Pathfinder 2025 Programme involves heating decarbonisation projects across approximately 65 schools. Under this programme schools will transition towards renewable heat sources, including air-source heat pumps and biomass heating systems. This decarbonisation glide path delivery approach commences the move from high carbon fossil fuel heating provision in existing schools by phasing out as part of the transition to zero carbon all existing high carbon fossil fuel
(oil) boilers in schools towards renewable heating, supported where necessary by a high efficiency LPG gas boiler. This programme will be further expanded in 2026 and 2027.
My Department also secured funding through REPowerEU in 2024 to support an expanded school pathfinder decarbonisation and retrofit programme in 2025. Under this initiative, 28 schools progressed to full retrofit works in summer 2025, with all schools transitioning to renewable heating systems as part of the project. Additional funding has since been secured to fund an additional 12 schools under this programme in summer 2026.
Earlier this year, my Department also launched the Climate Action Summer Works Scheme (CASWS). This multi-annual programme will support schools in implementing sustainable energy measures including cavity wall and attic and roof insulation, windows and doors, LED lighting, and electric vehicle (EV) charging infrastructure. 1,430 applications were received, of which 198 were approved in the first tranche for commencement in summer 2026.
My Department are delivering an extensive roll out of photovoltaic panels to schools. This sees the provision of 6 kW of Photovoltaic Panels in all schools, funded under the Climate Action Fund. This is providing renewable electricity to these schools for use on site during school opening times and also income for the electricity they export to the grid via the clean export guarantee tariff. This tariff provides an opportunity for micro-and small-scale generators in Ireland to receive payment from their electricity supplier for all excess renewable electricity they export to the grid. To date, over 3,300 schools have been approved for funding with over 2,402 schools so far confirming their installation as complete.
Another key initiative of my department is to establish a national energy profile of all schools. Phase 1 of the energy inventory profile (which comprised all schools across five counties) was completed in 2022 and my Department was successful with an application to REPowerEU in 2024 for funding that will see all remaining schools completed. This work is well underway and involves energy assessors gathering focused information on energy use, building types, age, and size along with an overview of general fabric and energy aspects of electrical and mechanical systems in approximately 3,300 schools.
As part of the energy inventory survey, the Department has developed with support from the SEAI a dedicated energy and carbon rating system for schools called SEACER (School Energy and Carbon Estimated Rating) based on Non-Domestic Energy Assessment Procedures and statistical techniques. The SEACER is a relational database, which performs numerous calculations to determine a SEACER rating. The rating system relational database allows all the data for a large number of schools to be consolidated into a portfolio-wide database.
The results of this survey and the SEACER ratings for schools will enable the Department to identify and prioritise areas for future capital investment in schools, supporting the transition to renewable energy sources and continue to help schools improve the energy rating of their school buildings.
