Ireland’s Decarbonising Zones are turning national climate goals into practical projects on the ground. Across cities, towns and rural areas, local authorities are using selected areas to test solutions for cleaner transport, warmer buildings, renewable energy, biodiversity and climate resilience.
The initiative is designed to show what effective local decarbonisation looks like—and identify projects that could later be expanded across the country.
What are Ireland’s Decarbonising Zones?
A Decarbonising Zone is a defined geographic area selected by a local authority through its Local Authority Climate Action Plan. Each zone combines climate mitigation, adaptation and biodiversity measures suited to local needs.
Rather than following a single national blueprint, councils can develop projects around the challenges and opportunities in their own communities. These zones act as demonstration areas where local authorities can innovate, evaluate results and share successful approaches.
- 41 zones have been identified across Ireland
- 29 are urban, six are part-urban and six are rural
- The combined zone population is approximately 530,522 people
- The combined estimated emissions baseline is 3.9 million tonnes of CO2 equivalent
Local solutions for different challenges
Projects may address mobility, heating, buildings, infrastructure and energy poverty. They can also support skills, employment, wellbeing, circular economy initiatives and sustainable land use. This flexible model recognises that a rural zone may need different measures from a densely populated urban area.
For residents, the impact could include improved walking and cycling facilities, more energy-efficient homes, cleaner transport options, better biodiversity protection and stronger community participation in climate planning.
Funding and national support
The Department of Climate, Energy and the Environment established an interdepartmental and interagency advisory group to support local authorities. The group helps councils address shared challenges and develop projects with potential for wider replication.
A national Decarbonising Zone Demonstrator Fund of €1.8 million was established in 2026. The ring-fenced funding is intended to help councils advance projects within their zones and demonstrate which interventions deliver the greatest local impact.
A separate European Regional Development Fund scheme worth €2.5 million was also launched for the Northern and Western Region. The department is contributing €1 million, with the scheme focused on innovative, community-led climate projects.
Mapping Ireland’s climate demonstration areas
Ireland is participating in the ESPON Ireland Targeted Analysis of Decarbonisation Zones project. The study is examining and mapping the 41 zones to improve understanding of their characteristics and inform future policy. An interactive map has also been developed as part of the work.
The 2025 Decarbonising Zone Advisory Group Annual Report records progress, opportunities and challenges identified during the year. Case studies from Carlow, Dún Laoghaire-Rathdown, Kildare, Leitrim, Offaly, Tipperary and Waterford provide examples of how local authorities are approaching the programme.
Why the zones matter for Ireland
The programme connects national climate policy with decisions made locally. It also creates a structured way to test ideas before wider investment, while giving communities a role in shaping projects that affect transport, homes, public spaces and natural areas.
Agencies including the Environmental Protection Agency, local authorities and public bodies may contribute relevant expertise, while findings can support future work across energy, housing, transport and biodiversity policy.
Key takeaway
Ireland’s Decarbonising Zones are more than mapped areas: they are practical test beds for local climate action. Their success will depend on clear delivery, community involvement, reliable evaluation and the ability to scale effective projects nationwide.
