Ireland greenhouse gas emissions moved in the right direction in 2025, with new figures from the Environmental Protection Agency (EPA) showing a national decline of 2.2%. The latest update is an important signal for climate policy, energy transition planning, and public accountability across gov.ie departments and state agencies.
The data matters well beyond the environmental sector. It informs decisions touching Climate Action, Transport, Agriculture, Housing, Health, Public Expenditure, and Finance, while also shaping how the Department of the Taoiseach and wider public bodies respond to Ireland’s legally binding emissions targets.
Ireland greenhouse gas emissions fall in 2025
According to the EPA, Ireland recorded a 2.2% drop in greenhouse gas emissions in 2025. While any reduction is significant, the broader context remains crucial: Ireland still faces major pressure to accelerate decarbonisation if it is to remain on track for climate commitments over the coming years.
The figures are likely to be closely watched across gov.ie, the CSO, the Commission for Regulation of Utilities (CRU), the National Transport Authority (NTA), and departments responsible for Climate Action, Agriculture, Transport, Housing, and Enterprise, Trade and Employment. Emissions data also helps guide policy choices involving energy security, industrial competitiveness, farming practices, and household costs.
Why the 2.2% decline matters
- It shows that emissions can move downward even during a period of economic and population growth.
- It provides a measurable benchmark for future climate reporting and sector-by-sector action.
- It increases pressure on high-emitting sectors to deliver deeper cuts.
- It supports evidence-based policymaking across Revenue Commissioners, Local Government and Heritage, and national agencies involved in infrastructure and planning.

What could be driving Ireland greenhouse gas emissions down?
Although detailed sectoral explanations are typically unpacked in technical reporting, a reduction in Ireland greenhouse gas emissions is often linked to a combination of factors such as cleaner electricity generation, changes in fuel use, efficiency measures, and shifting patterns in transport or agriculture. The EPA’s reporting plays a central role in showing where progress is real and where structural weaknesses remain.
State bodies such as the EPA, Met Éireann, An Bord Pleanála, Office of Public Works (OPW), and Tailte Éireann all contribute, directly or indirectly, to the wider planning environment in which climate policy operates. Likewise, agencies including Enterprise Ireland, IDA Ireland, Bord Bia, Teagasc, and the Marine Institute influence how businesses and land-use sectors adapt to a lower-carbon economy.
Sectors that remain under scrutiny
- Agriculture: A major part of Ireland’s emissions profile and central to future reductions.
- Transport: A key area for the National Transport Authority (NTA), Road Safety Authority (RSA), and wider public investment planning.
- Energy: Cleaner generation and grid reform remain critical.
- Buildings and housing: Retrofitting and planning policy will affect long-term emissions outcomes.

What happens next for climate policy in Ireland?
The latest Ireland greenhouse gas emissions update is likely to feed into future decisions by the Department of the Taoiseach, Climate Action officials, Finance planners, Local Government and Heritage teams, and agencies such as the Environmental Protection Agency (EPA). It also has implications for the public, from home energy upgrades to transport choices and business compliance expectations.
For readers tracking Irish government policy, the key takeaway is simple: a 2.2% drop is progress, but not a finish line. Ireland greenhouse gas emissions must continue falling at a stronger pace if the country is to meet long-term climate goals and build a more resilient economy.
