Ireland greenhouse gas emissions moved in the right direction in 2025, with new figures from the Environmental Protection Agency (EPA) showing an overall decline of 2.2%. The latest update is an important signal for climate policy, energy planning, and national decarbonisation efforts, especially as Ireland works toward legally binding emissions targets.
The new EPA release adds to the growing body of official climate reporting available through public bodies such as gov.ie, the Environmental Protection Agency (EPA), and the CSO. It also provides a clearer picture of how sectors linked to Transport, Agriculture, Housing, Climate Action, and Enterprise, Trade and Employment are responding to changing energy use, regulation, and economic conditions.
Ireland greenhouse gas emissions fall in 2025
According to the EPA, Ireland’s greenhouse gas emissions fell by 2.2% in 2025 compared with the previous year. While the drop is modest, it represents continued momentum in the country’s transition to a lower-carbon economy.
The data is closely watched across Government and State agencies, including the Department of the Taoiseach, Climate Action, Transport, Agriculture, Health, and Public Expenditure, because emissions trends influence everything from infrastructure spending to energy security and compliance with EU climate obligations.
Why the latest EPA figures matter
- They show whether Ireland is moving closer to its climate commitments.
- They help assess which sectors are cutting emissions and which are lagging.
- They inform national policy across Finance, Local Government and Heritage, and Enterprise Ireland-linked development planning.
- They shape future decisions on clean transport, farming supports, home energy upgrades, and industrial transition.
Although a 2.2% decrease is welcome, analysts will still focus on whether the reduction is large enough to keep Ireland on track for long-term carbon budgets.
Key sectors behind the emissions trend
Ireland greenhouse gas emissions are heavily influenced by a small number of sectors. In practice, changes in electricity generation, road use, agriculture, and building energy demand often have the biggest impact on the national total.
Public bodies such as the National Transport Authority (NTA), Road Safety Authority (RSA), An Bord Pleanála, Tailte Éireann, the Office of Public Works (OPW), and the Commission for Regulation of Utilities (CRU) all sit within a wider policy ecosystem that can affect future emissions outcomes.
Areas likely to shape future reductions
- Energy: Cleaner electricity and lower fossil fuel use can drive meaningful cuts.
- Transport: Public transport expansion and EV uptake remain central to lowering road emissions.
- Agriculture: Farming remains one of the most important and challenging sectors in Ireland’s climate strategy.
- Buildings: Retrofitting, heat pumps, and energy efficiency upgrades are essential for lasting progress.
These areas are also linked to broader work across Local Government, Housing Agency planning, and national investment frameworks.

What this means for climate policy in Ireland
The latest figures will feed into debate across gov.ie and among agencies including the Revenue Commissioners, Health Service Executive (HSE), IDA Ireland, Enterprise Ireland, and the Central Bank, as climate transition increasingly affects public spending, business costs, health resilience, and investment planning.
For households and businesses, the emissions decline is more than a headline statistic. It reflects real changes in fuel use, mobility, energy efficiency, and industrial performance. For policymakers, it is a reminder that progress is possible, but faster reductions are still needed if Ireland is to meet future sectoral ceilings.
The EPA’s role remains crucial in providing trusted environmental data, just as HIQA, the Data Protection Commission (DPC), the Competition and Consumer Protection Commission (CCPC), and other independent bodies support evidence-based oversight in their own areas.

Outlook after the 2025 EPA update
Ireland greenhouse gas emissions are now on a downward path, but the pace of change will remain under scrutiny. Future reports will determine whether this 2.2% decline marks a durable trend or a temporary improvement driven by short-term factors.
The clear takeaway is that Ireland greenhouse gas emissions are falling, but deeper cuts will be needed across energy, transport, agriculture, and buildings to meet national and EU climate goals. The EPA update is encouraging, yet it also underscores the scale of action still required.
