The sheet called 'Data' contains measurement results from each sampling location for the period from 2007 to 2025.
NRMN low volume aerosol sampler data 2007 to 2025
Year: 2026
This spreadsheet contains information on 14 low volume aerosol samplers belonging to the National Radiation Monitoring Network (NRMN). Further information about the location of each instrument is available in the sheet called 'Stations'. The sheet called 'Data' contains measurement results from each instrument for the period from 2007 up to 2025.
Rainwater samples measurement results 2007 to 2025
Year: 2026
This spreadsheet contains the results of EPA testing on rainwater samples collected each month from monitoring stations in Dublin. The samples are checked for small amounts of radioactive substances, including: Caesium-137 (Cs-137) Caesium-134 (Cs-134) Iodine-131 (I-131) Beryllium-7 (Be-7), which is a naturally occurring radioactive substance found in the atmosphere. What the spreadsheet contains The "Data" sheet contains results from each monitoring station for the years 2007 to 2025. The "Stations" sheet provides information about the monitoring locations.

This report presents the findings of an online survey carried out by Interactions Research in December 2025 on behalf of EPA to assess the attitudes of the public in Ireland to radiation.
Water Quality in Ireland 2025
An Indicators Report, June 2026
Year: 2026
This report looks at how Ireland’s water quality has changed in 2025, using the latest monitoring data for rivers, lakes, groundwater, estuaries and coastal waters. Overall, the report shows no major change in water quality in 2025. Nutrient levels remain too high in a large proportion of water bodies. Levels fluctuate year on year but are not improving overall over the long term. The biological health of our rivers and lakes has shown little change with slightly more than half (54%) in good or better biological quality.

Climate Ireland Adaptation Network Working Group 4: Resilience indicator development
Year: 2026
The Climate Ireland Adaptation Network is a practitioner network aimed at sharing expertise and creating learning opportunities around adaptation in Ireland as well as improving the consistency of adaptation implementation. The four working groups were established to enable participants to share their views, practices, and perspectives around four key challenges for adaptation in Ireland. A primary goal of the CIAN working groups was to enhance communication between stakeholders, build stronger links across Ireland’s adaptation community, and provide a forum to discuss adaptation topics and identify practitioner needs and knowledge gaps. The final reports represent the consensus from discussions of members of the relevant working groups.

Quarterly Greenhouse Gas Emissions Indicator Report 2025 Quarter 4
Year: 2026
This is the latest EPA report on quarterly greenhouse gas emissions for Ireland to support more frequent monitoring of national and sectoral progress on climate action. This series complements the national greenhouse gas inventory and projections prepared annually by the EPA. Emissions in Quarter 4 2025 were down by 1.3% on the same quarter last year. This was primarily driven by lower Electricity emissions (-240.5 kt CO₂ eq), partially offset by increases in Buildings (60.8 kt CO₂ eq), Other (39.0 kt CO₂ eq) and Industry emissions (20.8 kt CO₂ eq).
