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.

2025 Q4 Greenhouse Gas Indicator Report Cover

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).
