SEA Spatial Information Sources Inventory
EPA Spatial Data Inventory, November 2025
Year: 2025
This inventory of spatial information sources can be used to help in preparing SEA Environmental Reports and the associated environmental assessments with up to date environmental information. Data sources/links include air quality, climate, biodiversity, flora, fauna, geology, soils, hydrology and water quality. This inventory was last updated in November 2025 and may not be exhaustive. (See Disclaimer below for terms of use).
Quarterly Greenhouse Gas Emissions Indicator Report 2025 Quarter 2
Year: 2025
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 2 2025 were down by 3.2% on the same quarter last year. This was mainly driven by decreases in the Buildings sector (-296 kt CO₂ eq) driven by reduced demand for heating, and the Agriculture sector (-117 kt CO₂ eq) driven by decreased fertiliser sales.
Water Quality 2019-2024 Summary Report
Year: 2025
This report provides summary information on the status of our rivers, lakes, estuaries, coastal waters (known collectively as surface waters) and groundwaters. It is based on information collected over a 6-year period from 2019 to 2024 under Ireland’s national water quality monitoring programme from over 4,000 surface water bodies and 514 groundwater bodies. It highlights changes in the condition of these waters, identifies the main problems causing water quality issues and sets out what actions need to be taken to protect this important national resource.

Air Quality in Ireland 2024
Year: 2025
Air quality in Ireland is generally good and was compliant with 2024 air quality standards, meeting all EU legal requirements. It will be more challenging for Ireland to meet new and more stringent air quality limits that will come into force from 2030. We need to do more to protect our clean air in towns and cities across Ireland.

Mid-term Evaluation of the National Hazardous Waste Management Plan 2021-2027, Incorporating the 2024 Annual Report
Year: 2025
Under Key Action 19.3 of the National Hazardous Waste Management Plan 2021 – 2027, the EPA is required to conduct a mid-term review of the NHWMP and update actions for the second half of the plan.

Eionet Ireland Network Brochure August 2025
Year: 2025
National Focal Points (NFPs) are the primary national contact points in the Eionet and the EEA works closely with them. Typically based in a national environment agency or environment ministry an NFP is appointed by their EEA member country. The Environmental Protection Agency acts as the NFP for Ireland, coordinating environmental information exchange with the EEA and others. In its NFP role, the EPA maintains and develops the national network. It also facilitates and coordinates contacts, requests and deliveries between national and EU level. The summary booklet was updated in August 2025.

Evidence-based targeting of agricultural measures to reduce nitrogen in catchments to achieve water quality objectives
Year: 2025
This report outlines three updates to the evidence base to support targeting the right measures in the right place to improve water quality. The first update is the assessment of the catchments that need nitrogen load reductions to support good estuarine ecological conditions which incorporates more recent monitoring data since first reported by the EPA in 2021, and some improvements to the assessment methodology. The second update follows the same methodology to look back at changes in the reductions required over a 35-year period since 1990 at representative monitoring stations. Thirdly, the on-line mapping tool for the Farm and Landscape measures for Agriculture (FLAG) map (previously the Targeting Agricultural Measures map) has also been updated with monitoring data up to 2024, along with the other multiple lines of evidence used to indicate where agricultural measures are needed to restore water quality.
