Climate Change in the Irish Mind Wave 2 Insight Report Number 3 Climate Literacy
How does knowing that humans are the main cause of climate change affect your climate literacy, perspective on climate change, support for climate policies?, December 2025
Year: 2025
The ‘Climate Change in the Irish Mind’ project (CCIM) is a nationally representative study of the Irish people’s beliefs, attitudes, policy preferences and behaviours regarding climate change, undertaken by the EPA and the Yale Program on Climate Change Communication. The CCIM Insight report “Climate Literacy” investigates how the public’s understanding of human caused climate-change connects to their overall climate knowledge, their support for climate policies, and their views on climate change.
Extended Per- and Polyfluoroalkyl Substances (PFAS) monitoring at targeted inland surface water sites 2024
Year: 2025
Per- and poly-fluoroalkyl substances (PFAS) are a large group of man-made chemicals widely used in industrial and consumer products due to their water and oil resistance, chemical and heat stability, friction reduction and surfactant properties. They can be found in many everyday products, including outdoor clothing and in fire-fighting foams but can have harmful effects on human health and the environment.

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.
