2024 Quarter 4 Emissions Indicator Report Cover

Quarterly Greenhouse Gas Emissions Indicator Report 2024 Quarter 4

Year: 2025

This is the fourth EPA report in a new series of quarterly greenhouse gas emissions for Ireland to support more frequent monitoring of national and sectoral progress on climate action. The series will complement the national greenhouse gas inventory and projections prepared annually by the EPA. Emissions in quarter 4 2024 were up by 2.5 per cent on the same quarter last year. This was mainly driven by increased emissions from electricity generation (+11.3 per cent), and agriculture (+3.8 per cent). It should be noted that these data have been seasonally adjusted to provide a clearer picture of the underlying trends independent of seasonal fluctuations.

2024 Quarter 3 Emissions Indicator Report Cover

Quarterly Greenhouse Gas Emissions Indicator Report 2024 Quarter 3

Year: 2025

This is the third EPA report in a new series of quarterly greenhouse gas emissions for Ireland to support more frequent monitoring of national and sectoral progress on climate action. The series will complement the national greenhouse gas inventory and projections prepared annually by the EPA. Emissions in quarter 3 2024 increased by +0.5% (+60 kt CO₂ eq) compared to quarter 3 2023, driven mainly by increases in the Buildings (+162 kt CO₂ eq) sector (due to increased heating demand from cooler weather) and Agriculture (+99 kt CO₂ eq) sector (due to increased fertiliser use).

National Climate Change Risk Assessment Main Report

Year: 2025

Ireland’s first National Climate Change Risk Assessment (NCCRA) provides a comprehensive national overview of the potential risks and opportunities posed by climate change for Ireland. It will play a critical role in meeting national policy objectives and supporting sectoral and local authority climate adaptation planning processes. The NCCRA integrates scientific and technical knowledge with input from expert stakeholders, to identify, assess, and prioritise climate change risks to build a comprehensive understanding of risks.

Research 486: Proactive Optical Monitoring of Catchment Dissolved Organic Matter for Drinking Water Source Protection (PRODOM)

Authors: John Weatherill, Boris Droz, Elena Fernández-Pascual, Jean O’Dwyer, Emma Goslan, Connie O’Driscoll and Simon Harrison, May 2025

Year: 2025

In Ireland, approximately 82% of public water supplies originate from surface water catchments. This water requires disinfection with chlorine to inactivate pathogens and prevent the spread of waterborne disease. The presence of dissolved organic matter (DOM) in source waters can lead to the formation of potentially carcinogenic disinfection by-products (DBPs), such as trihalomethanes (THM4), of which Ireland has the highest number of reported exceedances in the EU in recent years. This research conducted detailed field and laboratory investigation in the River Lee catchment (Cork, Ireland), supported by predictive modelling using machine learning techniques, to gain more insights in the role of optically active DOM in DBP formation and forecasting. It highlights the value of UV-visible spectroscopy as a cost-effective and non-destructive technology suitable for proactive management of DOM in source water, with a high potential for aiding real-time process control at treatment plants.
