Summary: 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.
