Summary: The EPA has launched 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. The data from the first three months of this year show an overall reduction of 2.2 per cent compared to quarter 1 2023, and a 0.2 per cent increase on quarter 4 2023. It should be noted that these data have been seasonally adjusted to provide a clearer picture of the underlying trends independent of seasonal fluctuations.
