Air pollutant emissions in Ireland are reported annually to the European Commission under the National Emissions Ceiling Directive and to the UNECE under the Convention on Long-Range Transboundary Air Pollution. These pollutants are responsible for long-range transboundary air pollution such as acidification, eutrophication and ground-level ozone pollution.
Data on five key air pollutants, Nitrogen Oxides (NOx), Sulphur Dioxide (SO2), Non-Methane Volatile Organic Compounds (NMVOCs), Ammonia (NH3) and Particulate Matter (PM2.5)are reported to the European Commission as required under the National Emissions Ceiling Directive on an annual basis. In addition, carbon monoxide (CO) and particulate matter (PM), heavy metals and persistent organic pollutants are reported under the UNECE’s Convention on Long-Range Transboundary Air Pollution every February.
An Informative Inventory Report (IIR) is available which describes the methodologies, input data, background information and the entire process of inventory compilation for air pollutants, as well as any improvements and recalculations of the inventories reported in previous submissions.
