Emissions of NOx are currently well above the 2010 limit in the EU Directive on National Emissions Ceilings (NEC) and are expected to remain high in the short term, largely due to the difficulty in achieving significant reductions in emissions from road traffic. Ireland is non-compliant with 2010 national emission reduction commitments as a result of applying improved emission inventory methods updated in accordance with scientific knowledge. Consequently, under the NEC Directive 2016/2284 Ireland is allowed to use flexibility mechanisms to adjust NOx emissions. With the use of these flexibilities, Ireland exceeds the emission ceiling in 2010 and is compliant with the NOx emission ceiling from 2011 onwards. Ireland has new reduction commitments of 49% for 2020 and 69% for 2030 compared to 2005 levels. Further information can be found in Ireland’s Air Pollutant Emissions 1990-2030 report.
