Date released: June 03, 2021
3rd June 2021: The Environmental Protection Agency (EPA) today published a compliance assessment for emissions of five key air pollutants which impact air quality, health and the environment. The pollutants, which are subject to current and future emissions ceilings under the EU National Emissions Ceiling (NEC) Directive, are:
Emissions of other air pollutants and heavy metals not subject to NEC Directive ceilings are also reported on.
This latest report shows that, despite decreasing in 2019, ammonia emissions are still non-compliant with the EU ceiling and have now been non-compliant for 7 out of the last 9 years. Agriculture dominates emissions of ammonia (99 per cent), which arise from animal manures and nitrogen fertiliser. However, there are some encouraging signs of abatement measures being adopted at farm level, with approximately 16 per cent of cattle slurries applied using low emission spreading techniques, avoiding over 3,000 tonnes of ammonia emissions. There was also a four-fold increase, albeit from a low base, in the use of inhibited urea fertiliser products in 2019.
Emissions of nitrogen oxides - primarily from transport and diesel fuelled vehicles in particular - decreased by 9.2 per cent in 2019 as vehicle NOx abatement technologies continue to improve. Emissions of non-methane volatile organic compounds also decreased slightly (1.1 per cent) in 2019. These mostly arise from spirit production in the food and beverage industry, animal manures and fertilisers.
There was a 13.1 per cent decrease in emissions of fine particulate matter due to lower heating requirements in 2019, while emissions of sulphur dioxide continued on a downward trend. Ireland is compliant for 2019 with the emissions ceilings under the NEC Directive for nitrogen oxides, non-methane volatile organic compounds and sulphur dioxide, whilst a ceiling for fine particulate matter doesn’t come into force until 2020.
Sharon Finegan, Director of the EPA’s Office of Environmental Sustainability said:
“Emissions of all air pollutants need to reduce further to protect air quality and health and achieve compliance with EU emissions limits. The National Clean Air Strategy, which is currently being finalised, needs to set out the proposed measures to reduce emissions.
It is encouraging to see ammonia emissions beginning to be addressed at farm level. The assessment shows that Ireland can comply with the 2030 ammonia ceiling but this requires full implementation of measures in the Department of Agriculture’s AgClimatise strategy, and the National Air Pollution Control Programme. ”
Emissions of Sulphur dioxide, particulate matter, ammonia and nitrogen oxides are projected to be compliant with more challenging EU emission ceilings that will apply for 2030, provided planned measures are fully implemented.
Stephen Treacy, EPA Senior Manager said:
“Ireland has seen big reductions in the emissions of many air pollutants over the last thirty years, including a 94 per cent fall in Sulphur dioxide emissions and an over 60 per cent drop in fine particulate matter emissions. Further emissions reductions are possible with the right measures in place.
These measures are far reaching and require big changes in the Agriculture, Transport and Energy sectors including switching to cleaner fuels, technology improvements in slurry application and a significant uptake of electric vehicles. Further measures are required to reduce Non- Methane Volatile Organic Compounds emissions to meet the 2030 ceiling for this pollutant.”
These figures take account of the immediate short-term impact of COVID-19 in 2020 and in the first half of 2021.

Notes to Editor
UNECE Convention on Long-Range Transboundary Air Pollution (LRTAP)
The LRTAP Convention of 1979 was the first international treaty to deal with air pollution on a broad regional basis. The 32 signatories to the Convention agreed the principles of international cooperation for air pollution abatement. The number of substances covered by the Convention and its protocols has been gradually extended over time, notably to include ground-level ozone, persistent organic pollutants, heavy metals and particulate matter. Although Ireland hasn’t yet ratified the Gothenburg Protocol setting out national commitments to abate acidification, eutrophication and ground-level ozone, the European Union has, and binding national emission ceilings for Ireland are specified in the EU transposition of the Protocol, the National Emissions Ceiling Directive.
National Emissions Ceiling Directive
Directive (EU) 2016/2284 (replacing 2001/81/EC) ‘on the reduction of national emissions of certain atmospheric pollutants’ sets national emission reduction commitments for Member States and the EU for five important air pollutants: nitrogen oxides, non-methane volatile organic compounds, sulphur dioxide, ammonia and fine particulate matter. The new NEC Directive, which entered into force in December 2016, sets 2020 and 2030 emission reduction commitments for five main air pollutants. It also ensures that the emission ceilings for 2010 - set in the earlier directive - remain applicable for Member States until the end of 2019.
Ireland’s unadjusted emissions of nitrogen oxides and non-methane volatile organic compounds exceed the current ceilings, due to use of better scientific data which was unavailable when the ceilings were set. As a result, Ireland is adjusting the emissions of these pollutants to achieve compliance, as allowed under Article 5(1) of the NEC Directive
