Latest emissions data

Ireland’s latest greenhouse gas (GHG) emissions 1990-2019 are final figures based on the SEAI’s final energy balance released in November 2020.

In 2019, Ireland’s GHG emissions are estimated to be 59.78 million tonnes carbon dioxide equivalent (Mt CO2eq), which is 4.4% lower (or 2.75 Mt CO2 eq) than emissions in 2018 (62.53 Mt CO2 eq). There was a small increase of 0.7% in emissions reported for 2018 compared to 2017. Emissions reductions have been recorded in six of the last ten years of inventory data (2009-2019). In 2019 national total emissions decreased by 4.4%, emissions in the stationary ETS sector decreased by 8.7% and emissions under the ESD (Effort Sharing Decision) decreased by 3.0%. This is the first time all 3 category totals have decreased in the same year since 2013.

Ireland’s greenhouse gas emissions decreased by 4.4% (2.75 Mt CO2eq) in 2019 compared to 2018 with decreases observed in all sectors except for commercial services and public services. These 2 sectors showed small increases in emissions (+1.8% and +1.2% respectively), shown highlighted red in the "Emissions change 2018-2019" table below.

These decreases in emissions is a small step on the road to achievement of Ireland’s long-term decarbonisation goals.

Arresting growth in emissions is a challenge in the context of a growing economy but one which must continue to be addressed by households, business, farmers and communities if Ireland is to reap the benefits of a low-carbon economy.

Assessment of compliance

The table below shows the assessment of compliance under the European Union's Effort Sharing Decision which sets 2020 targets for sectors outside of the (EU ETS) and annual binding limits for the period 2013-2020. The years 2013-2018 have been reviewed and compliance agreed by the European Commission under Article 19 of the MMR No. 525/2013. Ireland has exceeded its Effort Sharing Decision annual limit for 2016, 2017 and 2018 and provisional estimates indicate an exceedance of 6.85 Mt CO2 eq for 2019. In contrast to sectors in the EU ETS which are regulated at EU level, Ireland is responsible for national policies and measures to limit emissions from the sectors covered by Effort Sharing legislation. Further information can be found on the European Commission website on Effort Sharing and emission targets.

Greenhouse gas emissions share by sector in 2019

EU/EA member states GHG emissions per capita

As the graph below shows Ireland has higher than average emissions of methane (CH4) and nitrous oxide (N2O) because we have the highest agriculture emission contribution from any of the EU member states. A similar pattern can be seen in New Zealand where agriculture is also an important part of the economy. These figures reflect the relative importance of agriculture to Ireland’s economy, and the lack of heavy industry in comparison to some other member states. Agricultural emissions are dominated by CH4 from enteric fermentation and manure management and N2O from fertiliser, manure applied to land and animal excreta deposited directly onto pasture. The graph below is based on 2019 data, which is the most recent available on the EEA data viewer.
