Ireland's GHG Emissions

Agriculture remains the single largest contributor to the overall emissions at 33.3% of the total. Transport and Energy Industries are the second and third largest contributors at 19.8% and 19.3 % respectively. The graph below illustrates the trend in these GHG emissions over the period 1990-2017, where it can be seen that there is evidence of an upward trend in some sectors in recent years. The latest emissions publications are available on the EPA Website and details from 2017 can be viewed here.

Residential emissions decreased by 5.0%, the equivalent of  0.30 Mt CO2eq in 2017 due to a milder  winter.. Within the different fuels used in household space and water heating, gasoil increased by 3.6% whereas kerosene use decreased by 5.2%,  and natural gas by 1.3%, whereas coal and peat use continued to decline by 16.8% and 4.3% respectively in 2017 (EPA, 2019)


Waste emissions decreased by 2.5% in 2017, with decreases in sub category; landfills of 3.4%. Overall emissions decreased by 0.02 Mt CO2eq. 

Energy Industries sector showed a decrease of 6.9% which is attributable to an decrease of  5.9% fossil fuel consumption (21.2% decrease in coal and 6.2% decrease in peat) in 2017 and an increase of 21.1% and 1.6% respectively for electricity generated from wind and hydro renewables in 2017 (EPA, 2019).  Renewables now account for 29.6% of electricity generated in 2017 (up from 25.5% in 2016). Ireland exported 2.3% of electricity generated in 2017. In 2017, total final consumption of electricity increased by 1.1% (EPA, 2019).
