Residential

The Residential sector was responsible for 10.2% of Ireland's total Greenhouse Gas emissions in 2018

This section accounts for all emissions from fuel combustion in households for domestic space and hot water heating. Emissions in the Residential sector increased by 7.9% or 0.46 Mt of CO2eq in 2018 compared to 2017 emissions. Within the different fuels used in household space and water heating, all fuels showed increases; coal, peat, gasoil, kerosene, natural gas and biomass increased by 4.4%, 4.4%, 9.0%, 10.2%, 8.7% and 3.7% respectively in 2018 due to a colder winter with a higher heating demand.

Increased housing stock drove the gradual upward trend in the emissions from the Residential sector after 1998 following a sharp reduction in the early 1990s that resulted from fuel switching to reach a peak in 2010. The 2018 emissions in this sector are 7.9% higher than 2017 levels and are 17.6% lower than their 1990 level whereas the housing stock has increased by 77% in the same period. Winter heating demand is the most important variable determining emissions from this sector.

At the time of publication in June 2019 the emissions projections figures under the With Existing Measures scenario (which had the baseline inventory as 1990-2017), project emissions from the residential sector to decrease by 3% between 2018 and 2030 to 5.55 Mt CO2eq.

Under the With Additional Measures scenario (shown as the line in the graph below), emissions are projected to decrease by 21% between 2018 and 2030 to 4.55 Mt CO2eq.
