The existing gas network will deliver least cost and least disruptive decarbonisation of Ireland's heating sector.
A pathway to 2050
Domestic heating accounts for 9% of Ireland's total CO₂ emissions. Equal to almost 6Mt CO₂.
Immediate emissions saving achievable by converting 300,000 homes from oil to natural gas
Emissions savings possible per annum by 2050 in the heating sector using the gas network
Natural gas provides a significantly cleaner alternative to coal, oil and peat heating today and as renewable gas is introduced, the homes and businesses connected to the gas network will decarbonise.
- Did you know?
Using renewable gas does not require any change to the gas infrastructure or domestic heating systems.

- Did you know?
Converting the 300,000 homes on or near the natural gas network to natural gas would immediately save 0.3Mt CO₂/annum.

Why gas and the gas network provide a smart solution to decarbonising heating.
It is 3 times cheaper to use the gas network to decarbonise heating for the 1 million homes located on or close to the network.
Delivering renewable gas to homes and businesses will help Ireland increase renewable energy use in the heating sector.
Our vision to decarbonise heat
Short to medium term
Convert the 300,000 homes near the gas network from oil to gas. This will reduce CO₂ emissions by 0.3Mt/annum and the carbon intensity of these homes by 30%.
Use the gas network to deliver renewable gas into 1 million homes in Ireland. This way, the heating sector can be decarbonised at scale.
An appropriate support scheme
The inclusion of renewable gas in the Support Scheme for Renewable Heat (SSRH) is critical for the development of renewable gas projects in Ireland.
Building regulation amendments
To create a level playing field for renewable gas, Part L of the building regulations should be amended to include appliances fuelled by a gas blend containing renewable gas. Building Energy Rating (BER) certification for the domestic sector should also include the option to select renewable gas.
Technology neutral approach
Gas and the gas network can deliver immediate emissions reductions for Ireland. Longer term, emerging technologies can deliver further reductions. Limiting the choice of technologies now could have negative long-term consequences.
Decarbonising Domestic Heating in Ireland
Ervia commissioned KPMG to develop and evaluate a number of scenarios for the decarbonisation of the one million Irish residential homes currently connected, or within close proximity, to the existing gas network. Ireland has an ambitious vision to transform into a low carbon society and economy by 2050. While significant progress has been made to date in the decarbonisation of industrial energy and electricity generation, there is a recognition that more can, and must be done to address other areas such as heating and transport, which also generate significant volumes of greenhouse gases. This report focuses on one of these areas, namely the decarbonisation of the residential heating sector.Download the report
