Our sustainability commitments
As a leading utility provider, we have a responsibility to help deliver an energy system that is secure, affordable and increasingly sustainable. In response to changing stakeholder expectations and the opportunities presented by the energy transition, we refreshed our sustainability approach in 2025. We also transitioned from SDG Champion to SDG Ambassador, reaffirming our commitment to advancing sustainable development within our organisation and across wider society.

Abbotstown biodiversity project
This initiative at our gas installation site in Co. Dublin saw a grassland site transformed into a biodiverse home for local flora and fauna. It is a practical example of how Gas Networks Ireland’s 'Planet, People and Principles’ commitments can be embedded into day-to-day operations, leaving a positive environmental legacy for future generations.
Sustainable development
Underpinning our sustainability activity is our dedication to progressing the UN Sustainable Development Goals. In 2025, we transitioned from our role as the Department of Climate, Energy and Environment's SDG Champion to an enduring position as SDG Ambassador. This role involves actively promoting the SDGs within our organisation, across the wider energy sector, and in communities where we operate. As an Ambassador, we are committed to supporting all 17 SDGs, while especially championing the six goals most relevant to our business.
