Green Financing

We are demonstrating our commitment to financing projects that will support our Net Zero Future ambition. In 2019, we issued Ireland's first corporate public green bond and have issued a number of subsequent green bonds since our inaugural issue. At 30 June 2023, 17% of total debt was made up of green bonds. We were also the first Irish utility to have a syndicated sustainability linked loan.

ESB's Green Bond Framework

ESB considers that Green Bonds are an effective tool to channel liquidity into assets which facilitate the transition to low carbon electricity generation and reduce greenhouse gas emissions and therefore support our Net Zero by 2040 strategy. 

We believe that Green Bonds offer transparency to investors who wish to allocate funds to green assets, and in doing so support ESB’s transition to reliable, affordable, low carbon energy as well as adding a further diversity to ESB’s investor base.

We use the net proceeds of our green bonds to finance eligible projects according to the ESB Green Bond Framework

ESB further demonstrated its commitment to financing projects that will significantly drive a renewable energy future by becoming the first Irish utility to have a syndicated sustainability linked loan.

The €1.4 billion, five-year loan has been provided by 14 international banks, with BNP Paribas acting as Sustainability Coordinator – represents a second major statement by ESB Treasury to deliver renewable projects with the support of the sustainable finance markets.

The key deliverables associated with the loan are directly linked with the Irish Government’s Climate Action Plan and are aimed at reducing carbon emissions from ESB’s generation fleet while increasing the amount of energy produced from renewable technologies.

ESB also continues to focus on producing clean, secure and affordable energy – delivering smart, reliable, resilient networks to enable the connection of more renewable generation and development of major green projects including onshore and offshore wind, solar and investment in the electric vehicle charging infrastructure.

ESG and Sustainability Responsibility

Our annual sustainability reports along with our annual CDP score report outline how ESB is performing against sustainability targets.

Our reporting is guided by the principles of materiality, inclusiveness and responsiveness. We use leading standards and methodologies for reporting, such as the Greenhouse Gas Protocol, CDP and the Global Reporting Initiative (GRI). This report has been prepared in accordance with the GRI Standards Core option and has been independently assessed by DNV against this option.

All our reporting is available in our dedicated ESG Hub here.
