Bank of Ireland has issued its second green bond of 2025, raising €750 million amid high investor appetite for sustainable finance. The ten-year fixed-rate bond, priced at 3.625%, attracted orders of more than €2.6 billion from over 140 global investors — the strongest response since the bank’s first green bond in 2021.

Proceeds will be directed under the bank’s green finance framework, funding renewable energy projects, energy-efficient buildings, and sustainability-linked loans. This aligns with Ireland’s broader ambition to scale green investment and support the low-carbon economy.

Mark Spain, the bank’s Chief Financial Officer, said the offering demonstrates investor confidence in the group’s sustainable finance strategy. The funds will further expand initiatives such as green residential mortgages, sustainability-linked lending for SMEs and farmers, and financing for wind and solar projects across Ireland.

Bank of Ireland’s sustainability-linked lending reached €16.5 billion by the end of September 2025, surpassing its €15 billion annual target ahead of schedule. The bank expects to double this to €30 billion by 2030. Earlier this year, it financed its first domestic solar power project and extended its Enviroflex loan scheme to tillage farmers, broadening access to climate-related funding across sectors.

The bond issuance was jointly led by Davy, BofA Securities, ING, J.P. Morgan, Mizuho, and NatWest. It represents one of the largest green financing transactions in Ireland this year, reinforcing the financial sector’s central role in achieving national sustainability objectives.

The transaction also highlights a continued tightening of spreads in green bond markets, suggesting that sustainability-linked assets are gaining strength among institutional investors.
