We are committed to open and transparent reporting on all sustainability topics relevant to our business. In the medium term, ESB aims to fully utilise the useful framework of CSRD to report on our material sustainability topics. We note the European Commission’s proposal to delay implementation of CSRD, and associated revision to the reporting requirements, and in the interim we are committed to continuing to provide comprehensive sustainability reporting on a voluntary basis.

Ireland's pathway to a net zero energy system by 2050
This ESB report sets out our vision for Ireland’s 2050 energy future, looking at what’s needed for a secure net zero system across electricity, heating, transport and industry.
ESB plays a central role in ensuring this vision becomes reality for a growing, thriving Ireland.
Through electricity as an enabler of regeneration, we are driven to make a difference for planet, place and people. This summary of our Sustainability Leadership Plan sets out our key ambitions and the actions we will take, as they relate to these three pillars.
Our Net Zero Pathway Report outlines how we are working towards achieving our strategic ambitions by 2040, along with intermediate reduction targets and Strategic Performance Initiatives (SPIs). It also sets out the initiatives being undertaken by us to support decarbonisation across society more broadly.
This year’s report is presented in the context of our Sustainability Leadership Plan, highlighting the data sets and performance, across three pillars including planet, place and people. The production of the data disclosures report has functioned as an interim step towards CSRD aligned reporting for the 2025 calendar year.
A key focus of our Net Zero to 2040 Strategy is empowering our people to deliver ion our ambitious objectives with a strong values-based and inclusive culture. With the aim of creating a more inclusive workplace, we published our first Gender Pay Gap report in 2021 before the Gender Pay Gap Information Act 2021 came into effect. Linked is our 2025 report with all details.
CDP is a not-for-profit charity that runs the global disclosure system for investors, companies and others to manage their environmental impacts. We have disclosed our emissions, emission reduction initiatives and climate risk management approach via CDP since 2009. In 2024, we scored a B Management score for our climate change questionnaire disclosure.
We are assessed by several sustainability rating agencies with these ratings an increasingly important consideration for our investors and stakeholders.
