ESB is committed to shaping a sustainable and secure energy system for the customers and communities we serve. Our 2025 Sustainability Report provides in-depth data and shares stories on how we are delivering today to make this happen – not just for us, for future us.
It is our first report aligned with the Corporate Sustainability Reporting Directive (CSRD), a voluntary step we are taking to bring a new level of transparency to how we communicate our progress and the challenges we face as we work to embed sustainability right across our business.

The report features an in-depth discussion with our Chief Executive Paddy Hayes and Group Head of Sustainability Sharon McManus, as they reflect on ESB's sustainability journey in 2025.
From the challenges brought by more frequent extreme weather, to new milestones reached in offshore wind and solar generation, and measures taken to support customers and communities around Ireland - read their insights into the challenges and opportunities that lie ahead.
CSRD reporting goes beyond sharing details of our own operations. It requires us to identify and evaluate material impacts, risks and opportunities right across the value chain. Our report presents a detailed overview of ESB’s value chain and where sustainability impacts arise.

To prepare for CSRD reporting, we carried out a ‘double materiality assessment’ – examining all aspects of our value chain to identify 1) external factors that have a material impact on our business, and 2) those areas where our operations have a material impact on the world around us. Through this process we identified a number of material topics across the pillars Environment, Social, and Governance.
