Ó Cathasaigh has been a Green Party TD for Waterford since 2020. He is the party spokesperson for social protection, and was a member of Waterford City and County Council from 2019 to 2020. Before becoming a TD, he worked as a primary school teacher.

The reality of climate change and biodiversity loss is playing out on our TV screens in real time. I entered politics to secure a better future for my children, and that imperative to change has never been more clear or more urgent. Making that positive change is the reason I'm running.

Facing up to climate change is the challenge of our generation. We have made real positive progress in the last government, and the opportunity for Ireland to be leaders in this space is huge.

Waterford! And not just as a local politician - Waterford is a great example of the opportunity we have, if we can capitalise on it. Investment in public transport, development of renewable energy, balanced regional development - these are core objectives set out in the Green Party manifesto, and Waterford is a prime area for each of those to be put into practice.
