Hundreds of people have gathered in Dublin to march and demand that the Government delivers a "just climate action policy" and an end to fossil fuel power.
The national climate demonstration is part of a global day of action during the COP30 talks in Belém, Brazil.
"This climate march is shaping up to be the biggest that we've seen in Ireland this decade," said Siobhán Curran, Trócaire's Head of Policy and Advocacy.
"People are demanding that our leaders act quicker and stop prioritising polluting fossil fuel corporations. We owe this to the people around the world on the frontlines of this crisis who are experiencing hurricanes, flooding, wildfires and drought due to a climate crisis that they did not cause in the first place," Ms Curran said.
The demonstration is organised by the Stop Climate Chaos coalition - of which Oxfam Ireland, Trócaire, AMLÉ and more are members.
"We have over 60 groups represented here today, from environmental, students, families, faith-based groups, workers and unions, healthcare professionals and many more," said Stop Climate Chaos coalition coordinator Sara Hurley.
"No matter your age or interest, climate change is something that links us all. The Government can't turn a blind eye or get away with weak ambition. It's costing the state billions in fines and it'll cost people in ways that can't be quantified in euros. We need fast, fair and funded climate action," she added.
There were also calls for more affordable homes with a greater efforts to power and heat households with clean energy.
"The shift to clean energy is not just about reducing emissions: it’s about creating an equal society. When we invest in home retrofitting, renewable energy and community power, we lower costs, cut pollution, and create good jobs. Everyone benefits," said Sinéad Roche, Campaigns Coordinator of Oxfam Ireland.
Demonstrators said that the current measures are insufficient to address the scale and urgency of the climate crisis.
Students said environmental policy needs to place the protection of people and the planet at the centre of national decision making.
STAND, an organisation working with third-level students on global justice education, added: "We know students need warm, affordable homes and fair energy costs here in Ireland. Ten years on from the Paris Agreement, progress has been too slow. We’re calling for faster, fairer climate action that leaves no one behind."
