Ireland has rapidly emerged as a dynamic hub for clean and green tech innovation, driven by a potent mix of entrepreneurial spirit, academic excellence, and strong public-private collaboration.
With its ambitious climate targets and supportive policy frameworks, Ireland is fostering a new generation of start-ups tackling environmental challenges with ingenuity and impact.
From carbon capture and circular bioeconomy solutions to smart energy systems and sustainable agriculture, Irish innovators are developing technologies that not only reduce emissions but also create new economic opportunities.
“As global demand for climate solutions intensifies, Ireland’s start-ups are increasingly attracting international attention and investment”
The presence of world-class research institutions, such as Trinity College Dublin, University College Dublin, University College Cork and University of Galway, has helped incubate breakthrough companies like NEG8 Carbon and BioNua, while accelerators like Bord na Móna’s Accelerate Green and Enterprise Ireland’s Innovation Arena are providing vital funding and mentorship.
Ireland’s clean tech ecosystem is also notable for its diversity – spanning marine biotech, EV infrastructure, AI-powered sustainability platforms, and second-life battery applications. Many of these ventures are female-led or socially driven, reflecting a broader commitment to inclusive and responsible innovation.
As global demand for climate solutions intensifies, Ireland’s start-ups are increasingly attracting international attention and investment. Whether through pioneering carbon mineralisation, transforming food waste into energy, or revolutionising packaging with mycelium-based materials, these companies are positioning Ireland as a leader in the green transition.
