The Shared Island Fund and Cross-Border Digital Projects
On this page
The Shared Island Fund is the Government’s all-island investment programme, funding projects that connect Ireland and Northern Ireland in practice: research, infrastructure, education, and enterprise. For businesses, the most relevant current instrument is the Shared Island Sustainability Challenge Fund, whose call for applications was launched on 12 October 2026 by the Taoiseach and Ministers, worth EUR 26 million for cross-border sustainability projects.
What the Sustainability Challenge Fund is
A EUR 26m fund for cross-border sustainability research and innovation, opened for applications in October 2026. The defining requirement is cross-border partnership: organisations on both sides of the border working jointly, which is also the point of the fund, building the all-island economy through real projects rather than speeches.
Where digital projects fit
Sustainability projects are increasingly digital: shared monitoring platforms, data systems for environmental management, smart energy, and digital services used on both sides of the border. If your project has a digital core and a cross-border partner, it is in the conversation, and the digital sustainability guide covers the technical side of what gets funded.
How to approach it
- Find the partner first. The cross-border requirement is non-negotiable, so the partnership comes before the application.
- Check the open calls. The Shared Island unit publishes on gov.ie, and the Department of the Taoiseach and Enterprise Ireland announce calls, as on 12 October 2026.
- Scope the digital core properly. Funders reward projects with a real, buildable technical component, not a vague website line item.
- Budget honestly. Reimbursement-based funding punishes optimistic budgets; cost the build properly, the way we do in grant-ready project scoping.
The bigger picture
Shared Island funding is one of several cross-border and all-island instruments; the full landscape, including LEO and Enterprise Ireland supports, is in our digital grants guide. The pattern for 2026 is consistent: sustainability plus digital plus partnership is the formula the State is funding.
