Why Iceland and Others Might Want In, Not Out, of the E.U. Club

The prospect of Iceland joining the European Union has moved from a marginal curiosity to a serious policy discussion, reflecting a broader reassessment of the bloc’s appeal among smaller European economies. While the United Kingdom’s departure in 2020 signalled a high‑profile withdrawal, a growing number of states are now exploring accession, driven by a mix of economic pragmatism, geopolitical calculation and domestic political change. Iceland, with its modest population of around 380,000 and an economy heavily reliant on fisheries, tourism and renewable energy, exemplifies the nuanced motivations that are reshaping the EU’s enlargement narrative.In recent months, the Icelandic government has commissioned a series of impact studies to gauge the benefits and costs of membership..

Preliminary findings suggest that access to the EU’s single market could bolster the country’s export capacity, especially for high‑value fish products that already enjoy preferential treatment under the EU’s “green lane” arrangements. Moreover, participation in EU research programmes such as Horizon Europe would provide Icelandic universities and firms with expanded funding opportunities, potentially accelerating the development of its burgeoning carbon‑capture and geothermal sectors.At the same time, the political discourse in Reykjavík reflects a cautious optimism rather than unreserved enthusiasm. Critics warn that full membership would require the country to cede control over its fisheries policy, a sector that has long underpinned Iceland’s economic independence..

The EU’s Common Fisheries Policy (CFP) sets quotas and management rules at a supranational level, and while reforms are under discussion, the lack of a clear pathway for small‑state concessions fuels domestic scepticism. Nonetheless, proponents argue that the CFP’s gradual shift towards sustainability aligns with Iceland’s own conservation goals, and that a negotiated opt‑out or special status could be achieved, as has been the case for Norway and the United Kingdom in specific sectors.The broader European context offers further insight into Iceland’s calculations. Over the past five years, the EU has faced a series of crises—from the eurozone debt turmoil to the pandemic and the war in Ukraine—that have tested its cohesion but also highlighted its capacity for coordinated action..

The bloc’s collective response to energy security, through mechanisms such as the REPowerEU plan, has underscored the strategic value of shared resources and policy alignment. For Iceland, a nation that generates almost all of its electricity from renewable sources, integration into a larger energy market could open avenues for export of surplus power, particularly as European nations accelerate the phase‑out of fossil fuels.Parallel to Iceland’s deliberations, a string of countries in the Western Balkans, the Western Mediterranean and the Atlantic fringe are at various stages of accession talks. Croatia’s 2013 entry, followed by the more recent candidacy of Albania, North Macedonia, Montenegro and Serbia, demonstrates a sustained appetite for EU membership despite lingering concerns over democratic backsliding and rule‑of‑law standards..

Observers note that the EU’s willingness to keep accession tracks open, even while tightening conditionality, signals a strategic intent to maintain influence in its immediate neighbourhood and counter competing geopolitical actors, notably Russia and China.Economic incentives remain central to this dynamic. The EU’s structural and investment funds, which have supported infrastructure, digitalisation and climate projects across member states, represent a potent lure for economies seeking to modernise. For Iceland, participation could unlock billions in financing for upgrading its port facilities, expanding broadband coverage in remote communities and scaling up hydrogen production—a sector the country is keen to develop as a complement to its renewable electricity base..

Such investments would not only stimulate growth but also reinforce Iceland’s position as a niche exporter of clean‑energy technologies.Geopolitically, the shift is equally significant. The European Union’s foreign‑policy apparatus, embodied in the European External Action Service and the Common Security and Defence Policy, offers small states a platform to amplify their voice on the world stage. Iceland, despite its NATO membership, has traditionally pursued an independent diplomatic line, especially concerning Arctic affairs..

Full EU membership could afford Reykjavik a seat at the table in shaping the bloc’s Arctic strategy, thereby enhancing its influence over resource management, navigation rights and environmental protection in a region of increasing strategic interest.Domestic politics in Iceland have also evolved, with younger voters showing greater openness to European integration. Recent opinion polls indicate that support for EU membership has risen from single‑digit figures a decade ago to roughly a third of respondents favouring accession, while a similar proportion remains undecided. This shift reflects broader societal changes, including heightened awareness of climate change, a desire for greater international collaboration and a recognition of the limits of a small‑state economy operating in an increasingly interconnected world.Nevertheless, the path to membership is not without obstacles..

The EU’s enlargement criteria, set out in the Copenhagen criteria, demand stable democratic institutions, a functioning market economy and the ability to adopt the acquis communautaire in its entirety. While Iceland scores highly on governance and human‑rights indices, the alignment of its legal framework with EU standards—particularly in areas such as competition law, data protection and taxation—would require substantial legislative overhaul. Moreover, the EU’s own internal debates about enlargement fatigue and the capacity of its institutions to absorb new members could delay or complicate the accession process.Financial considerations also weigh heavily..

Membership entails the contribution of a national gross national income (GNI) share to the EU budget, which, for a small economy like Iceland’s, could amount to several hundred million euros annually. The trade‑off between this outflow and the inflow of structural funds, market access and other benefits is a key point of contention in parliamentary debates. Critics argue that the net fiscal impact may be negative in the short term, while supporters contend that long‑term gains from deeper integration and investment will outweigh the initial costs.The Icelandic case therefore illustrates a broader trend: a re‑evaluation of the European Union not as a monolithic entity but as a flexible partnership that can be tailored to the specific needs of prospective members..

The experience of Norway, which remains outside the EU yet participates in the single market through the European Economic Area, and the United Kingdom’s post‑Brexit negotiations on fisheries and financial services, provide precedents for nuanced arrangements. If Iceland can negotiate sector‑specific opt‑outs or transitional periods, it may mitigate the most contentious aspects of integration while still reaping the bulk of economic and geopolitical benefits.In sum, the conversation surrounding Iceland’s potential EU membership reflects a complex interplay of economic incentives, political aspirations and strategic calculations that extend beyond the island nation itself. As the European Union continues to navigate internal reforms and external pressures, its openness to new members—especially those that bring complementary strengths in renewable energy, fisheries sustainability and Arctic expertise—could shape the bloc’s future trajectory..

For Iceland, the decision hinges on.
