Introduction
Amidst growing climate displacement globally and shifting political realities, the European Union is uniquely well-positioned to take a leadership role in addressing climate mobility. As climate impacts intensify worldwide, there is growing recognition that our world needs more systematic, comprehensive, and equitable approaches to fund both immediate and long-term climate mobility needs.
Recent changes in United States policy have dramatically altered the funding landscape. With obligations for the 2025 fiscal year 84 percent lower than 2024,Footnote 1 a sizable gap has emerged in climate mobility financing. Simultaneously, growing national security concerns, particularly the war in Ukraine, have prompted several European countries to reallocate funds toward defense spending,Footnote 2 often at the expense of development and climate initiatives.Footnote 3
These political shifts and the resulting competing funding goals coincide with structural constraints on EU member states, which must operate within strict limits on public debt and government deficit. As individual countries face increasing financial pressures, development aid generally and climate mobility financing specifically suffers. The EU as an institution, however, is not subject to these same borrowing constraints, allowing it greater flexibility than its member states.
Given this newly emerged funding gap and growing financial pressures on many traditional donor countries, a more cohesive, strategic, and coordinated response to climate mobility has become imperative. This essay argues that the EU—distinct from its individual member states—is uniquely well-positioned to lead such an effort through its proven commitment to climate action, existing legal mandate, substantial resources, institutional coordination capacity, and technical implementation capabilities. Combined with its coalition-building experience, the EU is positioned to lead the way in developing a cohesive and impactful strategy to climate-induced mobility challenges.
The EU’s Track Record in Financing Climate Mobility
The EU has demonstrated substantial financial commitment to a green future, including climate mobility programming. It has pledged to mobilize at least €1 trillion in sustainable investments over the next decade,Footnote 4 while allocating 30 percent of its current multi-annual budget and 37 percent of the NextGenerationEU (NGEU) instrument specifically to green investments.Footnote 5 The EU’s climate finance contributions have grown dramatically, nearly tripling in a decade. Together with its twenty-seven member states, the EU stands as the world’s largest provider of climate and development finance.Footnote 6 The EU’s public funding to help developing countries combat and adapt to climate change rose from €9.6 billion in 2013 to €28.5 billion in 2022, maintaining this level with €28.6 billion in 2023.Footnote 7 Since many contributions are integrated into larger climate or development packages, the first part of the analysis reviews both EU-spearheaded initiatives and its recent contributions to funds specifically related to climate mobility.Footnote 8
Contributions to Prevent or Minimize Climate-Induced Displacement
Development aid and infrastructure financing both play crucial roles in reducing exposure to climate impacts and preventing displacement.Footnote 9 The EU approaches this challenge through a two-pronged approach: direct EU-led initiatives and strategic contributions to multilateral funds.
In 2021, the EU launched its flagship Global Gateway initiative, an investment strategy that explicitly incorporates climate mobility considerations into infrastructure development.Footnote 10 As an institution, the EU ranks third among the Development Assistance Committee providers of the Organisation for Economic Co-operation and Development (OECD).Footnote 11 This EU-led program coordinates resources from the Union, its member states, and their financial institutions to mobilize up to €300 billion in investments by 2027.Footnote 12 The partnership program of Global Gateway aims to support the design and implementation of sustainable projects that may deliver lasting social and economic benefits to local communities while avoiding unsustainable levels of debt.Footnote 13
Beyond its direct initiatives, the EU contributes substantively to multilateral initiatives in the migration-development nexus. Collectively, the twenty-seven EU countries provide 55 percent of global development assistance,Footnote 14 and nearly half of all the World Bank’s International Development Association funding.Footnote 15 The EU also supports specialized programs such as the Horn of Africa Umbrella Program and the Global Facility for Disaster Reduction and Recovery.Footnote 16 While only a small percentage of these contributions fund climate mobility efforts, they are nonetheless noteworthy.
The Green Climate Fund has received significant EU support since its 2010 establishment.Footnote 17 The EU alone pledged nearly half of the Fund’s initial $10.3 billion capitalization, with member states contributing an additional $4.7 billion. During the 2019 replenishment, primarily EU countries committed $9.78 billion over four years, with the EU disbursing $5.5 billion by May 2022.Footnote 18 Importantly for climate mobility, the Fund has developed specific investment criteria for mobility-related projects, now integrated into its broader climate finance mechanism.Footnote 19
Climate adaptation financing serves as another critical strategy for reducing migratory pressures.Footnote 20 EU countries have been providing outsized proportions of annual voluntary pledges to the Adaptation Fund,Footnote 21 which the European Commission bolstered at COP26 in 2021 with a significant €100 million commitment.Footnote 22 This overwhelming support for adaptation funding demonstrates the EU’s commitment to addressing climate mobility through prevention rather than solely through post-displacement responses.
Contributions to Address Climate-Induced Displacement
In addition to efforts to prevent and minimize climate-induced displacement, the EU has also developed significant capacity to respond to such displacement after movement has happened. A landmark achievement in this area came with the establishment and operationalization of the Loss and Damage Fund at COP28 in 2023. The EU and its member states have since contributed more than €400 million, representing over two-thirds of initial funding pledges.Footnote 23 The Loss and Damage Fund breaks new ground by explicitly including displacement, planned relocation, and migration within its scope—the first climate fund to specifically designate human mobility as a thematic area.Footnote 24
The EU complements its structural financing efforts with targeted humanitarian support for climate-affected populations.Footnote 25 In Turkey alone, the EU has allocated €3.48 billion in humanitarian funding since 2012, including €78.2 million specifically for earthquake response—demonstrating the EU’s capacity to mobilize rapid funding for climate and disaster displacement.Footnote 26 A key partnership in the EU’s humanitarian strategy is with the UN Refugee Agency (UNHCR).Footnote 27 The European Commission has consistently ranked among the UNHCR’s top three global donors.Footnote 28 The Commission’s support covers the full displacement cycle—from emergency response to integration and return programs—though its tightly earmarked contributions currently prioritize conflict-affected communities rather than climate displacement specifically.Footnote 29
The EU’s Unique Position to Take the Lead on Climate Mobility Financing
While several EU member states have distinguished themselves in making climate finance commitments—with Luxembourg, Sweden, Germany, and Denmark each surpassing the United Nations’ 0.7 percent target for development assistance in 2023Footnote 30 and Germany,Footnote 31 France,Footnote 32 and SwedenFootnote 33 standing out in real-term contributions—individual country efforts face mounting constraints.
Economic headwinds are intensifying these challenges. Despite the EU’s groundbreaking NGEU program,Footnote 34 post-pandemic economic recovery remains sluggish across the continent, with stagnation or contraction in several economies.Footnote 35 Compounding these difficulties are looming U.S.-imposed tariffs on European exportsFootnote 36 and newly emerged security concerns prompting increased defense spending that often comes at the expense of foreign aid allocations.Footnote 37 Most critically, member states must operate within strict public debt and government deficit limits under the EU’s Stability and Growth Pact, curtailing their financial flexibility.Footnote 38
The EU, however, is uniquely well-positioned to fill this emerging leadership gap in climate mobility financing. It possesses four crucial advantages that its individual member states lack.
First, unlike its member states, the EU is not subject to the same borrowing constraints and has recently demonstrated greater flexibility in fiscal rules in response to multiple crises.Footnote 39 Importantly, the EU can leverage its collective borrowing capacity through novel joint debt instruments such as Eurobonds,Footnote 40 potentially mobilizing significant new funding streams—estimated at up to $800 billion annuallyFootnote 41 —to offset decreasing state-level contributions.Footnote 42 Second, the EU possesses the legal mandate to lead on climate mobility financing through its shared competence with member states on climate action.Footnote 43
Third, as illustrated in the previous section, while the EU has made substantial contributions across multiple climate mobility initiatives, current inefficiencies due to insufficient donor coordinationFootnote 44 and incoherence of initiatives and frameworksFootnote 45 are becoming increasingly problematic amid funding cuts. The EU has demonstrated the institutional capacity to organize coordinated, streamlined frameworks,Footnote 46 as evidenced by its pioneering regulation in privacy and digital technologies and dominance in antitrust.Footnote 47 Finally, the EU’s proven coalition-building abilities in international climate negotiations position it ideally to develop the multilateral cooperation essential for addressing current and future challenges.
Conclusion
Recent political shifts in traditional donor countries have created uncertainties in the global climate finance landscape. As traditional funding sources contract and member states face increasing constraints, the EU’s institutional role in financing climate mobility becomes increasingly vital. The EU has demonstrated both the commitment and capability to lead in this space. With its unique advantages of fiscal flexibility, legal mandate, institutional coordination abilities, and coalition-building experience, the EU is positioned to develop the cohesive, strategic response that climate mobility financing urgently requires. As climate impacts intensify and displacement pressures grow, the EU’s leadership will become essential for developing sustainable solutions to climate-induced mobility challenges that protect the most vulnerable communities worldwide.
