Climate Change Is Not Just Melting Ice—It's Threatening European Health Like Never Before
In her 2025 State of the Union address, President von der Leyen made one thing abundantly clear: the European Union is ready to take the lead on global health issues, stepping up in areas where others hesitate. But here's where it gets controversial—Europe itself is increasingly feeling the brunt of climate-related health threats, and the challenges are far from simple.
Extreme weather events, from soaring heatwaves to sudden floods, are just the tip of the iceberg. A less obvious but equally alarming trend is the rise of vector-borne diseases such as West Nile Fever and Chikungunya, infections that were once rare in Europe but are now emerging with alarming frequency. These changes place a growing strain on vulnerable populations, including pregnant individuals and older adults, and exacerbate issues tied to Europe's aging demographics, rising healthcare costs, and persistent gender health disparities.
The expansion of disease-carrying vectors, like Aedes mosquitoes, is driven not just by climate change but also by urbanization, global mobility, and environmental disruption. Regions that previously had little risk are now increasingly vulnerable to outbreaks. And this is the part most people miss: the EU Medical Countermeasure Strategy explicitly identifies these vector-borne diseases as a potential pandemic threat, pledging to integrate them into future climate adaptation and health security plans. This moment presents the EU with a unique chance to prioritize such threats in the upcoming budget cycle.
Investing in global health isn’t just about altruism—it’s a strategic move to safeguard European health security while boosting competitiveness. Yet the EU still faces fragmented health preparedness among its Member States, coupled with underinvestment in crucial research and innovation (R&I). The upcoming Multiannual Financial Framework (2028-2034) could be a turning point, embedding a robust global health dimension into Horizon Europe.
However, recent reductions in official development assistance and a retreat from multilateral engagement are weakening the global health security architecture, disproportionately impacting low- and middle-income countries. These nations, already heavily affected by climate-induced health challenges, risk further setbacks in controlling neglected vector-borne diseases like Dengue, Zika, and Chikungunya. Without international cooperation, these gaps will only widen.
To address this, the EU must intensify partnerships, especially with African nations, focusing on strengthening health systems and scaling up R&I capacities through aligned policies, regulatory support, and technology transfer. This approach aligns with the Global Health Strategy and the EU-AU Innovation Agenda. Continuation and expansion of proven initiatives—such as the European and Developing Countries Clinical Trial Partnership (EDCTP3) and the Team Europe Initiative on Manufacturing and Access to Vaccines, Medicines, and Health Technologies (TEI MAV+)—should be guaranteed in the next MFF.
Here’s a bold point to consider: supporting global health isn’t just solidarity—it’s a smart investment. According to a study by Impact Global Health, every euro a high-income country invests in global health R&I yields a sevenfold return domestically. How? By creating skilled jobs, encouraging private-sector co-investments, stimulating innovation ecosystems, and building scientific infrastructures that place Europe at the forefront of global research and strategic partnerships.
In partnership with Deutsche Stiftung Weltbevölkerung (DSW), the EU has the tools and the mandate to not only protect public health at home but also shape global health governance. But will it fully seize this opportunity, or will fragmented policies and short-term thinking prevail? The debate is open—what do you think?
