Core Initiatives

To place prevention at the centre of European health policy, the EU should establish a Mission Exposome under Horizon Europe. With a dedicated €1 billion research budget and a 10-million-person longitudinal cohort across Member States, this initiative would generate the most comprehensive evidence ever produced on how environmental, chemical, biological and social exposures shape health across the life course.

A Mission Exposome would position Europe at the forefront of global research, alongside major international programmes, while strengthening the EU’s competitiveness in health, biotechnology and artificial intelligence. Combined with the Genome of Europe initiative, it would create an integrated knowledge base linking genetic and environmental determinants of health – turning cutting-edge science into actionable prevention.

Effective prevention requires connected data. The Exposome Alliance calls for the creation of a European Exposome Data Space to securely and interoperably link health, environmental, social and behavioural data across the EU.

Building on the European Health Data Space and the EU Life Sciences Strategy, this initiative would make exposomic data visible, usable and actionable. By enabling Member States to connect their infrastructures in a harmonised way, Europe can better understand how real-world exposures interact with biological and genomic factors – improving risk identification, guiding public health interventions and strengthening evidence-based policymaking.

Europe has strong disease-specific strategies, but it lacks a coordinated framework to address the lifelong, combined exposures driving all major non-communicable diseases. A Common Prevention Pillar would strengthen coherence across existing EU initiatives and better support Member States in delivering effective prevention policies.

Using the exposome approach, this pillar would improve coordination between policies on health, environment, chemicals, food systems, urban planning, transport and social inclusion – while respecting national competences. By aligning instruments under the next Multiannual Financial Framework and reinforcing implementation support, the EU can maximise the impact of current strategies and move decisively towards a preventive, cross-sectoral health model.
