Europe has developed important strategies for cancer, cardiovascular disease, pollution, chemicals and social rights. Yet the causes of preventable disease rarely fit within a single policy area. The Exposome Alliance is therefore proposing a Common Prevention Pillar for the European Union: a framework designed to connect existing initiatives and address the combined environmental, social, commercial and lifestyle factors that influence health across the life course.

Understanding the exposome

The exposome describes the totality of exposures a person experiences from before birth onwards and how those exposures interact with biology over time. Air pollution, chemicals, housing, working conditions, food environments, income, stress, access to green space and commercial practices can accumulate or reinforce one another. The concept helps move prevention beyond isolated risk factors and towards a fuller understanding of why disease develops and why health inequalities persist.

This perspective is especially relevant for non-communicable diseases such as cancer, cardiovascular disease, respiratory illness and diabetes. These conditions share many underlying determinants, while exposure is unequally distributed. People with fewer resources are often more likely to live or work in unhealthy environments and less able to avoid risks. Effective prevention must therefore reduce exposure and inequality at the same time.

Three connected initiatives

The Exposome Alliance brings together researchers, policymakers and civil-society organisations. Its agenda currently focuses on three connected initiatives: a Mission Exposome under Horizon Europe, a European Exposome Data Space and a Common Prevention Pillar. Together, these proposals seek to strengthen research, connect data and translate evidence into coordinated public policy.

The Alliance has proposed a EUR 1 billion research mission and a longitudinal cohort involving 10 million people across Member States. It also calls for a secure and interoperable data space linking health, environmental, social and behavioural information. These are Alliance proposals that will require political discussion, robust governance, data protection and sustainable funding. Their value lies in building the evidence needed to understand how exposures combine and which interventions most effectively protect health.

What a Common Prevention Pillar could do

The proposed Pillar would not replace national responsibility for health policy or create a single new disease programme. Instead, it would provide a shared framework for aligning existing European initiatives and funding instruments. The Alliance points to connections between Europe’s Beating Cancer Plan, the Safe Hearts Plan, the Zero Pollution Action Plan, chemicals policy, food systems, transport, urban development and the European Child Guarantee.

Greater coherence could help decision-makers use common indicators, identify gaps between policy areas and direct resources towards interventions that deliver benefits across several diseases. Measures that improve air quality, healthy housing, safe workplaces, active mobility or access to nutritious food can reduce multiple risks at once. A shared framework could also help Member States develop prevention plans, exchange good practice and evaluate whether policies reduce inequalities rather than only improving averages.

Why this matters to mutuals and health insurers

Solidarity-based health systems see the human and financial consequences of preventable disease over decades. Their members experience the cumulative effects of exposure, while healthcare budgets absorb the costs when prevention is delayed. Mutuals and non-profit payers therefore have a strong interest in policies that act earlier, use evidence well and distribute benefits fairly.

The exposome approach also fits the Health in All Policies principle. Decisions on transport, agriculture, energy, employment and social protection can improve or damage health even when health is not their primary objective. Making these effects visible can support more consistent policy choices and strengthen accountability across sectors. It can also help mutuals share real-world evidence and prevention practices from their members and communities.

A proposal for discussion

AIM is a member of the Exposome Alliance and follows its work with interest. Participation creates an opportunity to contribute the perspective of solidarity-based healthcare payers and to discuss how ambitious concepts could work in practice. AIM will continue exchanging with its members on prevention priorities, governance, financing and the appropriate role of European action.

It is important to be precise about the status of the initiative. The Common Prevention Pillar is an Exposome Alliance proposal discussed in a working session held at the European Parliament. It is not an official position of the European Parliament and it has not been adopted as an AIM policy position. This distinction allows open discussion while respecting each organisation’s decision-making processes. The proposal nevertheless offers a timely starting point for considering how Europe can move from fragmented initiatives towards prevention that reflects the realities of people’s lives.
