One Health, One Planet: Our Shared Responsibility

Time for action:  A Joint Statement of the EU Cross-agency One Health Task Force and the European and Central Asia Quadripartite on One Health

As wildfires, heat waves, floods, and other interconnected crises intensify in 2025, recognising the link between human, animal, and environmental health – and acting across sectors – is absolutely essential.

This World One Health Day, nine international organisations make four key recommendations and call for action regionally, nationally, and globally to advance the implementation of the One Health approach in Europe.

As representatives of the EU Cross-agency One Health Task Force[i] and the European and Central Asia Quadripartite[ii], we jointly acknowledge the urgency of addressing risks where human, animal, plant and environmental health intersect. These risks, intensified by climate change, pollution, biodiversity loss, land use change, complex food chains and increased trade and travel demand stronger and more integrated prevention and response measures.

The summer of 2025 was the warmest on record[iii]. By early September, nearly one million hectares of land had been lost to wildfires in the EU – far exceeding the long-term annual average of 280,000 hectares[iv]. Marine heatwaves affected nearly the entire Mediterranean, amplifying ecological stress and threatening livelihoods.

Record-breaking heat and extended mosquito seasons have fuelled the spread of West Nile virus, chikungunya, and dengue, while also driving a rise in heat-related illnesses, foodborne infections, and pressure on health systems – especially affecting vulnerable populations. At the same time, animal diseases such as bluetongue, lumpy skin disease and avian influenza threaten animal welfare and food security.

These environmental disruptions further increase the risk of zoonotic- and transboundary diseases, as habitat shifts, unsustainable land use and agricultural practices bring wildlife, livestock, and humans into closer contact.

In light of this, we work closely with the European Commission and call on all stakeholders – governments, other institutions (including financial institutions), civil society, academia, and the private sector – to intensify their commitment to advancing One Health at all levels.

To achieve this, we underscore the urgent need to:

• Enhance global and regional coordination
  Ensure alignment in the implementation of the EU Cross-agency One Health Framework for Action and the Quadripartite One Health Joint Plan of Action, reinforcing global and regional solidarity in tackling transboundary health challenges.

• Invest in stronger One Health governance and collaborative leadership
  As highlighted by the Scientific Advice Mechanism opinion on the One Health governance in the European Union, robust governance is essential to connect policies and actions across sectors. Increased investment is required to strengthen institutional capacities, promote inclusive decision-making and foster collaborative leadership models that can effectively manage complex One Health challenges at regional and European Union levels.
• Make intersectoral collaboration the norm
  Embed One Health into national and subnational governance systems through legislation, sustained financing, and enabling policy frameworks. Build trust and accountability through transparent communication, joint planning and decision-making, data sharing, and cross-sectoral monitoring.
• Leverage evidence to support strategic investment in One Health approaches
  Carry out and build on analyses^v showing the economic and social value of prevention and preparedness through One Health measures. Ensure that policy choices are grounded in scientific evidence and deliver benefits for human, animal, and environmental health, while demonstrating the added value obtained through coordination, collaboration, communication and capacity building that the One Health approach promotes.

As we celebrate World One Health Day, the challenges we face serve as a powerful reminder of our interconnected vulnerabilities and shared responsibilities. To prevent, prepare and respond to the next pandemic, no sector or country can act alone: we must act together, now.

Through dedicated cooperation and proactive measures, the EU Cross-agency One Health Task Force and the European and Central Asia Quadripartite commit to implementing the One Health approach. We invite all partners to join us in this essential endeavour for the health of people, animals, and the planet.

[i] EU One Health Task Force: A joint initiative of five agencies of the European Union that have a technical and scientific mandate in the areas of environmental sustainability, public health and food safety. Members include European Centre for Disease Prevention and Control (ECDC), European Medicines Agency (EMA), European Food Safety Authority (EFSA), European Environment Agency (EEA) and European Chemicals Agency (ECHA) with the contribution of the European Commission/DG SANTE as observer.

[ii] Quadripartite: The Regional One Health Coordination Mechanism for Europe facilitates cooperation between the regional offices of Food and Agriculture Organization of the United Nations (FAO), United Nations Environment Programme (UNEP), World Organisation for Animal Health (WOAH) and World Health Organization (WHO) for the WHO European Region to address risks at the human-animal-ecosystem interface and mainstream the One Health approach.
