One Health & Beyond: A Multi-Stakeholder Declaration.

Launching an Integration Cycle for Future COPs and the next climate engagement cycle

We, the undersigned governments, international organizations, research institutions, civil society organizations and private sector partners,

Recognizing that climate change increasingly affects human, animal and ecosystem health, and that strengthening health resilience enhances climate ambition, social stability and sustainable development,

Recalling the outcomes of recent Conferences of the Parties (COP), including the COP28 Declaration on Climate and Health, the Guiding Principles for Financing Climate and Health Solutions, and the initiatives launched at COP29 and COP30, including the Belém Health Action Plan,

Acknowledging the findings of the Intergovernmental Panel on Climate Change (IPCC) regarding the increasing frequency of climate-sensitive diseases and the necessity of science-based adaptation pathways to reduce systemic vulnerabilities,

Acknowledging that health considerations are already reflected across adaptation, mitigation co-benefits and sustainable development frameworks, and that further integration can be achieved within existing mandates and instruments,

Affirm our shared commitment to advancing the integration of the One Health approach across climate action.

We will progressively strengthen the integration of One Health considerations, as appropriate to national contexts, within Nationally Determined Contributions (NDCs), National Adaptation Plans (NAPs) and relevant national climate, development and sectoral strategies. This includes placing epidemiological surveillance and nutrition at the heart of state adaptation policies to anticipate and respond to evolving sanitary threats.

We encourage the exchange of experiences and good practices in this regard, in preparation for COP31 and subsequent COP sessions.

We commit to fostering science-based action by aligning national health-climate strategies with the latest IPCC assessment reports, ensuring that adaptation efforts are grounded in rigorous climate modeling and epidemiological projections.

We will promote and support the development of implementable initiatives aimed at strengthening the resilience of health systems to climate-related risks, including :

1. continuity of essential health services during climate shocks;
2. climate-informed surveillance and early warning systems;
3. resilient energy and water supply for health facilities;
4. preparedness for climate-sensitive zoonoses, vector-borne diseases and extreme heat

Recognizing the importance of evidence-based policy and anticipatory risk management, we will support voluntary efforts to enhance data collection and knowledge-sharing on climate-related health, zoonotic and vector-borne risks, aiming to reduce uncertainty through better access to climate and health data for all stakeholders. In this context, we emphasize the role of the IPCC in synthesizing global knowledge to help policymakers better understand the complex interactions between climate change and the determinants of health. We will explore the use and refinement of relevant adaptation indicators, including those related to disease surveillance capacity and system resilience, and contribute to learning processes linked to the Global Goal on Adaptation and the Global Stocktake. These efforts will build on existing processes and will not create additional mandatory reporting obligations.

To ensure continuity and coherence across future COPs, we hereby launch a voluntary Health & Climate Integration Cycle for the period 2026–2028).

At COP31 in 2026, signatories will present at a ministerial event concrete progress achieved in integrating climate-related health risks - including vector-borne and zoonotic dimensions as well as the broader impacts of climate change in exacerbating both communicable and non-communicable diseases - into national planning and policy frameworks.

In 2027, a concise multi-stakeholder technical note will be published to consolidate operational lessons, methodological approaches and priority areas for strengthened One Health integration. Ahead of COP32 and the 2028 Global Stocktake, consolidated recommendations will be developed to further strengthen the integration of climate-related health, zoonotic and vector-borne considerations within existing climate architecture and instruments. These recommendations will build on documented national experience and contribute to enhancing coherence across adaptation, resilience and public health planning processes and support the preparation of subsequent Nationally Determined Contributions.

We will work to improve alignment between national priorities and existing financing mechanisms, with a view to facilitating access to climate finance for health-related adaptation and resilience actions, leveraging both public and private investment to build equitable and sustainable health systems.

This voluntary cycle is intended to enhance coherence without altering the mandate of the UNFCCC or creating new institutional structures. It is intended to enhance collaboration and accelerate practical integration of health within climate action, building on existing frameworks and commitments.
