One Health is an integrated, unifying approach that seeks to sustainably balance and optimise the health of people, animals and ecosystems. Building climate-resilient and low-carbon health systems provides a practical and scalable entry point for supporting a One Health approach in the context of climate change. Climate-informed surveillance and early warning systems strengthen detection of climate-sensitive diseases and zoonoses; resilient infrastructure and service delivery safeguard continuity of essential health services during climate shocks; integrated information systems support AMR surveillance and response; and a climate-prepared health workforce enhances the health sector’s ability to engage in coordinated prevention and response across sectors.
This event, co-hosted by WHO, the French Ministry of Health and Unitaid as part of the ongoing work of the G7 Health, will convene policymakers, practitioners, researchers and partners from health, environment, agriculture and climate sectors to examine how climate-resilient health systems are a critical One Health solution. Drawing on country experience and initiatives such as the Alliance for Transformative Action on Climate and Health (ATACH) and the Bélem Health Action Plan, the discussion will focus on climate-resilient and low-carbon health systems, financing and accelerating action across sectors, supportive of a One Health approach.
This event is part of the One Health Festival accompanying the One Health Summit in Lyon, France on 7 April 2026, showcasing global initiatives linking human, animal, and ecosystem health.
It will serve also as preparatory meeting for the High-level strategic ATACH meeting to be organised in collaboration with the French Ministry of Health on 25 June 2026 in Paris, France.
