Climate change

    Overview

    The global climate is changing. This affects human health, well-being and life on earth. In the near future it will lead to an amplification of current health problems, as well as new risks and pressures for the environment and the social and economic determinants of health.

    Impact
    In the WHO European Region, health effects have already been observed from more frequent and intense extreme weather events as well as changes in the the geographic range of some infectious disease vectors.
    WHO response
    WHO/Europe works to identify policy options to help prevent, prepare for and respond to the health effects of climate change, and supports its Member States in selecting and implementing the most suitable policies, measures and strategies.

    Overview

    WHO/Europe works to identify policy options to help prevent, prepare for and respond to the health effects of climate change.

    Our activities include:

    • assessing climate health risks;
    • advising Member States in the development and implementation of evidence-based policies and measures that integrate health in national mitigation policies and adaptation strategies;
    • promoting policies and measures in all sectors that benefit both human health and the climate system;
    • identifying the health gains and other co-benefits resulting from mitigation and adaptation measures;
    • addressing building climate-resilient health systems, and supporting strengthening of health surveillance, early warning and preparedness;
    • developing evidence-based guidance on effective interventions in addressing extreme weather events associated with climate change, including for the development of heat health action plans and flood preparedness and response plans for the health sector;
    • providing technical support ahead of and during emergencies induced by extreme weather events (i.e. heat, cold and floods).

    WHO/Europe’s work on climate change and health is in alignment with and supports implementation of a range of global and regional policy commitments, including the 2008 World Health Assembly resolution 61.19 on climate change and health; the 2019 WHO Global Strategy on Health, Environment and Climate Change; the 2017 Declaration of the Sixth Ministerial Conference on Environment and Health; and the European Programme of Work 2020–2025 – “United Action for Better Health in Europe”, which sets out a vision of how WHO/Europe can support countries’ health authorities towards meeting citizens’ expectations to be able to secure better health and well-being.

    WHO/Europe provides secretariat functions to the Working Group on Health in Climate Change (HIC), established under the European Environment and Health Task Force. HIC supports countries of the WHO European Region with implementation of their commitments towards protecting health from the adverse effects of climate change and facilitates dialogue and cooperation among countries and stakeholders.
