Climate change

Climate change is impacting human lives and health in a variety of ways. It threatens the essential ingredients of good health - clean air, safe drinking water, nutritious food supply, and safe shelter - and has the potential to undermine decades of progress in global health.

 

Between 2030 and 2050, climate change is expected to cause approximately 250 000 additional deaths per year, from malnutrition, malaria, diarrhoea and heat stress alone. The direct damage costs to health is estimated to be between USD 2-4 billion per year by 2030.

 

Areas with weak health infrastructure – mostly in developing countries – will be the least able to cope without assistance to prepare and respond. WHO supports countries in building climate-resilient health systems and tracking national progress in protecting health from climate change.

 

Reducing emissions of greenhouse gases through better transport, food and energy-use choices results in improved health, particularly through reduced air pollution. The Paris Agreement on climate change is therefore potentially the strongest health agreement of this century. WHO supports countries in assessing the health gains that would result from the implementation of the existing Nationally Determined Contributions to the Paris Agreement, and the potential for larger gains from more ambitious climate action.

Climate change WHO response

Many policies and individual choices have the potential to reduce greenhouse gas emissions and produce major health co-benefits. The phase out of polluting energy systems, for example, or the promotion of public transportation and active movement, could both reduce carbon emissions and cut the burden of household and ambient air pollution, which cause 7 million premature deaths per year.
