In brief
- Six WHO measures, if implemented widely, could save 1.6 million lives every year.
- The package could generate about $3.9 trillion in well-being benefits and another $5.4 trillion in annual fiscal returns.
- Widespread implementation could avoid 16.7 billion tons of CO2, equal to 31% of global greenhouse-gas emissions with land use, land-use change and forestry excluded.
- For five of six measures, $1 invested would generate $24 in benefits; €0.80 would generate €21.4.
- The report arrived Wednesday before COP31, which was scheduled to open Monday in Turkey.
The World Health Organization estimates that widespread use of six climate-and-health measures could save 1.6 million lives every year and generate about $3.9 trillion, or roughly €3.5 trillion, in annual well-being benefits.
The report, “Benefits and Global Costs of Priority Action on Climate Change and Health,” was released on the Wednesday before the 31st United Nations Conference on Climate Change, or COP31, was due to open Monday in Turkey.
What are the six measures?
WHO assessed six interventions:
- Early-warning systems for health risks linked to heatwaves.
- Drinking-water infrastructure adapted to climate change.
- Basic sanitation services.
- Hygiene and handwashing facilities.
- Cleaner fuels and household technologies for cooking and heating.
- More efficient frameworks for pricing fossil fuels—policies for setting those prices.
Together, these measures connect immediate health protection with energy use and pollution. Early warnings, climate-adapted water infrastructure, sanitation and hygiene can reduce health risks; cleaner home technologies and fossil-fuel pricing also influence emissions. That lets WHO assess more than illness, including spending, productivity and environmental losses.
WHO calls the result a “triple dividend”: healthier populations, fewer polluting emissions and stronger economies.
Takeaway: The package protects health while changing how homes and governments handle energy and resources.
Why would the measures save lives and money?
“Climate change is clearly one of the defined health threats of the 20th century,” Frank Pega, a technical expert in climate health economics at WHO’s Department of Climate Change, Air Quality, Energy and Health, said. “To avoid preventable deaths, to prevent illnesses and to make sure that we do not have these economic losses, countries must accelerate climate action now.”
The report counts four sources of well-being benefit:
- The monetary value of lives saved.
- Reduced health spending.
- Increased productivity.
- Prevention of climate and environmental losses.
Together, those channels turn health protection into a broader economic estimate. Fewer deaths carry monetary value, while less illness can reduce medical costs and support productivity. Avoiding climate and environmental losses adds another stream of benefit.
The report’s $3.9 trillion estimate combines those four channels. WHO also projects another $5.4 trillion, or €4.8 trillion, in annual fiscal returns, meaning money returning to public budgets.
Takeaway: Health savings are only the start; WHO expects lower pollution and stronger public finances too.
How large are the emissions and economic gains?
Widespread implementation could also avoid about 16.7 billion tons of carbon dioxide, equivalent to 31% of global greenhouse-gas emissions. The comparison excludes land use, land-use change and forestry.
For five of the six measures, every $1 invested would generate $24 in benefits. In euro terms, €0.80 would generate €21.4 in benefits. That ratio covers five measures, not all six.
These are modeled potential gains, not outcomes already recorded. The condition is widespread implementation. WHO says the impact would be especially large in low- and middle-income countries, helping reduce health and economic inequalities.
Takeaway: The gains could be enormous, but they depend on broad implementation rather than isolated projects.
What must COP31 deliver?
Diarmid Campbell-Lendrum, head of WHO’s Unit on Climate Change, Air Quality, Energy and Health, urged governments at COP31 to negotiate “as if people’s lives depended on it, because they do,” and reach ambitious agreements.
He cited recent climate extremes: many countries had experienced the hottest year in their history; Europe’s record temperature had caused tens of thousands of deaths; a flash flood in Nepal had caused serious consequences; and El Niño would bring further impacts.
Campbell-Lendrum also said there had been too little progress across the previous 30 COPs. “Sometimes we hear that this is because there is too much uncertainty around the impacts or that the actions we need to take will cost too much,” he said.
He answered with the report’s central message: “Today, the WHO is launching a report that shows that this is not the case. It is not an excuse not to take action.”
Takeaway: COP31 must turn WHO’s estimates into commitments that can prevent illness, deaths and economic losses.
