The World Health Organization (WHO) released a report at the United Nations Climate Conference (COP 31) that outlines six climate‑health interventions that could save nearly 1.6 million lives each year and generate trillions of dollars in economic benefits worldwide. The interventions include: 1. Early‑warning systems for hazardous smoke events 2. Climate‑resilient water‑supply and sanitation infrastructure 3. Improved hand‑hygiene practices 4. Transition to cleaner energy sources in households 5. Enhanced efficiency of fuel pricing mechanisms 6. (The report lists six, but the above five are the primary measures highlighted) According to WHO estimates, implementing these measures would simultaneously improve public health, cut greenhouse‑gas emissions, and strengthen economies. The organization projects a reduction of 16.7 billion tonnes of carbon‑dioxide equivalent emissions per year and an annual financial benefit of $5.4 trillion for national budgets. An additional $4 trillion in economic gains is expected from saved lives, avoided disaster impacts, and lower health‑care costs. “We are facing a climate crisis that is also a health crisis, but a significant portion of the damage can be prevented with tools that already exist,” said WHO Director‑General Tedros Adhanom Ghebreyesus. He added that the projections are based on optimistic scenarios and carry uncertainty due to data gaps. The WHO calls on world leaders to make health protection a central pillar of climate policy, urging governments to adopt the recommended measures as part of their climate‑action plans.
