WHO Report Outlines Six Climate Actions to Prevent 1.6 Million Annual Deaths

The World Health Organization (WHO) published a report on Wednesday outlining six target interventions in health and climate policy that could prevent 1.6 million premature deaths globally each year. According to the UN agency, implementing these measures would avert approximately one out of every 40 deaths worldwide while generating trillions of dollars in economic returns.

WHO Director-General Tedros Adhanom Ghebreyesus stated that "the climate crisis is a health crisis, but much of the harm it causes can be prevented with tools we already have." He added that protecting health must take priority as governments prepare for upcoming international climate negotiations. The report focuses on measures designed to address air pollution, extreme heat waves, infectious diseases, and contaminated water supplies.

The recommended measures include heat-health warning systems to alert communities during extreme temperature spikes, alongside climate-resilient drinking-water infrastructure and expanded basic sanitation facilities. The health agency also calls for transitioning households to cleaner cooking and heating fuels to reduce indoor air pollution. Additionally, the proposal emphasizes stronger national policies on fossil fuel pricing to ensure market costs reflect environmental and public health impacts.

According to the report, reforming fossil fuel pricing and reducing reliance on fossil fuels would deliver the single largest health benefit, preventing more than one million deaths annually from non-communicable diseases and traffic accidents. The WHO estimates that this measure alone would yield 5.4 trillion US dollars in fiscal benefits each year. For the remaining five interventions, the agency calculates an average economic return of 24.80 US dollars for every dollar invested, with the highest relative gains projected for low- and middle-income nations.

The findings come as an estimated 3.6 billion people currently live in regions highly vulnerable to climate-related health risks. The WHO projects that without additional interventions, specific climate threats such as heat stress, malaria, diarrhoea, and undernutrition will cause 250,000 additional deaths annually between 2030 and 2050. The agency also projects that changing weather patterns could expose an additional 500 million people to disease vectors by 2050.
