The Case for Action: The power of prevention to support health in a changing climate

 The Case for Action: The power of prevention to support health in a changing climate, the report was developed with a first-of-its-kind Community of Practice and reveals how practical, city-led interventions can ease pressure on health systems while delivering major health and climate benefits.

The report warns that rising chronic disease, aging populations, skyrocketing healthcare costs and health inequalities are pushing health systems to breaking point. Indeed by 2030, urban mortality from heat is projected to rise 45%, and from air pollution 18% - a combined burden more than double that of transport accidents by 2030.

Yet the report provides hope: low-cost, high-impact measures could transform outcomes. The modelling shows that four bundles of city-led interventions could save more than 725,000 lives per year, cut $70bn in healthcare costs, and avoid 15.6 MtCO₂e (amounting to more than the annual emissions of Prague or Accra), when applied across 11,000 cities globally.
