Launched at the COP30 Belém Climate Summit, the Global Status of Multi-Hazard Early Warning Systems 2025 report provides a snapshot of progress in the implementation of the UN's flagship Early Warnings for All (EW4All) initiative, which aims to protect every person on Earth with an early warning system by 2027. The report reveals measurable progress, with 119 countries, or 60% of all countries, now reporting the existence of a Multi-Hazard Early Warning System. This is a 113% increase over the past 10 years. However, coverage gaps persist, especially among small island developing States, as only 43% of them reported having systems in place.
