100 Nations Unite to Protect Global Health from Climate Change, Says WHO

The World Health Organization (WHO) announced that 100 countries have now joined the Alliance for Transformative Action on Climate and Health (ATACH). The latest members — Cook Islands, Malaysia, and Tuvalu — bring the total to 100 nations committed to building climate-resilient and low-carbon health systems.

ATACH helps countries share expertise, develop sustainable healthcare, and strengthen systems against climate risks. All members align their efforts with the COP26 Health Agreement, focusing on reducing emissions and improving public health resilience.

WHO said the milestone marks a global effort to protect communities from worsening health threats such as heatwaves, pollution, and vector-borne diseases. The alliance fosters knowledge exchange, technical support, and collaboration to ensure healthcare systems remain strong amid environmental change.

Tuvalu’s membership symbolizes progress for small island nations most vulnerable to rising sea levels and climate impacts. WHO added that global cooperation through ATACH is crucial for achieving a healthier, greener future.
