Tuvalu has officially become the 100th nation to join the Alliance for Transformative Action on Climate and Health (ATACH). This milestone comes as the Cook Islands, Malaysia, and Tuvalu all joined the initiative, bringing together 100 countries and regions dedicated to advancing climate-related health action.

With a growing commitment among UN Member States to address climate and health challenges, the Alliance serves as a platform to support global health through environmentally responsible and climate-resilient strategies. ATACH is a voluntary network that allows its members—countries, territories, and collaborators—to exchange information, strategies, and tools to build low-carbon, sustainable health systems tailored to national needs.

The Cook Islands, Malaysia, and Tuvalu joined the alliance between July and October 2025. By joining ATACH, these members pledge to strengthen their health sectors to better withstand climate effects and to align with the COP26 Health Commitments, promoting cleaner and more resilient healthcare infrastructures.

Each of these three countries faces unique climate-related health and economic threats. Malaysia, with its fast-developing economy and rich natural assets, is taking proactive steps toward sustainability and resilience in healthcare. The Cook Islands and Tuvalu, both categorized as small island developing states, are among the most affected by climate change. Tuvalu, the World Health Organization’s smallest member state, has consistently advocated for climate-health solutions over the years. All ATACH members benefit from the collective insights, experience, and tools shared within the network.

The World Health Organization extends a warm welcome to the Cook Islands, Malaysia, and Tuvalu, now part of a global alliance of 100 countries and more than 95 partners. WHO urges other nations to consider joining ATACH to accelerate progress in safeguarding healthcare and public health from climate challenges through national and local efforts. This global movement is focused on achieving practical change by equipping countries with the support needed to adapt and create health systems that are both climate-aware and sustainable for future generations.

About ATACH

Formed in 2022, ATACH was created to support the implementation of the COP26 Health Commitments focused on climate-resilient and low-carbon health systems. Since its inception, the alliance has rapidly expanded to include 100 countries, over 95 non-state partner organizations, and a wide range of stakeholders working collectively to put these commitments into practice. Members use the platform to share valuable insights, case studies, and resources, contributing to a global exchange of knowledge aimed at reinforcing healthcare systems against the impacts of climate change.
