Our Story

Tackling climate change could be the greatest global health opportunity of the 21st century.
— The Lancet


The Climate and Health Alliance is Australia’s peak body on climate and health. CAHA is a coalition of 100+ health and medical groups, academic and research institutions, health care service providers and unions.

Since 2010, CAHA has employed effective evidence-based advocacy, a collaborative approach and a willingness to engage professionals, policymakers and media. Today, our Alliance has achieved national and global recognition. The international medical journal The Lancet has described our efforts as an example that leaders should look to “for inspiration and achievement”.

By working together, the health sector can lead action on climate to protect our health.


Why we exist
