Making healthcare sustainable

Greening the healthcare sector through Global Green and Healthy Hospitals (GGHH)

We're supporting hospitals, health services and health organisations in Australia and New Zealand to participate in the Global Green and Healthy Hospital (GGHH) Network.

Global Green and Healthy Hospitals is a free global network for hospitals and health organisations who are committed to reducing their ecological footprint and promoting public and environmental health.

CAHA is proud to have founded and coordinated the Pacific Region of the network since 2012, recruiting 100+ health systems and health networks across Australia and New Zealand to join. 

Other aspects of our Sustainable Healthcare Program

We're also currently running two projects that focuse on reducing plastics in healthcare:
