Greening healthcare

Can we save lives and save the planet? Hear how the healthcare sector is changing to be more sustainable.

This event was held at the University of Sydney on 22 August 2023.

Healthcare is both affected by, and contributes to, climate change. If the global health sector were a country, it would be the fifth largest emitter of greenhouse gases in the world.

How can Australia work towards a more sustainable healthcare system without compromising on quality and safety?

With growing recognition of the close-knit ties between health and climate action, there is hope and energy driving new sustainable collaborations and innovations. Play back this event by Sydney Ideas and the Sydney Environment Institute to hear about exciting developments in this space.

  • Sustainability researcher Dr Amanda Irwin, from the Integrated Sustainability Analysis team, explains the impact of health on the environment and how this compares with other sectors and industries at a national and global level.
  • Cardiology Professor David Celemajer provides a clinical perspective on how practitioners and patients engage with treatment choices and green options.
