Sustainability In The Healthcare Industry Statistics

Hospitals and health systems generate emissions, hazardous and potentially infectious waste, and plastic pollution, with 9.8% of global CO2 emissions traced to the health-care sector and 78% of healthcare waste in high income countries ending up disposed rather than recycled. This page ties those pressures to practical levers, from 3.0% of global greenhouse gases linked to healthcare supply chains to proven operational fixes that can cut hospital waste by 12% and water use by 20%.

The health sector is responsible for 9.8% of global CO2 emissions, and just how that footprint is created is often misunderstood. Between air pollution impacts linked to millions of deaths, hazardous and potentially infectious waste streams, and climate pressure from supply chains, the statistics reveal tradeoffs hospitals cannot ignore. We break down the most important sustainability figures so you can see where change is most measurable and where it is most urgently needed.
