Sustainability In The Healthcare Industry Statistics 2026

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.
