Hospitals are making progress on sustainability, but energy and resource use remain stubbornly high. Global hospitals account for 3 to 8% of national energy consumption, and HVAC systems drive 54% of hospital energy demand. Waste diversion in US hospitals averaged 25% in 2021, while water use runs around 300 gallons per bed per day.
Key Takeaways
- In 2021, US hospitals achieved 25% waste diversion rate on average.
- Healthcare buildings consume 2.5 times more energy per sq ft than commercial average.
- UK NHS energy use: 31 TWh/year, 4% of public sector total.
- Healthcare contributes 4.4% of US GHG emissions, higher than all transportation except roads.
- UK NHS emits 25 million tonnes CO2e/year, 5.4% national total.
- Global healthcare GHG: 4.4% worldwide, projected 10 GtCO2e by 2050 without action.
- Healthcare supply chain responsible for 60-80% total emissions.
- US hospitals spend $150 billion/year on supply chain, 30% emissions driver.
- UK NHS procurement: £8 billion sustainable spend target by 2023.
- In the United States, the healthcare sector generated approximately 5.24 million tons of regulated medical waste in 2020, representing about 2% of total municipal solid waste.
- UK hospitals produce an average of 3 kg of waste per inpatient bed per day, with 85% being non-hazardous and potentially recyclable.
- Globally, healthcare facilities discard over 50,000 tons of single-use plastic annually from IV bags and tubing alone.
- In 2022, global healthcare water use reached 1.2 trillion liters annually.
- US hospitals consume 300 gallons per bed per day on average.
- UK NHS water usage: 700 million m³/year across facilities.
Hospitals globally consume far more energy, emit more greenhouse gases, and generate huge waste, yet efficiency can cut both fast.
