Green Anaesthesia Calculator

Green Anaesthesia Calculator helps healthcare professionals explore the estimated environmental impact of common anaesthesia practices.

Use the app to calculate estimated carbon emissions for inhalational anaesthesia and total intravenous anaesthesia (TIVA). Select relevant factors—including anaesthetic agent, fresh-gas flow, carrier gas, medication use, equipment, patient weight, and airway device—to view estimated CO₂e per hour and an equivalent driving-distance comparison.

The app also provides educational information about the environmental impact of anaesthetic gases and lower-impact practices where clinically appropriate.

All calculations are performed on your device. No account is required, and the app does not collect patient information.

Important: This app provides educational estimates based on available research data. It is not a substitute for clinical judgement, local protocols, or patient-specific medical advice.
