Healthcare is one of the most resource-intensive sectors, with hospitals requiring large amounts of energy, medical supplies, and equipment to deliver safe and effective care. As global pressures to reduce carbon emissions and improve efficiency grow, healthcare organisations are looking to adopt sustainable strategies that preserve resources without compromising the quality of service. Artificial Intelligence (AI) is emerging as a powerful tool in this effort.
This training scenario explores how AI-driven technologies can improve the sustainability of healthcare operations, with a focus on supply chain optimisation, energy management, and clinical efficiency. By following the example of a large teaching hospital, you will see how AI can reduce waste, lower emissions, and improve decision-making across the system.
At the end of this scenario, you will complete a Knowledge Check Quiz designed to reinforce your understanding of sustainable AI applications in healthcare.
Scenario: Green Initiatives at St. Anne’s Hospital
AI in the hospital supply chain
St. Anne’s Hospital, like many large healthcare centres, relied on complex supply chains to manage pharmaceuticals, consumables, and imaging equipment. Stock mismanagement often led to wasted medications, unnecessary storage costs, and expired materials being discarded.
The hospital introduced AI-driven supply chain optimisation, which analysed historical usage patterns, patient admission forecasts, and delivery schedules. This system reduced unnecessary stockpiling, minimised expired inventory, and cut down on emergency re-orders. The result was lower operational costs and a measurable reduction in waste and carbon emissions.
Managing energy use in hospitals
Hospitals are among the most energy-intensive buildings due to the constant operation of imaging systems, ventilation, and climate control. To address this, St. Anne’s integrated AI-based energy management systems.
AI monitored heating, ventilation, and lighting in real time, adjusting systems based on patient load and time of day. In diagnostic imaging, AI-assisted scheduling ensured that scanners such as MRI and CT were not left idling for long periods. These measures reduced energy consumption, supporting the hospital’s sustainability targets.
Circular economy in medical equipment
Another initiative addressed the environmental impact of discarded medical devices. The hospital explored a circular economy approach, where equipment was refurbished, reused, or recycled instead of being discarded. AI played a role by predicting device lifespan through predictive maintenance, ensuring equipment was repaired before failure. This reduced e-waste and extended the usability of costly imaging systems.
E-waste concerns in AI-driven healthcare
The Chief Sustainability Officer explained that although AI tools improve efficiency, they also contribute to electronic waste (e-waste) through high-powered servers, sensors, and computing devices. Improper disposal of these materials poses environmental hazards due to toxic components. To address this, St. Anne’s adopted policies for responsible recycling of outdated IT infrastructure and partnered with certified e-waste processors.
Data management and computational load
Medical imaging generates enormous datasets, consuming large amounts of storage and energy for processing. AI-supported sustainability by applying energy-saving methods such as model compression and federated learning, which reduce the computational load without sacrificing accuracy. These approaches enabled the hospital to manage data more efficiently and cut energy use in its IT systems.
Clinical efficiency and diagnostic imaging
AI also improved the sustainability of diagnostic imaging workflows. By helping radiologists detect disease earlier and with greater precision, AI reduced the need for repeat scans. Automated triage algorithms optimised scheduling, ensuring imaging machines operated at maximum efficiency. These improvements saved energy, reduced patient exposure to radiation, and lowered overall costs.
Telemedicine and sustainable practice
During the COVID-19 pandemic, St. Anne’s expanded its telemedicine services. AI-powered platforms supported remote consultations, reducing the need for patient travel and lowering hospital footfall. Beyond improving access to care, telemedicine significantly decreased the hospital’s carbon footprint by cutting transport-related emissions.
Cross-border collaboration for sustainable AI
The hospital recognised that sustainability challenges extend beyond national borders. St. Anne’s joined an international consortium where hospitals shared data and AI models for sustainability applications. This cross-border collaboration helped pool resources, harmonise standards, and accelerate the development of low-energy AI tools.
Policy actions and sustainability goals
Finally, St. Anne’s adopted institutional policies aligned with sustainable AI in healthcare. These included requiring procurement contracts to consider environmental impact, supporting renewable energy integration, and mandating regular audits of AI-driven operations. Such policy actions ensured sustainability was not a one-time project but a continuing organisational commitment.
Key Concepts Illustrated
Through St. Anne’s experience, several sustainability principles were highlighted:
- AI-driven supply chain optimisation reduces waste, costs, and carbon emissions.
- AI energy management helps hospitals monitor and adjust energy use in real time.
- Circular economy principles encourage the reuse, repair, and recycling of equipment.
- E-waste is a growing concern in AI-driven healthcare and must be managed responsibly.
- Computational efficiency methods like model compression lower energy demand.
- AI in diagnostic imaging reduces repeat scans and improves efficiency.
- Telemedicine reduces travel-related emissions and improves access to care.
- Cross-border collaboration accelerates sustainable AI development.
- Policy actions institutionalise sustainability goals in healthcare organisations.
Conclusion
The St. Anne’s Hospital scenario demonstrates how AI can actively support healthcare sustainability through better resource management, improved efficiency, and long-term planning. While challenges such as energy demand and e-waste remain, strategic adoption of AI technologies offers significant opportunities to reduce healthcare’s environmental footprint.
By aligning supply chains, imaging workflows, energy use, and policy with AI-driven insights, hospitals can deliver high-quality care while protecting future resources.
