Importance of sustainability in healthcare
The healthcare sector is critical in improving public health and saving lives, but its operations also have significant environmental impacts, such as:Â
Greenhouse gas emissions
The healthcare sector is a major contributor to global greenhouse gas emissions. Research finds the healthcare industry is responsible for around 5 percent of global greenhouse gas emissions. These emissions arise from various sources, including:
- Energy use: Hospitals and healthcare facilities are energy-intensive, relying on electricity, heating, and cooling systems that often use fossil fuels.
- Medical supply chains: The production, transportation, and disposal of medical supplies and equipment contribute to indirect emissions.
- Patient travel: Emissions from patient and staff transportation add to the sector’s carbon footprint.
Resource consumption
The healthcare sector uses vast amounts of resources, including water, energy, and raw materials. Key areas of resource consumption include:
- Energy: Hospitals operate 24/7, requiring continuous energy for lighting, medical equipment, HVAC systems, and sterilisation processes.
- Water: Healthcare facilities consume significant quantities of water for sanitation, sterilisation, and patient care.
- Materials: Single-use medical devices, plastics, and pharmaceuticals require raw materials, leading to resource depletion.
Waste generation
Healthcare generates substantial amounts of waste, much of which is hazardous or difficult to manage. Types of waste include:
- Medical waste: Items like syringes, gloves, and contaminated materials are classified as infectious or biohazardous and require specialised disposal.
- Pharmaceutical waste: Expired or unused medications can contaminate water systems if not disposed of properly.
- Plastic waste: Single-use plastics, widely used in packaging and medical supplies, contribute significantly to landfill and ocean pollution.
Air and water pollution
- Air pollution: The use of fossil fuels for energy generation releases pollutants such as carbon dioxide, nitrogen oxides, and particulate matter into the atmosphere.
- Water pollution: Improper disposal of pharmaceuticals and chemicals can contaminate water supplies, harming aquatic ecosystems and human health.
- Incineration: The burning of medical waste can release toxic pollutants, including dioxins and mercury, into the environment.
Supply chain impacts
The healthcare supply chain has a broad environmental footprint, from the production of pharmaceuticals to the transportation of medical supplies. Key issues include:
- Pharmaceutical manufacturing: Producing medicines is energy-intensive and often involves hazardous chemicals.
- Transportation: The global supply chain involves significant emissions from the transport of equipment, medicines, and supplies.
Deforestation and land use
The demand for raw materials in medical equipment and pharmaceutical production can lead to deforestation and land use changes. This further contributes to environmental degradation and biodiversity loss.
Key strategies for sustainability in healthcareÂ
The healthcare sector needs to adopt sustainable practices to reduce its environmental footprint while maintaining high-quality care. A multifaceted approach addressing energy use, waste management, procurement, and infrastructure is essential. Below are key sustainability strategies in healthcare.Â
Transition to renewable energy
Healthcare facilities are energy-intensive, making the shift to renewable energy sources critical. Solar and wind power installations can significantly reduce reliance on fossil fuels, while upgrading HVAC systems, lighting, and medical equipment to energy-efficient models further lowers energy consumption. Smart energy management systems can also optimise energy use, minimising waste and improving efficiency.
Improve waste management
The healthcare sector generates vast amounts of waste, much of it hazardous. Effective waste management begins with proper segregation to ensure safe disposal and maximise recycling opportunities. Another impactful step is reducing single-use plastics by transitioning to reusable or biodegradable alternatives. Circular economy practices, such as reusing and repurposing materials, can further drive sustainability in healthcare.Â
Sustainable procurement
Leveraging purchasing power to promote sustainability is a key strategy. Healthcare organisations can partner with environmentally friendly suppliers who prioritise sustainable practices. For example, suppliers using renewable materials or reducing emissions. Incorporating green criteria into procurement policies ensures that products with lower carbon footprints are prioritised. Local sourcing also helps reduce transportation emissions, contributing to a more sustainable supply chain.
Optimise water use
Water is a critical resource in healthcare, and optimising its use is essential. Installing water-saving technologies, such as low-flow faucets and efficient sterilisation systems, can significantly reduce water consumption. Detecting and fixing leaks promptly minimises waste, while recycling and reusing treated water for non-potable applications, such as landscaping or cooling, adds further value.
Design and build green facilities
Sustainable building practices can greatly reduce the environmental impact of healthcare infrastructure. Energy-efficient materials, insulation, and renewable energy systems are integral to green facility design. Achieving certifications like the Leadership in Energy and Environmental Design (LEED) or Building Research Establishment Environmental Assessment Method (BREEAM) ensures adherence to sustainability standards. Similarly, incorporating green spaces into facility designs can enhance air quality and improve patient well-being.
Promote sustainable transportation
Reducing emissions associated with transportation is crucial for sustainability. Telemedicine and virtual consultations can limit the need for patient travel. Another effective measure is encouraging public transportation through subsidies or facility improvements for staff and patients. Transitioning ambulance and logistics fleets to electric vehicles (EVs) is another way to accelerate environmental sustainability in healthcare.Â
Engage in sustainable practices across the supply chain
The healthcare supply chain is a significant contributor to the sector’s environmental footprint. Collaborating with suppliers to reduce emissions, improve packaging sustainability, and optimise logistics can make a substantial difference. Conducting lifecycle assessments of products also helps evaluate environmental impacts and informs better procurement decisions.
Incorporate education and culture change
Building awareness and embedding sustainability into organisational culture is vital for long-term success. Training staff on sustainable practices and their role in reducing environmental impact ensures widespread participation. Leadership commitment to sustainability reinforces its importance, while community engagement raises awareness about sustainability in healthcare.Â
Invest in digital solutions
Digital technologies offer a way to streamline healthcare operations while reducing environmental impacts. Transitioning to electronic health records (EHRs) minimises paper use, while telehealth and virtual consultations reduce resource consumption and patient travel. Advanced technologies such as artificial intelligence (AI) and data analytics can optimise resource allocation and energy use, enhancing efficiency.
Monitor and report sustainability progress
Measuring and communicating sustainability efforts is crucial for accountability and improvement. Conducting regular carbon audits helps identify areas for emissions reduction, while sustainability reporting provides transparency and showcases achievements. Benchmarking performance against industry standards also drives continuous improvement.Â
