As the healthcare industry strives for saving lives and promoting well-being, it also significantly adds to environmental footprint. Hospitals and healthcare facilities utilize huge amounts of energy, water, and resources, producing biomedical and other wastes that lead to greenhouse gas emissions, all having negative impact on the environment. This impact has kindled a growing interest in adopting ‘green technologies’ within the healthcare sector.

The purpose of green technology in the modern technological settings is to reduce environmental harm and promote sustainable development.(1) In healthcare, this can include renewable energy sources, such as solar panels, waste reduction strategies, and the use of biodegradable or recyclable materials in medical supplies. For instance, sustainable medical devices, such as reusable or reprocessed instruments are also a part of green technologies as they reduce single-use plastics and procurement costs. Similarly, solar panels on hospital roofs can also help offset electricity usage to further lower long-term costs. (1, 2)

Beyond their environmental advantages, policymakers are often concerned about the cost-effectiveness of such green technologies, which is an essential aspect for healthcare administrators working within tight budgets.(2) Though green technologies often involve higher upfront investments,(3) their long-term financial benefits are substantial.(4) For instance, adapting to energy-efficient systems and renewable energy sources can drastically reduce utility costs.(5, 6) Evidence shows that hospitals transitioning to solar energy can recover their installation costs within 5-10 years through energy savings alone.(7) Similarly, embracing recycling programs and reprocessing single-use devices can facilitate hospitals to reduce both waste volume and disposal costs.(8) For example, implementing on-site composting for organic waste not only reduces waste but also creates reusable resources for landscaping.(8, 9)

Green technologies create healthier indoor environments, improving air quality and reducing harmful chemical exposures. This can enhance patient recovery rates and staff productivity, which can indirectly lead to better financial outcomes through improved efficiency.(10) From a regulatory perspective, governments and environmental agencies worldwide are introducing stricter regulations on carbon emissions and waste management.(11) As a result, healthcare facilities that invest in green technologies can avoid penalties and gain incentives or tax benefits proposed to promote sustainability.

Despite clear advantages, there are several barriers to adopting green technologies. The main hurdle is the high initial cost, which can be a limitation for healthcare facilities with lack of monetary resources. However, innovative financing options like energy performance contracts or green bonds are enabling hospitals to overcome this hurdle. Another challenge is the supposed complexity of implementation, particularly in older buildings. Renovating hospitals with new technologies warrants careful planning and skilled labour, which can defer adoption. To overcome these concerns, educational initiatives and government support can be of help to ensure smoother transitions.(3)

When evaluating the cost-efficiency of green technologies in healthcare, several factors need consideration. These include the initial capital investment needed for execution, such as the installation cost of renewable energy systems or retrofitting available infrastructure. Also, operational and maintenance costs over the lifecycle of a particular product/technology should be assessed, as these can substantially impact long-term savings. Regulatory incentives and penalties also must be taken into consideration, as government policies often incentivize sustainable practices through subsidies or tax benefits while imposing penalties for non-compliance. Furthermore, cost-effectiveness studies should account for indirect benefits, including enhanced patient and staff outcomes from healthier environments and possible public health gains from mitigated emissions. The return on investment (ROI) should integrate these aspects along with environmental metrics, such as reductions in carbon footprint and waste. Lastly, feasibility and implementation challenges, including logistical issues, staff training, and adaptability in older facilities, should be considered to provide an extensive assessment of both costs and benefits.(1, 12, 13)

The benefits of green technologies surpass financial savings. By transitioning to sustainable practices, healthcare organizations can play a vital role in mitigating climate change, yielding direct and indirect health impacts. Extreme weather events, heatwaves, and air pollution excessively affect vulnerable populations, exhausting healthcare systems. Therefore, greener operations will not only save costs but also contribute to achieving the primary goal of enhancing global health. Green technologies are no longer just an ethical preference for healthcare organizations, but a practical, cost-effective solution to operational concerns. By promoting sustainability, healthcare facilities can substantially lower their costs, abide by  regulations, and provide improved care in a healthier environment. Implementing green technologies today ensures resilience and efficacy of healthcare systems resilient, preparing them to meet the challenges of tomorrow.(4, 14)
