Introduction: Understanding Sustainability in Healthcare
Sustainability in the healthcare industry has evolved from a peripheral idea to a strategic imperative. As healthcare systems face rising costs, increasing patient expectations, climate change–related pressures, and social inequities, experts today call for more integrated and forward-looking approaches. As such, the current issue of Healthovation is dedicated to exploring some salient aspects of sustainability in healthcare industry. Traditionally, sustainability referred to conserving resources and meeting present needs without compromising the future. In the healthcare context, this translates into delivering high-quality care while responsibly managing financial, environmental, and social obligations. Frameworks such as the Triple Bottom Line (TBL) focusing on economic, social, and environmental performance have been widely applied to understand sustainability in healthcare settings. More recently, the Environmental, Social, and Governance (ESG) perspective has emerged as a complementary lens, emphasizing ethical operations, equity, and stewardship of resources. Other frameworks, such as the Circular Economy (CE), continuous improvement, and Industry 4.0–enabled innovation, further expand the sustainability discourse by enabling waste minimization, promoting resource efficiency, and improving resilience.
Healthcare organizations across the world are adopting these frameworks to reduce waste, enhance patient and workforce well-being, strengthen financial performance, and reduce the sector’s environmental footprint. It is accepted beyond argument that sustainability in healthcare requires a structured, multi-criteria approach that accounts for lean operations, patient satisfaction, employee well-being, innovation, branding, and corporate social responsibility (CSR).
This editorial synthesises themes from contemporary research to propose a holistic sustainability agenda for healthcare, integrating triple-bottom-line thinking, ESG, circular economy principles, and Industry 4.0 strategies. The final section translates these insights into practical implications for healthcare leaders and managers.
Sustainability Frameworks in Healthcare
1. Triple Bottom Line (TBL) and Its Relevance
The TBL, coined by Elkington (1994), remains one of the most influential frameworks for sustainability in healthcare. It emphasizes that healthcare organizations must pursue:
- Economic sustainability: managing financial resources efficiently and ensuring viability
- Social sustainability: improving community well-being, equity, and workforce health
- Environmental sustainability: reducing carbon emissions, waste, energy use, and ecological impact
In the healthcare sector, TBL provides a systemic understanding of how hospitals, clinics, and health systems operate within (and impacting) the broader social and environmental ecosystems. The post-pandemic context particularly highlights the need for integrated TBL strategies, as systems face simultaneous financial strain, workforce burnout, and climate-related disruptions.
2. ESG and Corporate Responsibility
ESG frameworks complement the TBL by providing measurable indicators across:
- Environmental: waste, emissions, procurement
- Social: equity, patient rights, worker safety
- Governance: transparency, ethical leadership, compliance
Healthcare organizations are increasingly required to report ESG indicators to demonstrate accountability to communities, investors, and regulators. Integrating ESG with TBL helps hospitals expand beyond traditional cost-driven models toward value-based care and social stewardship.
3. Circular Economy in Healthcare
The circular economy seeks to eliminate waste through reuse, recycling, and restorative systems. In healthcare, CE principles include:
- Reprocessing and recycling of medical devices
- Circular procurement (eco-friendly suppliers, low-waste materials)
- Sterilization technologies that extend the life of equipment
- Lean supply chain and inventory management
There is now a consensus among the research and practitioner community that CE is essential to reducing material waste, minimizing environmental damage, and optimizing operational efficiency in healthcare systems.
Industry 4.0 and Innovation for Sustainable Healthcare
