In a groundbreaking advancement for sustainable healthcare in Southeast Asia, Singapore’s Ministry of Health (MOH), together with MOH Holdings Pte Ltd (MOHH) and the Centre for Sustainable Medicine (CoSM) at the Yong Loo Lin School of Medicine, National University of Singapore (NUS Medicine), has unveiled its first-ever comprehensive emissions inventory for the country’s healthcare sector. This pioneering report is the first of its kind across Asia, setting a precedent in environmental responsibility aligned with modern healthcare services. By meticulously mapping the carbon footprint of its entire healthcare infrastructure from April 2023 to March 2024, Singapore establishes itself as a global leader on the forefront of sustainable medicine.
Singapore’s healthcare system has demonstrated an impressive environmental performance, delivering medical services at a carbon intensity approximately 20% lower than comparable advanced economies. This revelation, as revealed by the NUS-MOH collaboration, marks an 18% improvement over prior estimates of the sector’s greenhouse gas emissions. Such data challenges conventional assumptions about the carbon cost associated with high-caliber healthcare, reflecting Singapore’s commitment to integrating sustainability into healthcare delivery without compromising quality or accessibility.
The milestone report emerged from a year-long comprehensive study, incorporating data from all public healthcare clusters, including National University Health System (NUHS), National Healthcare Group (NHG), Singapore Health Services (SingHealth), and the Agency for Logistics and Procurement Services (ALPS). Under the strategic guidance of CoSM, this study amalgamates emissions from an array of healthcare activities—ranging from energy consumption in hospital facilities to procurement logistics and clinical practices—accounting for a total of 4.1 million tonnes of carbon dioxide equivalent (Mt CO₂e) annually. This quantum equates roughly to the energy consumption of all 1.4 million Singaporean households, highlighting the significance of the healthcare system’s environmental impact.
The detailed carbon inventory highlights six principal emissions hotspots that shape the sector’s overall footprint. Medicines and medical products alone account for nearly a third of emissions, primarily from pharmaceutical manufacturing, transportation, and use of medical devices such as thermometers, sterilization equipment, and personal protective gear. Singapore has made notable strides to reduce emissions in this category, exemplified by substantial reductions in potent anesthetic gases like desflurane and nitrous oxide—some hospitals have effectively phased out these gases entirely, replacing traditional systems with advanced, leak-minimizing canisters.
Building construction and maintenance represent the next largest category of emissions, contributing 19% to the sector’s footprint. This includes both the embodied carbon from materials and the operational emissions of maintaining medical equipment and infrastructure. Singapore’s approach here integrates sustainability from the ground up, mandating low-carbon materials and embedding lifecycle carbon assessments in planning protocols. Recent initiatives such as the Woodlands Health Campus expansion exemplify innovation in green healthcare infrastructure, ensuring that new hospital developments minimize emissions not only during construction but throughout their operational life.
Non-medical products and capital expenditure, encompassing laboratory instruments, cleaning services, and catering operations, contribute 17% of emissions. Efforts to curb these involve a strategic pivot toward local procurement, embracing Singapore-based suppliers with low-carbon supply chains, and embedding emissions criteria within procurement policies. Such frameworks benefit from Singapore’s highly integrated national procurement systems, enabling cross-sector collaboration and accelerating the transition to sustainable purchasing without sacrificing quality or reliability.
The operational emissions from hospitals and polyclinics—accounting for 14%—largely stem from electricity used for lighting, air conditioning, powering medical devices, and waste treatment. Notably, Singapore’s public hospital buildings adhere to stringent energy efficiency standards, including Green Mark certification, ensuring that energy consumption is optimized. Current retrofitting initiatives and upgrades are expected to further reduce these emissions as older buildings conform to modern sustainability benchmarks.
Information technology, an often-overlooked component, constitutes 13% of the healthcare sector’s emissions. The robust digital health infrastructure in Singapore relies on data centers, server farms, and communication networks, all of which are energy intensive. Embracing cutting-edge cooling technologies, optimizing server loads, and adopting energy-efficient hardware form the backbone of ongoing efforts to decarbonize the IT ecosystem supporting healthcare services.
Transportation emissions, while comprising a modest 5% of the total, cover a wide spectrum including staff commuting, patient travel, ambulance fleets, and supply logistics. Singapore’s compact urban environment and world-class public transit systems mitigate transport-related carbon emissions effectively compared to other nations. Future strategies envisage further reducing emissions through fleet electrification and incentivizing sustainable commuting among healthcare workers.
Singapore’s progress is not merely theoretical; it is grounded in concrete institutional achievements across multiple healthcare entities. The National University Hospital (NUH) has pioneered a nurse-led recycling program that increased plastic waste recycling rates by 230%, showcasing how frontline staff can drive environmental change. Changi General Hospital (CGH) has achieved a staggering 90% reduction in anesthetic gas emissions through clinical innovations, shifting to eco-friendlier anesthetics that are both cost-effective and sustainable.
A systemic, integrated approach to sustainability has catalyzed initiatives like Tan Tock Seng Hospital’s medication packaging recycling program, actively engaging patients, caregivers, and local businesses alike. This exemplifies a community-wide paradigm shift in healthcare sustainability: embedding environmental consciousness into everyday healthcare interactions and administration.
Leadership in this domain transcends local practice. Singapore boasts the world’s first Master of Science degree in Sustainable Healthcare, offered by NUS Medicine, equipping future medical professionals with essential expertise in sustainable practices. National University Hospital has further cemented its global reputation by becoming the first hospital to secure the Joint Commission International Healthcare Sustainability Certification, a testament to Singapore’s commitment to environmental performance and clinical excellence hand in hand.
This comprehensive emissions report, launched during the inaugural Western Pacific Action Forum on Climate-Resilient and Sustainable Health Systems, reaffirms Singapore’s national pledge under the Singapore Green Plan 2030 to achieve net-zero emissions by 2050. The data-driven insights empower healthcare leaders to identify priority areas for intervention, safeguard patient care quality, and shape policy with precision. Singapore’s model exhibits replicable strategies for sustainable healthcare transformation worldwide.
World Health Organization (WHO) officials have lauded Singapore’s leadership, especially relevant given the escalating health demands and mounting climate risks across the Western Pacific. WHO emphasizes that sustainable healthcare is imperative—not optional—to ensure global resilience, effective resource allocation, and improved health outcomes in a rapidly changing climate context.
Singapore’s healthcare emissions report exemplifies the intersection where cutting-edge medicine meets environmental stewardship. It charts a roadmap of innovation, cooperation, and accountability that other nations can emulate as the world faces an urgent climate-health nexus. By building sustainable frameworks today, Singapore is ensuring that future generations inherit a health system that not only saves lives but also protects the planet.
