A new collaborative study between the National University of Singapore (NUS) and the Ministry of Health (MOH) reveals that Singapore’s healthcare system has a carbon footprint 18 percent lower than previous estimates, marking a key milestone in pushing sustainable medicine forward in Southeast Asia.
🔍 What the study uncovered
- The report quantified carbon emissions from the entire healthcare ecosystem—hospitals, logistics, procurement, outpatient care—and found them to be about 4.1 million tonnes of CO₂ equivalent per year. This is lower than anticipated across multiple metrics.
- Singapore’s system is now estimated to operate at a 20 percent lower carbon intensity compared to other advanced health systems, underscoring how environmental responsibility and high care standards can co-exist.
- Key reductions came from sectors such as anaesthesia gas use (where greener alternatives were more broadly adopted) and tighter control over refrigerant emissions—two areas that often drive healthcare carbon output.

Why it matters
- Climate & health linkage: Hospitals and clinics are energy-intensive. Reducing emissions in healthcare is part of broader national goals to hit net zero by 2050 under Singapore’s Green Plan.
- Benchmark for Asia: This is among the first comprehensive national assessments in the region. It positions Singapore as a thought leader in sustainable health, giving other countries a model to follow.
- Targeted interventions: By mapping emissions “hotspots” across the healthcare value chain, policymakers can direct decarbonisation efforts where they yield the most benefit—whether in supply chains, building efficiency, or clinical practices.
