New NUS-MOH study: Singapore’s healthcare sector carbon emissions 18% lower than expected, a milestone in the city-state’s net zero journey

National University of Singapore, Yong Loo Lin School of Medicine
Reports and Proceedings

In a milestone for Southeast Asia’s healthcare sector, Singapore’s Ministry of Health (MOH), 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) have released its first-ever comprehensive national emissions report for Singapore’s healthcare sector, and the first comprehensive study across Asia.

The NUS-MOH study demonstrates that Singapore’s healthcare system is 18%[1] more sustainable than previously estimated, with the country delivering world-class healthcare at 20% lower carbon intensity than other advanced economies.

[1] 18% lower than the most recent estimate of Singapore's healthcare emissions on a 3-year rolling average basis (Romanello et al. (2024).

Indian adolescents are mostly starting their periods at an earlier age than 25 years ago

PLOS
Peer-Reviewed Publication

Indian adolescents are mostly starting their periods at an earlier age than 25 years ago - likely because of demographic factors such as improved education, and possibly even climate change.

Study recommends integrated risk assessment for zoonotic and vector-borne diseases

Fundação de Amparo à Pesquisa do Estado de São Paulo
Peer-Reviewed Publication

A summary of published studies on the risk of emerging diseases shows that only 7.4% simultaneously consider hazard, exposure, and vulnerability to infection. These three components are essential for reliably and accurately assessing the risk of these diseases in the context of environmental change.

‘A canary in the coal mine’: Even fish adapted to dry climates are struggling amid rising temps, droughts

University at Buffalo
Peer-Reviewed Publication

A research team has analyzed four decades of data from nearly 1,500 streams across dry regions of the United States and Australia, and found that the number of fish species there has declined amid rising temperatures and reduced precipitation and streamflow.

Coral reefs set to stop growing as climate warms

University of Exeter
Peer-Reviewed Publication

Most coral reefs will soon stop growing and may begin to erode – and almost all will do so if global warming hits 2°C, according to a new study in the western Atlantic.

Reindeer grazing can mitigate the impacts of winter climate change on forest carbon release

University of Oulu, Finland
Peer-Reviewed Publication

Winter climate change is affecting the carbon exchange of northern coniferous forests, but the response depends upon reindeer grazing, according to a new study from the University of Oulu, Finland. The study compared areas with ongoing reindeer grazing to areas where grazing has been excluded for 25 years at Oulanka and as long as 55 years at Kevo.

A hard look at geoengineering reveals global risks

University of California - Santa Barbara
Peer-Reviewed Publication

With CO2 emissions continuing unabated, an increasing number of policymakers, scientists and environmentalists are considering geoengineering to avert a climate catastrophe. Such interventions could influence everything from rainfall to global food supplies, making the stakes enormous. In brief, manipulating other aspects of Earth’s climate system might reduce some effects of climate change. But the wondrous complexity of our planet complicates every one of these proposals.

Climate change could drastically reduce aquifer recharge in Brazil

Fundação de Amparo à Pesquisa do Estado de São Paulo
Peer-Reviewed Publication

Study shows that most of the country’s underground reservoirs will lose their capacity for renewal, increasing the risk of water shortages in several regions, especially the Southeast and South. One strategy to address the problem is “managed recharge,” which includes techniques that promote the infiltration of rainwater or even treated sewage.

New electrical flash method rapidly purifies red mud into strong ceramics, aluminum feedstock

Rice University
Peer-Reviewed Publication

A team of researchers at Rice University has developed a faster and cleaner method for recovering aluminum and removing toxic metals from bauxite residue, or red mud, which is a hazardous by-product of aluminum production. This new technique, published in American Chemical Society Applied Materials and Interfaces Sept. 15, involves a brief electrical pulse lasting under one minute along with a small amount of chlorine gas. If implemented on a larger scale, it could revolutionize global waste management and materials recovery.
