Science & Technology (Commonwealth Union) – Databases have always played an essential part in research as it gives the ability to compare and contrast data.
A newly launched database brings together clinicians, engineers, data scientists, economists, and public health experts to advance efforts in decarbonising healthcare systems around the world.
Experts from the University of Birmingham have contributed to developing the first global carbon analytics database, an important tool designed to help hospitals and clinics cut costs, reduce waste, enhance patient care, and address climate change.
The Lancet MedZero platform offers detailed carbon impact data covering a wide range of healthcare activities, including pharmaceuticals, surgical tools, chest X-rays, and blood tests.
Initiated by The Lancet and developed by an international academic consortium led by the National University of Singapore, the database launches with more than 14,000 entries. It represents a worldwide collaboration of clinicians, engineers, data scientists, economists, and public health specialists working together to reduce the environmental footprint of healthcare.
The new platform is designed to support decision-making across all levels of healthcare systems. For instance:
A UK health policymaker could find that replacing incineration with recycling could cut more than 311,000 tonnes of CO₂e—roughly equal to removing 212,000 British cars from the roads—while also saving about £76 million each year.
A hospital chief executive in Singapore might see that switching to reusable surgical gowns could reduce emissions by 4,407 tonnes of CO₂e, comparable to the annual electricity use of 3,159 HDB households, and save approximately 700,000 Singapore dollars annually.
Meanwhile, global procurement specialists could evaluate transport options and discover that choosing lower-carbon freight methods for pharmaceuticals, such as shipping, could reduce emissions by over 3.85 million tonnes of CO₂e—almost twice the total annual emissions of Malta.
The University of Birmingham is now leading a Horizon Europe proposal aimed at expanding the platform’s global reach. The project will focus on stronger evidence governance, integrated assessments of carbon emissions and healthcare resilience, and practical trials in healthcare environments, including NHS England.
The platform was officially introduced during the 79th World Health Assembly, bringing together key global health leaders, including the Editor-in-Chief of The Lancet, the Health Minister of the Philippines, the International Medical Secretary for Doctors Without Borders, the Chief Sustainability Officer of the UK NHS, and the Permanent Secretary of the Thailand Ministry of Public Health.
Dr Richard Horton, Editor-in-Chief of The Lancet, says “The climate crisis is a health crisis. But climate action depends on credible data. The Lancet MedZero plans to create a shared global infrastructure of knowledge about the carbon footprint of health systems. Measurement is the foundation of accountability, and accountability is the motivation for action.”
According to a statement over 100 nations, representing over half of the global population, have pledged to address climate change through the WHO-led Alliance for Transformative Action on Climate and Health. However, healthcare carbon data has traditionally been scattered and difficult to access — a challenge The Lancet MedZero platform was designed to overcome.
To turn those pledges into meaningful action, hospitals and healthcare systems require clear and dependable data to guide evidence-based choices. Whether it is a surgeon improving a treatment pathway, a pharmacist replenishing hospital supplies, a procurement manager revising supplier agreements, or a health minister shaping national policy, each depends on fast and reliable access to product-level carbon information.
The Lancet MedZero combines expertise in healthcare services, carbon measurement, and system-wide transformation, bringing together contributors from Asia-Pacific, Europe, and North America. This international collaboration highlights a common goal of promoting sustainable healthcare solutions across different regions.
Its academic collaborators include Health Intervention and Technology Assessment Program, National Institute for Environmental Studies, National University of Singapore, Northeastern University, and University of Melbourne.
