About the Climate Atlas
Understanding the urgent need for climate action in healthcare and how this Atlas supports the transformation toward sustainable, resilient health systems.
The global health sector is increasingly vulnerable to climate change, while simultaneously contributing significantly to greenhouse gas (GHG) emissions. Healthcare systems worldwide are responsible for an estimated 5-8% of global greenhouse gas emissions, making urgent action essential.
Despite the sector's significant contribution to global emissions, many high-impact mitigation and adaptation measures remain underused, largely due to barriers such as limited time, resources, and access to tailored information. This Atlas addresses these challenges by making evidence-based solutions accessible to those who need them most.
A world where healthcare systems are resilient, sustainable, and low-carbon, ensuring quality care while safeguarding planetary and human health for future generations.
To curate, organize, and disseminate knowledge on peer-reviewed innovative solutions that drive the transformation of healthcare systems toward sustainability, resilience, and carbon neutrality. Our repository serves as a global resource for healthcare professionals, leaders, policymakers, and institutions striving for climate-smart, high-quality care.

This Atlas builds upon the foundational work of the Low-Hanging PEACH Tree, developed by Dr. Myles Sergeant and colleagues at the Partnerships for Environmental Action by Communities within Health Care Systems (PEACH) at McMaster University in Hamilton, Ontario.
Solutions are categorized by their emissions reduction potential using the PEACH framework.
