Healthcare systems around the world are increasingly recognized as significant contributors to climate change, accounting for an estimated 4 to 5% of global greenhouse gas emissions. In France, this figure rises to nearly 8% of the national carbon footprint, as estimated by the think tank The Shift Project. Within this context, hospitals-particularly university hospitals-play a pivotal role in shaping a more sustainable future for healthcare.
French university hospitals (CHUs) are unique in their triple mission of care, teaching, and research. They also act as major economic and social anchors in their territories, often being the largest employers and regional stakeholders. Their transformation into "green hospitals" is therefore not only necessary but strategic. This ecological transition reflects a broader awareness that the environmental impact of hospitals extends far beyond carbon emissions, encompassing biodiversity, natural resource consumption, pollution, and waste management.
While many hospitals have initiated actions in response to climate and environmental challenges, efforts have often lacked coordination or long-term structure. Today, a more systemic and measurable approach is required. This includes the deployment of comprehensive low-carbon strategies within each institution, support for eco-responsible care practices, and the promotion of energy and material efficiency.
At a broader level, partnerships with suppliers and local stakeholders are essential, especially to address indirect emissions (Scope 3) through sustainable procurement and responsible industrial collaboration. The French university hospitals have formalized this commitment through a national ecological transition pact, signed by all 33 CHUs. This collective effort highlights the importance of shared governance, mutual learning, and coordinated action-both nationally and internationally.
The French experience offers a replicable model of transition, where innovation, scientific evidence, and institutional leadership converge to reduce the ecological footprint of healthcare systems.
