Ways to Build a Greener Healthcare System Comment on "A Review of the Applicability of Current Green Practices in Healthcare Facilities".

Green practices have become the responsibility of healthcare system in the current warming planet. The article by Soares and colleagues reviews the literature on circular economy implementation in the European Union (EU) and its application in healthcare system. In this commentary, we complement the findings by discussing ways to build a greener healthcare system and introducing life cycle assessment (LCA), a method to quantify the environmental impacts of products and services in healthcare. LCA is useful to compare the environmental impacts of different clinical products and pathways. Within the healthcare system, avoiding overdiagnosis and overprescribing, improving building energy efficiency, and fleet electrification are important green practices. In addition, we cannot ignore the differences in regional energy system when comparing the carbon footprint of different healthcare systems.
