A race to net zero-early lessons from healthcare's decarbonization marathon

Abstract

Climate change poses a threat to healthcare systems; at the same time, healthcare systems contribute to a worsening climate. Climate-induced disasters are predicted to increase both the demand for healthcare services while also posing a threat to the integrity of healthcare systems' infrastructures and supply chains. Many healthcare organizations have taken initiatives to prepare for such disasters through implementing carbon emission-reduction practices and infrastructure reinforcement, through globally recognized frameworks and strategies known as Scopes 1, 2, and 3, and decarbonization. We explored the efforts of these early adopters to understand how they are thinking about and addressing climate change's impacts on healthcare. Through a process of reviewing the peer-reviewed literature, publicly available published documents, annual sustainability reports, conference presentations, and participation in a national decarbonization collaborative, we (1) provide a diverse set of examples showcasing the variety of ways healthcare systems are responding; (2) identify a set of emergent key themes to implementing decarbonization practices, such as the role of an organizational culture of iterative improvement and building systems of cross-organizational collaboration; and (3) synthesize the identifiable set of driving factors for long-term sustainability of these decarbonization efforts.
