The Action Collaborative on Decarbonizing the U.S. Health Sector

Climate change is among the most important and urgent global health threats and opportunities of the 21st Century. 


NAM Initiative to Accelerate the National Climate and Health Movement

About the Program

Recognizing the critical need to address climate change through health sector leadership, the National Academy of Medicine (NAM) launched the Action Collaborative on Decarbonizing the U.S. Health Sector (Climate Collaborative), a public-private partnership of leaders from across the health system committed to addressing the sector’s environmental impact while strengthening its sustainability and resilience.

Climate change is increasingly affecting people’s health and the ability of the U.S. health care system to effectively respond to increases in extreme climate-related events. Improving the carbon footprint of the entire health ecosystem can drastically lower the approximately 8.5% of U.S. carbon emissions for which it is responsible, while also having significant health, social, and economic benefits. There is a need to activate all parts of the health sector for sustainable change.

The Climate Collaborative’s work focuses on health care supply chain and infrastructure; health care delivery; health professional education and communication; and policy, financing, and metrics.
