Supporting Decarbonization of Health Systems-A Review of International Policy and Practice on Health Care and Climate Change.

Purpose of review: Healthcare is a significant contributor of carbon emissions, which contribute to climate change. There has been an increased focus on the role healthcare should play in reducing emissions in recent years. This review, completed in September and October 2022, explored national commitments among 73 countries to reduce emissions from healthcare and the policies and delivery plans that exist to support their implementation.

Recent findings: Whilst some countries such as Norway, Columbia, and Australia are working to understand current emissions and develop plans to reduce them, few have published delivery plans for meeting national targets. Broader policies and reports published to date provide a clear set of actions that healthcare can take to reduce emissions. However, more research, innovation, and service redesign will be needed to close the gap to net zero healthcare. Some health systems are already taking action to reduce their emissions. However, national incentives, including standardized metrics and reporting, can help drive broader action and pace of delivery.
