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.
