This guidebook provides an overview of some of the key steps and actions that senior leaders can initiate and support for their facility to move towards a climate-resilient, carbon netzero, and environmentally sustainable health system. Rather than a comprehensive overview, this document is intended to be a primer to help the long term care sector (LTC) with their transition to a greener system: from those starting their journey to those looking for new ideas to implement within an already robust sustainable system.
