Action plan for the mitigation of greenhouse gas emissions in the hospital-based health care of the Hellenic Army.

Climate change is a growing threat for human health and well-being, one that will seriously impact and potentially disrupt all economic sectors and supply chains, such as trade, tourism, agriculture, forestry, and fisheries. The environmental impact of the delivery of medical and hospital care, which generates its own greenhouse gas emissions, needs to be examined and analyzed in detail in order to design and implement effective mitigation actions and measures. Hospital internal energy use processes include the energy consumed for hospital operation, such as lighting, heating, cooking, waste treatment, and other functions associated with the logistical and operational support of hospitals. The present research work, which follows the assessment undertaken in a previous study of the transport activities of the 401 Military General Hospital of Athens (401 MGHA), focuses on the carbon footprint of the stationary emission sources of the 401 MGHA; it serves as a second step in the development of an action plan for the mitigation of greenhouse gas emissions in the hospital-based health care of the Hellenic (Greek) Army. A portfolio of energy saving and emission reduction actions is proposed and mapped according to their abatement cost and greenhouse gas (GHG) reduction potential. The highest decrease of GHG emissions is expected to be materialized by the decarbonization of the Greek power sector due to the lignite phase-out and increased share of low carbon fuels and renewable energy sources. Significant emission reduction potential could also be achieved by the replacement of face-to-face hospital visits by telemedicine, primarily by reducing transport-associated emissions. Furthermore, a number of key performance indicators (KPI) are proposed as simple and easily monitored metrics of the hospital's performance towards its sustainable low carbon objectives. Specific KPIs per mitigation action are presented, as well as a general KPI that covers all mitigation actions and sources of emissions in the form of "tCO
