醫院碳盤查結果與減碳策略

Results of Hospital Carbon Footprint Verification and Carbon Reduction Strategies

醫療機構為高耗能與高碳排產業，根據「臺灣2050淨零排放路徑」，政府有必要輔導醫療體系進行碳盤查與碳揭露。然而台灣醫療業碳排放僅佔國家整體碳排放4.6%，故未優先納入列管行業。高雄市某地區醫院新建醫療大樓於2021年7月啟用，自願率先進行全面碳盤查，根據行政院環境部氣候變遷署《溫室氣體排放量盤查作業指引》，排放來源盤查涵蓋二類：直接排放(範疇一)、能源間接排放(範疇二)。設定以2022年為基準年，全面盤查二大類，結果顯示醫院實際排放量為12公噸CO2e/年，然而外購電力竟達到2,478公噸CO2e/年。由此可知醫療產業應朝向導入能源管理，運用低碳能源(太陽能、熱泵、風力)與提升資源效率等，以利降低碳排放量，進而邁向醫療永續發展。

Medical institutions have relatively high rates of energy consumption and carbon emissions. According to Taiwan’s Pathway to Net-Zero Emissions in 2050, the government aims to guide the green transition of the medical industry by requiring Carbon Footprint Verification and Carbon Disclosure reports. However, as the medical industry in Taiwan accounts for only 4.6% of overall national carbon emissions. Therefore, it is not considered a prioritized industry. A new medical building at a district hospital in Kaohsiung City began official operations in July 2021. It has embraced green transition values by voluntarily conducting Carbon Footprint Verification reports. According to the Guidelines for Greenhouse Gas Emission Inventory produced by the Ministry of Environment, the emissions include two categories: direct GHG emissions (Scope 1); and indirect GHG emissions (Scope 2). The hospital set 2022 as the base year, subsequently conducting a comprehensive investigation. The results reveal that the actual emissions of the hospital are 12 metric tons of CO2e/year, while the purchased electricity reached 2,478 metric tons of CO2e/year. To reduce carbon emissions, the medical industry should apply comprehensive energy management strategies, use low-carbon energy sources to improve resource efficiency, and adopt sustainable development goals.
