5 KNOWLEDGE emissions generated? Note: The figures come from different studies from different hospitals in different countries and are therefore only comparable to a limited extent. In this article, CO2 equivalents also fall under the term CO2 for simplification. CT = computed tomography; MRI = magnetic resonance imaging. The global healthcaresystem is responsible for 4.4% of CO2 emissions, and would rank fifth among the countries with the highest CO2 emissions [1]. KLINIKUM Heute: Up to1/3 of total hospital emissions [4] Anaesthetic gases: Imaging in hospitals per year: approx. 13 million MRI and CT: 17.5 and 9.2 kg (Ø) per scan, respectively [9] Catering: approx. 18% of hospital emissions [5] [8] 4. https://www.bund-berlin.de/fileadmin/berlin/publikationen/Klimaschutz-pdf/Fact-Sheet_Narkosegase_und_Klimaschutz_Update.pdf (accessed 26.06.2023) 5.
