Climate changes have a major influence on the overall health of the population. They are directly linked to the emissions of the greenhouse gases (GHG). The extent of GHG emission in relation to hemodialysis has been measured by several studies all over the world. Up to this date, no similar study has been conducted in Morocco. Therefore, the objective of our study is to conduct a review of the GHG emissions and to evaluate its specificities in order to establish a targeted action plan to reduce the ecological impact of hemodialysis in Morocco. To do this, we sought the help of a certified audit firm. Carbon Footprint tool (L'outil Bilan Carbon), established in Morocco in collaboration with Mohammed VI Foundation for the Protection of the Environment, was used to analyze the results collected for the year 2019. Our unit (conventional hemodialysis 3 × 4 hours, 424 m2, 24 generators, 80 patients, and 29 nursing staff) generates 408.98 tonnes of CO2 equivalent per year (t CO₂‐eq per year) or 5.11 TeqCO2 per patient per year. The largest contributors to GHG emissions are electrical energy consumption (28%), equipment purchase and services (27%), and staff and patients travel (22%). The use of renewable energy for the operation of hemodialysis centers can be a realistic solution to reduce the ecological impact of this type of healthcare in Morocco. [ABSTRACT FROM AUTHOR]
