[Green nephrology: Assessment, prospects and practical applications].

Given the current climate stakes, implementing an ecological approach in nephrology departments and dialysis centers has become essential. Hemodialysis, which has a significant environmental impact, was the first activity to be targeted, with an assessment of its carbon footprint followed by best practice recommendations issued by the Green Nephrology Group of the Francophone Society for Nephrology, Dialysis, and Transplantation (SFNDT). Future areas of focus include completing studies on all dialysis modalities and addressing other domains such as transplantation, kidney disease prevention, and appropriate care. Knowledge of the carbon footprint of medications opens the way for eco-prescription, adding a new criterion to guide prescribing choices. This shift cannot take place without the involvement of patients.
