[The Green Nephrology Group of the SFNDT: initial reflections].

Preserving the environment is becoming a universal priority. Human activities must be redesigned to best adapt them to available resources and to reduce their deleterious impact on the planet. The Green Nephrology Group of the “Société française de néphrologie, dialyse et transplantation” (SFNDT) has started a reflection on these issues, in particular on dialysis, a vital treatment but with high carbon production, associated with high water consumption. The data available on these points are presented such as, among others, the collection of indicators and action plans, the recycling of waste from water treatment, the reduction of dialysate flow, the reuse and regeneration of spent dialysate as well as calculations of carbon emission by dialysis activity. Architectural experiences are reported as well as the regulatory constraints applying to manufacturers and organizations in the sector. Potential solutions require the mobilization of all stakeholders, ranging from patients to health authorities, including caregivers, pharmacists, technicians, nephrologists and facility managers. They will be formalized very soon in a guide being prepared by the SFNDT Green Nephrology Group.
