Our shared responsibility: the urgent necessity of global environmentally sustainable kidney care

In response to Earth's accelerating climate crisis, we, an international group of nephrologists, call on our global community to unite and align kidney care in accordance with United Nation's 26th Conference of the Parties health sector principles. We announce a global and inclusive initiative, "GREEN-K": Global Environmental Evolution in Nephrology and Kidney Care, with a vision of "sustainable kidney care for a healthy planet and healthy kidneys" and mission to "promote and support environmentally sustainable and resilient kidney care globally through advocacy, education, and collaboration." A patient-centric approach that permits climate change mitigation and adaptation is proposed. Multi-stakeholder GREEN-K action and focus areas will include education, sustainable clinical care, and advances toward environmentally sustainable innovations, procurement, and infrastructure. Mindful of the disproportionately high climate impact of kidney therapies, we welcome the opportunity to work together in shared accountability to patients and Earth's natural systems.
