[Green dialysis and plant-based diets].

Human and planetary health are interconnected. The UN's Sustainable Development Goals aim for a healthy, peaceful world, but climate change - accelerated by human activity - is a major threat. Rising temperatures, water scarcity, pollution, and biodiversity loss contribute to worsening health crises. The healthcare sector itself is a major polluter, responsible for >5% of global CO₂ emissions. Chronic kidney disease (CKD) is increasingly linked to climate change, with extreme heat, air pollution, and water contamination exacerbating risks. Dialysis has a heavy environmental footprint, consuming vast amounts of water, energy, and plastic. Suggestions for development of a sustainable care system for kidney diseases are presented. To achieve sustainable nephrology, green dialysis and plant-based diets, are crucial. Reducing reliance on animal agriculture and ultraprocessed foods benefits both human and planetary health. Urgent action is needed to reform healthcare towards sustainability and align with the »One Health« approach, emphasizing the interdependence of human, animal, and environmental health.
