An urgent call for environmental accountability in nephrology clinical trials

The carbon footprint (CF) of the healthcare sector is estimated to account for 4.4% of the total world emissions of carbon dioxide equivalent (CO2e) [1]. Clinical trials (CTs) play a substantial role in knowledge and innovation, but require important human and material resources. Despite increasing global concern for environmental sustainability, few studies have assessed the environmental impact of CTs and the strategies to mitigate their effects [2]. All available reports emphasize the substantial CO2e emissions associated with CTs, yet just one specifically addresses nephrology trials. Recognizing this knowledge gap, the ERA Sustainable Nephrology Task Force (SNTF) calls for urgent attention and action to introduce sustainability in nephrology CTs.
