The article discusses the potential of using non-denitrifying nitrous oxide (N₂O) respiration bacteria (NNRB) to reduce N₂O emissions from farmland. The authors developed a technology to enhance N₂O respiration by selecting NRB that thrive in soil, using organic waste as a substrate and vector. They focused on *Cloacibacterium* sp. CB-01, which was found to reduce N₂O emissions by 50–95% in field experiments, depending on soil type. The strong and long-lasting effect of CB-01 is attributed to its persistence in soil rather than its biokinetic parameters. Scaling up to the European level, the authors estimate that national anthropogenic N₂O emissions could be reduced by 5–20%, with potential for larger reductions if other organic wastes are included. The study highlights the potential of NNRB as a cost-effective method to mitigate N₂O emissions, which are significant contributors to global warming.The article discusses the potential of using non-denitrifying nitrous oxide (N₂O) respiration bacteria (NNRB) to reduce N₂O emissions from farmland.
