Background: The climate crisis is one of the greatest threats to public health and surgery is a significant contributor to carbon emissions generated by the NHS. In this paper, we describe our experience of sustainable operating by using evidence-based methods to reduce our carbon footprint across three neurosurgical theatres during our 'Green operating day'.
Methods: The Green operating day was run at a single site over a 12-hour operative day and included 10 neurosurgical cases.
