I use total intravenous anaesthesia for virtually all my anaesthetics and it is clear that this is one of the more environmentally friendly anaesthetic agents to use as it contributes to far fewer greenhouse gas emmisions than desflurane which is has the hightest greenhouse gas equivalence of the commonly used general anaesthetic agents available in Australia. There is a growing movement within the anaesthesia community to remove desflurane entirely from contemporary anaesthetic practice and I am fully in support of this goal.
