This month, all the main articles in the issue come from a special collection on sustainable healthcare, climate science and the anaesthetist. All papers are free to read, forever!

Our Associate Editor, Dr Ben Gibbison, has chosen three of his favourite from the issue to discuss. These include an editorial on misconceptions about sustainable anaesthesia, a review of background science on global warming potentials and a comparison of the environmental impact of volatiles vs. TIVA in 50k patients.
