In the December 2017 edition of The Lancet Planetary Health, Taylor and Mackie contributed a new article, "Carbon foot printing in health systems: one small step towards planetary health."
The issue looks broadly at carbon foot printing of hospitals, health care, and specifically in surgical theatre. Creating and tracking metrics is a key first step, but Taylor and Mackie want to push the conversation farther:
[Establishing a price for carbon] is a necessary step, but we should be under no illusions. It is no longer sufficient to simply quantify the problems we face; health-care systems need to be much more effective stewards of the resources placed at their disposal.
