The articles follow a format including these subheadings:
1) Why change is needed

• Outline the existing evidence base which shows that change is needed, or that there is a need for an area of healthcare practice to address its carbon footprint.

2) Evidence for the solution

• Outline the existing evidence base which shows that the suggested change is clinically acceptable.
• Where high quality evidence is not available, or the solution relies on assumptions (eg from observational data, or expert opinion) you state this.

3) What you can do

• Under the ‘What you can do’ subheading, please outline the suggested action or project in a systematic way so that a clinician, who may be new to sustainability in healthcare, would have a clear idea of how to actively implement your suggested change.
• Consider what readers can do immediately after reading the article, to take the action described (or take the first steps towards it).

4) What you need to know

• Include three bullet points which outline the three most interesting points in your article, or three things your reader may not already know. 

5) Education into practice
• This section is a way of encouraging your reader to engage more with your article by prompting them to reflect on their own practice, or to consider the challenge of implementing the suggested project in their own setting.

Please note, The BMJ won’t publish previously unpublished project reports or research. Instead, this aim is to provide an overview of the evidence and steps to implement around a sustainable action to allow readers then to implement it in their workplace or setting.
