What does the BMJ video by Maisie and George indicate about the NHS's carbon footprint?

• A. The NHS is responsible for about a quarter of carbon production.
• B. The NHS has effectively eliminated its carbon footprint.
• C. The NHS accounts for no significant carbon emissions.
• D. The NHS carbon footprint is negligible compared to industry.

Answer: (A)

Understanding how to read a reported carbon footprint figure and what the scale means for action is being tested here. The video presents that the NHS accounts for about a quarter of carbon production, which signals a substantial share and makes the NHS a major focus for emissions reduction efforts within society. This magnitude matters because it shows that improvements in the health system—such as energy efficiency, sustainable procurement, lower travel emissions, and greener clinical practices—could yield meaningful, real-world impact on overall emissions. The other statements imply either near-elimination, no significant emissions, or a footprint that’s trivial compared with industry; these would understate the shown scale and misrepresent the NHS’s potential role in contributing to climate targets.
