What is your neurological carbon footprint?
Carbon emissions contribute to climate change. Climate change affects health.1 Knowing our carbon footprint is the first step to improving this situation. Below are some calculated emissions relevant to a neurologist. Carbon dioxide equivalent (CO2e) is a standard unit for measuring carbon footprints; kgCO2e is the amount of CO2e in kilograms. It expresses the impact of each different greenhouse gas in terms of the amount of CO2 that would create the same amount of global warming.
Carbon footprint for brain scans:i
MR brain non-contrast scan = 10 kgCO2e …
