Carbon Footprint of Dental Practice

Hi, I recently had a carbon footprint calculated for my 5 surgery dental practice and had an action plan produced to help reduce the amount of CO2 we're responsible for. However, I don't have anything to compare our footprint with, as I don't know any other dental practices that have had a carbon footprint done.

We are responsible for about 54tonnes of CO2 being produced per year from our energy use, waste and employee travel. This will be higher if we factor in how our patients travel to us.

Has anyone else had a carbon footprint completed for their dental practice, or does anyone know of any data on average carbon emissions from dental practices?

Thanks, Katie
