I am astonished that the Institution has been hoodwinked by the CO2 hoax perpetrated by a bunch of environmental wackos.
There is not a shred of scientific evidence that increasing CO2 in the atmosphere is a potential threat to the wellbeing of the planet. In fact, there is a substantial body of fact which shows that it will be of considerable benefit to plant and animal life.
I suggest that your readers refer to the paper "Environmental Effects of Increased Atmospheric Carbon Dioxide" on pp. 79 - 90 of the Journal of American Physicians and Surgeons (2007) 12 before they waste any more time and effort in reducing their "carbon footprint".
