Raw numbers are meaningless if there is nothing to compare with.
I have no idea if 2 kg of CO2 is at all a big quantity, medium or small. I guess the situation is similar to most of the humans.
I suggest to provide some rudimentary examples of carbon emission: 100 km run by a car, hours of your refrigerator, years of life of a human breathing O2 and expiring CO2, among other ideas. I guess which one to choose would depend on the magnitude of carbon to be displayed and compared with)
