Do they hold the key to printing and copying sustainability?

Do suppliers hold the key to sustainable development management information in printing and photocopying for an organisation?
Logically if suppliers of printing management systems (like Pcounter, Uniflow, papercut, etc.), were to count power consumption (uptime, running and standby) for , every machine and for every image produced and sheet of paper, used they could assign a carbon value to each factor* and this would show the whole life carbon footprint of the machine and the amount of paper used.
These factors* could be assigned a cost and from that a cost of ownership and idea if costs are getting higher or lower over time, so if the machine is becoming more or less efficient and effective.
This would clearly show the paper purchased, that is actually used by that printing system and the leakage.
Then we will be able to show the efficiency, actual paper use, by the printing system, carbon savings and the leakage of paper that is used on other printers.
Even if we just put in the paper as A4 & A3 80gsm white paper, we would all get a much clearer picture of printing across our organisations and times of peak demand.
