Environmental Impact

Calculation based on the figures from PaperCut, see previous post

Based on a 80,500 A4 sheets make up a tree
8.6g CO2 per sheet
17Wh per sheet

number = pages * copies;

tree = number / 80500 * 100; this makes it a percentage
carbon = (number * 8.6) / 1000; grams to kilograms
power = (number * 17 / 60; no conversion required, though may need to put it in kWh
