About Paper vs Digital Carbon and Savings Calculator
Free office estimator: monthly reams, virgin vs recycled share and double-sided ratio into CO2, trees and water saved by digitizing. No signup.
Paper math buyers understand
A virgin ream carries about 2.5 kg CO2e, 0.06 trees and 26 litres of water. Recycled stock roughly halves carbon and water. Monthly reams times those rates is a board-ready sentence.
Double-sided is free money
Duplex printing cuts sheet use toward half with zero workflow change. The tool applies your duplex ratio before computing savings, so the number survives scrutiny.
📐 Methodology & Reference Accuracy:

Frequently Asked Questions about Paper vs Digital Carbon and Savings Calculator
How much CO2 does printing use?
About 2.5 kg CO2e per virgin ream and 1.4 kg per recycled ream, before duplex savings. A 20-ream office prints roughly 50 kg a month.
How many trees is a ream?
Roughly 0.06 trees: one tree yields around 8,300 sheets. Twenty reams a month is over a tree a month.
Does recycled paper really help?
Yes. It roughly halves carbon and cuts water use by more than half versus virgin stock.
What about digital storage emissions?
Included as a small monthly offset you can adjust. Cloud storage is orders of magnitude smaller than the paper it replaces.
