Look at these paper busting techniques. Produce hard copy only when necessary. If you have a document in your filing cabinet AND on your hard drive, this should be a red flag. If your organization requires you to file hard copy, or if you must send hardcopy somewhere, then produce it. Do not produce paper to archive information.
Paper makes a dreadful backup.
Receive faxes on your PC - not your fax machine. Feed that document in there. Shredding gives closure to the issue, and that is good for your mind. Shredding punctuates your decision to reduce paper. Scan hard copy.
