There are ways to save the environment in the office too.
We re-use the backs of printer paper for draft copies of documents and set our print quality to draft mode and grey-tone instead of colour.
We send e-confirmations instead of hard copies.
We purchase copy paper which is from recycled materials, and pay most of our bills by computer instead of using envelopes and stamps.
View faxes as e-faxes to save having to print them (especially if junk).
