Here is my green tip
Set up a separate bin for recycling paper, sell it to recycling companies and use the cash to get new recycled paper.
Go paper less, digitalize as many of your docs as possible. You will get paid by recycling the unused paper and save in document management and storage space in your office. Implementing digital backups systems will make your data more secure.
Implement a paperless invoice management system. This will save in mailing costs.
Send your server top the cloud using visualization products like VMware and Citrix XenAppto run multiple virtual machines on single server. This will save you money in hardware, IT administrators, power, and software updates.
