10. Refill ink printer cartridges instead of throwing them away and adding them to a landfill. Not only is this more environmentally friendly than buying new ones, it can be less expensive as well.

9. Implement a recycling program around the office; recycle all paper products, plastic bottles, glass, and aluminum cans. Contact your local government to see if they offer a program to recycle old electronics or donate old equipment to shelters and non-profit organizations instead of throwing them out.

8. One of the biggest ways to reduce your carbon footprint is to reduce carbon emissions. Not only will this help the environment but it can also save money. Encourage employees to carpool together, bike to work, or take mass transit. As an added incentive, consider offering to pay for employees' mass transit passes or preferred parking for employees who carpool.

7. Get an energy audit from your local utility company; many offer free consultations to show you how to reduce energy use and subsequently save money.

6. Go paperless. Encourage emailing, printing only when necessary, and using scrap paper for scratch. Accept online payments from customers and offer paperless billing.

5. Replace high-energy use incandescent light bulbs with more eco-friendly CFL bulbs. They may cost slightly more initially but use 75% less energy and last ten times longer than conventional light bulbs.

4. When the weather begins to warm, before turning on the air conditioning, try opening the doors and windows; it may be enough to cool down the office without wasting energy and money.

3. If possible, curb business travel and opt to conduct meetings via the Internet using video conferencing, email, and VoiP (voice over Internet Protocol) technologies.

2. Purchase green, sustainable products and office supplies that are recycled, refurbished, or used. Make the eco-friendliness (or lack thereof) a priority when purchasing, not just price.

1. Turn off equipment, such as printers, faxes, and computers when not in use - doing so can save nearly 25% of the energy your office uses. You may also want to consider actually unplugging the equipment at the end of the day; equipment that is off but still plugged in uses some power (known as phantom or vampire power), so unplugging will reduce further energy waste.
