This is a great video about how to make your office greener. Many of us green our homes but we forget about the office. Watch this great video. The tip I'd like to highlight is turning off your computers at night. This is something that doesn't get done at many businesses. You can tell because when walking past them at night you can see screen savers or desktop screens through the windows. If for business reasons you can't turn off your computer at night, at least turn off the monitor.
