Greening your small business.

Q: I am a self-employed independent contractor who works in various locations. I am concerned about the environment and try to do the right thing: I ride my bike or take BART to job sites whenever possible; I print on both sides of sheets of paper and then recycle the twice-used paper; and I handle most paperwork such as bills through e-mail rather than snail mail. Are there other things that small-business owners like me can do to be green? [ABSTRACT FROM PUBLISHER]
