(CNN) -- You work in an office, you have no control over your immediate environment, right? Wrong. There are plenty of things you can do at work to make a difference.
How green is your office?
1) Photocopy and print on both sides of the paper
For the last 30 years people have been predicting the imminent arrival of paperless offices. There's no need for the stuff thanks to email and the Internet you might say, but look around you, there's piles of the stuff all over the place.
According to Abigail Sellen and Richard Harper authors of "The myth of the paperless office" the use of e-mail in an organization causes an average 40 percent increase in paper consumption.
And if you must print at least recycle it afterward.
Fact: If an office building of 7,000 workers recycled all of its office paper waste for a year, it would be the equivalent of taking almost 400 cars off the road in terms of CO2 emissions. (Source: U.S. Environmental Protection Agency)
2) Turn off your computer screen when leaving your desk
If you're going to be away from your desk for more than 15 minutes, you can save more than 50 percent of the energy that would have been consumed by your computer in your absence. (Source: Australian Department of Environment)
3) Encourage environmentally friendly company policies
You don't need to do a green audit of your company, but there are some small things you can do. Is you pension being invested in un-ethical companies or those that pollute the environment? Find out. If you haven't got a recycling bin for plastics, paper, cans and glass, find out why not.
