According to the Sierra Club, the average office worker uses about 10,000 pieces of copy paper every year. Obviously, one of the easiest ways to cut down on paper waste is to determine if what you need to print or copy is necessary. If it is, the organization says the next best thing is to avoid color printing and stick with black and white. When color printouts are not necessary, using only black and white settings reduces the toxicity load. Brightly colored hues have more chemicals, and printing these can lead to less healthy air quality in the office. And opt for settings that automatically do double-sided printing to cut your paper usage in half.
