By reducing print usage throughout the work place the following environmental impacts are reduced:
Forest and Trees
By reducing the number of pages printed trees and forests are saved. It takes between 17 and 31 trees to produce a ton of paper. Most laser printer paper purchased is of the 20lb weight class, and 1 ton of this paper would equate to approximately 200K 8 1/2 x 11 sheets of paper. If we assume the 17 trees per ton, then each tree would optimally produce 11,765 pages of 8 1/2 x 11. If you are using recycled paper it would of course be a percentage of this amount.
Ozone is released every time a print job takes place somewhere in the range of 24 to 79 ppb per page. This is dependent on printing rates, light intensity and maintenance status of the printer.
When a laser printer is in the print cycle it operates at 300-475 Watts compared to when it operates at idle 100 Watts or in power save mode sometimes as low as 45 Watts. This saved power saves you money as well as the environment as less coal needs to be burned in order to supply all the power to your workplace.
Office Air Quality
Emissions from laser printers, laser-printed paper and photocopiers contain VOCs ,chemicals which produce an increased physiological reaction upon subsequent exposures. Reducing these emissions will make for a cleaner, healthier, and happier work environment.
