Products/services can include attributes such as: recycled content, reduced energy consumption, reduced toxicity, reduced air and water pollution impact, materials efficiency (such as packaging), and disposal impact at the end of useful life.
It is important to consider the overall cost of each purchase. A product that lasts only half as long as one that is slightly more expensive is no bargain. Similarly, a product that negatively affects other resources of the organization when it is used must be closely scrutinized for its net contribution to the organization's goals.
Before making a purchase, think about the 5 "R"s: Reduce, Reuse, Buy Recycled, Use Available Resources, and Recycle.
