Green Procurement/Environmentally Preferable Purchasing

Hidden environmental impact of manufactured goods. Think about the various stages manufactured goods must go through before they come to the end users as finished products. Raw materials must be harvested, transported, and processed into components, using equipment and processes that consume energy and have impact on the environment themselves. Chemical components are synthesized using industrial-scale processes. Components are then assembled into finished products, sometimes after having been transported to assembly plants, then wrapped in packaging and transported either directly to the end user or to a distribution center to be purchased by the end user. Maintenance and operation may require the continual input of energy and chemicals. Certain classes of manufactured goods may exhibit toxicity to people and the environment. At the end of the service life, complex disposal issues due to hazardous components become apparent.

Green Procurement at Lehman College. Lehman College uses a paperless, electronic procurement system for each step of the purchasing process; purchases only green cleaning products for Buildings & Grounds activities - which has removed entire classes of hazardous materials from cleaning products used at the College; purchases products made from post-consumer materials wherever possible; uses only recycled-content paper at Lehman’s Copy Center and in many departments, and encourages duplex (double-sided) printing wherever possible; and encourages researchers to purchase the smallest amounts of chemicals needed for their research, which cuts down on disposal costs and decreases chemical hazards on campus. Energy Star electrical appliances, which have significantly lower energy requirements, are purchased wherever possible.

Where can individuals find guidance on Environmentally Preferable Purchasing? Environmentally Preferable Purchasing guidelines have been developed by EPA and other federal, state, and local government agencies, and are often targeted to government and other municipal entities, large organizations, businesses and other large consumers of manufactured goods (and services). However, these guidelines can also instruct individuals on factors to consider when choosing more environmentally-friendly manufactured products. To give just a few examples, please also visit the Environmental Paper Network and Conservatree, which have a wealth of information about paper manufacture, its history, and its profound impact on the environment. The Electronic Purchasing Environmental Assessment Tool (EPEAT) provides environmental assessments of many specific computers and components, something which should be considered as they contain many hazardous materials.
