Environmental Purchasing

King County’s Environmental Purchasing Policy reflects a long-term commitment to the purchase of environmentally preferable products. The King County Environmental Purchasing Program provides county personnel with information and technical assistance to help them identify, evaluate, and purchase economical and effective environmentally preferable products and services. Environmentally preferable procurement considers multiple product attributes, such as toxicity, durability, emissions, recycled content and conservation of resources, in addition to price, performance and availability. In 2009, King County agencies purchased 37.6 million dollars worth of environmentally preferable products, a 1.5 million dollars savings to county agencies.
