Green Purchasing Networks
Local purchasing networks allow cities and towns to reduce transportation costs and reduce greenhouse gases by pooling their resources to reduce prices and provide opportunities for local vendors.
Purchasing networks generally have more power to purchase "environmentally preferable" products and services – those that have a reduced negative impact on the environment and human health. Many municipalities have found that environmentally preferable products actually work as well or better than traditional products, and in many cases, can be more cost-effective.

Their "Green Initiative" is designed to provide a one-stop source for public agency access to a broad line of environmentally certified products and services.
