What is Buying Green?

Environmentally Preferable Purchasing (EPP) is the procurement of goods and services that have a reduced impact on human health and the environment as compared to other goods and services serving the same purpose (Public Contract Code §12400-12404). In simple terms, EPP means “buying green.”  The law also states that the Department of General Services (DGS) is to provide state agencies with information and assistance regarding EPP. In response, DGS developed a best practices manual - the Buying Green Guide. This guide provides information, tools and tips for buyers and provides insight to suppliers on how the state views green products and businesses.
