Go Green. At Zimmermann, we care about the environment and have become a Sustainable Forest Initiative (SFI) Certified printer. The SFI program was launched in 1994 as one of the U.S. forest sector's contributions to the vision of sustainable development established by the 1992 United Nations Conference on Environment and Development. SFI is an independent, non-profit organization and is responsible for maintaining, overseeing and improving a sustainable forestry certification program that is internationally recognized. It is the largest single forest standard in the world.

The SFI Standard is based on principles and measures that promote sustainable forest management and consider all forest values. It includes unique fiber sourcing requirements to promote responsible forest management on all forest lands in North America. When consumers see the SFI label on a product, they can be confident they are using paper from certified forests or certified sourcing.
