SFI Inc. is an independent, nonprofit organization dedicated to promoting sustainable forest management. We work with conservation groups, local communities, resource professionals, landowners and countless other organizations and individuals who share our passion for responsible forest management.


Our board of directors represents environmental, social and economic interests equally and we address local needs through a unique grassroots network of SFI Implementation Committees.

Our forest certification standard is based on principles that promote sustainable forest management, including measures to protect water quality, biodiversity, wildlife habitat, species at risk and Forests with Exceptional Conservation Value.

The standard is used widely across North America, and has strong acceptance in the global marketplace so we can deliver a steady supply of wood and paper products from legal and responsible sources. This is especially important at a time when there is growing demand for green building and responsible paper purchasing, and less than 10 percent of the world's forests are certified.
