The Sustainable Forestry Initiative (SFI) is a sustainability organization operating in the U.S. and Canada that works across four pillars: standards, conservation, community, and education. SFI has two youth education initiatives: Project Learning Tree and Project Learning Tree Canada. SFI is the world's largest single forest certification standard by area. SFI is headquartered in Ottawa and Washington, D.C. In 2005, the Programme for the Endorsement of Forest Certification, which itself is the world's largest forest certification system, recognized the SFI standard. SFI standards The SFI 2022 Forest Management Standard covers key values such as protection of biodiversity, species at risk and wildlife habitat; sustainable harvest levels; protection of water quality; and prompt regeneration. SFI has certified more than 370 million acres (150 million hectares) to its standard in the United States and Canada. The SFI 2022 Fiber Sourcing Standard promotes responsible forestry practices based on 13 Principles, 11 Objectives, 29 Performance Measures and 59 Indicators that address the 90 percent of the world's forests that are not certified. The SFI 2022 Fiber Sourcing Standard distinguishes SFI from all other forest certification programs in that it sets mandatory practice requirements for the responsible procurement of all fiber, even if it is sourced from non-certified land. These fiber sourcing requirements include measures to broaden the practice of biodiversity, use best management practices to protect water quality, and utilize the services of forest management and harvesting professionals. Because it governs how SFI-certified organizations procure fiber from non-certified land, supporters argue that the standard encourages the spread of responsible forestry practices. SFI 2022 Chain-of-custody standard is an accounting system that tracks forest fiber content (certified forest content, certified sourcing and recycled content) through production and manufacturing to the end product. All SFI certifications require independent, third-party audits and are performed by internationally accredited certification bodies. The new set of SFI 2022 Standards and Rules, developed through an open review process, took effect on Jan. 1, 2022. The SFI 2022 Standards and Rules include new requirements in a number of areas. The SFI Climate Smart Forestry Objective requires SFI-certified organizations to ensure forest management activities address climate change adaptation and mitigation measures. The SFI Fire Resilience and Awareness Objective requires SFI-certified organizations to limit susceptibility of forests to undesirable impacts of wildfire and to raise community awareness of fire benefits, risks, and minimization measures. The new Objective 8, Recognize and Respect Indigenous Peoples’ Rights, ensures
