different manners, the ATFS (American Tree Farm System), FSC (Forest Stewardship Council), and SFI systems include the fundamental elements of credibility and make positive contributions to forest sustainability. No certification program can credibly claim to be ‘best’, and no certification program that promotes itself as the only certification option can maintain credibility." Green Building Council On April 5, 2016, the U.S. Green Building Council issued a Leadership in Energy and Environmental Design (LEED) pilot alternative compliance path (ACP) designed to screen out illegal forest products from LEED buildings. While the ACP is being tested as a credit, it will ultimately become a prerequisite that applies to all LEED projects. As a pilot, the ACP does not become a permanent part of the LEED standard without an affirmative vote of the USGBC membership. The ACP pilot recognizes all certified sources – FSC, PEFC, SFI and ATFS and programs. The ACP will apply to all LEED v4 rating systems including Homes v4 and to all LEED 2009 rating systems. The ACP categorizes the various forest certification standards based on the ASTM D7612-10 (2015) standard, which is titled “Categorizing Wood and Wood-Based Products According to Their Fiber Sources.” ASTM (American Society for Testing and Materials) International is a globally recognized leader in the development and delivery of voluntary consensus standards. Other green building tools, including two American National Standards Institute (ANSI)-approved rating systems in the United States – ANSI-ICC 700–2008: National Green Building Standard and ANSI/GBI 01-2010: Green Building Assessment Protocol for Commercial Buildings (formerly Green Globes U.S.) – Green Globes and Built Green Canada recognize wood products certified by credible third-party certification programs like SFI. Conservation organizations SFI is supported by conservation groups such as the American Bird Conservancy, Ducks Unlimited Canada, Arbor Day Foundation, American Forests, and the Canadian Parks Council (all of which serve on the SFI Board). Unlike SFI, the FSC included environmental groups such as Greenpeace among its founders. The National Wildlife Federation and World Wide Fund for Nature (WWF) currently serve on the FSC Board. The Sierra Club endorses only FSC. Critiques of SFI Marketing practices On September 9, 2009 the Washington State Forest Law Center, on behalf of the environmental protection group ForestEthics, filed complaints against SFI Inc. with the Federal Trade Commission and the Internal Revenue Service. The FTC complaint accused SFI Inc. of misleading consumers with deceptive marketing practices. The complaint cited various aspects
