The '''American Tradition Institute''' (ATI) is a 501(c)(3) nonprofit headquartered in Washington, DC and in Denver, CO. According to its mission statement, the ATI is "a public policy research and educational foundation ... founded in 2009 to help lead the national discussion about environmental issues, including air and water quality and regulation, responsible land use, natural resource management, energy development, property rights, and free-market principles of stewardship."
:But "the Colorado-based American Tradition Institute is part of a broader network of groups with close ties to energy interests that have long fought greenhouse gas regulation. Our investigation also finds that ATI has connections with the [[Koch brothers]], [[Art Pope]] and other conservative donors seeking to expand their political influence," reported the Institute for Southern Studies in October 2011.<refname=iss>{{cite web
