American Tradition Institute
American Tradition Institute (ATI)
The American Tradition Institute was launched in Colorado in February 2009 as the nonprofit Western Tradition Institute, later changing its name to ATI. WTI, in turn, was a spinoff of the Western Tradition Partnership (WTP) — a 501(c)(4) political advocacy group backed by energy interests.
According to their website, the American Tradition Institute is a "public policy research and educational foundation – a 'think tank' – 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."
During the 2010 elections, the Montana Commission of Political Practices found that ATI organization broke state campaign laws by failing to register as a political committee or report its donors and spending.
The state suggested WTP/ATP was involved in corruption and money laundering. They found that it solicited unlimited contributions to support candidates and then passed them through a "sham organization," the Bozeman-based political action committee The Coalition for Energy and the Environment that ran attack ads against Democrats. WTP told corporations that it aimed to combat 'radical environmentalists' and 'beat them at their own game' and that their contributions would remain secret." 
According to a 2010 filing with the IRS (PDF), ATI received $40,000 from its sister group ATP, which in turn is supported by oil, gas and coal interests.
It received another $5,000 from the Atlas Economic Research Foundation, a Virginia-based think tank that, according to ExxonSecrets, received over $1 million in funding from Exxon Mobil since 1998. Atlas also received $122,300 from the Koch foundations and $735,000 from the Pope foundation. 
Stance on Climate Change
An online petition hosted by the American Tradition Institute opposing cap and trade makes the following assertions about climate change: 
". . . the claims of carbon-driven anthropogenic global warming (AGW) are unproven and are, in fact, contested by over 31,000 scientists..."
". . . global temperatures have not risen since 2000 and data from the National Oceanic and Atmospheric Administration demonstrates that the earth has actually been cooling for the last 4 years..."

- Christopher C. Horner — Director of Litigation, Environmental Law Center.
- Paul Chesser — Director, Communications & Research.
- Tom Tanton — Acting Executive Director, Director, Science & Technology Assessment.
