American Enterprise Institute (AEI)


The American Enterprise Institute (AEI), or American Enterprise Institute for Public Policy Research, is one of the richest and most influential think tanks in the U.S. having received significant funding from conservative foundations and large corporations. AEI’s areas of concern include foreign and domestic policy which includes the issue of global warming.1“Factsheet: American Enterprise Institute for Public Policy Research,” ExxonSecrets. Archived September 7, 2012. Original URL.

The American Enterprise Institute (AEI) describes itself as a “private, nonpartisan, not-for-profit institution dedicated to research and education on issues of government, politics, economics and social welfare,” with their primary research divisions being Economics, Foreign and Defense Policy, Politics and Public Opinion, Education, Health, Energy and the Environment and Society and Culture. They are a “community of scholars and supporters committed to expanding liberty, increasing individual opportunity and strengthening free enterprise.”2About,” American Enterprise Institute.

While AEI states that “As a tax-exempt educational organization governed by Section 501(c)(3) of the Internal Revenue Code, AEI is generally prohibited from attempting to influence legislation in the U.S. Congress or other legislative bodies,” they also state that individual scholars and fellows “frequently do take positions on policy and other issues, including explicit advocacy for or against legislation currently being considered by the Congress.” However, AEI asserts that when they do, “they speak for themselves and not for AEI or its trustees or other scholars or employees.”3About,” American Enterprise Institute.

American Enterprise Institute-Brookings Joint Center for Regulatory Studies

In 1998, AEI and the Brookings Institution established this joint venture with the purpose of studying federal regulatory policy. The Center would be directed by Robert Hahn of AEI and Robert Litan of the Brookings Institution. The Joint Center is no longer in operation, according to the Internet Archive of their website (as of 2009).6Snapshot of at, March 4, 2009. Archive URL:

Stance on Climate Change

 July 21, 2015

According to Mark J. Perry, resident scholar at the American Enterprise Institute, “Hydraulic fracking causes environmental damage, greater use of shale gas will exacerbate climate change, and the natural gas carried by the pipelines is not intended for American consumers but rather will go to export markets. Each of these three claims is completely baseless.”10Michael J. Perry. “Nonsensical ‘fractivist’ pipeline hysteria,” The Washington Times, July 21, 2015. Archived August 20, 2015. Archive URL:

The American Enterprise Institute’s head of energy studies, Benjamin Zycher, has suggested there is doubt about man-made climate change:11Benjamin Zycher. “The Fact-free Opposition to Keystone XL,” The American Enterprise Institute, February 5, 2014. Archived August 20, 2015. Archive URL:

“The issue of the climate sensitivity of the atmosphere to increasing GHG concentrations is nowhere near resolution.”

“[T]ornado, hurricane, and cyclone activity are at historically low levels, wildfires are in a long-term decline except in government forests, there is no trend in sea-levels related to increases in GHG concentrations, the record of the Arctic ice cover is ambiguous, there is no drought trend since 1895, and the same is true for flooding over the last 85-127 years.”

Leading economist Jeffrey Sachs discusses Zycher’s claims in an article in the Huffington Post, titled “How the AEI Distorts the Climate Debate,” where he challenges the AEI  “to come clean.” Sachs wrote:

The AEI, despite its roster of distinguished academics, has failed to be constructive in the climate debate. It’s time that the AEI puts forward a strategy to achieve the globally agreed objective of avoiding dangerous anthropogenic interference with the climate system.12Jeffrey Sachs. “How the AEI Distorts the Climate Debate,” Huffington Post, February 8, 2014.

Christopher DeMuth, writing at “Energy Crunch,” an AEI publication, declared that “The Kyoto Treaty Deserved to Die”:13The Kyoto Treaty Deserved to Die,” The American Enterprise Online. Archived June 5, 2008. Originally published in Energy Crunch, September 2001.

“The key features of the climate change debate are large degrees of uncertainty and a long time horizon. Although it is fairly well-established that the Earth’s atmosphere has warmed somewhat (one degree Fahrenheit) during the past century, it’s not clear why this happened. The warming may have been due to human impositions (the burning of fossil fuels and other incidents of industrial growth), or to natural solar or climate variations, or to some of each. Whatever the causes, we don’t know if future warming trends will be large or small, or whether the net environmental and economic consequences (including both beneficial and harmful effects) may be large or small.”


The AEI was sixth on a list of organizations that received the highest climate skeptic funding between 2011 and 2013, reaching $5.7 million in total, The Guardian reports in their article titled “Secretive donors gave US climate denial groups $125m over three years” that examines money flows from DonorsTrust and Donors Capital Fund.14Suzanne Goldenberg and Helena Bengtsson. “Secretive donors gave US climate denial groups $125m over three years,” The Guardian, June 9, 2015.

AEI resident scholar Paul H.

Archived May 21, 2021. Archive URL:

In the article, Kupiec discusses The Central Banks and Supervisors Network for Greening the Financial System (NGFS).

“The NGFS is committed to the belief that climate change and environmental risks endanger the safety and soundness of the financial system in the guise of floods from rising sea level, greater storm intensity, wildfires, and other real or imagined environmental plagues, like ‘air pollution, water pollution and scarcity of fresh water, land contamination, reduced biodiversity and deforestation’,” he wrote.

Kupiec predicts “environmentally sustainable financial policies will experience a similar cycle of failure and revision” to efforts to maintain monetary stability. He concludes: “will the NGFS successfully create a new form of ‘transitional risk’ linked to climate-change fanaticism? Time will tell.”
