Cato Institute

Cato Institute


The Cato Institute is a libertarian think tank based in Washington, D.C. founded in January 1977 by Charles Koch, chairman of the “board and chief executive officer of Koch Industries, Inc., along with Edward H. Crane and Murray Rothbard.1“25 years at the Cato Institute: The 2001 Annual Report” (PDF), Cato Institute. Archived .pdf on file at DeSmog.

According to its website, “The mission of the Cato Institute is to originate, disseminate, and increase understanding of public policies based on the principles of individual liberty, limited government, free markets, and peace. Our vision is to create free, open, and civil societies founded on libertarian principles.”2“Cato’s Mission,” Cato Institute. Archived October 4, 2015. URL:

In addition to millions of dollars in support from its co-founders, the Koch Brothers, the Cato Institute has also received $125,000 from ExxonMobil since 1998. The Cato Institute has also been listed as one of Philip Morris’s “National Allies.” Cato’s corporate supporters have included both Philip Morris and R.J. Reynolds.3ExxonSecrets Factsheet: The Cato Institute. Archived October 3, 2020. Archive URL:

Other notable funders include Scaife Family Foundations, and the secretive DonorsTrust, a group that has been described as the “Dark Money ATM of the conservative movement.”4Farron Cousins. “The Dark Money Funding Climate Change Denial,” DeSmog, June 20, 2015.


The Cato Institute was originally incorporated (PDF) on December 19, 1974, under the name “Charles Koch Foundation,” with the original directors listed as Charles Koch, George Pearson, and Roger MacBride.  It shared the same address as Koch Industries in Wichita, Kansas.5Charles Koch Foundation (later Cato Institute), Certificate of Incorporation, organizational founding document, originally filed December 19, 1974. Archived .pdf on file at DeSmog.

At the same time, George Pearson filed the organization’s application for nonprofit status with the IRS (PDF), anticipating initial contributions of $40,000 in funds from Charles Koch, the Fred C. Koch Trust, and potentially the Fred C. Koch Foundation, as well as 10,000 to 15,000 shares of non-voting common stock of Koch Industries, as well as potentially non-voting preferred stock.6Application for Recognition of Exemption,” November, 1972.  Retrieved from the New Mexico Charitable Organizations Registrar. Archived .pdf on File at DeSmog.

The Cato Institute took on its current name in 1977. It began with headquarters in San Francisco, a staff of three, and $500,000 in financial backing provided via Charles G. Koch, according to the Washington Post.7Richard Morin. “Free Radical; Libertarian — and Contrarian — Ed Crane Has Run the Cato Institute for 25 Years. His Way,” Washington Post, May 9, 2002.

Internal Conflict

In 2012, the Koch Brothers and Ed Crane of the Cato Institute had a “bitter falling-out over management and philosophical differences.” The Koch Brothers, who controlled roughly half of the Cato Institute through “shareholder seats,” had decided to sue the Cato Institute to gain control over an additional seat of a shareholder who had died, which would give Koch majority control of the group.8Eric Lichtblau. “Cato Institute and Koch Brothers Reach Agreement,” The Caucus , June 25, 2012. URL:

Ed Crain released a written statement when the lawsuits were first filed:

“Charles G. Koch has filed a lawsuit as part of an effort to gain control of the Cato Institute, which he co-founded with me in 1977. While Mr. Koch and entities controlled by him have supported the Cato Institute financially since that time, Mr. Koch and his affiliates have exercised no significant influence over the direction or management of the Cato Institute, or the work done here.”9Allen McDuffee and T.W. Farnam. “Koch Brothers sue Cato Institute, president,” The Washington Post, March 1, 2012. URL:

The New York Times reported the Koch Brothers had long attempted to install their own people on the Cato Institute’s 16-member board, to establish a “more direct pipeline between Cato and the family’s Republican political outlets, including groups that Democrats complain have mounted a multimillion-dollar assault on President Obama.” This had caused tensions inside the governing structure, as Cato officials said this threatened their reputation for independent research.10Eric Lichtblau. “Cato Institute Is Caught in a Rift Over Its Direction,” The New York Times, March 6, 2012. URL:

The Kochs eventually relented on the condition that Ed Crane retire, who was later replaced by John Allison, reported the New Yorker. It also resulted in a revamp of the Cato’s organizational structure, which had based ownership on a share structure. David Koch would remain on the board, but not his brother Charles. Bruce Bartlett, conservative economist and historian, said that the Kochs are ”[P]utting in place a structure that will gradually erode Cato’s independence and move it closer to the American Enterprise Institute and Heritage Foundation.”11Jane Mayer. “The Kochs v. Cato: Winners and Losers,” The New Yorker, June 27, 2012. URL:

Greenpeace reported that before the attempted Koch takeover, Cato was seen as a “Relatively independent think tank, willing to criticize both democrat and republican administrations,” but that the Kochs had wanted “the power to fold Cato into their suite of other front groups, making it another Koch-controlled cog in the republican political machine.”12Why the Koch brothers are cannibalizing the Cato Institute,” Greenpeace USA, March 20, 2012.

Global Science Report

Paul C. “Chip” Knappenberger and Patrick J.

Climate Change is a regular topic at the Cato Institute’s Global Science report. Some sample articles below:

Stance on Climate Change

2013 – Present

The Cato Institute’s public statement on global warming claims they accept global warming is real, however subtly alludes to the group’s stance against climate policy, and suggests, contrary to the majority scientific view, that “there is ample time” to develop technology to combat it:

“Global warming is indeed real, and human activity has been a contributor since 1975. But global warming is also a very complicated and difficult issue that can provoke very unwise policy in response to political pressure. Although there are many different legislative proposals for substantial reductions in carbon dioxide emissions, there is no operational or tested suite of technologies that can accomplish the goals of such legislation. Fortunately, and contrary to much of the rhetoric surrounding climate change, there is ample time to develop such technologies, which will require substantial capital investment by individuals.”14Global Warming,” Cato Institute.

Patrick J. Michaels and Chip Knappenberger wrote a Cato Institute “working paper” making the “case for lukewarming”:15Climate Models and Climate Reality: A Closer Look at a Lukewarming World” (PDF)Cato Institute, December 15, 2015. Archived .pdf on file at DeSmog.

“[W]e conclude that future global warming will occur at a pace substantially lower than that upon which US federal and international actions to restrict greenhouse gas emissions are founded.

“It is high time to rethink those efforts,” they wrote.

October 17, 2016

According to an issue of Cato’s “Policy Analysis,” by Robert P. Murphy, Patrick J. Michaels, and Paul C. Knappenberger, in an article entitled “The Case Against a U.S. Carbon Tax”:16Robert P. Murphy, Patrick J. Michaels, and Paul C. Knappenberger. “The Case Against a U.S. Carbon Tax” (PDF)Policy Analysis No. 801 (October 17, 2016). Archived .pdf on file at DeSmog.

“Future economic damages from carbon dioxide emissions can only be estimated in conjunction with forecasts of climate change. But recent history shows those forecasts are in flux, with an increasing number of forecasts of less warming appearing in the scientific literature in the last four years.”


“If the case for emission cutbacks is weaker than the public has been led to believe, the claim of a double dividend is on even shakier ground. There really is a consensus in this literature, and it is that carbon taxes cause more economic damage than generic taxes do on labor or capital, so that in general even a revenue-neutral carbon tax swap would probably reduce economic growth.”

December 23, 2008

Patrick J. Michaels, with the Cato Institute, submitted comments to the EPA claiming that it should “EPA should not rely on the IPCC AR4 reports” in its proposal to regulate carbon dioxide emissions under the Clean Air Act:17“SHAKY SCIENCE: INCONVENIENT TRUTHS IGNORED BY EPA IN ITS PROPOSAL TO REGULATE CARBON DIOXIDE EMISSIONS” (PDF)Cato Institute, December 23, 2008. Archived .pdf on file at DeSmog.

Under Michaels’ general comments, he claims:18“SHAKY SCIENCE: INCONVENIENT TRUTHS IGNORED BY EPA IN ITS PROPOSAL TO REGULATE CARBON DIOXIDE EMISSIONS” (PDF)Cato Institute, December 23, 2008. Archived .pdf on file at DeSmog.

“As hurricanes are one of the leading causes of weather related damages in the U.S., and will likely remain so in the future, it is essential that any endangerment finding must recognize the complexity of this issue and that our best science currently suggests that our vulnerabilities largely arise from our climate and our behavior, rather than from human-induced climate change.”19“SHAKY SCIENCE: INCONVENIENT TRUTHS IGNORED BY EPA IN ITS PROPOSAL TO REGULATE CARBON DIOXIDE EMISSIONS” (PDF)Cato Institute, December 23, 2008. Archived .pdf on file at DeSmog.

He also claims that new findings regarding sea level rise somehow invalidate those used previously by the IPCC:20“SHAKY SCIENCE: INCONVENIENT TRUTHS IGNORED BY EPA IN ITS PROPOSAL TO REGULATE CARBON DIOXIDE EMISSIONS” (PDF)Cato Institute, December 23, 2008. Archived .pdf on file at DeSmog.

“Another major topic in which post-AR4 findings have had a major impact on our level of scientific understanding is on the rate of observed and future sea level rise […] All of these findings invalidate conclusions of the Endangerment Technical Support Document [TSD].”21“SHAKY SCIENCE: INCONVENIENT TRUTHS IGNORED BY EPA IN ITS PROPOSAL TO REGULATE CARBON DIOXIDE EMISSIONS” (PDF)Cato Institute, December 23, 2008. Archived .pdf on file at DeSmog.

According to Michaels, the endangerment finding report ignores increases in quality of life:22“SHAKY SCIENCE: INCONVENIENT TRUTHS IGNORED BY EPA IN ITS PROPOSAL TO REGULATE CARBON DIOXIDE EMISSIONS” (PDF)Cato Institute, December 23, 2008. Archived .pdf on file at DeSmog.

“The Endangerment TSD completely neglects constant advancement in fossil-fuel powered societies in the quality and length of life,” he wrote. “Whatever challenges that climate change—be it natural variations, or those borne from our own activities— may present us, our resourcefulness and quest for a better life will surely overcome them.”23“SHAKY SCIENCE: INCONVENIENT TRUTHS IGNORED BY EPA IN ITS PROPOSAL TO REGULATE CARBON DIOXIDE EMISSIONS” (PDF)Cato Institute, December 23, 2008. Archived .pdf on file at DeSmog.


In 2001, the Cato Institute released a “Handbook for Congress” that suggested that global warming cannot be stopped in the near-term: 

“No known mechanism can stop global warming in the near term. International agreements, such as the Kyoto Protocol to the United Nations Framework Convention on Climate Change, would have no detectable effect on average temperature within any reasonable policy time frame of 50 years or so, even with full compliance.”24“Cato Handbook for Congress: Policy Recommendations for the 107th Congress (2001) — Chapter 47” (PDF), Cato Institute. Archived January 24, 2001. Archived .pdf on file at DeSmog.


The Cato Institute includes early speeches on climate change by its former vice president Jerry Taylor on its website. For example, in a January 16, 1998 speech, Taylor declared:25Jerry Taylor. “Global Warming: The Anatomy of a Debate,” Cato Institute, January 16, 1998. Archived August 9, 2019. URL:

“As Cato Institute chairman William Niskanen has noted, for any international action to merit support, all of the following propositions must be proven true:26Jerry Taylor. “Global Warming: The Anatomy of a Debate,” Cato Institute, January 16, 1998. Archived August 9, 2019. URL:

  • A continued increase in the emission of greenhouse gases will increase global temperature.
  • An increase in average temperature will generate more costs than benefits.
  • Emissions controls are the most efficient means to prevent an increase in global temperature.
  • Early measures to control emissions are superior to later measures.
  • Emissions controls can be effectively monitored and enforced.
  • Governments of the treaty countries will approve the necessary control measures.
  • Controlling emissions is compatible with a modern economy.

“The case for any one of those statements is surprisingly weak. The case for a global warming treaty, which depends on the accuracy of all those statements, is shockingly weak.”

Taylor claims later in the speech that the costs of global warming would be low (emphasis added):27Jerry Taylor. “Global Warming: The Anatomy of a Debate,” Cato Institute, January 16, 1998. Archived August 9, 2019. URL:

“For what it’s worth, I tend to agree with the IPCC’s summary statement that the ‘balance of the evidence suggests’ that anthropogenic greenhouse gas emissions explain some of the detected warming observed thus far over the past 100 years. But as noted earlier, that warming has been extremely moderate, has been largely confined to the northern latitudes during winter nights, and has exhibited no real detrimental effects thus far. I expect those trends to continue and that’s the main reason why I doubt that the costs of warming will be particularly consequential.28Jerry Taylor. “Global Warming: The Anatomy of a Debate,” Cato Institute, January 16, 1998. Archived August 9, 2019. URL:

Referring to a warming scenario proposed by Patrick Michaels, who has advocated for inaction on climate change, he suggests global warming may be a good thing:29Jerry Taylor. “Global Warming: The Anatomy of a Debate,” Cato Institute, January 16, 1998. Archived August 9, 2019. URL:

“[This warming scenario predicts benign, not deleterious, effects on both the environment and the economy,” Taylor said of Michaels’ proposed scenario which refers to the supposed ”’fertilizer’ effect of CO2.”

Taylor claims that even 2.5 degrees Celsius of warming would be not “much reason for alarm”:30Jerry Taylor. “Global Warming: The Anatomy of a Debate,” Cato Institute, January 16, 1998. Archived August 9, 2019. URL:

“There have been six particularly comprehensive or prominent serious studies undertaken to estimate the macroeconomic consequences of such a warming. None of them gives us much reason for alarm,” Taylor claimed.

Studies he points to include work by economists including Thomas Gale MooreRobert Mendelsohn, and William Nordhaus.31Jerry Taylor. “Global Warming: The Anatomy of a Debate,” Cato Institute, January 16, 1998. Archived August 9, 2019. URL:

Electric Vehicles/Alternative Fuels


“The real reason for all the scandalous regulations and subsidies designed to shove us into underpowered mini-cars has nothing to do with ‘saving the planet.’  It’s all about doling out lucrative gifts (emissions credits, grants and subsides) to politically-favored companies who try to sell us unwanted electric cars or biofuels while the government punishes taxpayers and companies that produce vehicles American consumers really want” — Alan Reynolds, Cato Institute senior fellow.32Alan Reynolds. “Climate Change Can’t Excuse Electric Car Subsidies,” The Daily Caller, April 6, 2016.

Murray Energy Funding

Murray Energy bankruptcy filings in 2019 revealed the Cato Institute was among groups who received funding from the energy company owned by climate change denier Robert Murray. The filings revealed a wide range of creditors with deep ties to climate change denial including the Heartland Institute, the Competitive Enterprise Institute, Government Accountability and Oversight, and the International Climate Science Coalition. Robert Murray was known for being a major Trump donor, and giving officials a wish list of proposed actions to help the coal industry. See related reporting from The Intercept,34Lee Fang. “COAL GIANT PROVIDED SECRET FINANCING TO GROUP CHALLENGING CLIMATE LAWSUITS,”The Intercept, December 17, 2019. URL: Energy and Environment News,35Scott Waldman. “Murray Energy a major funder of climate denial groups,” E&E News, December 17, 2019. Archived December 20, 2019.

The Cato Institute hosted a lecture from UK Secretary of State for International Trade, Kemi Badenoch, where she discouraged world governments from taking action on climate change that would “impoverish” the UK and US, and instead encouraged them to use “free trade and investment to accelerate the technological progress that will protect the planet.”50UK and US must work together to promote free trade and future-proof our economies,” November 15, 2022. Archived January 30, 2023. Archive URL:

“We all know that climate change is a challenge for us all, wherever we live in the world. But we know that we can and should solve it by using free trade and investment to accelerate the technological progress that will protect the planet. And something that not enough politicians say, we must do this, we must protect the planet in a way that does not impoverish the UK, the US or let’s be honest any other country,” she said.

While serving in public office, Badenoch has changed her position twice on the UK government’s target of net zero carbon emissions by 2050, The Guardian reported.51Helena Horton. “Kemi Badenoch moves away from net zero by 2050, in double climate U-turn,” The Guardian, July 19, 2022.

Paul C. “Chip” Knappenberger, Assistant Director of the Center for the Study of Science at the Cato Institute, suggests that President Obama should back out of the Paris Climate pledge:62Paul C. “Chip” Knappenberger. “Time to Fess Up and Walk Back Our Paris Pledge,” The Hill (Online), March 24, 2016.

“Rather than pay the rest of the world to look the other way, the president should revise, or better yet, rescind that promise.

And now is the time to do that, before the grand signing ceremony of the Paris Climate Agreement that is scheduled for April 22, Earth Day, at the UN’s New York headquarters. Putting our name on a promise that we know we can’t keep would be a disingenuous act, painting the Paris Agreement not as a serious undertaking, but as a global publicity stunt.”63Paul C. “Chip” Knappenberger. “Time to Fess Up and Walk Back Our Paris Pledge,” The Hill (Online), March 24, 2016.

Patrick J. Michaels, the Cato Institute’s Director for Center for the Study of Science,” wrote an article in the Washington Examiner titled “What Should Pope Francis Say about Climate Change?

According to Michaels, free-market capitalism is the solution: 

“In the scientific community, there’s universal agreement that neither bad weather nor changing climate mean very much to rich societies. It’s the poor ones that can suffer greatly.  Consequently, the best way to deal with weather and climate is with economic development.”66Patrick J.

According to Rahn, “The good news is that mankind will probably adapt to climate change just fine, as we have been adapting since the end of the Ice Age. New studies show that to date, the benefits of global warming have been greater than the costs, and are likely to remain so for many more decades.”67Richard W.
