National Center for Public Policy Research (NCPPR)
The National Center for Public Policy Research (NCPPR) was founded in 1982 as a free market think tank and “communications and research foundation supportive of a strong national defense and dedicated to providing free market solutions to today’s public policy problems.” 
In the 1980s NCPPR “helped change public opinion through vocal national campaigns aimed at supporting Reagan administration initiatives,” but they have since shifted their focus to topics such as environmental policy. For example, in 2005 the Center fought against the 1973 Endangered Species Act in order to reduce the government’s power to regulate private land use. As part of their effort, they formed a “grassroots coalition of dozens of groups to educate the public and Members of Congress.” 
In their own words, the Center says they are “Firm in the belief that private owners are the best stewards of the environment.” NCPPR‘s National Center’s Center for Environmental and Regulatory Affairs “advocates private, free market solutions to today’s environmental challenges.” 
Stance on Climate Change
The National Center for Public Policy Research released a paper by Amy Ridenour titled “Top Ten Reasons Washington Should Not Impose New Global Warming Laws or Regulations.” The following are included among the “top ten reasons” listed include: 
- “The Earth hasn’t warmed since the Clinton Administration;
- New global warming laws and regulations harm people, and harm lower-income and minorities disproportionately;
- U.S. energy-related CO2 emissions already fell 12.6 percent between 2005 and 2012, while worldwide emissions went up 17.7 percent during the same period;
- The climate models upon which President Obama’s belief in human-caused catastrophic global warming is based do not work – since 1979, over 96 percent of climate models predicted more warming by now than has taken place;
- Claims that 97 percent of scientists endorse the global warming theory are propaganda.”
The National Center for Public Policy Research released a “Earth Day 2002 Fact Sheet” that contained the following statement on global warming (*Note that the petition NCPPR refers to is the Oregon Petition, which has had its credibility questioned by numerous sources, including whether it includes fake signatures ):
“Claims that scientific opinion is nearly unanimous on the subject of global warming are wrong. The Oregon Institute of Science and Medicine received signatures* from over 17,100 basic and applied American scientists, two-thirds with advanced degrees, to a document saying, ‘There is no convincing scientific evidence that human release of carbon dioxide, methane, or other greenhouse gasses is causing or will, in the foreseeable future, cause catastrophic heating of the Earth’s atmosphere and disruption of the Earth’s climate.’ 
“… There are many indications that carbon dioxide does not play a significant role in global warming.” 
Comments Surrounding 2021 Capitol Insurrection
NCPPR‘s Project 21 was among dozens of the individuals and organizations profiled in DeSmog’s Disinformation Database who posted online or gave interviews about the events surrounding the Jan. 6, 2021 Capitol insurrection. Some posted claims of election fraud, similar to those that drove the Stop the Steal rally on Jan. 6. Some circulated dubious information about the insurrection itself. DeSmog has preserved a selection of notable posts related to the events of Jan. 6, 2021, including some that were later deleted or removed.

Center for Environmental and Regulatory Affairs (CERA) Experts
June 12, 2018
In a letter to then-EPA Administrator Scott Pruitt and Transportation Secretary Elaine Chao sent by NCPPR’s Project 21 Black Leadership Network, Horace Cooper praised the decision to reduce CAFE fuel economy and emissions standards. 
Cooper and his co-chairmen suggested Obama-era regulations would have a negative impact on minority communities:
“The Black community has been prevented from reaching its full potential not only by racial factors, but by non-racial ones as well. Excessive regulatory costs that make products unaffordable are one of the most significant non-racial obstacles to black economic progress.” 
The letter also requested future regulatory proposals take into consideration potential economic effects on minorities prior to approval. 
May 8, 2017
The National Center for Public Policy Research, represented by David Ridenour, is listed on an open letter to President Donald J. Trump urging him “to withdraw fully from the Paris Climate Treaty and to stop all taxpayer funding of UN global warming programs.” 
DeSmog reported that the 40 groups represented in the letter, including the Competitive Enterprise Institute (CEI), The Heartland Institute, and the Heritage Foundation, have received a combined total of millions of dollars from the Koch Brothers, ExxonMobil, and other industry groups. 
Analysis also showed that the groups accepted about $80 million through Donors Capital Fund and Donors Trust, two groups that have been confirmed is a key financial source for key U.S-based climate change denial groups. 
April 23, 2016
Jeff Steir, director of the Risk Analysis division at the National Center for Public Policy Research, authored an article in Newsweek titled “Why Are They Hiding the Good News About Fracking?“  The Heartland Institute also promoted the study, quoting Steir.  Noble Energy, a Colorado oil and gas company, also picked up and republished Steir’s story. 
Steir claims that researchers whose study reportedly found no evidence for fracking’s contamination of drinking water had put “politics before science” by “not spending a sufficient amount of time publicizing the study’s results.” 
“Concerns about groundwater contamination are baseless,” Steir writes. “the study demonstrates that fracking is a safe source of jobs, prosperity and low-cost energy.” 
March 15, 2016
The National Center for Public Policy Research was among roughly 100 groups listed on an ExxonMobil Subpoena sent by Virgin Island Attorney General Claude E. Walker requesting correspondence between the oil company and think tanks responsible for questioning the science behind climate change. 
Walker’s subpoena is part of a concerted effort of 17 attorneys general, who joined together in a coalition “deal with climate change,” as described by New York Attorney General Eric Schneiderman. The investigations started in light of a 2015 article by InsideClimateNews that suggested Exxon’s own researchers had confirmed fossil fuels’ role in global warming in the late 1970s to early 1980s. , 
June 3, 2015
At a Google shareholder meeting, the National Center for Public Policy Research presented a shareholder resolution suggesting Google “come clean with investors about the risks associated with its alternative energy projects – many of which receive lavish taxpayer subsidies that may not continue indefinitely,” reads the NCPPR press release. 
A video excerpt of the meeting, featuring the National Center’s Free Enterprise Project Director Justin Danhof, is available below:
April 28, 2015
When the president of the American energy company Exelon supported proposed emissions regulations under the Obama Administration, the National Center for Public Policy’s Research Executive Director David W. Almasi tried to change his mind in an Exelon Shareholder Meeting. 
Almasi cited a study by the Heritage Foundation (an organization which itself received over $680,000 from energy giant ExxonMobil) that suggested emissions controls would raise the price of electricity and “destroy 500,000 manufacturing jobs and 45 percent of all coal-mining jobs.” 
March 10, 2015
National Center Free Enterprise Project Director Justin Danhof attended the Apple shareholder meeting in Cupertino, California on behalf of the NCPPR where he contributed a resolution opposing alternative energy investment.
According to the NCPPR‘s press release, “the National Center for Public Policy Research introduced a shareholder resolution asking the tech giant for more transparency about the risks associated with its alternative energy investments.” 
July 28, 2014
The National Center for Public Policy Research offered a positive review of climate change skeptic Tim Ball‘s book, “The Deliberate Corruption of Climate Science” in the Summer, 2014 newsletter. NCPPR describes Tim Ball as a “thorn-in-the-side of dishonest scientists everywhere and supporter of your National Center for Public Policy Research.”
According to the NCPPR description, “The Deliberate Corruption of Climate Science explains how a small group of committed leftwingers led by Canadian anti-capitalism activist Maurice Strong seized upon ‘climate change’ as their issue and the United Nations as their vehicle to trick governments and populations into believing ‘the only hope for the planet [is] that industrialized civilizations collapse’.” 
They quote Ball saying that “The entire exercise of global warming and climate change is a deception.” 
June 2, 2014
The National Center for Public Policy Research released a new paper titled “Top Ten Reasons Washington Should Not Impose New Global Warming Laws or Regulations” by NCPPR Chairman Amy Ridenour. 
According to the NCPPR‘s press release, “President Obama’s new climate rules for existing power plants, expected to be announced by the Environmental Protection Agency Monday morning, are unnecessary.” 
Jebruary 21, 2014
The National Center for Public Policy Research announced that “After years of meetings, shareholder proposals, media campaigns, protests and activism, the National Center for Public Policy Research received a commitment from General Electric that the international conglomerate will no longer engage in any environmental project solely to address so-called climate change concerns.” 
The NCPPR had previously submitted a shareholder proposal “for inclusion in GE‘s 2014 proxy statement and annual meeting materials that sought certain commitments regarding the company’s sustainability operations and carbon dioxide reduction efforts.” The proposal “request[ed] that the Board of Directors adopt a policy that General Electric not undertake any energy savings or sustainability project for the sole goal of seeking carbon dioxide emissions reductions due to climate change concerns, except as required by law.” 
“For years, GE has been the poster boy for crony capitalism and corporate America’s green energy cheerleader. Now, GE shareholders have confirmation that the company’s strategies will henceforth be led by true market forces and not by blind adherence to global warming zealotry,” said Justin Danhof, Esq., NCPPR‘s director of the National Center for Public Policy Research’s Free Enterprise Project. 
The National Center for Public Policy Research published a blog post titled, “Climate of Confusion: Global Warming ‘Science’ a Blizzard of Contradictions.” 
The post states:
“In less than a week, two back-to-back blizzards have pummeled and paralyzed much of the East coast, bringing snow accumulations of 50-plus inches to the D.C. area and breaking records for snow accumulation in D.C., Baltimore, Philadelphia, and Atlantic City … So what’s going on here? Global warming, of course. At least, that’s what ‘experts’ are telling us.” 
Lobbyist Jack Abramoff, now a convicted and sentenced felon, was a member of NCPPR‘s Board of Directors until his resignation in October 2004 after NCPPR concluded he had violated the organization’s conflict of interest policy.
In October 2002, Abramoff told President Amy Ridenour to send the Mississippi Band of Choctaws an invoice for $1 million. He then told Amy to distribute the funds as follows: “$450,000 to the Capital Athletic Foundation, $500,000 to Capital Campaign Strategies and $50,000 to a company called Nurnberger and Associates, run by a Mr. Ralph Nurnberger.” 
Greenberg Traurig, the firm employing Abramoff, sent $1.5 million to NCPPR in June, 2003. Following directions, Ridenour distributed $250,000 to Capital Athletic Foundation and the remainder ($1,250,000) to Kay Gold LLC. According to her testimony, Amy Ridenour believed that Kay Gold was owned by Abramoff’s associate, Michael Scanlon.
“It was not until 2004 that I learned that this money did not come from the Choctaw, but rather from an Internet gambling company apparently unrelated to the Choctaw Tribe […] I would have never issued any money to Kaygold if I had known that Jack was the owner because this was a clear violation of the National Center’s conflict of interest policy, which Jack had signed,” she said. 
Some reporters have written that NCPPR repeatedly wrote articles that aligned with the positions held by Abramoff, “suggesting possible coordination between the lobbyist and the group in violation of federal law.” 
February 8, 1998
According to the article, the letters targeted senior citizens, with “so-called ‘fright mail,’ computer-generated by self-proclaimed public policy organizations in mostly legal but controversial campaigns to raise cash.”
Amy Moritz Ridenour of NCPPR admitted that “her organization sent donors up to a dozen major pitches a month. The appeals are sent on four different letterheads. She said anyone receiving more than a dozen solicitations in a month probably was on mailing lists the National Center has ‘rented’ from other organizations, which she said were outside her control.”
The article also revealed that in 1995, NCPPR spent more than 77 percent of the $2.3 million it had raised that year on fundraising. The Council of Better Business Bureaus standards say fund-raising costs should not exceed 35 percent of contributions raised.

Envirotruth (Now Defunct) — 2002
In 2002, NCPPR launched a “Envirotruth” project, which received at least $30,000 in funding from ExxonMobil according to SourceWatch. The website no longer appears to be in operation, and hit has removed itself from the Internet Archive. 
According to EnviroTruth, the climate change consensus is a “Myth,” quoting climate change denier Fred Singer:
“’There is of course no consensus at all,’ according to Dr. Fred Singer, President of The Science & Environmental Policy Project and Distinguished Research Professor at George Mason University and Professor Emeritus of environmental science at the University of Virginia. ‘There isn’t even a consensus on whether the atmosphere is currently warming – never mind on whether humanity should be held responsible.’” 
EnviroTruth claims that “environmental groups have seized the world stage and the public’s attention by distorting facts, bending the truth and even committing acts of terrorism against innocent citizens.” 
- “Humanity is the primary cause of global climate change.”
- “Climate change is occurring at an unprecedented rate.”
- “Sea level is rising quickly and it will get worse if the polar ice caps melt due to global warming. Coastal settlements and low-lying islands will be submerged.”
- “Recent global temperature rise has been dramatic.”
- “Humanity is causing earth’s polar regions to warm quickly resulting in unusual rates of ice melting.”
Envirotruth published the following list of “Experts Who Contest Kyoto’s Scientific Foundation and Alternative Energy,” as well as an accompanying guide on “The Myths of Climate Change and Renewable Energy”: 
|The Myths of Climate Change and Renewable Energy|
|Myth #||Myth Description|
|1||Humanity is the primary cause of global climate change.|
|1a||Computer models show catastrophic warming in the future.|
|1b||The consensus of world scientists, as revealed by the UN‘s IPCC, agree – humanity is causing significant climate change.|
|1c||Climate change is occurring at an unprecedented rate.|
|2||Recent global temperature rise has been dramatic.|
|3||The buildup of human induced greenhouse gases, and carbon dioxide (co2) in particular, will cause a catastrophic planetary warming.|
|4||If the earth warms, it will be disastrous for the environment and human society.|
|5||Extreme weather events are expected to be more common if the world warms. This has already started – drought, floods, forest fires, etc. are on the rise as a result of our greenhouse gas emissions.|
|6||Sea-level is rising quickly and it will get worse if the polar ice caps melt due to global warming. Coastal settlements and low-lying islands will be submerged.|
|7||Humanity is causing earth’s polar regions to warm quickly resulting in unusual rates of ice melting.|
|8||Kyoto will save thousands of lives by cutting air pollution.|
|9||Solar and wind power can soon be significant contributors to the base load energy needs of Canada.|
NCPPR maintains numerous “Departments” including:
