Corporate Europe Observatory, 2010. Concealing their sources – who funds Europe’s climate change deniers? Brussels. They are a tiny minority, a network of just a few dozen individuals around the world. Their numbers contrast starkly with the overwhelming majority of scientists who agree on the reality of man-made climate change, and on the urgent need for action. But the voices of climate deniers, are amplified in Europe by a handful of extremist free marketers and right- wing think tanks, which try to block action to tackle climate change.

Global Warming Policy Foundation (2011) ‘900+ Peer-Reviewed Papers Supporting Scepticism Of “Man-Made”’ Global Warming Alarm’ Thursday, 14 April. https://www.carbonbrief.org/analysing-the-900-papers-supporting-climate-scepticism-9-out-of-top-10-authors-linked-to-exxonmobil. This report references a blog linking to more than 900 papers which, according to the authors, refute “concern relating to a negative environmental or socio-economic effect of anthropocentric global warming, usually exaggerated as catastrophic” However, a preliminary data analysis by the Carbon Brief revealed that nine of the ten most prolific authors cited have links to organisations funded by ExxonMobil, and the tenth has co-authored several papers with Exxon-linked contributors. The top ten contributors were alone responsible for 186 of the papers cited by the Global Warming Policy Foundation. The data also shows that there were many other familiar climate sceptic names among the major contributors to the list.

UCS (2015). The Climate Deception Dossiers. Internal Fossil Fuel Industry Memos Reveal Decades of Corporate Disinformation. Union of Concerned Scientists. This report presents seven “deception dossiers”—collections containing some 85 internal company and trade association documents that have either been leaked to the public, come to light through lawsuits, or been disclosed through Freedom of Information Act (FOIA) requests. While many of these documents have been analyzed by others (Oreskes 2011; Oreskes and Conway 2010; Gelbspan 1998), these dossiers offer the most complete and up-to-date collection yet available.

Union of Concerned Scientists (2007), Smoke, Mirrors & Hot Air: How Exxonmobil Uses Big Tobaccos Tactics to Manufacture Uncertainty on Climate Science. Cambridge, MA: Union of Concerned Scientists. According to this report, ExxonMobil has under- written the most sophisticated and most successful disinformation campaign since the tobacco industry misled the public about the scientific evidence linking smoking to lung cancer and heart disease. As this report documents, the two disinformation campaigns are strikingly similar. ExxonMobil has drawn upon the tactics and even some of the organizations and actors involved in the callous disinformation campaign the tobacco industry waged for 40 years.

Union of Concerned Scientists (2012). A climate of corporate control. How corporations have influenced the U.S. dialogue on climate science and policy. Washington, DC: Union of Concerned Scientists. To better understand the growing corporate influence on climate policies, this report analyzed the actions of many of the most highly engaged companies. The analysis reveals that while some American companies have taken consistent and laudable actions in support of climate science—and of consequent policy—others have worked aggressively to undermine the science and block science- based policy proposals. Still, other companies have taken contradictory actions in different venues.
