In 1989, major fossil fuel and automobile companies formed the Global Climate Coalition (GCC), an industry front group that would spend over a decade blocking international climate action while publicly claiming the science was uncertain. Internal documents later revealed the coalition's own scientists had confirmed climate change was real and human-caused even as the organization publicly denied it.
The GCC was formed in response to growing scientific consensus on climate change and the prospect of international regulatory action. Founding members included ExxonMobil, Shell, Chevron, BP, Ford, General Motors, DaimlerChrysler, and major industry associations including the American Petroleum Institute, National Association of Manufacturers, and U.S. Chamber of Commerce.
The coalition's strategy centered on manufacturing doubt. It funded contrarian scientists, placed opinion pieces in major newspapers, and lobbied lawmakers to oppose emissions regulations. The GCC spent millions on advertising campaigns suggesting climate science was uncertain and that action would devastate the economy.
In 1995, the GCC's own scientific advisory committee produced an internal report acknowledging that the science of climate change was "well established and cannot be denied." The report noted that arguments against human-caused warming "do not offer convincing arguments against the conventional model of greenhouse gas emission-induced climate change." GCC leadership suppressed this finding and continued public denial campaigns.
The coalition was instrumental in preventing U.S. ratification of the Kyoto Protocol. Its lobbying contributed to the Senate's 95-0 vote against the treaty in 1997. The GCC disbanded in 2002 after major members including BP, Shell, and Ford withdrew amid growing public awareness of climate risks, but its denial template continued through successor organizations.
Documents released in litigation decades later proved the fossil fuel industry knew its products caused climate change and deliberately deceived the public, creating potential legal liability comparable to the tobacco industry's cancer denial.
