A Greenpeace investigation has identified a little-known, privately owned US oil company as the paymaster of global warming sceptics in the US and Europe. Greenpeace says that Koch Industries donated nearly $48m (31.8m) to climate opposition groups between 1997-2008. From 2005-2008, it donated $25m to groups opposed to climate change, nearly three times as much as higher-profile funders that time such as oil company ExxonMobil. Koch also spent $5.7m on political campaigns and $37m on direct lobbying to support fossil fuels. Greenpeace accuses the funded groups of spreading inaccurate and misleading information" about climate science and clean energy companies. "The company's network of lobbyists, former executives and organisations has created a forceful stream of misinformation that Koch-funded entities produce and disseminate. The propaganda is then replicated, repackaged and echoed many times throughout the Koch-funded web of political front groups and thinktanks," said Greenpeace. The groups include many of the best-known conservative thinktanks in the US, like Americans for Prosperity, the Heritage Foundation, the Cato institute, the Manhattan Institute and the Foundation for research on economics and the environment.
