Oil Dependence Is a Dangerous Habit « Climate Progress: 

With that kind of money it’s no wonder Big Oil is doing everything in its power to maintain the status quo. The companies are spending record amounts on lobbying to stop clean-energy and climate legislation. The American Petroleum Institute spent $75.2 million for public relations and advertising in 2008, and in the third quarter of 2009 the oil and gas industry outspent all other sectors lobbying on climate change, with Exxon Mobil leading the pack spending $7.2 million.

Oil companies are also the main source of funding for API’s front group, Energy Citizens, which makes false claims that climate change legislation will be a national energy tax and job killer. In reality, passing clean-energy and pollution reduction legislation will be affordable and even save consumers money while creating a net of 1.7 million jobs.
