British Petroleum
In 2016, British Petroleum was found guilty of criminal manslaughter, negligence and environmental crimes and was ordered to pay $20.8 billion - the largest fine ever levied by the Department of Justice of United States.
In April 2010, BP which was in a hurry to finish the Macondo Well - known as the well from hell - was blamed after the Deepwater Horizon oil rig blew out, causing a series of explosions, dumping more than 130 million gallons of oil into the Gulf of Mexico.
The company also paid an additional $525 million fine for hiding information from investors, and three of its employees were indicted on criminal charges.
