Controversies[edit]

Lobbying to do business in Libya[edit]

The company began operations in Libya in 1965 and operated there until economic sanctions were imposed in 1986 by the United States.[8] The company was one of the first American companies to resume negotiations in Libya after the sanctions were lifted in 2004.[67] In 2008, the company, along with 5 other oil companies, was criticized for hiring Hogan Lovells to lobby to exempt Libya from a law written by U.S. Senator Frank Lautenberg (D-NJ) to assist American terror victims in seizing assets of countries found culpable in terror attacks, such as the Libyan bombing of Pan Am Flight 103 over Lockerbie in 1988.[68] and to remove a provision in the Dodd–Frank Wall Street Reform and Consumer Protection Act that requires disclosure of payments to foreign governments.[69] In early 2011, the company ceased exploration activities and production operations in Libya due to the growing civil unrest in the country and U.S. sanctions. In June 2011, the U.S. Securities and Exchange Commission and United Kingdom prosecutors requested information from the company, ExxonMobil and ConocoPhillips related to the Libyan Investment Authority (LIA), an investment firm controlled by Libyan leader Muammar Gaddafi, to determine if there were any violations of international bribery laws.[70][71] The Libyan Investment Authority's investments were frozen by the U.S. government in early 2011 following the Gaddafi regime's attacks on Libyan civilians.[70] In 2016, the company ceased operations in Libya.

Environmental record[edit]

In 2017, the company was ranked 55th on the Carbon Majors Report, a list of the Top 100 producers and their cumulative greenhouse gas emissions from 1988-2015.[72]


The company has stated that its use of enhanced oil recovery for a portion of its production is one way it helps mitigate its high emissions.[2][73]
