'' journal published a paper reporting that the global warming projections and models created by ExxonMobil's own scientists between 1977 and 2003 had "accurately" projected and "skillfully" modeled global warming due to fossil fuel burning, and had reasonably estimated how much would lead to dangerous warming. The authors of the paper concluded: "Yet, whereas academic and government scientists worked to communicate what they knew to the public, ExxonMobil worked to deny it."
Between the 1980s and 2014, ExxonMobil was a notable denier of climate change, though the company officially changed its position in 2014 to acknowledge the existence of climate change. ExxonMobil's prolonged response incited the creation of the ''Exxon Knew'' movement, which aims to hold the company accountable for various climate-related incidents. ExxonMobil has used its own website to attack ''Exxon Knew'', claiming that it is a coordinated effort to defame the company.

Oil spills and plastic pollution

ExxonMobil's operations have been subject to numerous oil spills both before and after the 1999 merger. The most widely publicized oil spill was the 1989
''Valdez'' oil spill, where an Exxon tanker discharged approximately 11 million U.S. gallons (42,000 m3) of oil into
Prince William Sound,
oiling of the remote Alaskan coastline. The spill remains the second largest in American history, only trailing

ExxonMobil was also responsible for various other oil spills across the world. Some of Exxon's largest and most notable oil spills in the United States include long-lasting oil leaks totaling into an estimated 30 million gallon spill into New York City's

(resulting in about $135 million in damages),
and a 2012 1,900 barrel (80,000 gallon) spill from the company's
Baton Rouge Refinery in the rivers of
Point Coupee Parish, Louisiana.
ExxonMobil's actives in Louisiana in particular, especially its
Baton Rouge Refinery, have given the area the nickname of ''
Cancer Alley''. The company's activities, along with other operations and refineries in the area, have been the source of increased cancer infections, lower air quality, and as seen by some, potential environmental racism committed by the company.
In May 2021, ExxonMobil topped the Plastic Waste Makers Index report published by the Minderoo Foundation of 20 petrochemical companies that manufactured 55 percent of the
single-use plastic waste in the world in 2019 (which were part of a larger group of 100 petrochemical companies that manufactured 90 percent of the waste), while in April 2022,

, alleging that the company carried out a "decades-long campaign of deception" and misled the public on the merits of plastic recycling; in response ExxonMobil said that California has an ineffective recycling system that officials have known about for decades.
Geopolitical influence and human rights violations
ExxonMobil has also been accused of human rights violations and abusing its geopolitical influence.
In the book ''Private Empire'' by
Steve Coll, ExxonMobil is described as extremely powerful "corporate state within the American state" in dealing with the countries in which it drills, going to the point as describing such countries' governments as "constrained". The company's corporate ancestors are also blamed for the outbreak of the 1954
Jebel Akhdar War, which was sparked by the
Iraq Petroleum Company's activities.
Indonesia
Beginning in the late 1980s, ExxonMobil (through predecessor Mobil) hired military units of the
Indonesian National Army to provide security for their gas extraction and liquefaction project in

, Indonesia, and these military units were accused of committing human rights violations, including sexual assault, battery and unlawful detention. ExxonMobil eventually pulled out from Indonesia completely in 2001, while denying any wrongdoing. Exxon attempted to have the case dismissed nine times, dragging the lawsuit out for over 20 years. In July 2022, a
US District Court denied ExxonMobil's motions to dismiss the case, clearing the way for the lawsuit to go to trial, although no trial date was set. In 2023, ExxonMobile settled the case a week before trial.
