According to a report released Thursday by Ceres and the Clean Air Task Force, four energy companies in U.S .
Exxon Mobil, ConocoPhillips, Hilcorp and Occidental Petroleum are among the top emitters of both greenhouse gas and methane emissions in the United States ( U.S ).
The report is based on data submitted to the Environmental Protection Agency (EPA) by oil and gas producers.
The report found that the top companies’ methane emissions were 24 times higher than the lowest emissions.
U.S largest methane emitter
In 2020, Hilcorp will be the largest methane emitter, followed by Exxon; Occidental and ConocoPhillips stand in that order, according to the research.
The companies’ methane emissions totaled more than 300,000 metric tons.
The report found that equipment operation is a major source of emissions.
Companies that practice flaring or burning additional natural gas are found to have higher carbon dioxide emissions.
Companies that controlled for factors such as pressure and temperature – accounted for 62 percent of methane emissions.
Only oil and gas companies are require by law to submit the analyzed statistics to EPA.
Other emission sources, which account for 8 to 12 percent of industrial methane emissions, are not include in the data.
During the first 20 years, methane gas was more than 80 times more potent than carbon dioxide and was the source of about 0.5 degrees Celsius of global warming today.
Over the past few years, a review of the increasing emissions of methane has found that compared to other greenhouse gases, methane is more damaging to the atmosphere.
Therefore, climatologists have identified reducing methane emissions as one of the easiest ways to mitigate global warming.
Lesley Feldman, senior analyst at the Clean Air Task Force, said: “It makes clear what experts have known for a long time.
Oil and gas producers have steps to reduce their methane and other greenhouse gas emissions.”
“This report reflects some of the progress we are making to reduce greenhouse gas emissions from our operations,” an Exxon spokesman said.
In addition, they are implementing aggressive plans to reduce Scope 1 and 2 greenhouse gas emissions from their operations,” he said.
ExxonMobil says its global goal is to achieve net zero Scope 1 and Scope 2 greenhouse gas emissions from major operating businesses by 2050.
