UN alerts Chevron to massive methane plumes over Gorgon LNG facility
Satellite data have identified large, recurring methane clouds above Chevron's Gorgon LNG plant on Barrow Island, prompting a United Nations warning.
Independent satellite monitoring has repeatedly detected substantial methane plumes rising from Chevron's Gorgon liquefied natural gas complex on Barrow Island, with five Tanager-1 passes since November capturing the emissions. The most recent pass in late August measured an average release of roughly 7.8 tonnes of methane per hour, exceeding the U.S. EPA's definition of a "super emitter." The United Nations warned Chevron that methane contributes about 25% of global warming and is 80 times more potent than CO2.
Chevron confirmed receipt of the warning and said it is working with the UN Environment Programme, though UNEP has not yet received formal feedback from the company or Australian officials. Western Australia's Department of Water and Environmental Regulation is investigating the reports to assess any needed compliance or regulatory steps, while the Conservation Council WA criticized the lack of coordinated government action. Experts suggest the emissions may stem from the plant's acid gas removal units, indicating a possible operational issue.
Why it matters
Methane leaks from a major LNG project could intensify climate change and trigger regulatory scrutiny.
