WA launches investigation into repeated methane plumes at Chevron’s Gorgon LNG project
Western Australia is investigating Chevron's Gorgon LNG project after satellite monitoring detected five large methane plumes since November 2022. The latest emission rate was 7.8 tonnes per hour. The UN previously raised concerns, and regulators are determining the source and compliance actions. Gorgon, a major LNG producer, was expected to capture more emissions than it has. The investigation highlights challenges in monitoring and enforcing emissions from large gas projects.
