UN warns Chevron over repeat methane plumes detected at WA gas facility

Key points

• The United Nations Environment Program has warned Chevron after satellites detected high methane levels on five flyovers between November and August. The readings are linked to Chevron's Gorgon gas plant on Barrow Island, off the Pilbara coast.
• The latest release was equal to burning 110 tonnes of coal, and the plant was emitting methane at 7.8 tonnes per hour in August. Chevron says satellite readings carry a wide range of uncertainty and that it is seeking further clarification.
• The company says it reports its emissions in line with Australian rules.
