After days of delay, state regulators confirm probe into methane plume at Chevron

Key points

• The West Australian government has confirmed it is investigating repeated large methane emissions from Chevron's Gorgon gas project off the Pilbara coast. The regulator had earlier been unclear whether it had jurisdiction over the plumes, which a United Nations-linked satellite has observed for the past year.
• A government spokesperson said the department was engaging with Chevron to find the cause. Chevron did not comment on the investigation.
• A Greens MLC said it was embarrassing that the regulator had not been monitoring the emissions.
