Australian regulator sues Japan’s Inpex over Ichthys LNG emissions breaches

SYDNEY, Aug 5 (Reuters) – The environmental regulator in Australia’s Northern Territory charged Japanese energy giant Inpex in court on Wednesday ​with under-reporting emissions from its Ichthys liquefied ‌natural gas (LNG) plant near Darwin.

The charges cover alleged licence breaches, such as the under-reporting of benzene and toluene emissions between 2019 and 2024, the Northern Territory ‌Environment ​Protection Authority said.

It gave ⁠no further details, saying ⁠the matter was in court. Inpex did not immediately respond to a request for comment.

The charges follow an October disclosure by Inpex of significant ​under-reporting of emissions at the plant, which prompted a regulatory review of operations at ⁠the facilities of both ⁠Ichthys LNG and Santos’ Darwin LNG.

The ​environmental licence from the regulator requires regular annual ​reports from Inpex on total air emissions.

The ‌review made 23 recommendations, endorsed by the regulator in July, for tougher rules at both LNG facilities, such as installment of continuous ⁠emissions monitoring equipment at major emission sources.

The regulator will draft amendments to existing licences this month reflecting the ⁠changes.

Climate group ‌Environment Centre NT called the ⁠decision to charge Inpex a “massive win ​for ‌Darwin residents”.

“Finally, we see INPEX being ​held accountable ⁠for massively underreporting the amount of toxic pollution it’s pumping into Darwin’s air,” said Bree Ahrens, one of the group’s activists.
