UN sends warning to Chevron after plumes of methane found over Gorgon project

Well, this is good news for the current account balance:

Independent satellite monitoring has detected massive plumes of methane emerging from one of Australia's largest oil and gas complexes.

The persistent clouds above Chevron's Gorgon liquefied natural gas (LNG) plant on Barrow Island off Western Australia's Pilbara coast were picked up by five consecutive passes of the Tanager-1 satellite since November last year.

The most recent, in late August, recorded an average emission rate of about 7.8 tonnes of methane an hour.

That is the equivalent of burning more than 110,000 kilograms of coal within a span of 60 minutes, calculated using an online tool by the US Environmental Protection Agency (EPA).

The repeated detections, the latest far exceeding a "super emitter" event under US EPA guidelines, prompted a United Nations (UN) warning to Chevron.

According to the UN, methane is responsible for about 25 per cent of global warming and is a greenhouse gas 80 times more harmful than carbon dioxide
