New report: Australia’s gas expansion puts the nation in harm’s way

Tim Baxter

Australia’s latest emissions data, which was released in early December 2020, contained one particularly startling, and unjustifiable, fact. Against all odds, in a year when emissions declined in almost every sector, Australia’s petroleum gas export industry still managed to inflict more damage on the climate.

A new Climate Council report released today, to which I contributed, sheds more light on the problem of Australia’s expanding gas industry.

It reveals in alarming detail how gas emissions are cancelling out the gains won by Australia’s renewables boom. It also shows how gas emissions are almost certainly under-reported, and uncovers the misleading claims underpinning the current Australian government’s gas-led economic recovery.

This is clearly an unsustainable state of affairs. Australia has this year been in the grip of a climate crisis: unprecedented drought, Black Summer bushfires, and another mass bleaching of coral in the Great Barrier Reef. The Australian gas industry escalates this risk and puts more citizens in harm’s way.

Gas: bucking the trend

In Australia, emissions from transport dropped by 24% compared with April– June last year, as people stayed out of cars and planes.


Emissions from electricity dropped by around 5% in the quarter, compared with the corresponding quarter in the previous year. This was mostly due to continued wind and solar expansion; demand for electricity dropped only marginally.

Overall, industrial demand for electricity was roughly the same as last year.

Meanwhile, although office blocks and shopping centres were shuttered, power was needed in the domestic sector to heat homes and charge iPads for home schooling.

Overall, almost every sector, including gas, also produced fewer emissions in the June quarter than occurred in the same period the year before. Across the economy, emissions for the quarter were 7% lower than the same period last year.

While emissions from the gas sector declined in the lockdown months, the sector’s poor emissions performance over the full 12 months to June meant it managed to increase its emissions over the year – one of the few sectors to do so.

How did gas get this bad?

Australia became the world’s largest exporter of liquefied gas in 2019. Our report shows almost three-quarters of gas extracted in Australia in 2019 was compressed and processed to send overseas.

Remarkably, on top of this, in 2019 the Australian gas export industry was itself the second-largest user of gas in Australia for the first time. More than one quarter of gas consumed in Australia was used to liquefy and chill gas for export overseas.

So the Australian gas export industry uses or exports nearly 80% of the gas it extracts each year – four times the amount needed to service the country’s own needs. Clearly claims of a shortfall

in domestic gas supplies, such as those used to justify the recent Narrabri Gas Project approval, are bogus.

A worse problem than we thought

The report shows rising gas emissions are cancelling out gains made by Australia’s record build of solar and wind generation capacity. Between 2005 and 2018 greenhouse gas emissions from the electricity sector fell by 15 million tonnes per year. However greenhouse gas emissions from the petroleum gas sector increased by 25 million tonnes per year in the same period.

Our report also highlights some serious problems with official estimates of gas emissions along the supply chain. The estimates are based on decades-old research designed for the US gas industry.

Australia also has been underestimating the harm caused by gas emissions. Methods used by the federal government to quantify the relative impact of methane are incomplete and ignore recent scientific advances. If methane’s effect was considered completely, this would further increase the assessed impact of the gas industry on Australia’s emissions.

Underpinning all this, the international gas market is in crisis as a result of a global oversupply. A drastic increase in Australia’s gas exports in recent years has left our nation dangerously exposed to international boom-and-bust market cycles, and subsequent job losses and power price volatility.

Most of Australia’s gas is expensive to produce compared with international competitors. The centrepiece of the federal government’s gas-led recovery, a stretch goal of A$4 per gigajoule for gas, has been described by the extract- ion industry’s own lobbyists as a “myth”. And several Australian export plants were recently declared by banking giant HSBC as “at risk”.

Seizing the opportunity

Fossil fuel extraction and consumption in Australia makes up 80% of our annual emissions. But as the Climate Council report shows, this figure is likely a gross underestimate. And of course, it does not account for the additional emissions produced when Australia’s gas exports are burned overseas.

COVID created a temporary blip in global emissions. If we don’t use it as an opportunity to consider a planet without coal, oil and gas consumption, the climate gains will amount to nothing.
