Australia is among the many world’s prime three exporters of LNG and second-largest exporter of coal. When burned abroad, these exports lead to 1.1 billion tonnes of carbon dioxide emissions a 12 months – virtually thrice Australia’s home emissions.
Emissions embedded in Australia’s exports don’t rely in the direction of our nationwide emissions targets. However they contribute to local weather change – and so they’re the rationale for Australia’s worldwide popularity as a fossil-fuel financial system.
On the intense facet, Australia boasts enormous potential for low-cost renewable power and a knack for useful resource industries.
We are able to, and will, grow to be a “renewable energy superpower”. This time period refers back to the potential for Australia to make use of its bountiful renewable power assets to make commodities akin to iron, ammonia and different merchandise and fuels in “green” or low-emissions methods.
So how does Australia give salience to this concept on the worldwide stage, whereas our fossil gasoline exports proceed? The answer might be a brand new net-zero goal for Australia, through which emissions from inexperienced exports are tallied up in opposition to these from fossil gasoline exports.

Reinvigorating Australia’s local weather coverage
If the clear power transition eventuates, inexperienced exports from Australia will rise over time. This can assist cut back the usage of coal, gasoline and oil elsewhere on the earth.
In the meantime, coal exports – and later, gasoline exports – will fall. This can occur no matter Australia’s insurance policies, because the world financial system decarbonises and demand for fossil fuels slows.
Sooner or later, we are able to anticipate emissions averted by our inexperienced commodity exports to surpass these from remaining coal and gasoline exports. Australia would then attain what might be termed “net-zero export emissions”.
Adopting this net-zero goal as a nationwide coverage would give a concrete yardstick to Australia’s green-export ambitions. It may additionally invigorate Australia’s local weather coverage and increase investor confidence.
A distinct strategy could be to set targets just for inexperienced exports, and this might be how we get began. In the end, a net-zero goal wrapping up each inexperienced and fossil-fuel exports would converse most on to the objective of tackling local weather change, and is prone to have extra impression on the worldwide stage.

Attending to net-zero exports
The under chart reveals an illustrative decline in emissions embedded in Australia’s coal and LNG (liquified pure gasoline) exports, out to 2050.*
Authors’ calculations primarily based on Australian Power Replace 2024, Australian Nationwide Greenhouse Accounts Elements 2024, IEA World Power Outlook 2024
It’s exhausting to pin down when Australia may attain net-zero exports. It depends upon a number of components. How rapidly will the price of clear power and green-commodity applied sciences fall? How competitively can Australia produce inexperienced items in comparison with different nations? What insurance policies shall be adopted in Australia and abroad – and can they work?
The magnitudes are sobering. Take iron, for instance. Australia presently exports 900 million tonnes of iron ore a 12 months. That is processed abroad to about 560 million tonnes of iron.
To totally compensate for emissions presently embedded in Australia’s coal and gasoline exports, Australia would wish to course of about the identical quantity of inexperienced iron – round 550 million tonnes – on house soil yearly.
To achieve this determine, we assume 0.1 tonnes of CO₂-equivalent is created per tonne of inexperienced iron, in comparison with about 2.1 tonnes of CO₂-equivalent per tonne of iron ensuing from standard blast furnace manufacturing.
Attaining this may require preserving iron ore manufacturing at present ranges and processing all of it in Australia, which is unlikely to be practical.
Fortunately, the duty of reaching net-zero export emissions shall be smaller in future, as world coal and gasoline demand falls. However precisely how this can translate to Australian exports is very unsure.

Let’s suppose Australia’s exports developed on the identical trajectory as they could beneath present local weather insurance policies and pledges for the worldwide coal and gasoline commerce.
On this case, embedded emissions from Australia’s coal and gasoline exports could be about 360 million tonnes in 2050. This consists of about 120 million tonnes from LNG exports – a lot of it locked in by the extension to Woodside’s North West Shelf mission off Western Australia.
Hypothetically, the 360 million tonnes of emissions might be negated by a mixture of inexperienced exports. They embody 102 million tonnes of inexperienced iron (saving 204 million tonnes of CO₂), and 11 million tonnes of inexperienced ammonia (saving about 23 million tonnes of CO₂), and the rest lined by a mixture of inexperienced aluminium, silicon, methanol and transport fuels.
Judgement calls could be wanted about which commodities to incorporate within the goal. The composition of inexperienced exports prompt above is akin to assumptions about Australia’s potential world market share outlined by The Superpower Institute.
Importantly, it’s exhausting to foretell with certainty the greenhouse gasoline emissions displaced elsewhere on the earth by Australia’s inexperienced exports. So, the estimates needs to be understood as broad illustrations, and never as actual because the accounting used to calculate international locations’ home emissions.
The exact 12 months chosen for reaching a net-zero goal for export emissions could be much less necessary than the dedication that, sooner or later, Australia’s inexperienced power exports will exceed fossil gasoline exports. This may set up the notion that Australia has the capability and willingness to assist the world decarbonise.
Sooner or later, Australia’s inexperienced power exports will exceed fossil gasoline exports.

A constructive agenda for change
The export goal might be a part of Australia’s up to date emissions pledge attributable to be submitted to the United Nations by September this 12 months. The pledge, referred to as a Nationally Decided Contribution (NDC), is required by signatories to the Paris Settlement.
Every nation is predicted to element its nationwide emissions goal for 2035. However nations could make extra pledges in the direction of the world’s local weather change effort. You may name it an “NDC+”.
So Australia may define an indicative objective for net-zero exports – maybe alongside different pledges akin to leveraging local weather change finance for creating international locations, or serving to our Pacific neighbours adapt to local weather change impacts.
As a big fossil fuels exporter, Australia would earn kudos for displaying it has a constructive agenda for change.
And if Australia wins the bid to host the COP31 local weather convention subsequent 12 months, a plan to cut back export emissions might be a significant rallying level.
* Underlying information for the chart displaying an anticipated decline in future emissions embedded in Australia’s coal and LNG exports:
Exports in 2022–23: coal, 9.6 exajoules (EJ); LNG, 4.5 EJ, from Australian Power Replace. This was multiplied by an emissions issue 90.2 for coal (MtCO₂-e/EJ) and 51.5 for LNG (MtCO₂-e/EJ), as drawn from the Australian Nationwide Greenhouse Accounts Elements
Exports for 2035 and 2050: this assumes a development aligned with the IEA’s Introduced Pledges State of affairs, as outlined within the World Power Outlook 2024. Observe the share modifications from 2023 to 2035 and 2050 for coal (-45% and -73% respectively) and for LNG (+9% and -47% respectively.) These figures don’t distinguish between steam coal for energy and metallurgical coal.
Correction: an earlier model of this text mentioned Australia was the world’s third-largest gasoline exporter. This wording has been amended to refer particularly to LNG, and to mirror that the order of the highest gas-exporting nations modifications from 12 months to 12 months.
