215 facilities. That’s roughly how many industrial sites now sit under the Safeguard Mechanism’s baseline-and-credit system, covering a bit under a third of Australia’s total emissions from a list that reads like a who’s who of steel, alumina, LNG and cement. Every one of them is now required to cut emissions intensity by 4.9 per cent a year through to 2030, a ratchet that tightens whether the facility is a gas plant in the Pilbara or a smelter clinging on in regional Victoria. The scheme has been running in its reformed form since mid-2023. Three-plus years in, the argument about who’s actually carrying the cost has stopped being theoretical.
Start with the mechanism itself, because most of the public commentary skips the mechanics and goes straight to the politics. The Clean Energy Regulator sets a baseline for each covered facility, based on historical emissions intensity and adjusted for production. If a facility emits below its baseline, it generates Safeguard Mechanism Credits it can sell. If it emits above, it has to buy credits or Australian Carbon Credit Units to cover the gap. The baselines decline each year on that near-5-per-cent trajectory. It’s a cap-and-trade system dressed in intensity clothing, and the dressing matters because intensity baselines reward efficiency gains even while absolute output, and sometimes absolute emissions, keeps climbing.
Who is actually covered, and who isn’t
The scheme catches any facility emitting more than 100,000 tonnes of CO2-equivalent a year. That threshold sweeps in LNG trains, steelworks, aluminium smelters, cement kilns, some larger gas processing plants and a handful of coal mines on fugitive emissions grounds. It does not catch the much larger, much more diffuse tail of emissions from transport, agriculture and the grid itself, which run through entirely separate policy levers. That’s a point worth sitting with. Safeguard is an industrial-facility policy, not an economy-wide carbon price, and treating it as a stand-in for the latter is where a lot of the public debate goes sideways.
The Clean Energy Regulator publishes facility-level data every year, and the pattern since the 2023 reform has been fairly consistent: LNG and resources facilities dominate the credit-buying side, while a smaller number of generators and legacy industrial sites generate surplus credits. The regulator’s own Safeguard data explorer, published on cleanenergyregulator.gov.au, is the primary source here, and it’s more interesting reading than most government portals have any right to be.
The trade exposure problem nobody fully solved
Here’s where the policy gets genuinely hard. Steel, alumina, cement and some chemicals producers compete against imports from countries with no carbon price at all, or one so weak it’s effectively decorative. Push baselines down too fast on an exposed facility and you don’t cut global emissions, you just shift production offshore to a dirtier competitor and call it a win on the domestic ledger. The Australian Government built in protections for genuinely trade-exposed facilities, with slower decline rates and access to the Safeguard Transformation Stream, which offers co-funding support through programmes administered with ARENA and the CEFC for facilities investing in decarbonisation.
Whether that’s enough is the live argument. The Australian Aluminium Council and the Australian Steel Institute have both, at various points over the past two years, flagged concern that the baseline trajectory outpaces the realistic technology path for their sectors. There’s no commercial pathway yet to decarbonise primary aluminium smelting at the pace the baselines imply, not without either enormous firmed renewable supply or a technology that doesn’t exist at scale.
I’d push back a little on the framing that gets used in most of the coverage of this, which tends to present it as heavy industry versus the climate target, full stop. The sharper read is that it’s heavy industry versus a baseline schedule set assuming decarbonisation options (cheap firmed power, green hydrogen reduction routes, electrified kilns) arrive faster than they plausibly will. That’s a scheduling problem as much as an ambition problem, and the two get conflated constantly in the public debate.
Where the gas sector sits in this
LNG facilities are some of the largest single emitters under Safeguard, and the gas sector’s response has mostly been to buy credits rather than cut processing intensity, because there’s genuinely not much room to cut emissions from liquefaction without changing the gas composition itself. Santos’s Moomba and Narrabri operations, which we’ve covered in detail in our profile of Santos at the centre of the east-coast gas standoff, sit partly inside this framework, with the Moomba carbon capture project doing double duty as both a genuine abatement project and a reputational asset in Safeguard compliance terms. That’s not cynicism on Santos’s part, it’s rational behaviour inside the rules as written. The honest observation is that CCS at Moomba works for Safeguard purposes regardless of whether you think CCS is the right long-term answer for the broader gas question, which we’ve examined separately in our piece on Will Snowy 2.0 ever earn its keep – different topic, same underlying tension between policy timelines and project timelines.
A credit market that’s thinner than advertised
The Safeguard Mechanism Credit market has been talked up as a genuine price signal, a domestic version of the EU’s emissions trading scheme in miniature. In practice, trading volumes have been modest and the market remains shallow, dominated by a small number of large buyers and sellers, which means price discovery is noisier than the headline carbon price figures suggest. A thin market is still a market, and it still moves incentives at the margin. But anyone citing a single Safeguard credit price as evidence of a settled, liquid carbon price in Australia is overstating what the data actually shows. The Clean Energy Regulator’s quarterly carbon market reports are the place to check this rather than taking a broker’s quoted figure at face value.
Who’s really carrying the cost
We’ve written before, in our earlier piece on the Safeguard Mechanism and who’s really carrying the cost, that the burden doesn’t fall evenly, and nothing in the past year has changed that conclusion. Facilities with cheap access to firmed renewable power, or with process emissions that are genuinely easy to abate, are coming out ahead and generating saleable credits. Facilities tied to processes with no mature low-carbon substitute, think primary aluminium, integrated steelmaking, some cement kilns, are absorbing a compliance cost that functions as a tax on staying in business as currently configured. That’s not a flaw in the policy logic. Intensity-based schemes are supposed to reward the switchers and penalise the holdouts. But it does mean some of Australia’s largest regional employers are facing a genuine structural cost they can’t fully pass through to export customers, because those customers can source the same commodity from a jurisdiction with no equivalent carbon cost at all.
This is where I’ll register the mildly unfashionable view. A lot of climate commentary treats any industry complaint about Safeguard costs as special pleading, dismissible on the grounds that polluters always complain about carbon policy. Sometimes that’s fair. But the aluminium and steel cases are different in kind from, say, a coal generator complaining about closure timelines, because there’s a real risk of carbon leakage rather than just a transfer of cost onto shareholders. If Portland or Tomago can’t get a commercially viable path to lower-carbon primary aluminium production by the early 2030s, and the baseline keeps tightening regardless, the facility doesn’t decarbonise, it closes, and the aluminium gets made somewhere with a dirtier grid and no carbon price at all. Global emissions go up. That’s a genuinely bad outcome dressed up as a domestic policy win, and I don’t think the current settings have fully reckoned with it.
The firmed power bottleneck underneath it all
Strip away the carbon accounting and most of the Safeguard compliance problem for heavy industry comes back to the same bottleneck we keep writing about on this site: there isn’t enough firmed, dispatchable renewable capacity in the right places yet to let energy-intensive manufacturers electrify at the scale and reliability they need. That’s the argument running through our pieces on gas peakers versus big batteries and on what firming actually means. A smelter needs power 24 hours a day, every day, at a price it can plan five years out against, and the current build-out of renewable energy zones, transmission and storage is not yet delivering that combination at the volume heavy industry needs. AEMO’s Integrated System Plan, covered in our explainer on what the Integrated System Plan actually says, lays out a credible long-run pathway. Credible long-run pathways don’t help a smelter facing a compliance obligation this financial year.
Where this actually lands
The government’s own review settings allow baselines and trajectories to be adjusted, and there’s a reasonable chance some trade-exposed sectors get further relief before 2030 rather than the schedule holding exactly as legislated. That’s not a prediction of weakness in the policy, it’s a reasonable reading of how every carbon scheme in a jurisdiction with trade-exposed heavy industry has eventually had to bend, the EU included. The Department of Climate Change, Energy, the Environment and Water runs the formal consultation process on these settings, and it’s worth tracking directly through dcceew.gov.au rather than through secondhand industry press releases, which tend to run hot in both directions.
The scheme is doing roughly what it was designed to do: it’s pushing covered facilities toward lower emissions intensity, generating a real if thin price signal, and exposing which sectors have a genuine low-carbon pathway and which don’t yet. What it hasn’t solved, and probably can’t solve on its own, is the mismatch between a legislated annual ratchet and the much messier, much slower reality of building firmed power at industrial scale in regional Australia. Whether that gap closes through faster transmission builds, further baseline relief, or a few high-profile closures that nobody wants to put their name to, is the thing to watch over the next two Safeguard compliance cycles.
