The Real Cost of ASRS Compliance: What Australian Companies Are Actually Spending
Treasury estimated $750K-$1.6M per entity per year for ASRS compliance. We break down where that money actually goes, from data collection to consulting to assurance, and where most of it gets wasted.
The Australian Treasury's Policy Impact Analysis on climate-related financial disclosures estimated ongoing compliance costs of $1.0 to $1.3 million per entity per year. Edge Impact put the total bill for Australian companies at over $6.5 billion collectively. Those numbers keep getting repeated in board papers and consultant proposals. But nobody seems to break them down.
Where does the money actually go? And more importantly, how much of it is going to work that shouldn't cost that much?
We've been watching Group 1 entities file their first mandatory ASRS disclosures since early 2026. The spending patterns are becoming clear. Some costs are unavoidable. Some are inflated by bad process design. And a surprisingly large chunk is, bluntly, paying skilled professionals to do things a machine should be doing.
Here's the breakdown, based on Treasury's estimates and published analyses.
The seven places your ASRS budget disappears
Every company's situation is different. A construction company with 40 project sites has a fundamentally different cost profile to a financial services firm with two offices. But the categories are consistent, and the proportions are remarkably similar across industries.
Data collection and processing consumes, by our estimate, 40 to 50% of the total compliance cost for most entities. That's the single biggest line item, and it's the one most companies underestimate. A mid-size NGER reporter with 20 to 50 facilities typically needs 400 or more hours per year just to collect, clean, and process emissions data. We've broken down exactly where those 400 hours go before. At a loaded internal cost of $100 to $150 per hour (salary plus super plus overheads for a sustainability analyst or coordinator), that's $40,000 to $75,000 in internal labour. When companies outsource this work to consultants, the cost jumps to $80,000 to $150,000 because you're paying advisory rates for operational work.
Think about that. Half your compliance budget is spent getting data into a usable format. Not analysing it. Not making strategic decisions. Not writing disclosures. Just finding the electricity bill, reading the kWh, matching the emission factor, and typing it into a spreadsheet. Or paying someone $200 an hour to do that for you.
Consulting and advisory fees represent the second-largest cost. Advisory firms typically charge $150 to $250 per hour for mid-tier work and $250 to $400 per hour for specialist AASB S2 advisory from larger firms. A typical advisory engagement for ASRS disclosure preparation, covering climate risk assessment, materiality analysis, scenario analysis, governance narratives, and emissions calculations across Scope 1, 2 and 3, runs between $80,000 and $200,000 for a mid-market entity.
There's nothing wrong with paying for genuine advisory expertise. The problem is what that money often buys. More on that shortly.
Assurance fees under ASSA 5010 are a mandatory cost that didn't exist before. In Year 1, entities face limited assurance over governance disclosures, strategy (risks and opportunities), and Scope 1 and 2 emissions. The AUASB finalised ASSA 5010 in January 2025 and amended it in December 2025. For mid-market entities, limited assurance currently runs $30,000 to $80,000. For large entities with complex operations, assurance costs land between $100,000 and $300,000. When reasonable assurance kicks in from financial years beginning 1 July 2030, expect those numbers to roughly double.
One detail many companies miss: your financial statement auditor must also perform your sustainability assurance. You can't shop around. If your existing auditor is expensive, your sustainability assurance will be too.
That $30,000-$80,000 mid-market range assumes you secured an assurance provider on a reasonable timeline. For Group 2 entities now several weeks into their first mandatory reporting period, that assumption may not hold. Assurance capacity is tight, and an entity that engages late can face long lead times. A provider engaged late reviews your methodology after months of data collection is already behind them - so if they flag an emission factor error or a missed Scope 1 source, you're reworking data, not just paying a premium fee. That reworking cost doesn't show up in the assurance line item; it shows up back in data collection and processing, the category that was supposed to be finished.
There's also a live regulatory question hanging over the "roughly double" estimate for when reasonable assurance phases in from 2030. Treasury opened a public consultation in late August 2026, closing 2 October 2026, on efficiency-focused reforms to the ASRS framework - one of the specific items on the table is whether to ease or delay the escalation from limited to reasonable assurance. Nothing has changed yet, and the 2030 date in current law still stands. But if you're building a multi-year assurance cost forecast right now, treat that 2030 doubling as the current-law baseline, not a locked-in number - we cover the consultation's other two items, on core-concept guidance and Scope 3 supplier-data boundaries, in more detail here.
Internal team cost is often undercounted because it's "absorbed" into existing headcount. But it isn't free. A sustainability manager at $130,000 to $150,000 loaded cost will spend 30 to 50% of their time on ASRS compliance during reporting season. Finance team members reviewing climate-related financial impacts might contribute 200 hours. Legal reviewing liability statements, board declarations, and the modified liability provisions adds another 50 to 100 hours. We're honestly still working out how to quantify the executive time properly, but the hidden cost of pulling data entry work across departments is real and usually untracked.
Technology and software is ironically one of the smaller line items. Carbon accounting software typically costs between $20,000 and $100,000 per year depending on scale and capability. That's 5 to 10% of a typical compliance budget. Yet it's the line item that gets the most procurement scrutiny. CFOs will approve a $200,000 consulting engagement with a phone call but require three months of evaluation for a $40,000 software purchase. We understand why (it's a system, there's integration risk, there's lock-in concern), but the ratio of scrutiny to spend is inverted.
Scenario analysis is the cost that catches people off guard. AASB S2 requires climate-related scenario analysis across at least two temperature pathways. Doing this well, with scenarios localised to your actual operations, connected to financial line items, with documented assumptions, usually costs $30,000 to $80,000 when outsourced. Some Group 1 entities spent far more and still produced work that buckled under assurance because they used generic global scenarios instead of ones linked to their specific asset base and revenue mix.
Training and board education rounds out the budget. New frameworks mean new knowledge requirements. Board members need to understand what they're signing off on (the directors' declaration carries personal liability). Finance teams need to understand climate-related financial risks well enough to quantify them. Operations teams need to understand what data to collect and why. Budget $10,000 to $30,000 for the first year. Less in subsequent years, but it never drops to zero because the standards keep evolving.
Where most of the money gets wasted
Here's our actual thesis, and we know not everyone will agree with it: at least 30% of what companies spend on ASRS compliance in the first two years is going to work that either shouldn't be done manually or shouldn't be done twice.
The most obvious waste is paying advisory-rate consultants to do data entry. When a sustainability advisory engagement bills 500 hours and 350 of those hours are collecting utility bills, extracting consumption figures, matching emission factors, and building a spreadsheet model, that's not advisory. That's $70,000 to $105,000 in data processing at $200 to $300 per hour. The remaining 150 hours of genuine advisory work (disclosure drafting, materiality assessment, governance review) is the part worth paying for.
This isn't a criticism of consultants. They're responding to client demand. The company doesn't have its own data pipeline, so the consultant builds one as part of the engagement. Next year, the consultant builds another one because the first one wasn't designed to persist. Some sustainability consultants are looking for tools to automate the data processing so they can focus on the advice their clients actually need.
The second waste is running NGER and AASB S2 as separate processes. This happens more than it should. The NGER team files by 31 October using one set of calculations. The ASRS team prepares disclosures using a different methodology, sometimes different emission factors, sometimes different organisational boundaries. The same electricity bills get processed twice. The same fuel data gets extracted twice. The reconciliation between the two outputs consumes another 40 to 80 hours. We've explained how dual-framework reporting should work from a single data set and the answer is obvious in hindsight: one data pipeline, two reporting outputs. But surprisingly few companies have set it up that way yet.
The third waste is manual quality assurance that should be automated. Someone senior spends 40 hours reviewing a spreadsheet for errors, checking emission factor lookups, validating unit conversions, flagging consumption outliers. This is the kind of work that automated anomaly checks handle well, because rules never get tired at row 3,000 and they check every single entry, not a sample. Yet the manual review persists because "that's how we've always done it."
What the numbers look like when you fix the process
We're not going to claim software eliminates all ASRS compliance costs. It doesn't. You still need advisory input for scenario analysis, materiality, and disclosure drafting. You still need assurance. You still need internal team time for governance and strategy.
But the data collection and processing layer, that 40 to 50% of total cost, is where automation changes the equation most dramatically. Automated document processing handles utility bills, fuel dockets, waste reports, and invoices across multiple formats. As an illustration, if automated extraction removed 300 hours a year of manual handling, at $100 to $150 per hour loaded cost that would be $30,000 to $45,000 in internal labour. If you were paying consultants for that work, the figure would be roughly double.
Running NGER and AASB S2 from the same data pipeline eliminates duplication. Same source documents, same activity data, same emission factor library. One data entry process feeding two reports. (Carbonly writes AR5 GWP values, the set NGER uses. Any AASB S2 figure that needs AR6 values has to be recalculated.) That can remove much of the 40 to 80 hours of reconciliation work.
Automated quality checks catch errors before they become audit findings. Wrong unit conversions. Duplicate invoices. Consumption figures that fall outside expected ranges. Emission factors applied from the wrong year's NGA Factors workbook - the same state-based electricity and fuel factor lookups a reviewer would otherwise be checking row by row in a spreadsheet. When your assurance provider walks in and asks to trace a number back to its source document, the audit trail exists by default, not because someone spent a week building it retrospectively.
| Cost component | Typical manual cost (AUD) | With automated data pipeline (AUD) |
|---|---|---|
| Data collection and processing | $80,000 - $150,000 | $20,000 - $50,000 |
| Consulting (advisory only, not data entry) | $80,000 - $200,000 | $40,000 - $100,000 |
| Assurance (ASSA 5010 limited) | $30,000 - $80,000 | $25,000 - $65,000 |
| Internal team time | $50,000 - $100,000 | $30,000 - $60,000 |
| Software | $0 | $20,000 - $100,000 |
| Scenario analysis | $30,000 - $80,000 | $30,000 - $80,000 |
| Training | $10,000 - $30,000 | $10,000 - $30,000 |
| Total | $280,000 - $640,000 | $175,000 - $485,000 |
Those ranges reflect a mid-market entity with 20 to 50 sites. Larger entities will sit higher. Smaller ones lower. The savings aren't spectacular in percentage terms, roughly 25 to 30%, but in absolute dollars, $100,000 to $200,000 per year accumulates fast when you're looking at a decade of mandatory reporting.
The real benefit isn't just cost. It's time. When your sustainability manager gets 300 hours back, that's 300 hours available for decarbonisation strategy, supplier engagement, and the work that actually reduces emissions instead of counting them.
What this means for Group 2 and 3 companies
Group 2 entities (meeting two of: $200M revenue, $500M gross assets, 250+ employees) start reporting for financial years beginning 1 July 2026. Group 3 follows from 1 July 2027. The modified liability provisions under the Corporations Act limit private action over Scope 3 emissions, scenario analysis and transition plan statements until the end of 2027, but ASIC can still act.
The penalties mirror financial reporting: up to $15 million or 10% of annual turnover. Directors face personal liability for misleading statements. ASIC has said it'll take a "pragmatic and proportionate" approach during the phase-in, but in our reading that signals tolerance for good-faith attempts. It doesn't mean companies that didn't try will be ignored.
If you're a Group 2 entity with a standard 1 July-30 June financial year, your first reporting period isn't ahead of you anymore - it started 1 July 2026, and the early months of it suggest the same cost patterns Group 1 hit are repeating. If your financial year runs 1 January-31 December, your first period starts 1 January 2027 and you still have real runway. Either way, the question isn't whether you'll spend money on ASRS compliance. You will. The question is whether you'll spend it on data entry or on strategy.

Quick Answers
What does ASRS compliance actually cost per year? Treasury's own estimate is $1.0-$1.3 million per entity per year at the top end for large, complex reporters. For a mid-market entity with 20 to 50 sites, a more realistic manual-process range is $280,000-$640,000 once you break it down by data collection, advisory, assurance, internal time, software, scenario analysis and training.
Which single cost category is the biggest, and can it be reduced? Data collection and processing - 40 to 50% of the total budget for most entities. It's also the category with the most room to shrink, because most of that spend is manual bill-reading and emission-factor lookups, not genuine advisory judgement.
Do NGER and ASRS reporting have to cost double because they're separate frameworks? No, but running them as separate processes is a common and expensive mistake. The same electricity bills and fuel data get collected and reconciled twice, adding 40 to 80 hours of avoidable rework. One data pipeline feeding both outputs - with AR5 GWP values applied for NGER and AR6 for AASB S2 - removes that duplication.
Is ASRS compliance cheaper for Group 2 and Group 3 entities than it was for Group 1? Not automatically. The cost categories and per-hour rates are the same; what changes is how much of that spend goes to data entry versus strategy. Group 2 and 3 entities that set up an automated data pipeline before their first reporting period avoid the worst of what Group 1 entities paid consultants to do manually.
Why are assurance costs running higher than the quoted range for some Group 2 entities? Because the assurance market is capacity-constrained, not because ASSA 5010 itself changed. Entities that secured a provider early are paying close to the $30,000-$80,000 mid-market range. Entities still shopping for a provider months into their reporting period are facing longer engagement timelines and, often, rework costs when a late-arriving provider flags methodology issues after data collection is already underway.
Could the 2030 jump to reasonable assurance (and its cost) change? Possibly, but nothing has changed yet. Treasury's consultation, open until 2 October 2026, on ASRS framework reforms includes easing or delaying the limited-to-reasonable assurance escalation as one option under review. Current law still has reasonable assurance phasing in from financial years beginning 1 July 2030 - budget against that until an outcome is announced.
