NGER reporting is Australia's mandatory annual report of greenhouse gas emissions, energy production and energy consumption, lodged with the Clean Energy Regulator. A corporate group must report once it meets a threshold: 50 kt CO₂-e or 200 TJ of energy at group level, or 25 kt CO₂-e or 100 TJ at one facility. Reports are usually due by 31 October.
NGER reporting software should help collect invoices and meter data, apply the factors and methods required for the reporting year, consolidate facility data, retain an audit trail and prepare outputs for EERS. The reporter remains responsible for checking that the submission is complete and accurate. This guide explains what to assess when choosing software for that workflow.
The NGER scheme requires controlling corporations that meet defined thresholds to report greenhouse gas emissions, energy consumption, and energy production across every facility they operate [1]. In the 2024–25 reporting year, 978 corporations reported a combined 296.6 million tonnes of CO₂-equivalent direct emissions and consumed 3,580.5 petajoules of energy [2]. These are not small numbers, and the reporting requirements that underpin them are not straightforward.
Yet many organisations still manage their NGER compliance through spreadsheets, manual data collection, and last-minute consolidation. The result is predictable: months of effort, recurring data quality issues, audit findings, and the ever-present risk of late or inaccurate submissions.
There is a better approach. Purpose-built NGER reporting software automates the data pipeline from energy invoices and meter reads through to emissions calculations and outputs prepared for review and EERS submission, turning what was a quarterly fire drill into a continuous, auditable process.
What the NGER scheme requires
Before evaluating software, it is worth understanding exactly what the scheme demands.
The NGER scheme operates under the National Greenhouse and Energy Reporting Act 2007 and is administered by the Clean Energy Regulator. Corporations must register and report if they meet either the facility-level threshold (25,000 tonnes CO₂-e or 100 terajoules of energy) or the corporate-level threshold (50,000 tonnes CO₂-e or 200 terajoules) [1].
Reporting follows facilities and corporate-group boundaries defined by the scheme. Operational control is central to deciding who reports a facility. Ownership, billing accounts and site addresses alone don't establish the reporting boundary.
Who registers. The obligation sits with the controlling corporation, defined as a constitutional corporation with no Australian incorporated holding company. That is the top Australian entity in the group, not each operating subsidiary.
When to register. Applications are due by 31 August following the financial year in which a threshold was met. Missing that date contravenes the NGER Act and can attract civil penalties, and finding a triggered year after the fact does not remove the obligation to register and report.
Energy use can trigger registration even without substantial on-site fuel combustion. 100 terajoules is about 27.8 GWh of electricity. Check facility boundaries and corporate-group totals before deciding whether a portfolio meets a threshold.
Reporting covers three core areas: Scope 1 (direct) emissions from sources owned or controlled by the corporation, Scope 2 (indirect) emissions from purchased electricity and heat, and energy consumption and production across all facilities. Reports must be submitted through the Emissions and Energy Reporting System (EERS) normally by 31 October each year, covering the preceding financial year (1 July to 30 June). For the 2025–26 reporting year, the deadline is midnight (AEDT) Monday 2 November 2026 [9].
For Scope 2 emissions, the 2023–24 reporting year introduced a voluntary market-based method alongside mandatory location-based reporting. The market-based approach allows corporations to reflect their renewable energy purchases, including surrendered Large-scale Generation Certificates (LGCs), in their reported emissions [3]. From the 2025–26 reporting year onward, corporations that elect the market-based method must apply it consistently across all facilities within their group [4].
The scheme also intersects with the Safeguard Mechanism for high-emitting facilities and, increasingly, with climate-related financial disclosures under the Treasury Laws Amendment (Financial Market Infrastructure and Other Measures) Act 2024. Group 2 sustainability reporting applies to annual reporting periods beginning on or after 1 July 2026. An entity must be required to prepare an annual financial report under Chapter 2M of the Corporations Act and meet an applicable sustainability reporting threshold; NGER status alone does not establish coverage. Check ASIC's sustainability reporting guidance.
In short: the scope is broad, the methodology is prescribed, the deadlines are firm, and the regulatory interconnections are growing.
How does the NGER reporting year work?
Plan around the reporting year and the applicable registration and lodgement deadlines.
1 July to 30 June. The reporting year is the Australian financial year. Data has to be attributed to the right year and the right facility, including where operational control transferred partway through.
31 August. Registration applications are due for a group that triggered a threshold in the year just ended.
Annual report. Lodge through the Emissions and Energy Reporting System. The usual date is 31 October, adjusted to the next business day when applicable. For 2025–26, the confirmed deadline is midnight AEDT on Monday 2 November 2026.
Publication. The Clean Energy Regulator publishes specified emissions and energy data under the scheme. Public disclosure thresholds and reporting requirements are distinct, so not every item submitted is necessarily published.
Reports are auditable. Keep records that substantiate the reported activities, calculations and methods for five years from the end of the relevant reporting year. The Clean Energy Regulator can require an audit by a registered greenhouse and energy auditor. CER recordkeeping requirements
How is NGER different from ASRS, the Safeguard Mechanism, and NABERS?
NGER is the measurement layer several other regimes sit on top of. The distinctions matter because the obligations stay separate even when the underlying data is shared.
NGER vs sustainability reporting. NGER is a regulatory submission to the Clean Energy Regulator. Mandatory climate-related sustainability reporting under the Corporations Act and AASB S2 has a separate scope and phased assurance requirements. NGER status is relevant to coverage, but an entity must also be required to prepare an annual financial report under Chapter 2M and meet the applicable section 292A threshold. Shared data can support both obligations, but each has its own reporting requirements. ASIC sustainability-reporting scope
NGER vs the Safeguard Mechanism. Safeguard generally applies to facilities with more than 100,000 tonnes of covered Scope 1 CO2-e emissions annually. Covered emissions have specific exclusions. Safeguard adds baseline and compliance obligations for covered facilities, while NGER supplies the reporting framework. Safeguard coverage
NGER vs NABERS. NABERS rates one building's measured performance against comparable stock, and is voluntary in most situations. NGER counts absolute emissions and energy across a corporate group because the law requires it. Different unit, different purpose, drawn from the same meter and invoice data.
Why spreadsheets break down for NGER
Spreadsheets served a purpose when NGER was simpler and portfolios were smaller. For organisations with a handful of facilities and straightforward emission sources, a well-structured spreadsheet could handle the calculations.
That era is over.
Modern NGER obligations require collecting energy data from dozens or hundreds of meters, across multiple utility types and billing periods. Each data point must be matched to the correct facility, the correct emission source category, and the correct measurement determination method. Emission factors update annually, and the methodology rules themselves evolve, as demonstrated by the 2025–26 amendments introducing market-based biomethane and hydrogen reporting and new fugitive emissions requirements [4].
Spreadsheet-based reporting introduces risk at every stage. Data is manually entered from invoices, creating transcription errors. Emission factor updates require manual changes across multiple cells, with no built-in version control. Consolidation across facilities depends on copy-paste workflows that break when formats change. And audit trails are, at best, informal notes rather than systematic records of every data point and calculation.
The Clean Energy Regulator has made its position clear: compliance and enforcement are priorities, with repeated inaccuracies or failures to report on time triggering enforcement action [6]. The Regulator now publishes the details of late reporters, adding reputational risk to the financial and legal consequences of non-compliance.
For organisations with material energy portfolios, the question is no longer whether to automate NGER reporting, but how.
What NGER reporting software should do
Not all software marketed for NGER compliance is equal. The right platform should address the entire reporting workflow, not just the final calculation step. Here is what that looks like in practice.
Automated data collection
The foundation of accurate NGER reporting is reliable data. Software should automatically ingest energy data from invoices (via OCR or EDI), meter data feeds, and utility retailer portals. Manual data entry should be the exception, not the rule.
For organisations managing multiple utility types, including electricity, natural gas, water and LPG, the platform must handle every commodity in a single system. Fragmenting data across utility-specific tools creates the same consolidation problems as spreadsheets.
Emission factor management
NGER emission factors are published annually by the Clean Energy Regulator and vary by fuel type, state, and calculation method. Software must maintain a current, auditable library of all applicable emission factors and apply the correct factor automatically based on the facility's location, fuel type, and reporting year.
This includes supporting both location-based and market-based Scope 2 calculation methods, with the ability to manage renewable energy certificate data for market-based reporting.
Facility-level and corporate-level aggregation
NGER reports require data at both the facility level and the corporate group level. Software must maintain the facility hierarchy, handle transfers of operational control during the reporting year, and aggregate emissions and energy data correctly across the group structure.
This is where many generic sustainability tools fall short. NGER has specific rules for operational control, group structures, and threshold calculations that differ from voluntary reporting frameworks like the GHG Protocol.
Audit trail and evidence management
Every data point in an NGER report should be traceable back to its source: the original invoice, meter read, or manual entry. Software must keep a complete audit trail that gives internal and external auditors traceable evidence from source to calculation.
Registered NGER auditors will test the completeness, accuracy, and methodology compliance of reported data. A system with built-in audit trails dramatically reduces the cost and duration of these assurance processes.
Outputs prepared for review and lodgement
The final output must align with the EERS submission format. Software should generate reports that can be uploaded directly or that map cleanly to the Regulator's data templates, eliminating the manual formatting step that introduces errors in the final mile.
The hidden cost of manual NGER compliance
The direct cost of manual NGER reporting is the time your team spends collecting, cleaning, calculating, and formatting data. For a mid-size corporation with 20 to 50 facilities, this typically absorbs two to four full-time equivalent months of effort annually, concentrated in the August-to-October reporting window [7].
But the indirect costs are often larger.
Late or inaccurate NGER reports can trigger enforcement action from the Clean Energy Regulator, including infringement notices and civil penalties under the NGER Act [1]. For facilities covered by the Safeguard Mechanism, data errors can directly affect baseline calculations and offset obligations, with material financial consequences.
Poor data quality in NGER submissions also cascades into climate-related financial disclosures. As mandatory climate reporting expands under the Treasury Laws Amendment Act, the emissions data underpinning your NGER report will feed directly into your annual report and financial statements. Errors that were once confined to a regulatory submission now have board-level visibility.
And for energy consultants managing NGER compliance on behalf of clients, the reputational cost of a late or inaccurate submission is significant. Clients expect their advisors to deliver compliant reports, on time, every time. Manual processes make that promise increasingly difficult to keep.
How Utilified automates NGER data
Utilified's Utility Management System (UMS) addresses the data foundation that NGER reporting depends on. Rather than treating emissions reporting as a standalone exercise, UMS integrates it into the continuous management of your energy portfolio.
Where the ESG module is enabled, UMS collects and validates energy data from invoices, meter reads and supported retailer feeds for electricity, natural gas, water and LPG, and supports NGER report preparation. Every data point is matched to the correct site, meter, and billing period, creating a single source of truth for your entire energy portfolio.
For Scope 2 emissions, UMS supports both location-based and market-based calculation methods, applying the correct state-based emission factors and accounting for renewable energy certificate surrenders. The dual-method capability means organisations can report under both approaches from the same dataset, without maintaining parallel spreadsheets.
The platform maintains a complete audit trail from source document to calculated emission, giving your compliance team and external auditors full traceability. And because the data flows continuously rather than in a last-minute batch, your NGER position is visible year-round, not just in the weeks before the October deadline.
For energy consultants, UMS scales this capability across every client portfolio. One platform, one data model, every client's NGER data managed to the same standard.

What changes in 2025–26 and beyond
The NGER scheme is not standing still. Reports for the 2025–26 reporting year are due by midnight AEDT on Monday 2 November 2026, because 31 October falls on a Saturday this year, and the Clean Energy Regulator has said no extensions can be granted [9]. They're also the first reports prepared under several material changes [4].
Market-based reporting now extends to biomethane and hydrogen consumption emissions, broadening the scope of fuel types that require certificate-based accounting. New requirements for reporting flared gas quantities apply when Methods 2, 2A, or 3 are used for fugitive emissions from natural gas operations. And the market-based method for Scope 2 electricity emissions now requires consistent application across all facilities in a corporate group, removing the ability to cherry-pick the method by facility.
Location-based electricity emission factors were updated for 2025–26. Use the factors and methods in the NGER Measurement Determination applicable to that reporting year; do not automatically carry forward an earlier year's factors or apply newer 2026–27 changes [3]. For thresholds and deadlines, see our guide to what NGER reporting is.
Looking further ahead, the Australian Government's response to the Climate Change Authority's NGER review signals mandatory agricultural emissions reporting by 2026–27 and land sector emissions by 2027–28 [8]. The scope of what must be reported is expanding, not contracting.
For organisations still relying on manual processes, each expansion adds another layer of complexity to an already strained workflow. An automated data pipeline makes those changes easier to absorb.
Getting started
If your organisation reports under NGER and you are still relying on spreadsheets or disconnected tools, the business case for automation is straightforward. Calculate the hours your team currently spends on data collection, emission calculations, and report preparation. Factor in the cost of data errors, audit remediation, and compliance risk. Then compare that against a platform that handles the data pipeline continuously and prepares outputs for your team to review and lodge.
The transition does not need to happen all at once. Start by centralising your energy data in a single platform. Once your invoices, meter reads, and site data are flowing automatically, the emissions calculations and reporting outputs follow naturally.
Utilified brings electricity, gas, water and LPG into one system, validates your data continuously, and prepares NGER report data for your compliance team to review and lodge in EERS. Your team remains responsible for methodology, review and lodgement, and UMS doesn't provide accredited assurance. Less of the October scramble, and less spreadsheet risk.

Frequently asked questions
When are NGER reports due for 2025–26?
By midnight AEDT on Monday 2 November 2026. The usual date is 31 October, but it falls on a Saturday this year, so the next-business-day rule applies. The Clean Energy Regulator has said no extensions can be granted.
Who has to report under NGER?
A controlling corporation must register when its group meets an NGER threshold. At facility level, the tests are 25,000 tonnes CO₂-e or more of combined Scope 1 and Scope 2 emissions, 100 TJ or more of energy produced, or 100 TJ or more consumed. At corporate-group level, the corresponding thresholds are 50,000 tonnes CO₂-e, 200 TJ produced, or 200 TJ consumed. If only facility thresholds are met, reporting covers those facilities. See the Clean Energy Regulator's guidance on assessing your obligations [10].
Can I use the market-based method for Scope 2 under NGER?
Yes. Voluntary market-based Scope 2 reporting has been available since 2023–24, alongside mandatory location-based reporting. It can reflect eligible renewable electricity purchases and certificate surrenders. From 2025–26, a group choosing the market-based method must apply it consistently across all facilities [3].
Do NGER reports have to be audited?
Not every NGER report requires an audit. The Clean Energy Regulator uses a targeted audit program and may select your report for audit. Keep supporting records for five years from the end of the reporting year in which the recorded activities occurred. Traceable invoices, meter reads, calculations and methods help you respond to an audit [11].
What should NGER reporting software automate?
Software should support the data pipeline: collecting invoices and meter data, applying the factors and methods required for the reporting year, consolidating facility data, retaining an audit trail, and preparing outputs for EERS. Automation supports reporting; the reporter remains responsible for checking that the submission is complete and accurate.
Is NGER reporting mandatory?
Registration and reporting are mandatory when the relevant NGER requirements apply. Check the registration thresholds, reporting scope and any separate obligations, including Safeguard, rather than assuming one threshold test resolves every obligation.
Does NGER cover Scope 3 emissions?
NGER does not require Scope 3 emissions reporting. Separate sustainability-reporting obligations may require Scope 3 disclosures, with transitional relief under the applicable standard. Check those requirements independently.
What is the difference between NGER and ASRS reporting?
NGER reports emissions and energy to the Clean Energy Regulator. Mandatory sustainability reporting under the Corporations Act and AASB S2 covers climate-related financial information. NGER registration is relevant to its thresholds, but coverage also depends on Chapter 2M and the applicable statutory tests.
