# Australia NGER Scheme: Carbon Reporting Obligations for Manufacturers

Australia's National Greenhouse and Energy Reporting (NGER) scheme is the mandatory framework that captures emissions and energy data from the country's largest industrial operations — and the Safeguard Mechanism is tightening the screws on facilities above 100 kt CO2-e per year. This guide explains who must report, how to measure manufacturing emissions correctly, what the Safeguard Mechanism baseline means for your facility, and the penalties for getting it wrong.

## Key NGER concepts for manufacturers

### NGER Act 2007 — The Reporting Framework

The National Greenhouse and Energy Reporting Act 2007 created Australia's primary mandatory framework for measuring and reporting greenhouse gas emissions and energy production and consumption. The Clean Energy Regulator (CER) administers the scheme, collecting annual data from liable corporations and using it to inform national accounts and climate policy. Reporting is structured at two levels: the corporate group threshold (triggering registration and group-level reporting) and the facility threshold (triggering facility-level disclosure). All reported data is published on the CER's NGERS public register, making emissions performance visible to investors, customers, and civil society.

### Reporting Thresholds — Who Must Register

A controlling corporation must register with the CER if its corporate group exceeds either 25,000 tonnes CO2-equivalent (kt CO2-e) of greenhouse gas emissions or 100 terajoules (TJ) of energy production or consumption in a financial year. At the facility level, individual facilities that emit 10 kt CO2-e or consume 100 TJ trigger facility-level reporting requirements. For manufacturers, both process emissions (chemical reactions in production, e.g. calcination in cement) and combustion emissions from on-site energy use count toward these thresholds. The manufacturing sector accounts for approximately 35% of Australia's industrial energy consumption — threshold exceedance is common for mid-to-large scale operations.

### NGER Measurement Determinations

The NGER (Measurement) Determination, made under the NGER Act, prescribes the exact methods manufacturers must use to quantify each emissions source. It covers Scope 1 emissions (direct — combustion, process, fugitive), Scope 2 emissions (purchased electricity and heat), and energy consumption. Methods range from direct measurement using calibrated meters to default emission factors published by the CER. Manufacturers must select the appropriate method for each source and document their methodology in an emissions measurement plan. The Determination is updated periodically — using an outdated method is a compliance breach even if the error is unintentional.

### Safeguard Mechanism — Large Emitter Obligations

Facilities emitting 100 kt CO2-e or more per year are subject to the Safeguard Mechanism, a regulatory baseline that caps net emissions from Australia's largest emitters. From 1 July 2023, Safeguard baselines decline at 4.9% per year on average, tracking toward net zero by 2050. Facilities that exceed their baseline must surrender Australian Carbon Credit Units (ACCUs) or Safeguard Mechanism Credits (SMCs) to cover the excess. The trajectory makes early emissions reduction investment significantly cheaper than waiting — each year of delay means purchasing more expensive offsets against a tighter baseline.

### Australian Carbon Credit Units (ACCUs)

ACCUs are the compliance currency of Australia's carbon markets, issued by the CER for emissions avoidance or removal projects registered under the Emissions Reduction Fund (ERF). In 2024, ACCU spot prices traded in the range of AUD $30 to $60 per tonne, though forward prices reflect expectations of tightening Safeguard baselines and growing demand. Manufacturers subject to the Safeguard Mechanism can surrender ACCUs to offset above-baseline emissions, or they can sell surplus SMCs if they outperform their baseline. Buying ACCUs in advance (forward contracting) is increasingly used to hedge against future price increases.

### Penalties for NGER Non-Compliance

Failure to register when required, late lodgement of annual reports, or providing false or misleading information in a report all carry civil penalties under the NGER Act. Late reporting attracts a penalty of AUD $13,320 per day while the breach continues. Providing false or misleading information is a criminal offence with potential imprisonment for individuals and substantial fines for corporations. The CER also has powers to conduct audits, issue compliance notices, and publish details of enforcement actions — reputational exposure that increasingly matters to institutional investors applying ESG screening criteria.

## NGER compliance process for manufacturers

01

Calculate your corporate group's total greenhouse gas emissions and energy consumption for the most recent financial year. Include all Scope 1 emissions (combustion, process, fugitive) and Scope 2 emissions (purchased electricity and heat) across all facilities controlled by the group. Use the NGER (Measurement) Determination methods appropriate to each emissions source.

02

Determine whether your corporate group exceeds NGER Act registration thresholds — 25 kt CO2-e or 100 TJ of energy. If either threshold is met, registration with the Clean Energy Regulator is mandatory before the end of the reporting year. Registration is completed through the NGERS online portal at ngers.cleanenergyregulator.gov.au.

03

Register with the Clean Energy Regulator via the NGERS online system. The registration form requires details of all facilities within scope, the nominated group contact, and confirmation that the controlling corporation has been identified correctly under the NGER Act's corporate group rules. Registration must be completed by 31 August following the first threshold year.

04

Establish and document your measurement procedures for each facility and emissions source. Your emissions measurement plan should identify each source, the applicable NGER Determination method, the data collection process, and quality assurance procedures. Engage a qualified greenhouse gas consultant if your process emissions are complex or if you are using facility-specific emission factors.

05

Collect facility-level data on energy consumption, production volumes, and emissions for the full financial year (1 July to 30 June). Implement data quality controls — meter readings, fuel invoices, and production logs should be reconciled monthly rather than reconstructed at year-end. Data gaps are a common audit finding and can trigger CER information-gathering notices.

06

Submit your annual NGER report through the NGERS online portal by 31 October each year. The report must include facility-level emissions and energy data, the measurement methods used, and scope of operational control. Large reporters (above 500 kt CO2-e) are required to have their report verified by a registered greenhouse and energy auditor before lodgement.

07

Review your Safeguard Mechanism baseline if any facility emits 100 kt CO2-e or more. Assess whether your facility is on track to meet its declining baseline trajectory and model the cost of ACCU surrender versus abatement investment. Engage with the CER early if you anticipate a baseline exceedance — the CER has a Safeguard Mechanism crediting and flexibility mechanism that allows some carry-forward and multi-year averaging.

## Frequently asked questions

### Who must report under the NGER scheme?

Any Australian controlling corporation whose corporate group emits 25 kt CO2-e or more of greenhouse gases, or produces or consumes 100 TJ or more of energy, in a financial year must register and report under the NGER Act 2007. At the facility level, individual facilities meeting 10 kt CO2-e or 100 TJ thresholds must be reported separately. Foreign-controlled Australian entities may also be in scope — the NGER Act's corporate group rules can be complex for multinational structures, and legal advice is recommended if group boundaries are unclear.

### What is the Safeguard Mechanism and does it apply to my facility?

The Safeguard Mechanism sets an emissions baseline for Australia's largest industrial facilities — those emitting 100 kt CO2-e or more per year. From 1 July 2023, these baselines decline at approximately 4.9% per year, tracking toward net zero by 2050. Facilities that emit above their baseline must surrender ACCUs or Safeguard Mechanism Credits to cover the excess. If your facility crosses the 100 kt CO2-e threshold for the first time, you will receive a default baseline from the CER — you should review it carefully and apply for a revised baseline if your production volumes or methods make the default inappropriate.

### How are manufacturing process emissions measured under NGER?

Process emissions — emissions from chemical reactions rather than combustion — are measured using methods specified in the NGER (Measurement) Determination. Common manufacturing process emissions include CO2 from calcination (cement, lime), fugitive emissions from refrigerants, and N2O from chemical production. The Determination prescribes default emission factors for many processes, but manufacturers with significant process emissions may be required or permitted to use facility-specific factors derived from direct measurement, which can improve accuracy and reduce compliance risk.

### What penalties apply for late or incorrect NGER reporting?

Late lodgement of an annual NGER report attracts civil penalties of AUD $13,320 per day while the breach continues. Failing to register when required, and providing false or misleading information in a report, are separate offences with their own penalty scales — the latter can be a criminal offence for individuals. The Clean Energy Regulator also has the power to conduct compliance audits and publish enforcement actions, creating reputational exposure that is increasingly material for listed companies and businesses with institutional investors applying ESG frameworks.
