ESG and climate law in Australia has entered a decisive phase. Mandatory climate-related financial disclosures are now law, sustainability governance expectations are rising sharply, and regulators are actively enforcing greenwashing standards. For international businesses operating in or entering Australia, understanding the current legal landscape is not optional - it is a core compliance requirement. This guide covers the legislative framework, disclosure obligations, enforcement trends, governance expectations, and what businesses should be doing now to stay ahead of the curve.
Australia';s ESG regulatory architecture rests on several interlocking pieces of legislation and regulatory guidance. The most significant recent development is the Treasury Laws Amendment (Financial Market Infrastructure and Other Measures) Act, which introduced mandatory climate-related financial disclosures into the Corporations Act 2001 (Cth). This amendment creates a phased, entity-size-based disclosure regime administered by the Australian Securities and Investments Commission (ASIC) and aligned with the International Sustainability Standards Board (ISSB) framework.
The Corporations Act 2001 now requires certain entities to prepare annual sustainability reports as part of their statutory reporting obligations. These reports must address climate-related risks and opportunities using a structure modelled on IFRS S2 Climate-related Disclosures. The Australian Accounting Standards Board (AASB) has developed Australian Sustainability Reporting Standards (ASRS), specifically AASB S1 and AASB S2, which give domestic legal effect to the ISSB standards with targeted modifications for the Australian context.
Beyond climate disclosure, the broader ESG framework draws on the Australian Securities and Investments Commission Act 2001 (ASIC Act), which governs misleading conduct in financial services and underpins greenwashing enforcement. The National Greenhouse and Energy Reporting Act 2007 (NGER Act) continues to operate as the backbone of Australia';s greenhouse gas reporting system, requiring large emitters to report emissions, energy production and consumption data to the Clean Energy Regulator. These regimes are complementary but distinct, and businesses must navigate both simultaneously.
The Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) remains relevant for project-level environmental approvals, though reform discussions around nature-related disclosures are ongoing. Directors'; duties under the Corporations Act - specifically sections 180 to 184 - are increasingly interpreted by courts and regulators as encompassing climate-related financial risks, reinforcing the connection between ESG governance and legal liability.
The phased rollout of Australia';s mandatory climate disclosure regime is structured around three groups of entities, differentiated primarily by size thresholds measured by consolidated revenue, gross assets and employee headcount.
Group 1 entities - the largest listed and unlisted companies, financial institutions and superannuation funds - were the first required to prepare sustainability reports. These entities face the most comprehensive obligations, including full Scope 1, Scope 2 and Scope 3 greenhouse gas emissions disclosure, scenario analysis, and governance disclosures aligned with AASB S2.
Group 2 entities, which are mid-sized companies meeting lower size thresholds, are subject to a staggered commencement date that follows Group 1 by approximately one year. Group 3 entities, covering smaller but still significant companies, follow in a further subsequent phase. The phased approach reflects a deliberate policy choice to allow smaller entities time to build internal capability while ensuring the largest market participants lead the transition.
A non-obvious requirement that many foreign-owned Australian subsidiaries overlook is that the disclosure obligations apply at the Australian entity level, not merely at the global parent level. A multinational that reports under the EU';s Corporate Sustainability Reporting Directive (CSRD) or the SEC';s climate disclosure rules cannot simply rely on parent-level reporting to satisfy Australian obligations. Separate Australian sustainability reports, prepared in accordance with AASB S2, may be required.
The sustainability report must be lodged with ASIC through the Australian Securities and Investments Commission';s online portal and forms part of the annual report package. Directors must sign a directors'; declaration confirming the report complies with the applicable standards. During a transitional period, limited assurance over certain disclosures is required, with reasonable assurance phased in over subsequent years.
In practice, founders and CFOs of Group 2 and Group 3 entities often underestimate the lead time required to build data collection systems for Scope 3 emissions. Scope 3 covers indirect emissions across the value chain - supplier emissions, product use-phase emissions and end-of-life treatment - and gathering reliable data typically takes 12 to 18 months of preparation before the first report is due.
ASIC has made greenwashing enforcement a stated regulatory priority, and its track record now includes successful court proceedings, infringement notices and public warnings directed at fund managers, listed companies and financial product issuers. The legal basis for most greenwashing enforcement actions is the prohibition on misleading or deceptive conduct in financial services under the ASIC Act and the Corporations Act.
ASIC';s enforcement focus has centred on three categories of conduct. First, sustainability-related claims in product disclosure statements, target market determinations and marketing materials that are not supported by underlying investment mandates or portfolio holdings. Second, net-zero or carbon-neutral claims made without a credible, documented transition plan. Third, the use of ESG labels - such as "sustainable", "responsible" or "green" - without adequate definitional clarity or substantiation.
A common mistake made by international businesses entering Australia is assuming that ESG marketing language acceptable in their home jurisdiction will pass scrutiny here. Australian consumer protection law, enforced by both ASIC and the Australian Competition and Consumer Commission (ACCC), applies a rigorous standard: the overall impression conveyed by a communication, not merely its literal words, must be accurate and not misleading. Vague aspirational language about sustainability goals, unaccompanied by concrete metrics or timelines, carries real legal risk.
The ACCC has separately pursued greenwashing in consumer-facing markets, targeting product-level claims about environmental credentials. Its guidance on environmental and sustainability claims sets out a practical framework: claims should be specific, accurate, substantiated and not create a false overall impression. Businesses selling products or services in Australia with environmental claims - whether about packaging, carbon offsets or supply chain practices - should review their communications against this standard.
For investment managers, ASIC';s guidance on sustainable finance and ESG product labelling continues to evolve. The regulator has signalled interest in a formal labelling regime for sustainable investment products, which would impose defined criteria on funds using sustainability-related names. Businesses in the funds management sector should monitor ASIC consultation papers closely.

Australian corporate governance expectations around ESG have shifted materially in recent years. The Australian Securities Exchange (ASX) Corporate Governance Principles and Recommendations, now in their fourth edition, explicitly address environmental and social risks. Recommendation 7.4 calls on listed entities to disclose whether they have any material exposure to environmental or social risks and, if so, how they manage or intend to manage those risks.
Directors of Australian companies face personal exposure if they fail to give adequate consideration to climate-related financial risks. The landmark Abrahams v Commonwealth Bank of Australia case, while ultimately resolved without a final judgment on the merits, established that shareholder derivative actions on climate governance grounds are legally viable in Australia. Subsequent cases and regulatory guidance have reinforced that climate risk is a foreseeable financial risk that directors must consider when discharging their duty of care and diligence under section 180 of the Corporations Act.
In practice, this means boards should be able to demonstrate that climate risk has been identified, assessed and integrated into strategic planning and risk management frameworks. Board-level oversight of climate risk - whether through a dedicated board committee, a risk committee with explicit climate risk terms of reference, or regular board-level reporting - is increasingly expected by institutional investors and proxy advisers.
For superannuation funds, the Australian Prudential Regulation Authority (APRA) has issued Prudential Practice Guide CPG 229 on climate change financial risks. This guidance, while not legally binding in the same way as a prudential standard, sets out APRA';s expectations for how regulated entities should identify, assess, manage and disclose climate-related financial risks. APRA has made clear it will take supervisory action where entities fall materially short of these expectations.
Consider two practical scenarios. A large listed mining company must now prepare a full AASB S2-compliant sustainability report, conduct climate scenario analysis under at least 1.5°C and higher warming pathways, and disclose Scope 3 emissions from the combustion of sold products - often the largest component of its emissions profile. A mid-sized private equity-backed infrastructure business, by contrast, may fall into Group 2 or Group 3 and have more time to prepare, but should begin building data systems and governance structures immediately to avoid a compliance crunch.
Climate disclosure is the most immediate and well-defined ESG obligation in Australia, but nature and biodiversity-related requirements are developing rapidly. The Taskforce on Nature-related Financial Disclosures (TNFD) framework has attracted significant interest from Australian regulators and large corporates, and there are active policy discussions about whether nature-related disclosures should be incorporated into the mandatory sustainability reporting regime.
The EPBC Act is under review, with proposals for a new Nature Positive Plan that would strengthen environmental approval processes and introduce stronger biodiversity offset requirements. While legislative reform has moved slowly, businesses with significant land use, water use or biodiversity impacts - particularly in agriculture, mining, construction and infrastructure - should treat nature-related risk as an emerging compliance frontier rather than a distant concern.
Supply chain due diligence is another area of growing regulatory interest. Australia does not yet have a mandatory human rights due diligence law equivalent to the EU';s Corporate Sustainability Due Diligence Directive (CSDDD), but the Modern Slavery Act 2018 (Cth) requires entities with annual consolidated revenue above AUD 100 million to report annually on the risks of modern slavery in their operations and supply chains and the actions taken to address those risks. The Australian Border Force administers this regime, and the government has signalled interest in strengthening the Act to include mandatory due diligence obligations and penalties for non-compliance.
Businesses in sectors with complex global supply chains - retail, manufacturing, food and agriculture, technology - should treat modern slavery reporting as a live compliance obligation and invest in supply chain mapping and supplier engagement programmes. A common mistake is treating the modern slavery statement as a box-ticking exercise rather than a genuine risk management tool, which leaves businesses exposed both legally and reputationally.
Carbon markets and voluntary carbon offsets are also subject to increasing scrutiny. The Australian Carbon Credit Unit (ACCU) scheme, administered by the Clean Energy Regulator under the Carbon Credits (Carbon Farming Initiative) Act 2011, is the primary domestic carbon crediting mechanism. Businesses using ACCUs or international voluntary carbon credits to support net-zero or carbon-neutral claims must ensure the credits are genuine, additional and properly retired. ASIC and the ACCC have both signalled that offset-based claims are a priority area for scrutiny.
Building a credible ESG compliance programme in Australia requires a structured approach that addresses legal obligations, governance, data and disclosure simultaneously. The following areas demand priority attention.
First, determine which disclosure group your entity falls into under the phased mandatory climate disclosure regime. This requires a careful analysis of consolidated revenue, gross assets and employee numbers, taking into account the specific thresholds set by AASB S2 and the relevant commencement dates. Foreign-owned subsidiaries should also assess whether Australian-level reporting is required independently of parent-level reporting.
Second, establish a climate risk governance structure at board level. This means assigning clear responsibility for climate risk oversight, ensuring the board receives regular reporting on climate-related risks and opportunities, and documenting the board';s consideration of climate risk in strategic decisions. This documentation is not merely good practice - it is evidence of director diligence in the event of regulatory scrutiny or shareholder litigation.
Third, build the data infrastructure needed to support AASB S2 disclosures. Scope 1 and Scope 2 data is typically available from existing NGER Act reporting for large emitters, but Scope 3 data requires engagement with suppliers, customers and logistics providers. Many businesses find that a phased approach - starting with the most material Scope 3 categories - is more practical than attempting comprehensive coverage in the first reporting cycle.
Fourth, review all ESG-related marketing, product disclosure and investor communications against ASIC';s greenwashing guidance. Any claim that could be characterised as sustainability-related should be assessed for accuracy, substantiation and the overall impression it creates. This review should be repeated whenever new products are launched or existing communications are updated.
Fifth, prepare or update a climate transition plan. While transition plans are not yet legally mandated as standalone documents in Australia, they are expected by institutional investors, required by some lenders as part of sustainable finance arrangements, and increasingly treated by regulators as evidence of the seriousness of net-zero commitments. A credible transition plan sets out specific, time-bound actions, capital allocation decisions and governance accountability.

What is the difference between NGER Act reporting and the new mandatory climate disclosure regime?
The NGER Act requires large emitters to report greenhouse gas emissions, energy production and energy consumption data to the Clean Energy Regulator. It is primarily a data collection mechanism used to underpin government policy and the safeguard mechanism. The new mandatory climate disclosure regime under the Corporations Act, by contrast, requires entities to prepare investor-facing sustainability reports that address climate-related financial risks and opportunities, governance, strategy, risk management and metrics - including but not limited to emissions data. The two regimes overlap in their use of emissions data but serve different purposes and are administered by different regulators. Entities subject to both must comply with each separately, and NGER-reported data can be used as an input into sustainability reports but does not substitute for the broader AASB S2 disclosure requirements.
How long does it realistically take to prepare for mandatory climate disclosure, and what does it cost?
Preparation timelines vary significantly by entity size and existing data maturity. Large entities with established sustainability functions and existing NGER Act reporting obligations may need six to twelve months to build the additional systems and governance structures required for AASB S2 compliance. Mid-sized entities starting from a low base should allow twelve to eighteen months, particularly for Scope 3 data collection. Professional fees for advisory, legal and assurance services vary widely depending on the complexity of the business and the scope of work required. Costs typically span multiple service providers - sustainability consultants for data and strategy, legal advisers for governance and disclosure review, and auditors for assurance. Businesses should budget for ongoing annual costs as well as the initial setup investment, since the disclosure obligation is recurring.
Can a company rely on its global parent';s ESG reporting to satisfy Australian obligations?
Generally, no. Australian mandatory climate disclosure obligations apply at the Australian entity level, and a sustainability report prepared in accordance with AASB S2 must be lodged with ASIC as part of the Australian annual report. A parent-level report prepared under CSRD, SEC rules or another international framework does not automatically satisfy Australian requirements, even if it covers the Australian subsidiary';s operations. There may be some scope to incorporate parent-level information by reference or to use consolidated group data where the Australian entity is the ultimate parent, but foreign-owned subsidiaries should obtain specific legal advice on their obligations rather than assuming parent-level compliance is sufficient. The directors of the Australian entity bear personal responsibility for the directors'; declaration accompanying the sustainability report.
Australia';s ESG and climate law framework is now one of the most developed in the Asia-Pacific region, with mandatory disclosure obligations, active greenwashing enforcement and rising governance expectations creating a complex but navigable compliance environment. Businesses that invest early in data infrastructure, governance structures and legal review will be better positioned than those that treat ESG compliance as a future problem.
