ESG reporting in Australia is the process of disclosing environmental, social, and governance performance data to the public. It covers emissions, workforce practices, board oversight, and climate risk in one report.
Australian businesses prepare ESG reports by collecting data across operations, applying standards such as AASB S1, AASB S2, and GRI, and publishing results alongside financial statements.
From FY2025, mandatory climate disclosures apply to the largest Australian companies. Therefore, this blog will cover all ESG reporting obligations, frameworks, and data requirements that are vital to understand.
Key Takeaways
ESG reporting is the structured disclosure of environmental, social, and governance performance data in a format that is measurable, comparable, and audit-ready for investors and regulators.
AASB S2 introduces mandatory ESG reporting across three phased groups from FY2025 to FY2027, based on revenue, asset, and headcount thresholds.
Starting ESG reporting follows a six-stage process covering obligation assessment, materiality, framework selection, data collection, report drafting, and assurance.
Best practices involves using a centralised ESG software integrated with ERP and HR systems, applies emission factors, and produces assurance-ready audit trails across reporting cycles.
What Is ESG Reporting?
ESG reporting is the disclosure of a company’s environmental, social, and governance performance. It translates sustainability activities into measurable data that stakeholders can use for decisions.
The environmental pillar covers emissions, energy, water, and waste. The social pillar covers workforce, safety, and community impact. The governance pillar covers board structure, ethics, executive pay, and risks.
In Australia, ESG reporting has shifted from voluntary communication to regulated disclosures. All companies must prepare climate statements under AASB S2, with phased thresholds from 2025 onwards.
Is ESG Reporting Mandatory in Australia?
Yes. The Treasury Laws Amendment (Financial Market Infrastructure and Other Measures) Act 2024 introduces mandatory climate-related financial disclosures under AASB S1 and AASB S2.
The regime applies in three phased groups based on size and listing status.
1. Group 1 (FY2025): large listed and large unlisted companies
Group 1 covers companies meeting two of three thresholds: 500+ employees, $1 billion in revenue, or $1 billion in gross assets. Reporting begins for financial years starting 1 January 2025.
These entities must disclose climate risks, Scope 1 and Scope 2 emissions, governance processes, and scenario analysis from year one. Scope 3 emissions disclosure applies from their second reporting year.
2. Group 2 (FY2026): medium listed and unlisted companies
Group 2 applies to entities meeting two of: 250 or more employees, $200 million in revenue, or $500 million in gross assets. Reporting obligations begin for financial years starting 1 July 2026.
These businesses follow the same AASB S2 content requirements as Group 1, however, they receive modified assurance timelines and transitional relief on Scope 3 emissions during the initial reporting cycles.
3. Group 3 (FY2027): smaller listed and financial institutions
Group 3 applies to entities meeting two of: 100 or more employees, $50 million in revenue, or $25 million in gross assets. It also captures asset owners holding $5 billion or more. Reporting starts 1 July 2027.
Smaller entities may scope disclosures to material climate risks only, yet they still need to document governance, strategy, risk management, and metrics in line with AASB S1 and AASB S2.
4. Voluntary ESG reporting: who should start now even if not yet required
Private companies, mid-market suppliers, and not-for-profits often face ESG data requests from banks, insurers, and customers. Voluntary reporting prepares them for audit-grade disclosure before obligations arrive.
Australian exporters into the EU, UK, and Japan also face buyer-driven ESG questionnaires. Therefore, starting a voluntary AASB S2-aligned report now protects future contracts when thresholds shift.
Why ESG Reporting Matters for Australian Businesses
ESG reporting is no longer a marketing exercise. It now carries legal, commercial, and reputational consequences that affect access to capital, contracts, and insurance. Three drivers explain the shift.
1. Meeting ASIC obligations and avoiding greenwashing risk
ASIC holds active enforcement powers against misleading sustainability claims. Since 2023, it has issued infringement notices and commenced Federal Court actions against superannuation funds and listed companies.
Accurate ESG reporting, backed by documented sources and methods, is therefore the primary defence. Vague net-zero pledges, statements without evidence, or selective disclosure all attract regulator scrutiny.
2. Responding to investor, lender, and supply chain demands
The Big Four Australian banks now embed ESG data into credit assessments and sustainability-linked loans. Large investors like AustralianSuper and Aware Super also require AASB S2-aligned disclosures.
Large buyers such as Woolworths, BHP, and Telstra also cascade ESG questionnaires down supply chains. Consequently, suppliers without structured data risk losing tenders, pricing, or preferred-vendor status.
3. Building long-term business resilience and reputation
Climate risk, workforce turnover, and governance failures erode enterprise value over time. ESG reporting forces structured measurement, giving boards early warning of issues financial statements cannot surface.
Transparent reporting strengthens trust with customers, talent, and communities. For example, Australian companies publishing audited emissions data often outperform peers on retention and loyalty metrics.
ESG Reporting Frameworks Used in Australia
Australian businesses typically combine a mandatory standard with voluntary frameworks.
The mandatory layer covers compliance, while voluntary frameworks address investor expectations and global comparability.
1. AASB S1 and AASB S2: Australia’s mandatory sustainability reporting standards
AASB S1 sets general sustainability disclosure requirements across governance, strategy, risk, and metrics. AASB S2 focuses on climate disclosures, including physical risk, transition risk, and scenario analysis.
Both standards align with the ISSB baseline. Australian entities in Groups 1, 2, and 3 apply AASB S2 from their commencement dates, with AASB S1 following as the framework matures.
2. GRI (Global Reporting Initiative): the most widely used voluntary framework
The GRI Standards remain the dominant voluntary framework for full ESG reporting in Australia. They cover universal, sector, and topic-specific disclosures across environmental, social, and governance pillars.
GRI suits companies wanting stakeholder reporting beyond climate. For example, ASX-listed miners pair AASB S2 climate statements with a GRI-aligned report covering tailings, community, and workforce topics.
3. TCFD: the climate framework now incorporated into AASB S2
The Task Force on Climate-related Financial Disclosures framework introduced the four-pillar structure now embedded in AASB S2: governance, strategy, risk management, and metrics and targets.
Australian entities reporting under TCFD, such as APRA-regulated banks under CPG 229, can transition to AASB S2 with limited rework. The disclosure logic stays the same, though required metrics become more specific.
4. ISSB / IFRS S1 and S2: the global standards behind Australia’s AASB S1/S2
The International Sustainability Standards Board issued IFRS S1 and S2 in June 2023. The AASB then adopted these with minor Australian modifications, producing AASB S1 and AASB S2 for local use.
For multinationals, this alignment means one global ESG data set can satisfy Australian, UK, Japanese, and Singaporean regimes, subject to differences in scope, timing, and assurance.
5. CDP and UN SDGs: supplementary voluntary disclosure channels
CDP runs an annual questionnaire covering climate, water, and forests. Many Australian listed companies respond because institutional investors use the scores in engagement and voting decisions.
The UN Sustainable Development Goals provide a high-level outcome framework. Businesses typically map ESG initiatives to relevant SDGs inside a GRI report, rather than producing a standalone SDG disclosure.
Types of ESG Reports
Australian businesses rarely produce a single all-encompassing document. Instead, ESG reporting has split into distinct report types, each serving specific stakeholders, frameworks, and assurance needs.
1. ESG annual / sustainability report (GRI-aligned)
This is the flagship narrative report, published alongside the annual financial report. It covers all three ESG pillars, materiality outcomes, stakeholder engagement, and progress against prior commitments.
Length ranges from 40 to 120 pages for ASX 200 companies. Investor relations, sustainability, and communications teams jointly own the content, with external assurance often applied to Scope 1 and 2 emissions.
2. Climate risk disclosure report (AASB S2 / TCFD)
This report satisfies mandatory AASB S2 and focuses exclusively on climate-related financial risks and opportunities. It covers governance, strategy, scenario analysis, risk processes, and quantified metrics.
Unlike a GRI sustainability report, the climate disclosure sits inside or alongside financial statements. Therefore, it falls under director sign-off and auditor assurance, with legal weight equal to financial data.
3. GHG emissions report (Scope 1, 2, and 3)
A greenhouse gas inventory report quantifies emissions across operational boundaries. Scope 1 covers direct emissions, Scope 2 covers purchased energy, and Scope 3 spans value chain emissions in 15 categories.
Australian entities generally follow the GHG Protocol Corporate Standard, supplemented by NGER Act methods for regulated facilities. It often feeds AASB S2 climate statements and GRI-aligned disclosures.
4. Environmental performance report
This report extends beyond emissions to cover water, effluent, waste, recycling rates, land use, biodiversity, and air pollutants. It is common in resources, utilities, manufacturing, and agriculture.
Australian mining and energy firms typically publish an environmental performance report to meet state licence conditions, NGER reporting, and community expectations. It also feeds GRI and AASB S2 disclosures.
5. Social and workforce report
The social report covers demographics, gender pay gap, injury rates, training hours, turnover, community investment, and modern slavery due diligence. It targets regulators, unions, investors, and communities.
Data sources include HR systems, Safe Work Australia incident logs, WGEA submissions, and Modern Slavery Act statements. A social report often consolidates information already produced for regulatory lodgements.
6. Governance disclosure report (AASB S1)
The governance report covers board composition, independence, diversity, committee structures, executive pay, ethics policies, and cyber-risk oversight. AASB S1 formalises sustainability-related governance disclosure.
ASX-listed companies usually integrate governance disclosures into the corporate governance statement. However, private companies preparing voluntary ESG reports can adopt the same structure for lender readiness.
7. ESG KPI progress report (quarterly / annual)
This is an internal or investor-facing update tracking ESG KPIs against targets. Common metrics include emissions intensity, renewable energy share, lost-time injury frequency rate, and board diversity.
Quarterly cadence suits companies with sustainability-linked loans or bonds where covenants reference KPI thresholds. Annual cadence is standard for most Australian businesses outside regulated finance.
8. Materiality assessment report
A materiality report documents which ESG topics are financially significant and most important to stakeholders. It sets the scope and priorities for all subsequent ESG reporting and target-setting activity.
The process combines stakeholder surveys, peer benchmarking, regulatory review, and risk data. Outputs typically include a materiality matrix, a priority topic shortlist, and linkages to GRI, AASB S2, and ISSB.
| Report type | Primary framework | What it covers | Main audience |
|---|---|---|---|
| ESG annual / sustainability report | GRI Standards | Full E, S, and G narrative with materiality, stakeholder engagement, and progress against prior commitments. | Investors, customers, employees, public |
| Climate risk disclosure report | AASB S2 / TCFD | Mandatory climate-related governance, strategy, scenario analysis, risk processes, and metrics with director sign-off. | Regulators, investors, auditors |
| GHG emissions report | GHG Protocol / NGER Act | Scope 1 direct, Scope 2 purchased energy, and Scope 3 value chain emissions across 15 categories. | Auditors, regulators, sustainability teams |
| Environmental performance report | GRI 300 series, state licences | Water, effluent, waste, recycling, land use, biodiversity, and air pollutants beyond emissions. | Regulators, communities, operations leaders |
| Social and workforce report | GRI 400 series, WGEA, MSA | Demographics, gender pay gap, injury rates, training, turnover, community, and modern slavery due diligence. | Regulators, unions, investors, communities |
| Governance disclosure report | AASB S1, ASX CGC Principles | Board composition, independence, diversity, committees, executive pay, ethics, and cyber-risk oversight. | Boards, lenders, shareholders |
| ESG KPI progress report | Internal KPI / loan covenants | Quarterly or annual tracking of defined ESG KPIs against targets, including variance and RAG status. | Executives, lenders, investors |
| Materiality assessment report | GRI 3, AASB S1/S2, ISSB | Documents which ESG topics are financially significant and most important to stakeholders, with priority shortlist. | Boards, sustainability and risk teams |
What to Include in an ESG Report
A robust ESG report combines quantitative metrics, qualitative narrative, and forward-looking targets. The following five components form the minimum content set expected by regulators, investors, and auditors in Australia.
1. Environmental metrics: GHG emissions (Scope 1, 2, 3), energy, water, waste
Report Scope 1 and 2 emissions in tonnes of CO2-equivalent using NGER or GHG Protocol methods. Scope 3 should cover material categories such as purchased goods, business travel, and downstream product use.
Include energy consumption split by renewable and non-renewable sources, water withdrawal and discharge, and total waste with diversion-from-landfill rates. Use the prior reporting year as a baseline.
2. Social metrics: workforce, health & safety (Safe Work AU), community, modern slavery
Disclose headcount by gender, employment type, and location, alongside voluntary turnover rates and the WGEA-reported gender pay gap. Include training hours per employee and apprenticeship intake numbers.
Report lost-time injury frequency rate, total recordable injury rate, and fatalities under Safe Work Australia methodology. A modern slavery statement is required for entities with revenue above $100 million annually.
3. Governance metrics: board composition, executive pay, risk management, ethics
Disclose board size, independent director ratio, gender split, average tenure, and attendance rates. Provide the charter and membership of audit, risk, remuneration, and sustainability committees.
Summarise the executive remuneration framework, including the share linked to ESG KPIs. List ethics, whistleblower, anti-bribery, and conflict-of-interest policies, plus any material breaches in the year.
4. Materiality assessment and stakeholder engagement process
Document how you identified material ESG topics. Describe the stakeholder groups consulted, engagement methods used, and the scoring system applied to rank financial significance against stakeholder importance.
Present the outcome as a materiality matrix, then cross-reference each priority topic to the relevant AASB, GRI, or ISSB disclosures. Refresh the assessment at least every two years.
5. Climate scenario analysis and forward-looking targets (AASB S2)
AASB S2 requires scenario analysis under at least two pathways, including one consistent with the Paris 1.5°C goal. Describe time horizons, physical risks, transition risks, and quantified impacts.
Forward-looking targets should include absolute or intensity emissions reductions, interim milestones, and the base year. Explain assumptions and dependencies, especially where Scope 3 reductions rely on suppliers.
Free ESG Report Templates
The following eight templates cover the most common ESG reporting formats used by Australian businesses. Each is structured to align with AASB S1, AASB S2, GRI Standards, and Safe Work Australia data requirements.

How to Start ESG Reporting
Starting ESG reporting follows a repeatable six-stage process. Treating it as a structured project, with defined owners and deliverables, prevents late-cycle rework and reduces the assurance burden in year one.
1. Determine your reporting obligations (mandatory group or voluntary)
Check whether your entity meets Group 1, 2, or 3 thresholds under AASB S2. Confirm your commencement date, first reporting period, and Scope 3 relief window, then document the conclusion in a board paper.
If you fall outside mandatory groups, review lender, investor, and customer data requests from the past 12 months. Where requests are frequent, voluntary AASB S2-aligned reporting is the practical start point.
2. Conduct a materiality assessment
Identify ESG topics that are financially significant and important to key stakeholders. Combine internal risk data, peer disclosures, regulatory scans, and stakeholder surveys to build a balanced topic list.
Plot topics on a two-axis matrix, then shortlist 8 to 12 priorities. This shortlist defines the scope of your first report, the KPIs you collect, and the narrative sections the final document requires.
3. Choose your ESG framework(s)
Select a mandatory framework where applicable (AASB S1 / S2) and one voluntary framework, typically GRI. Add sector frameworks where relevant, such as SASB for financial services or ICMM for mining.
Map the chosen frameworks to your material topics. Each disclosure should appear once, in the report section where it fits most naturally. This prevents duplication and reduces data collection workload.
4. Collect, verify, and organise ESG data
ESG data comes from HR, finance, operations, procurement, and facilities systems. Build a central repository with owners, source documents, calculation methods, and version control for every metric.
Internal verification should happen before external assurance. Reconcile totals to underlying systems, check unit conversions, document estimates, and retain supporting evidence for at least seven years.
5. Write, structure, and design your ESG report
Draft in plain English, lead with material topics, and include both narrative and data tables. Aligning section order with the framework index helps assurance providers locate evidence efficiently.
Design should reinforce readability, not decoration. Use consistent charts for trend data, include year-on-year comparisons, footnote methods, and publish a data appendix for machine-readable tables.
6. Get assurance and publish
Mandatory AASB S2 reporters must obtain reasonable assurance on the climate statement by the phase-in date. Voluntary reporters typically seek limited assurance on selected metrics such as Scope 1 and 2.
Publish on the corporate website, lodge with ASIC where required, and file with ASX for listed entities. A press release summarising key metrics supports investor relations, media, and internal communications.
Australian ESG Reporting Requirements in 2025–2027
Australian ESG reporting requirements span legislation, regulatory guidance, and accounting standards. Understanding how they interact is critical for compliance planning from FY2025 to FY2027.
1. AASB S1 and AASB S2
AASB S2 introduces mandatory climate-related financial disclosures, phased across three groups between FY2025 and FY2027. It covers governance, strategy, risk, metrics, and quantified emissions.
AASB S1 extends beyond climate into broader sustainability risks and opportunities. Its application is optional for now, however, investor and lender pressure is pushing adoption ahead of mandatory dates.
2. ASIC enforcement and the real risk of greenwashing claims
ASIC treats misleading sustainability claims as a corporate conduct priority. Between 2023 and 2025, it secured penalties against Vanguard, Mercer Superannuation, and LGSS Pty Ltd for greenwashing breaches.
Any ESG claim, target, or label used in marketing, fund names, or product disclosure documents must have documented evidence. ESG reporting and marketing approval processes should therefore be linked.
3. NGER Act, APRA CPG 229, and the Modern Slavery Act
The National Greenhouse and Energy Reporting Act requires facilities above defined thresholds to report to the Clean Energy Regulator annually. NGER data often seeds the Scope 1 section of AASB S2 statements.
APRA’s CPG 229 sets climate risk management expectations for banks, insurers, and super funds. The Modern Slavery Act 2018 requires entities with revenue over $100 million to publish an annual statement.
ESG Reporting Best Practices for Australian Businesses
Australian businesses that treat ESG reporting as an operational discipline achieve better data quality, lower assurance costs, and stronger stakeholder outcomes. Four practices separate leaders from laggards.
1. Start with Scope 1 and 2 emissions before tackling Scope 3
Scope 1 and 2 rely on data you already control: fuel records, fleet logs, and electricity invoices. Mature these calculations, reconcile to financial systems, and obtain assurance before tackling Scope 3.
Scope 3 requires supplier engagement, activity factors, and often estimation. Tackling it in year two lets you build supplier data portals, define boundaries, and avoid the risk of material restatements.
2. Align with AASB S2 even if not yet in a mandatory group
Entities outside current thresholds will face obligations as customer and lender pressure rises. Voluntary adoption of AASB S2 structure prevents costly rework when thresholds shift or buyer demands accelerate.
The AASB S2 four-pillar structure also forces board-level engagement with climate risk. Therefore, even businesses reporting only a few metrics in year one benefit from the governance discipline it enforces.
3. Use centralised ESG software to manage data collection and reporting
Spreadsheets do not scale beyond the first reporting cycle. ESG data sits in finance, HR, operations, procurement, and facilities systems, each with different owners. Errors compound across handoffs quickly.
A centralised ESG platform integrat2ed with ERP and HR systems automates data capture, applies emission factors, tracks KPIs, and generates audit-ready trails. Reporting cycle time drops 40 to 60 percent.
4. Build external assurance readiness into year-one processes
Assurance providers assess documentation quality, not just the numbers. Therefore, maintain source evidence, calculation memos, and version-controlled approvals for every disclosure.
Early engagement with assurance firms during the data collection phase surfaces gaps before they become findings. This lowers second-year fees and reduces the risk of qualified opinions on sustainability statements.
Conclusion
ESG reporting has moved from voluntary communications to a core compliance, finance, and risk function for Australian businesses. AASB S1 and AASB S2 set the baseline, phased from FY2025 through FY2027.
Matching framework choice to obligations and investing in centralised data systems reduces assurance risk. Businesses treating ESG reporting as a discipline, backed by the right software and internal ownership, achieve compliance with ease.

Frequently Asked Question
ESG reporting focuses on investor-grade disclosure of environmental, social, and governance metrics that affect financial value. Sustainability reporting is broader and can include operational, community, and brand narrative content beyond financial materiality.
First-year mandatory AASB S2 reporting typically costs between $150,000 and $600,000 for mid-sized listed entities, covering data systems, consulting, and assurance. Voluntary reporters with strong internal data can publish for $30,000 to $80,000.
Under AASB S2, directors are legally accountable for the climate statement, similar to financial statement sign-off. In practice, the CFO, chief sustainability officer, and audit committee prepare the content, with the full board approving the final disclosure.
Small businesses are not currently in any mandatory group, however, they often face ESG data requests from larger customers, banks, and insurers. Therefore, many Australian SMEs publish a short voluntary ESG summary to protect contracts.
Most Australian businesses publish annually, aligned with the financial year. Companies with sustainability-linked finance often add quarterly KPI updates for covenant monitoring, and larger entities may issue mid-year climate risk updates.
