ASRS, TCFD, and GRI are three sustainability reporting frameworks Australian companies keep encountering, and they serve different purposes. ASRS is Australia's mandatory climate disclosure regime. TCFD is the earlier climate framework, now absorbed into the ISSB standards that ASRS is built on. GRI is a broader, voluntary standard covering environmental, social, and governance impact.
For most Australian businesses the practical question is not which framework is best, but which ones apply and how they fit together. With ASRS Group 2 reporting starting for financial years from 1 July 2026, that question just became urgent for a much wider set of companies. Here is how the three frameworks compare, where they overlap, and what each one asks of your energy and emissions data.
What Are ASRS, TCFD, and GRI?
Each framework came from a different place and solves a different problem. Knowing where each one started explains why they sit together the way they do.
ASRS (AASB S1 and AASB S2). The Australian Sustainability Reporting Standards are Australia's adoption of the global ISSB baseline. AASB S2, the climate standard, is mandatory and took effect for reporting periods beginning on or after 1 January 2025. AASB S1, covering broader sustainability information, is voluntary. ASRS requires disclosure of climate risks, opportunities, and greenhouse gas emissions across Scope 1, 2, and 3.
TCFD (Task Force on Climate-related Financial Disclosures). The TCFD published its climate disclosure recommendations in 2017 and shaped how the world reports climate risk. It was never a mandatory standard on its own. The Financial Stability Board wound the Task Force down in 2023 once its recommendations were fully incorporated into the ISSB standards.
GRI (Global Reporting Initiative). GRI is the longest-standing sustainability reporting standard, first published in 2000. It takes an impact-materiality view: how your organisation affects the economy, environment, and people, reported to a broad set of stakeholders rather than investors alone. It remains voluntary worldwide, and widely used.
How Do ASRS, TCFD, and GRI Compare?
The clearest way to separate the three is across the dimensions that actually change what you have to do.
Jurisdiction and mandate. ASRS is Australian law, administered through the Corporations Act and overseen by ASIC. TCFD was a global voluntary framework with no single regulator. GRI is a global voluntary standard maintained by the Global Reporting Initiative. Only ASRS carries a legal obligation in Australia.
Mandatory or voluntary. ASRS, through AASB S2, is mandatory for entities that meet the size thresholds. TCFD was always voluntary and no longer exists as a standalone framework. GRI is voluntary, though many companies treat it as an expectation from investors, customers, and supply-chain partners.
Materiality lens. ASRS and TCFD both use financial materiality: the sustainability matters that affect enterprise value. GRI uses impact materiality: the organisation's effects on the outside world. This is the single biggest conceptual difference, and it is why GRI and ASRS answer different questions rather than competing.
Scope of topics. TCFD covered climate only. ASRS is climate-first, with AASB S2 focused on climate and AASB S1 extending to broader sustainability topics over time. GRI is the broadest of the three, covering emissions alongside water, waste, biodiversity, labour, human rights, and governance.
Assurance. ASRS requires assurance, phased in from limited assurance over Scope 1 and 2 emissions in the early years toward reasonable assurance later. TCFD carried no assurance requirement. GRI reports can be externally assured voluntarily, but nothing compels it.
Effective dates. ASRS applies now, phased by entity size. TCFD recommendations applied from 2017 and were retired in 2023. GRI has been revised repeatedly since 2000 through its universal and topic standards.
Energy and emissions data needs. All three ask for greenhouse gas data built on accurate energy consumption. ASRS and the TCFD structure require Scope 1 and 2, and in time Scope 3, with audit-grade traceability. GRI asks for the same emissions data within a wider disclosure. The data foundation is common to all three.
Is TCFD Still a Separate Framework?
No. The TCFD was disbanded in October 2023 after the Financial Stability Board judged its work complete. Its eleven recommendations were fully incorporated into IFRS S2, the ISSB climate standard that AASB S2 is based on. Reporting under AASB S2 means you meet the TCFD recommendations by default.
This matters for planning. If your organisation already reports against TCFD, you are not starting from zero on ASRS. The four TCFD pillars (governance, strategy, risk management, and metrics and targets) carry straight through into AASB S2. What changes is that the disclosures are now mandatory, more prescriptive, and subject to assurance. Treat existing TCFD work as a head start rather than a parallel track.
Which Framework Applies to Australian Companies?
For Australian entities, ASRS is the framework with legal force, and it phases in by size. You fall into a group if you meet at least two of the three thresholds.
Group 1 applies from 1 January 2025: 500 or more employees, $500 million or more in consolidated revenue, or $1 billion or more in gross assets.
Group 2 applies from 1 July 2026: 250 or more employees, $200 million or more in revenue, or $500 million or more in gross assets.
Group 3 applies from 1 July 2027: 100 or more employees, $50 million or more in revenue, or $25 million or more in gross assets.
GRI applies to no one by law, but if your investors, lenders, or largest customers expect a broad sustainability report, GRI is usually the standard they have in mind. TCFD, as a standalone choice, is effectively closed: new reporters should build on AASB S2 rather than adopt a retired framework.
Can You Report Under More Than One Framework?
Yes, and many organisations do. ASRS and GRI answer different questions, so they complement rather than duplicate. A company might disclose climate risk to investors under ASRS while reporting its broader environmental and social impact under GRI.
The standard-setters have supported this directly. The IFRS Foundation and GRI have published interoperability guidance so the emissions and energy figures behind an ISSB or ASRS disclosure can carry into a GRI report without being recalculated. The practical lesson is to collect your underlying data once, to an audit-ready standard, and map it into whichever frameworks you report against.
What Do All Three Frameworks Have in Common?
Strip back the differences and the three converge on one requirement: reliable greenhouse gas data built on accurate energy consumption. Scope 1 and Scope 2 emissions come directly from your electricity, gas, and fuel use across every site. If that data is incomplete, wrongly attributed, or impossible to trace, every framework you report against inherits the problem.
This is where most reporting programs actually struggle. The framework mapping is well documented. The hard part is producing consumption and emissions data that is complete across a portfolio, calculated with the right emission factors, and traceable enough to survive assurance. It is a utility data problem before it is a reporting problem.
How Utilified Supports Multi-Framework Sustainability Reporting
Utilified's Utility Management System (UMS) builds the data layer that ASRS, GRI, and the TCFD-based disclosures all depend on. One validated dataset, mapped into whichever framework you report against.
Automated data collection. UMS pulls electricity, gas, water, and fuel data from retailer portals, interval meter providers, and invoice uploads across your full portfolio, then captures, validates, and attributes every data point to the correct site.
Validated emissions calculations. The platform applies the correct NGA emission factors by state and reporting year for location-based figures, and tracks contractual instruments such as LGCs, PPAs, and GreenPower for market-based figures. Both methods come from one underlying dataset.
Audit-ready outputs. Before consumption data feeds an emissions calculation, UMS validates every invoice against contracted rates and published tariffs. Your numbers rest on data that has already been checked, with full traceability for assurance providers.
Portfolio-scale reporting. For multi-site operations spanning states with different grid emission factors, UMS consolidates everything into one consistent dataset, turning utility intelligence into reporting decisions your auditors and your board can trust.

Frequently Asked Questions
Is TCFD still used in Australia?
Not as a standalone framework. TCFD was disbanded in 2023 and its recommendations were absorbed into the ISSB standards that AASB S2 is based on. Australian companies now meet the TCFD recommendations by reporting under ASRS.
Is GRI mandatory in Australia?
No. GRI is voluntary everywhere, including Australia. Many companies still report under it because investors, lenders, and large customers expect a broad sustainability disclosure, but there is no legal requirement.
Does ASRS replace GRI?
No. ASRS covers climate-related financial disclosure using financial materiality, while GRI covers broader impact using impact materiality. They answer different questions, and many organisations report under both.
What is the difference between ASRS and AASB S2?
ASRS is the umbrella name for the Australian Sustainability Reporting Standards. AASB S2 is the mandatory climate standard within ASRS. AASB S1, the broader sustainability standard, is voluntary. In practice, when people say ASRS reporting they usually mean AASB S2.
Do Australian companies need to report Scope 3 emissions?
Yes, eventually. Under AASB S2, Scope 3 value-chain emissions become mandatory from an entity's second reporting year, after first-year relief. Building Scope 3 data capability early is one of the clearest lessons from the first wave of reporters.
