For the better part of a decade, ESG reporting in Australia was essentially voluntary storytelling. Companies published sustainability reports that were heavy on aspirational language and light on verifiable data. Nobody was checking the numbers because there were no standardised numbers to check.

That era is ending. The Australian Sustainability Reporting Standards (ASRS), aligned with the International Sustainability Standards Board (ISSB) framework, are now mandatory for large listed entities from January 2025, with progressively wider coverage through 2027. This isn’t optional corporate goodwill anymore. It’s financial reporting, subject to assurance requirements and regulatory scrutiny.

The problem? Most companies don’t have the systems, data, or processes to produce this reporting at anything approaching financial-grade quality. And that’s creating a fast-growing market for ESG reporting technology.

The Reporting Challenge

Financial reporting has had decades to mature. Companies have ERP systems, chart of accounts structures, internal controls, audit processes, and trained accountants who understand AASB standards. The entire ecosystem exists to produce accurate, comparable financial statements.

ESG reporting has none of that maturity. Consider what a company now needs to report under the ASRS standards:

Scope 1 and 2 emissions. Direct emissions and energy-related emissions. This requires metering data from every facility, energy consumption records, fleet fuel data, and industrial process emissions. Many companies don’t have this data in any centralised system.

Scope 3 emissions. Supply chain emissions, business travel, employee commuting, end-of-life treatment of products. This data often doesn’t exist in any reliable form. Companies are estimating based on industry averages and spend data, which produces numbers of questionable accuracy.

Climate-related risks and opportunities. Scenario analysis showing how climate risks affect the business under different temperature pathways. This requires modelling capabilities that most companies don’t have.

Governance and strategy disclosures. How the board oversees climate-related risks, how climate considerations are integrated into strategy. These are qualitative disclosures but they need to be consistent and verifiable.

Producing all of this with the rigour expected of financial reporting—audit trails, internal controls, segregation of duties, third-party assurance—is a fundamentally different challenge from publishing a glossy sustainability report.

The Technology Response

A cohort of Australian and international technology companies are building platforms to address this gap. The market segments roughly into four categories.

Data Collection and Aggregation

The foundational layer. Companies like Sumday, Pathzero, and Emitwise are building platforms that ingest data from multiple sources—utility bills, fleet management systems, procurement platforms, facility management software—and convert it into emissions and sustainability metrics.

The technical challenge here is data quality. Utility bills arrive in different formats. Energy contracts have varying tariff structures. Facility data may be manual or partially automated. The platforms need to normalise, validate, and reconcile data from dozens of sources with different update frequencies and reliability levels.

Reporting and Disclosure

Platforms that take aggregated data and produce reports compliant with ASRS, ISSB, GRI, CDP, and other frameworks. Workiva, Diligent, and several Australian entrants are competing in this space.

The value proposition is automation and consistency. Rather than manually populating templates in spreadsheets, companies feed validated data into a reporting platform that generates disclosures in the required format, with automatic cross-referencing and consistency checks.

Carbon Accounting

Specialised platforms focused specifically on greenhouse gas emissions measurement, reporting, and verification. These often include supply chain modules that estimate Scope 3 emissions based on procurement data, industry emission factors, and (increasingly) supplier-specific data.

Scenario Analysis and Risk Modelling

The most technically sophisticated category. Platforms that help companies model climate-related risks and opportunities under different scenarios (typically 1.5°C, 2°C, and 3°C+ pathways) and translate those into financial impacts. Companies like XDI and Climate Risk Engines are building these capabilities for Australian market conditions.

Market Dynamics

Several forces are shaping how this market will develop.

Urgency is driving adoption. Large listed entities needed to report from January 2025. Many discovered during their first reporting cycle that their existing processes were inadequate. Technology procurement that might normally take twelve months is being compressed to three or four months.

The Big Four are positioning aggressively. Deloitte, PwC, EY, and KPMG are all building ESG advisory and assurance practices and partnering with technology platforms. Their influence on enterprise technology selection is significant—if your auditor recommends a specific platform, that carries weight.

Integration with financial systems is critical. ESG data increasingly needs to flow into the same systems that produce financial statements. Companies using SAP or Oracle for financial reporting want ESG data integrated into those environments, not sitting in a separate platform. SAP and Oracle have both acquired or built ESG modules, but they’re early-stage and often limited.

Data availability remains the binding constraint. The best reporting technology in the world can’t overcome the fundamental problem that much ESG data doesn’t exist yet in reliable, auditable form. Particularly for Scope 3 emissions, companies are working with estimates and proxies. The technology platforms are only as good as the data they receive.

Our View

The ESG reporting technology market in Australia is at an inflection point. Mandatory reporting requirements have created genuine, urgent demand. The technology is maturing rapidly. Investment is flowing into the sector.

But we’d caution against assuming this market will consolidate quickly around a few winners. ESG reporting is inherently complex, with different industries, frameworks, and jurisdictions requiring different approaches. We expect a fragmented market with specialised platforms serving specific segments rather than a single dominant platform.

The companies that will win in this market are those that solve the data quality problem—not just the reporting format problem. Any platform can produce a nicely formatted report. The hard part is ensuring the numbers in that report are accurate, auditable, and comparable.

That’s where the real value lies, and it’s where most of the technology investment should be focused.
