The study arrives at a pivotal moment for Chinese corporate disclosure. As the world’s second-largest economy and one of the largest contributors to global greenhouse gas emissions, China plays a decisive role in global climate mitigation. Since the government announced its ‘Dual Carbon’ targets — peaking carbon emissions before 2030 and achieving carbon neutrality by 2060 — Chinese corporations have shifted from largely voluntary corporate social responsibility practices toward increasingly structured and mandatory ESG reporting. This transition has dramatically increased the volume and visibility of environmental disclosures, but it has also created new challenges in evaluating their credibility and comparability. Reporting practices remain highly variable across sectors, with companies differing in how they present strategies, how much detail they provide, and how they balance narrative description against quantitative data.

The conceptual heart of the research lies in distinguishing between two dimensions of disclosure that are often conflated: sentiment and substance. Sentiment captures the narrative tone of a report — the positivity or negativity of its language — while substance captures the reporting density of specific environmental strategies, such as carbon emission reduction, renewable energy adoption, or waste management. The authors ground this distinction in three complementary theoretical perspectives. Signaling theory views corporate disclosure as a mechanism for reducing information asymmetry between companies and stakeholders. Impression management theory highlights how firms frame and emphasize information to shape perceptions. Disclosure-quality perspectives emphasize that the usefulness of reporting depends not on volume alone but on specificity and relevance. Narrative–substance divergence, the researchers stress, is not evidence of deception; it may arise from reporting conventions, sector characteristics, regulatory requirements, or communication practices.

To build the indicator, the team assembled a purposive sample of twenty large, high-visibility Chinese corporations, four each from five contrasting sectors: Finance, Energy, Food and Beverage, Technology, and Automotive. The selection criteria reflected corporate scale, market relevance, and environmental relevance — including asset size, revenue, market capitalization, and sales volume, complemented where available by MSCI ESG ratings. The Finance group included giants such as the Industrial and Commercial Bank of China and Ping An Insurance; the Energy group included Sinopec, PetroChina, China Shenhua and CNOOC; the Technology group spanned Tencent, Alibaba, JD.com and Baidu; and the Automotive group featured BYD, SAIC Motor, Geely Holding and NIO. For each corporation, the researchers analyzed the environmental section of the 2024 fiscal-year ESG or Sustainability Report, excluding front matter, executive statements, governance sections and appendices to ensure consistency across the corpus.

The resulting dataset was substantial: 520,071 words and 675,304 tokens of environmental text. The NLP pipeline began with preprocessing steps — tokenization, normalization, stop-word removal, and lemmatization — with Chinese-language segmentation performed using the Jieba library in Python, while English versions of reports were consulted only to verify terminology. Because general-purpose sentiment dictionaries often miss the specialized vocabulary of environmental reporting, the team built a domain-specific lexicon combining established Chinese sentiment dictionaries, sector-specific terminology from finance, environmental science, technology and manufacturing, and ESG-specific terms identified during corpus preparation. A Sentiment Score was then calculated for each report, normalized to a range from −1 (strongly negative) to +1 (strongly positive), with token-count normalization reducing the influence of differences in report length.

Substance was measured through normalized keyword-frequency analysis across seven environmental strategy categories: carbon emission reduction, energy consumption improvement, water recycling and reduction, waste management, renewable energy adoption, carbon neutrality achievement, and Nature-based Solutions adoption. Keyword frequencies were expressed as mentions per 1,000 tokens, drawing on themes common to established frameworks such as the Global Reporting Initiative, SASB, and MSCI, while also reflecting China’s Dual Carbon policy context. The Sentiment–Substance Indicator then compared the two dimensions relatively within the sample: reports combining comparatively high sentiment with lower substance were interpreted as showing greater narrative–substance divergence, while the reverse pattern indicated closer alignment. Crucially, the researchers emphasize that the indicator is a diagnostic screening tool, not a verdict on corporate behavior or actual environmental performance.

The results are revealing. The Technology sector showed the lowest average Sentiment Score (0.02) and the highest Substance Metric (72.0), corresponding to relatively higher disclosure alignment — a near-neutral narrative tone paired with dense reporting of specific strategies, including high mention frequencies for carbon emission reduction (15.2) and waste management (13.8). The Finance group presented the contrasting picture: the highest average sentiment (0.16) alongside the lowest substance (54.0), indicating relatively lower alignment within the sample. The authors suggest a plausible explanation: financial institutions report environmental strategies through financed emissions, green finance, portfolio exposure and climate-related investment rather than direct operational measures, which may naturally produce different disclosure profiles. Energy, Automotive, and Food and Beverage occupied intermediate positions, with sentiment scores between 0.11 and 0.13 and substance values between 61.2 and 64.2. The Food and Beverage sector, for instance, emphasized water-related strategies (11.2 mentions per 1,000 tokens), reflecting water’s role as a key production input, while showing comparatively low reporting of renewable energy (7.2).

Reliability was tested against a manually annotated dataset of 500 sentences, 100 from each sectoral group, each classified as positive, neutral or negative. The automated classification performed consistently across sectors, with accuracy ranging from 82.9 to 88.5 percent and F1 scores from 82.3 to 85.3 percent, providing an empirical basis for using the Sentiment Score as the narrative component of the indicator. The study also examined Nature-based Solutions — afforestation, ecosystem restoration, and land management practices that enhance carbon sequestration — as reported by the corporations. The Energy group reported the highest aggregated values: 7.56 billion Yuan in NBS investment, 10.0 million trees planted, and 3.252 million tons of CO2-equivalent in reported carbon offsets. PetroChina alone reported 3.41 million trees planted in 2024, including 1.624 million trees under an ‘Afforestation Campaign for 10,000 Well Sites’. The Technology group reported the lowest aggregated planting (1.20 million trees) and offsets (0.327 million tons CO2e). The authors caution that these figures are corporation-reported and were not independently verified, and that reported offsets do not address issues of additionality, permanence, or long-term sequestration.

The implications extend to both assessment practice and policy. For investors and regulators, the indicator offers a complementary screening layer: reports showing relatively greater narrative–substance divergence could be flagged for closer examination using independent environmental-performance data. The computational structure is suitable for scaling to much larger collections of ESG reports, although the authors stress that performance and interpretability require validation on broader and more representative datasets. On the policy side, the findings suggest that standardized disclosure requirements — particularly regarding specific environmental strategies and measurable information — could improve comparability and reduce ambiguity, and that the goal should be greater specificity and transparency rather than simply more disclosure volume.

The limitations are candidly acknowledged. The sample of twenty corporations is an exploratory benchmark, not a statistically representative slice of Chinese business; the analysis covers a single reporting year; the Substance Metric is sensitive to the choice of keyword taxonomy; and the NBS figures rest on unverified corporate claims. Yet as a proof of concept, the study marks a meaningful step forward. By rigorously separating how companies talk about the environment from what they actually report doing, the Sentiment–Substance Indicator gives regulators, investors and researchers a transparent, replicable instrument for interrogating the fastest-growing genre of corporate communication on Earth — and a reminder that in the age of green narratives, the most important question is not how confident a company sounds, but how concretely it reports.

The study, published in SN Social Sciences by Adriana Kirley Santiago Monteiro of the Federal University of Piauí and colleagues, applied critical discourse analysis (CDA) to the 2022 ESG reports of the two Brazilian-born companies ranked as the most responsible in the country’s cosmetics and perfumery sector: Natura and Grupo Boticário. Using the Merco ESG responsibility ranking, a benchmark corporate reputational assessment in Latin America, the team identified four sector leaders, Natura, Grupo Boticário, Avon and L’Oréal, but excluded Avon and L’Oréal because they originate in the United States and France respectively. The remaining two reports were read in full, coded and annotated with the help of ATLAS.ti software, a qualitative analysis tool the authors describe as providing transparency, systematicity and rigor to social science research.

The theoretical backbone of the analysis is the three-dimensional model of discourse developed by linguist Norman Fairclough, which treats any text as simultaneously a linguistic object, a product of discursive practices such as production and distribution, and a form of social practice embedded in ideology and power. In practical terms, the researchers examined everything from vocabulary, grammar and politeness to intertextuality, the way a text connects to other texts, and interdiscursivity, the way it borrows from the discourses of other communities. At the deepest level, they asked how the reports construct realities, which aspects of the social process they emphasize, and which they quietly push into the background. This layered approach matters because, as the authors argue, language is not a neutral container for facts but a constitutive element of reality itself, capable of maintaining or restructuring power relations when its ideological work goes unnoticed.

What the researchers found in the textual dimension of the reports was a deliberate blend of the informative and the persuasive. Both companies organize their documents into thematic sections, but rather than presenting dry managerial data, they intersperse policies and performance figures with narratives, photographs, testimonials, graphs and links. The result is a hybrid genre that informs while it persuades, meeting the demands of a heterogeneous audience that may include investors, suppliers, employees, policymakers and consumers encountering the reports through social media. Both firms deploy accessible language for social and environmental information alike, a notable finding because prior studies have shown that companies often bury environmental performance in complex prose, possibly because stricter reporting standards make that data harder to manipulate. The high readability of these two reports is consistent with evidence that better ESG performers tend to write more clearly, while weaker performers may use complexity as a smokescreen.

The reports also reveal subtle mechanisms of what Fairclough calls interactional control. Interactive navigation lets readers prioritize topics and change the sequence of information, yet arrows, “learn more” notices, color schemes, icons and animated graphics steer attention toward the meanings the companies intend to construct. Natura reinforces its environmental identity through iconography, pairing symbols of finance with leaves: the icon representing investors combines a branch of leaves with a pile of coins, while the icon for consultants links a human figure, coins and foliage in a cycle. The company even likens its ESG report to the mirror of the Negro River, suggesting that, like the water, the document faithfully reflects the company’s actions throughout 2022, a metaphor that simultaneously asserts transparency and reaffirms the brand’s bond with nature. Grupo Boticário, meanwhile, builds an emotional framework around its packaging take-back program, displaying a trash can stickered with the phrase “Your empty packaging is full of love for the future” above the silhouette of one of its perfumes, surrounded by green paper hearts and a circular arrow.

At the level of discursive practice, the analysis found that both companies distribute their reports proactively rather than reactively, publishing them in full on their websites and pointing readers to complementary platforms. The reports circulate across multiple media and mix discursive genres, incorporating questions, invitations, calls to action, hashtags and slogans such as Grupo Boticário’s #umabelezadefuturo, which means “a beauty of the future.” Personal pronouns like “we,” “you” and “everyone” create closeness with readers, while Natura uses testimonials and stories to forge emotional connection and a sense of belonging. Crucially, both companies anchor their credibility through intertextuality, invoking the United Nations, the Sustainable Development Goals and the Global Compact. The researchers note that such appeals to external authorities can legitimize business discourse and conceal possible contradictions between corporate activity and genuine sustainable development, especially when the reports do not explain how those external principles were applied or verified.

The deepest layer of analysis, discourse as social practice, exposed the ideological work underlying the companies’ priorities. Natura highlights climate action, nature regeneration, social impact, circularity and value distribution, while Grupo Boticário directs its practices toward packaging and waste, water, biodiversity, climate emergencies and emissions, energy, renewable ingredients, diversity in the value chain and community development. Both discourses foreground social and environmental identity while overshadowing financial and economic aspects, a pattern the authors say mirrors major global companies that emphasize contributions and commitments while distancing themselves from the environmental and social impacts of their own economic activity. This shift extends to imagery: both companies replace pictures of irreversible environmental disasters with images of preservation and community integration, promoting a restructuring of the roles that companies and society play in discourse.

One of the study’s most striking findings concerns passivation, the grammatical treatment of people as recipients rather than agents. Companies emerge as active subjects of social and environmental causes, while surrounding communities appear either as objects of corporate action, as in Grupo Boticário’s statement that suppliers and neighboring communities “are subject to periodic assessments of human rights violations,” or as beneficiaries, as in Natura’s commitment to “ensure decent wages for employees and create livelihoods for local communities.” The researchers also identify what they call opportunity language, a strategy that transforms political problems into management challenges. When addressing risks, both reports enumerate opportunities for improvement alongside their commitments and mitigation practices, positioning the companies as allies of society. The authors interpret this as a means of maintaining hegemonic positions, using symbols, narratives and metaphors to tell a safe story about the causes and consequences of business actions, particularly relevant given that Natura previously faced fines over the irregular use of Brazilian biodiversity and Grupo Boticário had to clarify possible responsibility for degradation in a reserve area.

The analysis also catalogued three categories of discursive weakness: hasty generalization, false causality and appeal to authority. Hasty generalization appeared more frequently in Grupo Boticário’s report, for example when the company announced the gradual replacement of only “some” animal-derived components yet concluded that its products are composed of biodiversity inputs without providing sufficient data for verification. False causality surfaced more often in Natura’s report, notably in a statement that the company must attend to vectors of value creation that are “not just financial value, but economic value,” a framing the researchers say wrongly implies the two are mutually exclusive and overlooks social, environmental and cultural value. Appeals to authority, mainly references to the SDGs and the Global Compact, appeared with equivalent frequency in both reports, lending credibility without always explaining how the references were operationalized. The authors caution that such weaknesses do not prove intentional misconduct; they may reflect short-term adaptation pressures or simple lack of knowledge.

The study’s authors are candid about its limits. Because it relies exclusively on self-reported ESG documents, the findings primarily reflect the companies’ intended narratives rather than independently verified sustainability outcomes, and the researchers recommend that future work triangulate reports with interviews of suppliers, workers and communities, along with direct observation. Still, the contribution is significant: applying critical discourse analysis to ESG reports in the Brazilian cosmetics sector is an underexplored approach, and the findings illuminate how organizations in emerging economies manage their socioenvironmental image under intense stakeholder scrutiny. For companies, the practical message is that linguistic precision matters, since hasty generalizations and false causal framings can undermine even well-intentioned sustainability strategies and feed perceptions of greenwashing. For the rest of us, the lesson is simpler and more unsettling: the fight over sustainability is fought not only in supply chains and laboratories but in prepositions, pronouns and pictures, and reading corporate green claims critically may be as important as reading them at all.

The central finding is striking: similar products made by different manufacturers can vary enormously in their nutritional and environmental profiles. A ready meal produced by one company might score far worse on both counts than a broadly comparable product sold by a rival. This variation matters because it means that the differences are not dictated by the category itself. If one manufacturer can produce a more nutritious and more sustainable version of a given food, then others in the same category can plausibly do the same. The gap between the best and worst performers within a product type represents, in effect, an untapped reservoir of public health and environmental benefit.

To quantify what could be gained from closing that gap, the authors modelled a scenario in which manufacturers replaced some of their least nutritious and least sustainable products with alternatives scoring closer to the average for their category. The results showed significant potential for improvement across the board. More remarkably, for many manufacturers, more than half of the total achievable improvement could be secured by reformulating or replacing just 10 percent or less of their product line. In other words, a relatively small number of targeted changes could deliver the majority of the benefit, a finding that reframes portfolio reform as a tractable, near-term opportunity rather than a distant aspiration.

The study is, according to its authors, the first of its kind to assess the capacity of food and beverage manufacturers to support both nutrition and environmental sustainability through changes within their existing product portfolios. Lead author Eleanor Hammond, who conducted the research while working at the University of Oxford, explained that the analysis was designed around what companies could realistically do without inventing entirely new product categories. That focus on the existing portfolio is what gives the findings their practical force: the improvements identified do not depend on breakthrough technologies or consumer behaviour change, but on decisions about which products to keep, reformulate, or retire.

The distribution of improvement potential across companies is far from uniform. The researchers found that two well-known British supermarkets, whose own brands collectively account for 28.9 percent of the sales value in the analysis, have some of the largest scope to improve their scores for both environment and nutrition. Broad product ranges spanning many categories give these retailers many opportunities to lift weaker performers toward the standard set by their better products. By contrast, manufacturers with narrow product ranges, such as snack and energy drink producers, generally have less room to improve their scores, since their portfolios offer fewer substitution possibilities and their categories may already sit near the average for the market.

Co-author Dr Michael Clark, Associate Professor in Sustainable Food Solutions at the Smith School of Enterprise and the Environment, framed the findings in terms of the wider transformation that food systems must undergo in the coming decades. If food systems are to transition to more nutritious and environmentally sustainable outcomes, he noted, food manufacturers are going to have to change the products they sell. That change, he argued, can either be driven by the manufacturers themselves or imposed on them by government policy. The study’s results, he said, show that manufacturers can get a head start on this necessary transition by making small changes to their product portfolios today, rather than waiting for regulation to compel action.

The timing of the research is significant. The UK Government is currently under pressure to bring forward legislation requiring mandatory reporting on the nutrition of UK food and beverage products, and the study offers a template for how such reporting could work in practice. According to Dr Clark, the study demonstrates how the UK Government could monitor both sustainability and nutritional outcomes together, rather than treating them as separate policy problems. He added that the approach could also be used for ESG reporting and could support regulatory frameworks such as the European Union’s Corporate Sustainability Reporting Directive, which requires large companies to disclose detailed information about their environmental and social impacts.

Methodologically, the study is an observational analysis rather than an intervention trial, but its scale gives it considerable weight. Assigning per-100-gram scores for both nutrition and sustainability to the full product ranges of 44 major manufacturers required a systematic assessment of a large share of the UK food retail market, covering approximately 50 percent of sales. Because the scoring was applied consistently across products and companies, the resulting variation cannot be dismissed as an artefact of differing assessment methods. The consistency of the measurement is precisely what allows the authors to compare improvement potential across manufacturers with very different portfolio structures, from diversified retailers to specialist snack producers.

The implications extend beyond the United Kingdom. Food manufacturers everywhere face mounting pressure from investors, regulators, and consumers to demonstrate progress on health and sustainability, yet many have struggled to identify where meaningful change is possible without disrupting their businesses. This study suggests a concrete answer: audit the portfolio, identify the products that fall furthest below category averages on nutrition and sustainability, and prioritise those for reformulation or replacement. Because the analysis shows that a small fraction of products carries a large share of the improvement potential, the approach offers companies a way to achieve substantial, measurable gains with limited commercial disruption. For policymakers, the same data infrastructure could underpin monitoring schemes that hold manufacturers accountable over time.

What makes the findings resonate is their simplicity. The debate over food system transformation is often dominated by visions of radical change, from novel proteins to wholesale dietary shifts, all of which face long timelines and uncertain adoption. This research points to something more immediate: the products that companies already make, and the gaps between them. If a ready meal from one manufacturer can be substantially more nutritious and sustainable than a similar product from another, then the knowledge and capability to produce better food already exists within the industry. The task, as the Oxford team frames it, is to close those gaps deliberately and quickly, whether through voluntary corporate action or through the reporting requirements now being considered by governments. With more than half the potential improvement available from changing just a tenth of a product line, the study makes a compelling case that the food industry’s next big contribution to public and planetary health may come not from new inventions, but from smarter choices about the products it already sells.

The review, conducted by Sunitha Prabhuram and Thamburaj Anthuvan of Manipal Academy of Higher Education in Dubai, followed the PRISMA 2020 protocol for systematic literature reviews. The researchers searched Scopus, supplemented by Google Scholar cross-searching, using Boolean strings that combined terms such as ESG materiality, sustainability materiality, financial materiality, impact materiality, and double materiality with disclosure and reporting terms. After identification, deduplication, title and abstract screening, and full-text eligibility assessment, 48 studies remained. Of the 38 studies excluded at the full-text stage, 18 lacked substantive engagement with materiality despite discussing ESG reporting broadly, nine had insufficient linkage to materiality-related frameworks, and 11 offered limited analytical contribution. A second reviewer independently audited a 25 percent subsample of the corpus to check coding consistency, with discrepancies resolved through discussion.

At the heart of the analysis lies a conceptual fault line that most casual observers of the ESG boom never see. Materiality, in traditional financial reporting, refers to information significant enough to influence the economic decisions of investors and other capital providers. Financial materiality carries this logic into the sustainability domain: an environmental or social issue matters only insofar as it affects expected cash flows, asset values, or the cost of capital. Climate transition risks, regulatory exposure, litigation threats, and supply chain disruptions all qualify under this lens because they translate into financial consequences for the firm. This investor-centered logic underpins the standards of the International Sustainability Standards Board, which anchors disclosure to enterprise value.

Impact materiality takes the opposite starting point. Rooted in stakeholder theory and sustainability governance, it requires companies to account for their effects on the world regardless of whether those effects ever touch the bottom line. Pollution, biodiversity loss, poor working conditions, and community displacement can impose enormous social and environmental costs even when profitability remains untouched. The Global Reporting Initiative is the most prominent framework built on this foundation. Double materiality, meanwhile, merges the two perspectives: a sustainability issue is reportable if it either affects enterprise value or represents a significant corporate impact on society and the environment. The European Union’s Corporate Sustainability Reporting Directive and its European Sustainability Reporting Standards, developed by the European Financial Reporting Advisory Group, institutionalize this hybrid approach, requiring firms to assess material issues across their entire value chain from both angles.

The review’s central finding is that these competing logics have not merged despite a striking convergence in reporting form. Frameworks now share standardized terminology, structured disclosure categories, and common expectations around governance, strategy, risk management, and metrics. The ISSB’s global baseline and the European standards have pushed standard-setters toward cross-framework mapping and interoperability efforts. Yet beneath this architectural alignment, the underlying assumptions about accountability remain irreconcilable. The ISSB regime serves capital providers and frames sustainability as an extension of financial reporting; the European regime serves a broader constituency of employees, regulators, civil society, and affected communities, and frames disclosure as an instrument of public accountability. Structural convergence, the authors argue, can coexist with endemic fragmentation.

The fragmentation extends into measurement practice. The reviewed literature reveals no standardized method for operationalizing materiality in empirical research or corporate reporting. Researchers rely on materiality matrices, formal double materiality assessments, disclosure indices, content analysis of sustainability reports, and narrative classification of ESG topics, each with different thresholds, coding conventions, units of analysis, and topic taxonomies. An issue deemed material in one study may be treated entirely differently in another, restricting cross-study comparability and hindering cumulative knowledge building. In corporate practice, firms operating across multiple regimes may use identical terminology while applying different assessment processes, stakeholder engagement procedures, and significance thresholds, meaning that materiality tests can be situation-specific rather than comparable across firms, industries, or jurisdictions.

The practical consequences ripple outward. For multinational companies, complying simultaneously with ISSB-style and European-style requirements means running parallel materiality assessments, documenting judgments under different logics, and preparing for assurance under divergent expectations. The review notes that newer European regimes have made materiality assessments more transparent, but most operational approaches still depend on individual firm interpretation, complicating assurance readiness and disclosure comparability. Investors and assurance providers, the authors suggest, need to consider the underlying materiality orientation of any sustainability report before comparing it across companies or jurisdictions, because two documents that look structurally similar may rest on fundamentally different judgments about whose interests the disclosure serves.

Why do these competing logics persist? The review points to deep institutional path dependence. Anglo-American reporting traditions have long emphasized investor protection and decision usefulness, while European systems have historically prioritized public accountability, a divergence now embodied in the contrast between the ISSB and the CSRD. Double materiality attempts to reconcile the two views, but the tension remains, and the literature is divided on whether financial and double materiality are complementary extensions of one another or genuinely competing disclosure philosophies. The authors also note that dynamic materiality, the idea that sustainability impacts may become financially material over time as externalities are internalized through regulation, litigation, or reputational pressure, appeared only indirectly in the reviewed studies, suggesting a promising theoretical frontier linking impact significance to financial significance.

Looking ahead, the review argues that a single global materiality standard is improbable. Instead, the authors predict a plural but synchronized future: growing structural coherence alongside persistent divergence in disclosure purpose. They reframe materiality itself, moving it from a technical reporting threshold to a multi-level disclosure-governance mechanism that connects institutional standard-setting, organizational reporting practice, and accountability orientation. The policy challenge, they contend, is not to force harmonization but to build interoperability, giving standard-setters, regulators, and firms clearer guidance on translating materiality considerations across the ISSB, ESRS, and GRI frameworks. Stronger internal governance for stakeholder engagement, assessment, documentation, and review would help companies navigate multi-regime compliance, while improved interoperability mechanisms could reduce compliance complexity and enhance the comparability and decision usefulness of disclosures worldwide.

The review also identifies a conspicuous blind spot: emerging economies. The corpus was dominated by empirical work shaped by European regulatory developments, and direct evidence on how firms in developing and transitional economies cope with conflicting disclosure obligations, limited institutional capacity, and assurance readiness remains scarce. The authors flag this absence as a priority for future research, alongside empirical studies of how firms implement simultaneous financial and impact assessments, the evolving role of assurance services across different materiality criteria, and the potential of interoperability models and double materiality approaches to function as translation systems between disclosure regimes. Until those gaps close, the global ESG reporting landscape will likely remain what this review says it already is: a two-track architecture in which the paperwork increasingly looks the same while the reasons for producing it continue to diverge.

The stakes are higher than corporate paperwork suggests. Battery material purchasers on the open market increasingly compare products using reported ESG data, and downstream manufacturers such as car companies are making procurement decisions based on sustainability disclosures. A review of reports from 90 corporate entities cited in the study found that sustainability disclosures lack completeness, consistency and comparability, with wide variations in reporting practices. Meanwhile, greenwashing has come under formal scrutiny in Australia through an investigation by the Australian Competition and Consumer Commission, raising the reputational cost of vague or inflated claims. If the data underpinning these decisions is not comparable, the entire traceability apparatus built around responsibly produced battery minerals starts to wobble.

The research team used qualitative content analysis to extract information from eight voluntary mechanisms, including certification schemes such as the Initiative for Responsible Mining Assurance (IRMA), Certification of Raw Minerals (CERA), Towards Sustainable Mining (TSM), the Global Reporting Initiative (GRI), the Carbon Disclosure Project (CDP), the Dow Jones Sustainability Index (DJSI) and the Responsible Mining Index (RMI), alongside the OECD Due Diligence Guidance on Stakeholder Engagement. They also examined three Australian federal legislative instruments: the National Greenhouse and Energy Reporting Act 2007, the National Pollutant Inventory measure, and the Environmental Protection and Biodiversity Conservation Act 1999. Each mechanism was assessed against a common set of criteria covering ESG categories addressed, data types required, methodological specifications, whether reporting occurred at site or corporate level, and transparency provisions.

The findings show partial alignment with significant fragmentation underneath. Several topics, including energy use, greenhouse gas emissions, labour practices and community engagement, appeared consistently across mechanisms. Yet the depth and specificity of requirements varied enormously, particularly regarding methodology, data quality and verification expectations. Variance was especially pronounced for water, air quality, climate change, energy, waste, and habitats and mine closure indicators. Even when multiple mechanisms addressed the same category, detailed analysis revealed significant differences in how results were derived and how much information was needed to satisfy reporting expectations.

Some schemes clearly went further than others. IRMA, for example, features highly detailed descriptions and criteria for meeting individual reporting categories, specifies the frequency at which reporting should be updated, and mandates assurance requirements, with surveillance audits conducted 12 to 18 months after initial audits and re-audits every three years. It also requires public reporting of information on company websites. By contrast, GRI’s requirements for evidence supporting reported information are less prominent, and several schemes lacked any mention of public reporting or clarity about what should be disclosed publicly. Compliance grading added another layer of complexity: TSM uses levels from C to AAA, while IRMA scores a percentage based on assurance requirements met, which complicates downstream comparison across standards.

Verification and governance practices diverged just as sharply. The researchers evaluated data quality principles, informed by ISEAL credibility guidelines and prior research linking independent third-party verification to reporting credibility. Only one regulatory instrument, the NGER scheme, required third-party auditing of reported greenhouse gas accounting information. Among voluntary mechanisms, internal and third-party auditing were more prevalent but not uniformly required. DJSI requires third-party verification every four years but not for all information, TSM requires it only for some disclosures, and RMI demands public disclosure of certain data without requiring independent verification of it. On governance, IRMA, TSM, GRI and RMI were all developed under multi-stakeholder governance involving indigenous groups, worker organisations, industry, financial institutions and researchers, while CERA was developed with a limited group of consultants and universities. Only IRMA and CERA specified grievance mechanisms outright, with TSM requiring them for workers.

The study situates this fragmentation in a longer history. Sustainability reporting in mining predates the Global Reporting Initiative, founded in 1997, and stretches back at least as far as Western Mining Corporation’s 1994/95 Environmental Progress Report, developed partly using North American guidelines from 1993. Australia has had mandatory corporate environmental reporting since 1998. Yet despite three decades of evolution, ESG frameworks have not reached a level of standardisation that enables meaningful performance comparison. The International Council on Mining and Metals released a draft Consolidated Mining Standard in October 2024, merging its Mining Principles with the CopperMark, Towards Sustainable Mining and the World Gold Council standards, but the authors caution that whether consolidation solves equivalency, comparability and data quality issues remains to be seen, particularly with implementation due in 2026 and uptake uncertain.

Regulatory pressure is building from multiple directions simultaneously. The European Union’s Battery Regulation will directly affect Australian battery material producers, while the proposed Carbon Border Adjustment Mechanism and the US Securities and Exchange Commission’s climate-related financial disclosure requirements signal a broader shift from voluntary towards mandatory ESG reporting. In Australia, comprehensive ESG disclosure has not yet been mandated beyond modern slavery and greenhouse gas reporting for larger companies, but a government position statement announcing an ‘Extended External Reporting regime’ hints at a future framework. Product-level platforms such as the Global Battery Alliance’s Battery Passport and the London Metal Exchange have responded to traceability demands by mandating specific reporting requirements, though their material scope remains limited.

The researchers sketch two divergent futures. In the consolidation trajectory, the proliferation of standards observed over 30 years reverses, driven by developments such as the International Sustainability Standards Board, which is working to consolidate SASB standards, TCFD recommendations, the Integrated Reporting Framework and the CDSB Framework. Industry-led consolidation is also visible in the international spread of Towards Sustainable Mining, adopted by the Minerals Council of Australia among others, and in the Copper Mark’s adaptation into Molybdenum, Nickel and Zinc Marks in 2022. However, the Consolidated Mining Standard has drawn pushback, with an open letter signed by more than 35 community groups, unions and NGOs advocating for alternatives such as IRMA, which they viewed as developed through an equal governance model, revealing tension between industry and broader stakeholders. In the proliferation trajectory, new standards emerge focused on specific concerns like modern slavery or individual commodities, potentially fragmenting along geographic lines between the USA, China and Europe, though interoperability could improve through blockchain-supported data systems and the United Nations Transparency Protocol, whose test pilots are now underway in Canada, Australia and the Democratic Republic of Congo.

For Australian producers, the immediate reality is a choice between expensive workarounds. Larger companies are building bespoke concordance matrices that align reporting criteria across multiple standards, an approach that demands sizable internal sustainability teams or costly external consultants. Smaller producers, or projects still in the scoping phase, often find that investment exceeds the perceived value. Some companies adopt a single strong standard such as IRMA in the hope that it satisfies others, though the scheme’s rigour can create hesitation among producers wary of unfavourable findings. The study’s authors do not pretend to have an exhaustive picture, acknowledging that the landscape is evolving rapidly and their analysis reflects a specific moment in the FBI CRC project. But their central conclusion is clear: the current landscape exhibits moderate overlap without full standardisation, and this fragmentation risks undermining comparability and stakeholder confidence. They recommend that all stakeholders in battery material supply chains articulate the future they want when advocating for change, because whether the sector consolidates or proliferates, the credibility of every green claim attached to a battery mineral depends on it.
