TLDR: A study using LLMs analyzed 828 U.S. firms’ climate disclosures, finding that many companies engage in symbolic reporting and mimicry rather than transparent communication. While larger, higher-emitting firms disclose more, their quantitative targets often don’t align with their narrative tone. Surprisingly, low-emission firms showed the least commitment. The research highlights the need for stronger regulation to link climate commitments with verifiable actions and combat greenwashing.
In an era where climate change demands urgent action, companies are increasingly expected to disclose their environmental strategies and impacts. However, a new research paper titled “Discourse vs emissions: Analysis of corporate narratives, symbolic practices, and mimicry through LLMs” by Bertrand Kian Hassani, Yacoub Bahini, and Rizwan Mushtaq reveals that these disclosures often fall short, with many firms engaging in imitation and symbolic reporting rather than genuine, transparent communication.
The study, published on October 3, 2025, delves into the complex world of corporate climate disclosures, analyzing 828 U.S.-listed firms. It highlights a critical challenge: while companies are making climate commitments, the actual value of these disclosures is frequently undermined by vague language, inconsistent targets, and a tendency to mimic peers. This behavior can make it difficult for investors and stakeholders to differentiate between truly committed companies and those merely “greenwashing” their image.
Unpacking Corporate Climate Narratives with AI
To understand these intricate communication patterns, the researchers employed advanced large language models (LLMs) specifically fine-tuned for climate communication. These LLMs acted as sophisticated classifiers, evaluating corporate sustainability and annual reports across four key dimensions:
- Sentiment: How companies frame climate change (as a risk, opportunity, or neutral).
- Commitment: Whether firms explicitly state climate mitigation or adaptation commitments.
- Specificity: The level of detail in their climate actions (general statements vs. verifiable actions).
- Target Ambition: If companies disclose explicit emission reduction goals or net-zero pledges.
By linking these narrative indicators to firm attributes like emissions, market capitalization, and sector, the study provides a comprehensive view of disclosure maturity.
Key Insights from the Analysis
The analysis yielded several important findings:
Firstly, firms that focus on climate risks in their narratives tend to make more explicit and specific commitments. However, the study found a disconnect between the tone of their communication and their quantitative targets, such as net-zero pledges. This suggests that while companies might acknowledge risks, their measurable goals don’t always align with their stated concerns.
Secondly, larger companies and those with higher emissions generally disclose more commitments and actions. Yet, these disclosures are often inconsistent with their quantitative targets, indicating a reliance on symbolic practices rather than concrete, measurable progress.
Thirdly, a striking observation was the widespread similarity in disclosure styles across different firms. This “mimetic behavior” suggests that companies often copy their peers’ reporting approaches, which reduces the uniqueness and usefulness of their disclosures for decision-making. This imitation can mask a lack of substantive engagement with climate goals.
Challenging Assumptions: What the Hypotheses Revealed
The research tested several hypotheses, leading to some surprising conclusions:
- Higher Emitters and Generic Commitments: The study supported the idea that highly emitting firms are more likely to issue generic or omit explicit climate commitments, often to manage their public image rather than demonstrate real change.
- Lower Emitters and Ambitious Targets: Contrary to expectations, firms with the lowest emissions showed the least commitment, specificity, and ambition in their climate targets. This challenges the assumption that lower emissions automatically lead to more credible climate disclosure.
- Inconsistencies and Greenwashing: While inconsistencies between narrative tone and concrete targets were observed, they were not widespread. However, their presence still points to areas where companies might be engaging in “greenwashing” – making ambitious claims without solid operational backing.
- Firm Size, Sector, and Disclosure Quality: Larger firms and those in specific sectors (like Materials and Industry) tended to have more explicit and higher-quality disclosures, though the overall differences by size and sector were modest.
- The Pervasiveness of Mimicry: The study strongly supported the hypothesis that firms, especially within the same sector, tend to mimic each other’s disclosure styles, driven by institutional pressures and peer benchmarking.
Implications for Policy and Practice
These findings underscore the limitations of voluntary reporting in ensuring credible climate information. The authors suggest that regulators and standard-setters need to implement stronger requirements for specificity and ensure that ambitious announcements are backed by verifiable interim goals and operational plans. Sector-specific guidelines and third-party assurance could help combat mimicry by directly linking communication to performance metrics.
The study also highlights the immense value of LLMs for analyzing complex ESG narratives at scale, offering a powerful tool to move beyond traditional metrics and assess the true maturity of corporate climate integration. For more details, you can read the full research paper here.

Conclusion: Bridging the Gap Between Talk and Walk
Ultimately, this research reveals a significant gap between corporate climate discourse and actual emissions reduction strategies. While many companies are talking about climate action, a substantial portion of this talk is symbolic, imitative, or lacks concrete, measurable objectives. Bridging this gap will require not only technological advancements in analysis but also robust regulatory frameworks that demand genuine transparency and accountability, ensuring that corporate climate narratives truly align with a decarbonized future.
