The International Chamber of Commerce (ICC) and Carbon Measures have announced a significant expansion of their joint Technical Expert Panel (TEP), increasing the initial target for expert participation by 25% to accommodate a surge in global interest. This strategic expansion aims to bolster the development of a standardized, ledger-based carbon accounting framework, a move seen as critical for harmonizing climate-related financial disclosures and industrial sustainability metrics. By broadening the panel’s composition, the organizations intend to integrate a more diverse array of perspectives from academia, climate policy, finance, and heavy industry, ensuring that the resulting standards are both technically rigorous and practically implementable across various global markets.
The decision to scale up the panel follows a highly competitive selection process led by the ICC, which prioritized technical depth and geographic representation. The expanded roster now includes experts who will serve in their independent, personal capacities, ensuring that the final outputs reflect a broad spectrum of professional insights rather than the specific corporate interests of their affiliated organizations. This independence is vital for the panel’s credibility, particularly as it seeks to influence international trade policies and investment stewardship.
A Strategic Response to Global Decarbonization Needs
The expansion of the TEP comes at a time when the global business community is facing increasing pressure to provide transparent, verifiable, and granular data regarding carbon footprints. Current carbon accounting methods, often criticized for their reliance on high-level estimates and inconsistent "Scope 3" reporting, have created significant hurdles for companies attempting to track emissions across complex supply chains. The TEP’s primary objective is to move beyond these limitations by developing a ledger-based system that treats carbon emissions with the same level of transactional rigor as financial accounting.
The newly expanded panel joins an initial group of ten global leaders announced in January. This foundational group includes prominent figures such as Alicia Seiger of the Chan Zuckerberg Initiative, Amy Luers of Microsoft, and Armin Knors, the former Head of Engineering and Technology at Bayer. The inclusion of industrial heavyweights like Koushik Chatterjee of Tata Steel and Jakob Stausholm, a former CEO of Rio Tinto and current representative of the University of Oxford, underscores the panel’s focus on hard-to-abate sectors where accurate carbon measurement is most challenging.
Andrew Wilson, Deputy Secretary-General of the ICC, emphasized that the completion of the panel marks a "significant milestone." According to Wilson, the "highly complementary mix of global expertise" will be instrumental in creating a coherent approach to carbon accounting. He noted that the overwhelming response from the international community allowed the ICC and Carbon Measures to widen the panel’s scope, which will now support real-world solutions across diverse geographies and inform more effective policy and trade decisions.
Chronology of Development and Future Milestones
The roadmap for the TEP is structured to deliver actionable results within a tight timeframe, reflecting the urgency of the global climate crisis. The initiative began its formal recruitment phase late last year, culminating in the announcement of the first ten members in January. Following the recent expansion, the full panel is scheduled to convene for its inaugural meeting in April.
Between April and the end of 2025, the group will engage in intensive technical workshops and data analysis. The primary deliverable is a comprehensive report on the current carbon accounting landscape, expected by the end of Summer 2026. This report will serve as the blueprint for a model carbon accounting standard, incorporating an extensive analysis of existing methodologies, corporate needs, and international policy frameworks.
A key partner in this technical journey is S&P Global Energy. Serving as the independent knowledge partner, S&P Global Energy will provide the necessary data infrastructure and analytical tools to support the panel’s work. This partnership is expected to bridge the gap between theoretical accounting models and the practical data realities of global commodity and energy markets.
Supporting Data: The Current State of Carbon Reporting
The push for a ledger-based system is supported by data highlighting the inconsistencies in current environmental, social, and governance (ESG) reporting. According to various market analyses, while over 90% of S&P 500 companies publish sustainability reports, the methodologies used to calculate "product-level" emissions vary wildly. This lack of standardization makes it nearly impossible for investors to compare the carbon intensity of competing products or for companies to accurately assess the impact of their procurement decisions.
Furthermore, the rise of carbon border adjustment mechanisms (CBAM), such as the one implemented by the European Union, has created an economic imperative for accurate accounting. Under CBAM, importers must report the embedded emissions of certain carbon-intensive goods. Without a globally recognized, ledger-based standard, businesses face the risk of double counting, inaccurate levies, and significant administrative burdens. The TEP’s work aims to mitigate these risks by providing a verifiable framework that functions across global value chains.
Leadership and Governance: A Multistakeholder Approach
The selection process for the panel was meticulously designed to ensure balance and technical excellence. Shortlisted candidates were reviewed by the panel’s co-chairs: Amy Brachio, CEO of Carbon Measures, and Karthik Ramanna, a Professor of Business and Public Policy at the University of Oxford. Ramanna is widely recognized for his work on the "E-liability" accounting system, a method that applies traditional financial accounting principles to carbon emissions, which is expected to serve as a conceptual touchstone for the TEP’s work.
Amy Brachio noted that the high caliber of applicants reflects the momentum behind the project. "From academics and researchers who have spent careers studying these systems to corporate practitioners who operate within them every day, and to investors who depend on accurate data to make consequential decisions—that combination reflects our conviction that getting carbon accounting right is, fundamentally, a collective project," Brachio stated.
The inclusion of finance-sector representatives, such as Benedikt Plümper of Banco Santander and Rachel Teo from a Private Family Office in Singapore, ensures that the panel’s outputs will meet the stringent requirements of investment stewardship. As financial institutions increasingly integrate climate risk into their portfolios, the demand for "audit-ready" carbon data has reached an all-time high.
Global Recognition and Policy Implications
The significance of the TEP’s work was further validated by its inclusion in the COP 30 Global Climate Action Agenda Outcomes Report. Recognized as one of the key solutions for carbon accounting standard harmonization, the initiative was highlighted as a critical accelerator at the COP 30 summit. This recognition places the TEP at the center of the international climate policy stage, particularly as nations look toward Brazil for the upcoming COP 30 to deliver more concrete implementation strategies.
By aligning with the Global Climate Action Agenda, the ICC and Carbon Measures are positioning their framework not just as a corporate tool, but as a potential foundation for international regulatory alignment. The panel’s focus on "product-level" emissions data is particularly relevant for the "Circular Economy" and "Net Zero" targets set by various jurisdictions. If companies can track emissions at the product level through a ledger-based system, they can more effectively optimize their operations for decarbonization and provide consumers with transparent information.
Analysis of Broader Impacts
The move toward a ledger-based carbon accounting system represents a paradigm shift in how environmental impact is measured and managed. Historically, carbon accounting has been treated as a separate, often secondary, exercise to financial reporting. By integrating carbon into a ledger-based framework, the TEP is essentially proposing that carbon be treated as a "currency" of the modern economy.
This approach has several profound implications:
- Market Efficiency: Accurate data allows for better price discovery in carbon markets. When the carbon content of a product is known and verified, it can be priced more accurately, leading to more efficient allocation of capital toward low-carbon technologies.
- Supply Chain Transparency: A ledger-based system enables "emissions tracking" as goods move through the supply chain. Each participant in the chain adds their specific emissions to the product’s "E-ledger," providing the final buyer with a complete and verifiable carbon history.
- Regulatory Compliance: As governments move toward mandatory climate disclosures, a standardized model reduces the compliance burden on multinational corporations that currently navigate a patchwork of different reporting requirements.
- Incentivizing Innovation: When companies can precisely measure the reduction in emissions resulting from a new process or material, they have a stronger business case for investing in green innovation.
The TEP’s work, supported by the ICC’s vast network of over 45 million companies in more than 170 countries, has the potential to become the de facto global standard. While the road to Summer 2026 is long, the expansion of the panel and the involvement of high-level industrial and financial leaders suggest that the project has the necessary weight to drive meaningful change in the global economic landscape.
As the first full meeting approaches in April, the international community will be watching closely. The success of this initiative could determine whether the world can finally move past the "estimates and averages" era of carbon reporting into an era of precision, accountability, and verifiable climate action.
