The International Chamber of Commerce and the carbon accounting coalition Carbon Measures have announced the first group of experts selected to support the development of a global, ledger-based carbon emissions accounting framework. The initiative aims to enable consistent tracking of emissions at both company and product levels across global value chains.

The expert panel marks the next phase of Carbon Measures’ work following the coalition’s launch in October 2025. The framework under development is intended to address long-standing gaps in carbon accounting by creating a system capable of capturing product-level emissions and carbon intensity data in a way that is interoperable across industries and jurisdictions.

 

Building a Ledger-Based Model for Product-Level Emissions

 

At the core of the initiative is the ambition to move beyond fragmented corporate reporting toward a shared emissions ledger that reflects how carbon flows through complex industrial supply chains. According to the ICC and Carbon Measures, the panel will help define the principles, scope, and real-world applications of this system, ensuring that it is usable for companies, investors, policymakers, and regulators.

The proposed framework seeks to support more accurate measurement of embodied carbon in industrial products, enabling better comparisons, clearer price signals, and more credible decarbonisation strategies across sectors such as energy, materials, chemicals, transport, and manufacturing.

A Coalition Anchored in Heavy Industry and Finance

 

Carbon Measures is led by Amy Brachio, former Global Vice Chair of Sustainability at EY, and brings together a group of major industrial, financial, and infrastructure players. Founding members include organisations such as ADNOC, Air Liquide, Banco Santander, BASF, Bayer, ExxonMobil, EY, BlackRock’s Global Infrastructure Partners, Honeywell, Linde, Mitsubishi Heavy Industries, Mitsui & Co., NextEra Energy, Nucor, the Port of Rotterdam, and Vale.

The breadth of the coalition reflects growing recognition that credible decarbonisation depends not only on corporate targets but also on shared accounting standards that work across borders and value chains.

 

Expert Panel Drawn from Industry, Science, and Policy

 

The newly appointed panel brings together expertise from industry, finance, academia, and civil society. Members include Amy Luers, Head of Sustainability Science and Innovation at Microsoft; Armin Knors, former Head of Engineering and Technology at Bayer; and Benedikt Plümper, Head of ESG Portfolio Management at Banco Santander.

The group also includes Billy Pizer, President and CEO of Resources for the Future; Jakob Stausholm, Fellow at the Blavatnik School of Government at the University of Oxford and former CEO of Rio Tinto; Kate Maher, Professor at Stanford University; Koushik Chatterjee, Executive Director and CFO at Tata Steel; Rachel Teo, Managing Director at a Singapore-based private family office; and Tatsuya Hoshino, Executive Strategist for Methanol and Ammonia at Mitsui & Co.

Aligning Carbon Accounting With Decarbonisation Goals

 

Amy Brachio said the level of interest in joining the panel reflects the urgency and complexity of fixing carbon accounting at a global level. She noted that many of the selected experts are long-standing leaders in emissions reduction who are motivated to contribute to a system that can support real-world decarbonisation rather than theoretical reporting.

The ICC and Carbon Measures confirmed that additional experts will be appointed ahead of the panel’s first meeting later this quarter. While ICC is leading the selection process, final appointments are being agreed jointly by both organisations.

 

Carbon Accounting as Economic Infrastructure

 

Andrew Wilson, Deputy Secretary General of the ICC, said the panel’s composition reflects the depth and diversity of expertise required to transform carbon accounting into a practical economic tool. He emphasised that robust, product-level emissions data is increasingly essential for accelerating decarbonisation across the global economy.

As climate policy, border carbon measures, green procurement rules, and transition finance continue to expand, the initiative signals a broader shift toward treating carbon accounting as shared infrastructure rather than voluntary disclosure. If successful, the framework could shape how emissions are measured, priced, and managed across global trade and industrial systems in the years ahead.
