India Power Pilot Report

India Power Corporation Limited, a leading power generation and distribution company in India, piloted the E-liability method across its electricity value chain. Focusing initially on coal- and wind-generated electricity, the pilot established an accounting foundation for India Power’s long-term goal of delivering real-time, energy-source-specific emissions data to customers, while identifying data gaps, building internal capabilities, and assessing opportunities to scale the approach across its broader operations.

A Reference Architecture for Implementing E-ledgers Carbon Accounting on the Finternet
By Karthik Ramanna, Abhishek Sankritik, Lauren Holloway, Pramod Varma, and Vineet Nair

This paper outlines the minimum reference technology architecture needed to operationalize E-ledgers carbon accounting across complex value chains using Finternet-compatible infrastructure. The paper identifies the core accounting principles that must be preserved for E-ledgers to function correctly, including mass and energy conservation, complete emissions attribution, and full accounting integrity, and shows how these requirements shape the system architecture. Building on these foundations, we describe the key architectural layers, data structures, and information flows required to support interoperable carbon accounting across organizations, while maintaining appropriate controls over data visibility and ownership. A detailed example illustrates how information moves through the system in practice. The paper concludes by examining the governance, audit, and institutional arrangements necessary to deploy E-ledgers at scale across jurisdictions, industries, and enterprise systems.

Yorkshire Water and Feralco Group Pilot Report

We partnered with Yorkshire Water and Feralco Group to apply the E-liability approach to treated water, establishing the specific emissions embedded in the water treatment process. The pilot focused in particular on ferric sulphate, a coagulant widely used in water treatment, and demonstrated the value of supplier-specific emissions data in identifying reduction opportunities across the supply chain. By collaborating closely with Feralco, the pilot uncovered innovations that could reduce emissions associated with ferric sulphate by 40-50% compared to industry-average estimates, highlighting how more precise accounting can drive meaningful operational improvements.

A Candid Conversation with Professor Karthik Ramanna about Carbon Accounting and Reporting
Robert Eccles and Karthik Ramanna

Professor Karthik Ramanna, our co-founder, sat down with Professor Robert Eccles for a wide-ranging and candid conversation on the future of carbon accounting and reporting. The discussion explores the origins and evolution of the E-ledgers framework, different theories of change for industrial decarbonization, and the role that product-level competition can play in accelerating progress toward shared climate goals. The conversation also engages directly with a number of debates and misconceptions about E-ledgers.

Fortescue and AirTrunk are Both Building a Carbon Export Advantage
Mark Barnaba and Karthik Ramanna

In an op-ed published in The Australian Financial Review, our co-founder Professor Karthik Ramanna and Mark Barnaba (Independent Director and Deputy Chairman, Fortescue) argue that, as markets shift from ambition to verification, the ability to demonstrate lower product-level emissions will increasingly shape trade, capital flows, and customer preference. Pointing to leading companies like Fortescue and AirTrunk, the piece highlights how leading Australian companies are already doing the operational work of decarbonization and why ledger-based carbon accounting is now the missing link to turning that into a durable export advantage.

Standardizing Carbon Accounting Worldwide With a Single, Robust, Cost-Effective System
By Vincent Aussilloux, Yann Coatanlem, and Karthik Ramanna

This Atlantic Council issue brief, co-authored by our co-founder Karthik Ramanna, argues that scaling climate finance and strengthening energy security require more rigorous and comparable carbon accounting. The authors call on members of the Climate Club to select a single robust, auditable, and cost-effective accounting framework, advancing ledger-based carbon accounting as a practical solution. The authors make the case that such a system would support credible carbon labeling, emissions-based trade measures, and more efficient climate finance.

E-ledgers Institute Welcomes the Carbon Measures-International Chamber of Commerce Expert Panel on Carbon Accounting

The Institute welcomes the recent establishment of the Expert Panel on Carbon Accounting, co-hosted by the International Chamber of Commerce and Carbon Measures, and endorsed by Sustainable Business COP. We expect the work of the Expert Panel will build on the robust conceptual foundations of ledger-based carbon accounting developed by our founders, Professors Robert Kaplan and Karthik Ramanna. In light of these developments, we seek to clarify the ongoing role and work of the E-ledgers Institute.

Exxon-Backed Coalition Sets Out Goals to Fix Carbon Accounting
By Perry Cleveland-Peck

A Wall Street Journal report covers the launch of the Technical Expert Panel on Carbon Accounting, co-hosted by Carbon Measures, a global coalition to advance product-level, ledger-based carbon accounting, and the International Chamber of Commerce. At a São Paulo event, our co-founder, Professor Karthik Ramanna, who co-chairs the Expert Panel in a personal capacity, outlined the value of the E-ledgers approach in ensuring emissions are counted only once and allocated to products across the value chain. The Institute itself is not affiliated with Carbon Measures or the Panel.
