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.

Measuring the Carbon Footprint for Health Systems and Suppliers

A Collaborative Field Study by Providence Health System and Becton-Dickinson

by Robert S. Kaplan, Scott Hudson, Oriana Turley, Maureen Mazurek, and Beth Schenk

The E-ledgers Institute partnered with Providence Health System (PHS) and Becton Dickinson to track the emissions from manufacturing and transporting seven high-volume syringes to three PHS hospital sites, and from their subsequent use and disposal. The study demonstrates how the E-liability approach, through supplier-specific data collection and causal allocation, enables more accurate product-level carbon accounting, revealing where health system emissions accumulate and opportunities to lower those emissions.

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.

A Pro-Market Framework for Driving Decarbonization: Part II
by Karthik Ramanna

In this follow-up to Part I, our co-founder, Professor Karthik Ramanna, sets out the core design features of the E-ledgers system. He explains how such a system avoids double counting, is auditable, and can be deployed at low cost by leveraging existing accounting infrastructure. Ramanna then outlines a practical pathway to scale, starting with emissions-based border tariffs grounded in robust product-level accounts.

A Pro-Market Framework for Driving Decarbonization: Part I
by Karthik Ramanna

In this first installment of a two-part series, our co-founder Professor Karthik Ramanna examines, using concrete examples, why top-down decarbonization policies have struggled to meaningfully reduce global greenhouse-gas emissions. Because emissions stem from billions of decentralized decisions, he argues for a bottom-up, market-driven approach enabled by a universal, product-level emissions-accounting system (the E-ledgers system). Such a system would enable customers and investors to act on their preferences, spur competition among firms to reduce embedded emissions, and catalyze bottom-up innovation across supply chains. The piece sets up the stage for Part II, which outlines the accounting principles needed to build such a system.

Error Check: Correcting basic misconceptions in Bob Eccles’ Forbes column on E-ledgers and the GHG Protocol
by Karthik Ramanna and Robert S. Kaplan

Bob Eccles’ recent Forbes column identifies how E-ledgers carbon accounting can overcome the limitations of the GHG Protocol. His article reflects the preferences of many others for major changes to the GHG Protocol and its ecosystem. This note addresses some erroneous claims Eccles makes about challenges with implementing the E-ledgers system.

Carbon Accounting Must be Overhauled to Save Net Zero. Here’s How
by Alicia Seiger

In this Trellis feature, Alicia Seiger, Director of Climate at the Chan Zuckerberg Initiative and E-ledgers board member, explains the difference between carbon reporting and accounting. She highlights how reporting provides top-down emissions information, while E-ledgers accounting fully counts and allocates all emissions, enabling durable carbon markets, net-zero governance, decarbonization investment, and accountability.
