Carbon Reporting Urgently Needs Fixing — Here’s How to Do It

By Robert S. Kaplan and Karthik Ramanna

Today’s carbon disclosures rely heavily on unverifiable, self-reported data and do not reflect the true emissions embedded in products and supply chains. In this Financial Times op-ed, our co-founders explain how the E-ledgers method brings accounting rigor to carbon reporting, enabling companies to track actual cradle-to-gate emissions in real time, differentiate products based on verified carbon content, and compete credibly on decarbonization. The article also highlights recent case studies, such as with Hitachi Energy, that show how better data can lead to smarter decarbonization decisions.

Finternet Labs and E-ledgers Institute Announce Collaboration on GHG Accounting

by E-ledgers Institute and Finternet Labs

The E-ledgers Institute is excited to announce a recent partnership with Finternet Labs, a pioneering non-profit with a mission to develop technologies and digital public infrastructure for the public good. The joint initiative will operationalize the E-liability methodology using distributed ledger technology (DLT) and tokenization, creating an interoperable technology-based tool to seamlessly exchange emissions data between diverse entities via low-cost public infrastructure. This collaboration represents a critical step toward scaling E-liability principles, fostering greater trust in emissions data, and aligning with emerging regulatory frameworks.

How BMW Started Auditing Emissions Across Its Supply Chain

by Karthik Ramanna and Lauren Holloway

Many suppliers lack the capacity to calculate the emissions embedded in their products. To address this challenge, BMW Group applied the E-liability method to its iX kidney grille, working closely with key suppliers to enhance direct emissions measurement capabilities. With the help of the Catena-X initiative, BMW Group engaged suppliers of all sizes, helping smaller ones build accounting capacity while aligning larger ones with sectoral best practices. This article highlights how to equip suppliers for direct emissions measurement and underscores the importance of developing protocols to audit data at the source, ensuring accuracy from the outset.

America’s Advantage in Clean Production Can Make Manufacturing Great Again

by Karthik Ramanna

At recent U.S. Senate confirmation hearings, policymakers debated how to reinvigorate domestic industry without triggering inflation or a trade war. Our co-founder, Professor Karthik Ramanna, explores an emerging solution to this: a dynamic emissions-based tariff system that accounts for actual product-level emissions. By using E-liability cradle-to-gate emissions accounting, tariffs can be fair, WTO-compliant, and innovation-driven.

IFC Report: Empowering Carbon Accounting: from Data to Action

by Alessandra Alfieri, Lauren Holloway, Ulf von Kalckreuth, Stephan Moll, Christian Schmieder, and Bruno Tissot

In February 2024, we supported an influential workshop on measurement, reporting, and dissemination of carbon content information at the Deutsche Bundesbank Regional Office in Hamburg, Germany. We are delighted to share the new BIS / IFC report summarizing key findings from this workshop, co-authored by Lauren Holloway (Chief of Staff). The report reinforces the need for collaboration among industries, statisticians, and policymakers to close data gaps and establish a robust global carbon accounting framework.
