Blockchain for Energy (B4E) is a non-profit, member-led consortium dedicated to driving digital transformation within the energy sector. Comprising major energy companies including Chevron, ExxonMobil, and Repsol, B4E was established to collaboratively develop and implement blockchain-based solutions that can enhance efficiency, reduce costs, and increase transparency across the industry.

‍

The consortium's flagship product is the B4ECarbon platform, an advanced digital measurement, reporting, and verification (dMRV) solution. This platform integrates AI and IoT with distributed ledger technology to provide a secure and auditable system for managing emissions data. It enables energy operators to track, report, and verify their environmental performance in near real-time, helping to prevent greenwashing and ensure compliance with global standards. The B4E Network & Platform, built on Hyperledger FireFly, serves as the foundational layer connecting all of the consortium's solutions in a decentralised environment governed by its members.

The B4ECarbon platform is built on the Hedera public network, and has been a member of the Hedera Governing Council since June 2025.

Demia is a climate infrastructure company that provides a sophisticated technology platform for securing and verifying data in environmental markets, particularly the carbon market. The company’s mission is to increase trust, reduce friction, and unlock value by creating a transparent and auditable foundation for climate data. 

The platform is centered around a "Zero-Trust Data Fabric," which ensures that environmental data—whether from on-site IoT sensors or manual inputs—is protected and verifiable from its source. This system creates a secure chain of custody for information, streamlining the complex processes of measurement, reporting, and verification (dMRV).

‍

As a key partner in the Hedera ecosystem, Demia leverages the Hedera Guardian, an open-source framework for auditable ESG assets. This integration allows Demia to anchor its verified data to the Hedera public ledger, creating an immutable record of a project's environmental impact. This is crucial for their clients—including carbon project developers, auditors, and corporate purchasers—who require undeniable proof of climate action to meet regulatory requirements and investor expectations.

Emtech is a financial technology company that provides a full-stack Central Bank Digital Currency (CBDC) platform for central banks and other financial regulators. Its purpose is to equip its clients with tools to issue their own digital currencies and to empower these institutions to lead innovation in financial services while ensuring regulatory compliance and stability.

‍

The company’s offerings are centered around two key products. The first is its CBDC Core Solution, which provides the underlying technology for a central bank to mint, distribute, and manage a digital currency. The second is its innovative Digital Regulatory Sandbox, a controlled environment where fintechs and other financial service providers can build and test new applications using the CBDC, all under the direct oversight of the regulator. This collaborative approach helps bridge the gap between innovators and policymakers.

‍

Emtech has a significant partnership with Hedera, having announced that its CBDC platform is built on the Hedera public ledger. By leveraging Hedera's high-throughput, secure, and low-energy network, Emtech can offer central banks a highly resilient and auditable infrastructure for their digital currency operations.
