Q1/Q2 - 2025
Hyperledger Climate Action & Accounting Special Interest Group (CA2SIG) 1H 2025
Date
Jul 9, 2025
Jeff Pribich (U.S.) has the role of Chair, which became effective 01/01/2025.
Overall Health
A new initiative is underway to bring climate experts into the SIG, with a focus on those skilled in developing climate accounting solutions through technologies. Current focus is on decentralized ledger and those with deep expertise in specific topics such as Scope 3 emissions and the carbon offset market. To increase visibility and engagement, future meetings featuring these experts are expected to be promoted through platforms like Meetup.
The SIG has experienced a continued low level of activity throughout the first half of 2025, extending the downward trend observed in the latter half of 2024. Bi-weekly meetings have seen minimal attendance, often limited to just one or two participants. In response to this sustained decline, a new meeting strategy has been implemented: regular bi-weekly meetings are no longer automatically scheduled. Instead, meetings will now be convened on an as-needed basis, such as when a topical webinar is organized or when a SIG member initiates interest. This approach remains flexible and subject to change; if engagement improves, the SIG will resume its bi-weekly meeting cadence.
What's Working Well
The group is working closely with the Standards WG in the development of the data ontology for climate accounting. This group is present at the weekly meetings and will be utilizing this ontology in the net-zero digital twin (NZDT) architecture.
This group is to be more tightly aligned with the Supply Chain and Trade Finance SIG(SC-TF) due to Greenhouse gas emissions(GHG) from transportation as a significant portion of overall global emissions. Solutions arising from this SIG are expected to be in a joint form with SC-TF.
This group and SC-TF are engaged in a joint project to produce a solution and technical architecture for the development of a digital twin. The digital twin will enable supply chains real-time measurement of carbon and other greenhouse gas emissions from supply chains. In addition, modeling of a supply chain to reduce and optimize GHG emissions to net zero is a primary function. Note: This is not a buildout of a digital twin. It is the technical architecture for its development, utilizing Hyperledger platforms and tools.
The first “joint SIG” Meetup presentation from the digital twin vendor SimWell is scheduled for September 19th.
The project to produce a solution and technical architecture for a Hyperledger based digital twin was submitted as a mentorship project. It was approved by the mentorship committee. Several interviews for the mentorship position were conducted. Ed Chang was nomination and will now be the mentee involved with the architecture development whilst learning a new skill. Ed is now on this project through the end of November.
Issues and Challenges
As previously mentioned in the “Overall Health” section of this report, there is a very low level of attendance in our group SIG meetings at this time, forcing a change in scheduling.
There is a need to ensure all LFDT parties are in agreement on what content is presented from vendors in our presentations. Is the content solely focused on Hyperledger/blockchain technologies or focused on climate subjects such as scope 3 and auditability of climate measurements for reporting? In the SIG’s current form there is no SIG charter.
There exists a need for additional technical skills focused on Hyperledger tools, including solution architecture and coding to provide for new projects that include prototyping. Our mentee will assist with the effort in this area.
Thus far, we are short-staffed in our efforts to contact firms for presentations. To increase interest in this SIG, there is a need to host presentations that are focused on very topical subjects related to climate accounting and the impact on climate change. Bringing on a mentee will free up more time, away from the NZDT architecture project, to spend time researching and contacting firms.
Overall Activity in the last 6 months
The SIG has focused 90% of its efforts on the net-zero digital twin architecture.
We have been working with the Standards WG on development and testing of the data ontology often referred to as the “Knowledge Graph”. Here is an extract from the Standards WG:
“A digital twin will typically have to interact with a combination of climate/environmental accounting protocols, standards, and methodologies. To facilitate consistent data handling and accounting across these different protocols, standards and methodologies, the digital twin can utilize the AIA Ontology developed by LFDT’s Climate Action and Accounting SIG “Standards Working Group”.
Planned Work Products
Rather quickly, a strategy to increase interest in this SIG and enable it to move forward and be more viable. Thoughts thus fare are the following:
Utilize Meetup for presentations in place of the Zoom link. This may be a better approach to highlight our presentations.
Integrate a LinkedIn group with close to 1 million users. We have placed a very short sample of our architecture work on the digital twin on this LinkedIn site. Thus far, over 900 downloads have occurred reflecting carbon accounting for supply chains has great interest. How do we bring these interested parties into our SIG?
Hosting future webinars.
Produce a solution architecture for a Net-Zero Digital Twin Supply Chain template using Hyperledger technologies. This work requires contributions from multiple Hyperledger SIGs and technical assistance from Hyperledger technical staff.

Upon completion of the net-zero digital twin technical architecture by the end of November 2025, investigate options to obtain funding to develop a working model and prototype utilizing LFDT
