dotD Selected for METI's FY2025 Subsidy Project to Develop Automotive LCA Application for Supply Chain Data Platform

dotD Inc. (Headquarters: Minato-ku, Tokyo; Representative Director and CEO: Hisashi Onoda; hereinafter "dotD"), a business creation firm, announced that it has been selected as the operator for the "Development and Demonstration of Automotive LCA Application" under the Ministry of Economy, Trade and Industry's "FY2025 Subsidy for Energy Rationalization Technology Development (Demonstration and Popularization Project for Building a Supply Chain Data Linkage Platform)" (hereinafter "the Project"). The executing agency for the Project is the Automobile and Battery Traceability Center (hereinafter "ABtC").

For this Project, dotD will participate by carrying out additional development and modifications based on its proprietary prototype application for the automotive LCA domain, "LCA App for POC", which the company has been developing through self-investment.

■ Overview of the Selected Project

- Project Name: FY2025 Subsidy for Energy Rationalization Technology Development (Demonstration and Popularization Project for Building a Supply Chain Data Linkage Platform)
- Executing Agency: Automobile and Battery Traceability Center (ABtC)
- dotD's Role: Development and demonstration of the automotive LCA application

The Project is a demonstration and popularization initiative aimed at promoting the visualization and linkage of carbon dioxide emissions across the entire automotive supply chain, thereby contributing to both strengthening industrial competitiveness and reducing CO2 emissions. dotD will develop and provide the automotive LCA application and work on demonstrating the supply chain data linkage platform.

■ Details of dotD's Initiatives

Prior to the start of this Project, dotD independently developed the prototype application "LCA App for POC" for the automotive LCA domain through self-investment. During the project period, dotD plans to use this prototype as a base to add and modify functions, primarily focusing on the following, to provide an application environment for the Project conducted by ABtC:

- Development of business functions (collection, calculation, transmission, and reception of CFP information, etc.) defined in the "Guidelines for Data Linkage Mechanisms in Automotive Life Cycle Assessment, Alpha Version".
- Data model/data quality support, including the implementation of functions to select the scope and granularity of shared data, and the ability to maintain breakdowns by boundary, part, material, and energy.
- Primary unit database linkage, including user/sub-user license authentication calls and user/sub-user information search/update calls.
- Enhancement of connection functions with the supply chain data linkage platform, such as authentication methods, data transmission/reception APIs, status management, notification confirmation, and request/response workflows.

Furthermore, dotD plans to add and modify the following functions as independent proprietary developments:

- Expansion of business functions (contract operations, impact analysis, industry average calculation, etc.) defined in the "Guidelines for Data Linkage Mechanisms in Automotive Life Cycle Assessment, Alpha Version".
- Implementation of input, maintenance, and transmission functions for the Data Quality Rating (DQR) to handle data models/data quality.
- Implementation of call functions corresponding to the primary unit DB system's license management functions (classification management, availability control, usage logs, calculation method control).
- UI/UX improvements considering the business characteristics of automotive LCA.
- Strengthening responses to non-functional requirements such as performance, availability, security, and operational monitoring.

A portion of the deliverables from this Project is scheduled to be released as open source. By implementing it with a technology stack of Go lang / Next.js / TypeScript, dotD aims to promote the diversification of implementation references in the industry and contribute to expanding the base of the entire automotive LCA ecosystem.

■ Related Achievements

dotD has been continuously undertaking the following initiatives in the environmental compliance domain of the automotive and battery supply chain:

- Provision of the proprietary product "dotD CFP Calculator" (a CFP calculation SaaS compliant with the European Battery Regulation. Acquired ABtC application certification in March 2025).
- Selected for METI subsidy projects for four consecutive terms (two terms for the FY2023 "Demonstration and Support Project for CASE Adaptation such as Unmanned Autonomous Driving", and the FY2024/FY2025 "Infrastructure Development and Demonstration Project for Improving the Sustainability of Products such as Storage Batteries").
- Continuous participation in industry collaborative activities such as IPA/DADC and the Japan Automobile Manufacturers Association (JAMA).
