Carbon EX Co., Ltd. (Headquarters: Minato-ku, Tokyo, Representative Directors: Kohei Nishiwada, Shunsuke Takeda, hereinafter "Our Company") has supported Sunayama Shoji Co., Ltd. (hereinafter "Sunayama Shoji"), a company based in Ishikawa Prefecture that develops industrial equipment and energy-related businesses, in completing the registration of J-Credits for solar power generation facilities.

In this initiative, our company provided consistent support throughout the process from organizing the creation possibilities to registration for J-Credit creation utilizing the environmental value of solar power generation facilities owned and proposed by Sunayama Shoji.

Background of J-Credit Utilization in the Detached Housing Business

The J-Credit system is a mechanism certified by the government for greenhouse gas reduction amounts generated by the introduction of renewable energy equipment and energy-saving activities, which can be utilized as environmental value. On the other hand, utilizing the system requires specialized knowledge and practical response, and the hurdle for utilization is currently high, especially for small and medium-sized enterprises.

Sunayama Shoji is a locally based industrial trading company that has provided a diverse range of products and services to corporations, mainly in the manufacturing industry, and general households, based in Ishikawa Prefecture. While expanding its business domains to include solar power systems and environmental equipment, in addition to industrial machinery, high-pressure gas, and housing-related equipment, it has focused on the issue that customer companies are not fully utilizing the environmental value generated by reducing CO2 emissions through solar power.

In reality, there are many cases where emission reductions do not lead to profits and are not sufficiently used for PR or sales proposals. Even when wanting to further promote renewable energy introduction, the burden of additional investment is often a barrier. Based on this situation, Sunayama Shoji decided to seriously consider utilizing the J-Credit system as a mechanism to monetize CO2 reduction value while leveraging the strengths of its own solar power generation business.

Key Points of J-Credit Registration Support by Carbon EX

Our company provided the following support for the approval of this project.

1. Organizing the creation scheme using solar power generation facilities and application support

We provided consistent support, from organizing the creation possibilities under the J-Credit system for a wide range of solar power generation facilities, from industrial to residential use, to organizing the necessary considerations for registration applications, document creation, and handling examinations.

2. Supportive practical support to compensate for lack of specialized knowledge and personnel

The J-Credit system involves highly specialized tasks such as organizing facility information, calculating emission reduction amounts, and preparing application documents. Our company supported the creation of a system that makes it easy for Sunayama Shoji to execute its first credit creation project by providing information to deepen understanding of the system, assisting with the preparation of application documents, and providing templates for study session materials.

Future Outlook

Through this J-Credit registration, Sunayama Shoji has established a system capable of proposing everything from the introduction of solar power generation facilities to the visualization and crediting of CO2 reduction amounts. This allows for proposals that include the creation and utilization of environmental value, evolving the solar power generation business from "goods sales" to "environmental value provision". Furthermore, by incorporating CO2 reduction as a revenue opportunity into sales activities, they can now present new added value to customers. Their relationships with customers are expected to expand from one-off equipment installations to long-term partnerships.

Going forward, Sunayama Shoji will steadily promote ongoing projects within Ishikawa Prefecture and, with an eye toward nationwide expansion in the future, aims to become an entity that simultaneously supports the decarbonization and profitability of regional companies. Our company will also continue to support the creation of projects utilizing the J-Credit system and contribute to the realization of a decarbonized society where environmental value and economic value circulate.
