Bywill Inc. (Headquarters: Chuo-ku, Tokyo; President & CEO: Yuichiro Shimomura; hereinafter 'Bywill'), a company promoting an economic circulation utilizing environmental value with the goal of creating a 'world where people want to do GX', has concluded a customer referral agreement with Ryoki Kogyo Co., Ltd. (Headquarters: Kanazawa City, Ishikawa; President: Masakazu Kitagawa; hereinafter 'Ryoki Kogyo'). The two companies have commenced collaboration aimed at the 'creation' and 'procurement (purchase)' of carbon credits.
By bringing together Ryoki Kogyo's customer network and Bywill's expertise in creating and selling environmental value, the companies aim to circulate environmental and economic value associated with the renewal and optimization of air conditioning equipment across the country, thereby contributing to the achievement of carbon neutrality in Japan.
## Background of the Agreement
Ryoki Kogyo has focused on energy saving and ZEB (Net Zero Energy Building) realization for buildings, contributing to the optimization of customers' energy through the renewal of air conditioning equipment and other means. In recent years, as requests for decarbonized management in companies have become stronger, there is a demand for support that goes beyond mere energy-saving proposals and includes more in-depth 'utilization of environmental value'.
On the other hand, Bywill advocates the 'circulation of environmental and economic value' and has numerous achievements nationwide as a company that provides end-to-end support from the creation to the distribution (trading) of J-Credits.
Under these circumstances, the companies believed that by combining their respective strengths, they could support client companies' decarbonization more effectively, leading to this partnership.
## Details of Collaboration
Through the design and construction of air conditioning, plumbing, and sanitary facilities, Ryoki Kogyo contributes to improving office comfort and the environment of production sites. Through this partnership, Ryoki Kogyo will introduce Bywill to client companies according to their decarbonization needs from the following two perspectives.
### Support for the 'Creation' of Environmental Value
Ryoki Kogyo will introduce corporate customers who are upgrading to highly energy-efficient air conditioning equipment to the J-Credit creation project operated by Bywill (membership organization name 'Air Lab', etc.).
The J-Credit creation project 'Air Lab' operated by Bywill adopts a 'programmatic type' that aggregates multiple reduction and absorption activities. This makes it possible even for small and medium-sized businesses, for which credit generation on their own is a high hurdle, to generate and monetize the CO2 reduction amount from equipment upgrades as 'environmental value (J-Credits)'.
The J-Credits created through 'Air Lab' will be sold by Bywill to carbon credit consumer companies nationwide.
### Support for the 'Procurement' of Environmental Value
Furthermore, Ryoki Kogyo will introduce Bywill to customers who need to purchase carbon credits to promote decarbonized management and realize carbon neutrality. Bywill handles domestic and international credits and certificates, and can procure and provide the optimal credits tailored to customer needs.
Through this collaboration, the companies will support the 'creation of environmental value' accompanying the renewal of air conditioning equipment in companies and local governments nationwide, and distribute the created credits to consumers. This will generate a circulation of environmental and economic value, aiming to contribute to achieving carbon neutrality in Japan.
