Aiming for a world where "GX (Green Transformation) is something people want to do," ByWill Inc. (Headquarters: Chuo-ku, Tokyo; President & CEO: Yuichiro Shimomura; hereinafter "ByWill"), a Climate Asset Developer promoting economic circulation utilizing environmental value, is pleased to announce that its collaborations with municipalities nationwide for the realization of carbon neutrality and other goals have surpassed 100 cases cumulatively.

We will continue to strengthen our partnerships with municipalities and regional financial institutions across the country and contribute to the creation of environmental assets as a Climate Asset Developer.

[Background and History of Surpassing 100 Partnerships]
ByWill has signed comprehensive cooperation agreements with municipalities across Japan and promoted initiatives aimed at realizing a decarbonized society.
By converting the CO2 reduction and absorption amounts generated through the introduction of local rich natural resources (such as forest resources), energy-saving equipment, and renewable energy into environmental value such as "J-Credits." By building a "local production for local consumption" model that returns this to local businesses, we are achieving not just environmental conservation but also the recirculation of funds into the regional economy (regional revitalization).
Furthermore, we have not only supported the creation of J-Credits but have also developed diverse decarbonization solutions tailored to the challenges and characteristics of each region, including support for the utilization of corporate hometown taxes and energy transition support in the agricultural sector. We have also deeply participated in promoting and socially implementing wide-area decarbonization policies at the prefectural level, not just for individual municipalities.
We are pleased that our vision and execution capabilities as a Climate Asset Developer have resonated with more municipalities, expanding our network of collaborations and reaching the significant milestone of "100 cases."

ByWill "supports the entire process from the creation of complex environmental value (such as J-Credits) to sales to companies, realizing a "regional economic circulation" where money flows back into the region."

Specifically, there are three major benefits (reasons for collaboration) for municipalities:

① Resolving Lack of Expertise and Resources (Thorough support for troublesome procedures)
Many municipalities have declared "Zero Carbon Cities" and possess potential in rich forests and renewable energy, but have not yet reached the stage of monetizing and utilizing them as "J-Credits." Even when attempting to do so, the application and registration processes are complex, require specialized knowledge, and demand significant manpower. ByWill provides comprehensive support for these cumbersome "creation processes," allowing municipalities to generate environmental value while minimizing the burden on their staff.

② Reliable Monetization (Strong sales network) - Not just "create and finish"
J-Credits are not complete once created; they only become "economic value" when matched with purchasing companies. ByWill has a strong network with companies nationwide (demanders) that are pursuing decarbonization. By partnering with ByWill, municipalities can avoid the "risk of unsold credits" and reliably monetize their regional environmental value.

③ Revitalization of the Regional Economy through "Local Production for Local Consumption of Environmental Value"
What ByWill values most is the "local production for local consumption of environmental value," where local companies and companies with ties to the region purchase regional environmental value. The revenue generated from credit sales is returned to the region, and is reinvested in further forest conservation, decarbonization initiatives, and regional promotion—this "virtuous cycle of environment and economy (regional economic circulation)" that can be designed together is highly praised by many municipalities.

[Message from President & CEO Yuichiro Shimomura]
"I am extremely pleased that we have been able to achieve the milestone of '100 cases' in our regional decarbonization journey alongside municipalities across the country. Through the creation of carbon credits, our company has promoted a mechanism that converts regional resources into environmental value without waste, circulates it as economic value, and further reinvests it in decarbonization. Decarbonization is by no means a cost, but an investment that brings new financial resources and vitality to the region. As a Climate Asset Developer advocating for 'making GX from what should be done to what people want to do,' we aim to implement this circulation model in all 47 prefectures and lead Japan's carbon neutrality."

[Future Outlook]
The "breakthrough of 100 municipal partnerships" is merely a stepping stone for ByWill. Leveraging the knowledge and experience gained from our past collaborations to the fullest, we aim to engage with all approximately 1,700 municipalities in Japan and support the realization of regional carbon neutrality.
While many municipalities are currently increasing J-Credit creation through "forests" and "LED replacements," we are not limited to being a specialized vendor handling only these limited areas. We will continue to expand carbon credit methodologies into diverse fields such as agriculture, livestock, marine resources, water heaters, solar power generation, EVs, and air conditioning, thereby weaving together the environmental value that lies dormant in regions.
Furthermore, going forward, we will actively utilize not only the framework of carbon credits but also corporate hometown taxes and various PPAs, and will jointly work on direct CO2 reduction within municipalities. By deepening our partnerships with municipalities and simultaneously advancing both the "evolution (deepening)" of relationships and the "horizontal expansion" nationwide, we will strongly promote the realization of a "world where GX is desired" and the construction of a sustainable regional society.
