Carbon EX Inc. (Headquarters: Minato-ku, Tokyo; Co-CEOs: Kohei Nishiwada, Shunsuke Takeda; hereinafter 'the Company') is pleased to announce the commencement of system integration with the 'Tokyo Carbon Credit Market' operated by the Tokyo Metropolitan Government. Through this integration, a portion of the credits handled by the Company's carbon credit and emissions trading platform 'Carbon EX' will become available for purchase on the Tokyo market, improving convenience for carbon credit utilization, particularly for companies based in Tokyo.
## Background of API Integration
Toward the realization of carbon neutrality by 2050, companies are being required not only to visualize and reduce greenhouse gas emissions but also to strengthen external disclosure and accountability. In Japan specifically, with the full-scale operation of the Green Transformation Emissions Trading System (GX-ETS) scheduled for April 2026, the use of carbon credits is evolving from a mere offset method into a critical strategic option integrated with management decisions.
On the other hand, the credit market has faced challenges such as differing trading processes for each certification system, fragmented information, and the difficulty of ensuring reliability. These issues have continued to pose a high barrier for SMEs in particular. To address these challenges, the Tokyo Metropolitan Government has established its own platform, the 'Tokyo Carbon Credit Market,' where domestic and international carbon credits can be easily traded, thereby supporting the decarbonization efforts of Tokyo-based companies.
Against this backdrop, the Company has initiated integration with the market to further improve liquidity and strengthen convenience in the carbon credit market.
## Advancing Carbon Credit Distribution through API Integration
With this integration, a portion of the credits available on our platform 'Carbon EX' can now be purchased on the Tokyo Carbon Credit Market via API. This expands procurement options, creating an environment where companies can procure credits more efficiently and flexibly.
In particular, by connecting our diverse credit lineup—one of the largest in Japan—with Tokyo's infrastructure, we expect an improvement in the liquidity and transparency of credit distribution. As a result, companies will find it easier to select the optimal credits based on their own decarbonization strategies and disclosure needs, further enhancing the effectiveness of carbon credit utilization.
This initiative holds great significance in that it cross-sectorally integrates the often fragmented credit market by connecting a private platform with public infrastructure, thereby increasing convenience at the practical level.
## Future Outlook
Moving forward, the Company will use this integration as a starting point to further advance the distribution infrastructure for carbon credits. As compliance with systems like GX-ETS progresses, it will become increasingly important for companies not only to procure credits but also to understand price trends and utilize them strategically.
In light of these environmental changes, the Company will further strengthen its collaboration with local governments and financial institutions to promote the construction of an ecosystem that integrally supports everything from credit creation and procurement to trading and management. Furthermore, by expanding data integration using APIs, we will contribute to improving market transparency and enhancing sophisticated decision-making.
The Company will continue to contribute to the development of the carbon credit market, aiming for the realization of a society where companies can balance environmental response with business growth.
