Japan’s largest bank collaborates with KlimaDAO on carbon credit marketplace
Japan’s largest bank, MUFG, has teamed up with KlimaDAO Japan, the provider of a digital reserve currency backed by carbon credits, to explore the use of the JPYC stablecoin for settling tokenized carbon credit transactions on the Progmat blockchain platform.
Settlement on Progmat
Progmat provides the infrastructure to enable the issuance of various stablecoins. Last September, MUFG announced a collaboration with Binance geared towards stablecoin issuance.
The JPYC stablecoin, operational since 2021, functions as a prepaid money instrument, similar to a prepaid card, due to its existence before Japan’s stablecoin legislation. Under new regulations, JPYC can either obtain a money transmitter license or issue a trust-style stablecoin with a bank like MUFG acting as the trustee for the stablecoin's reserves. Last year, JPYC formed a partnership with MUFG implicating the use of the Progmat platform.
This partnership, along with the involvement of Kansai Electric subsidiary Optage as the integration partner, sets the stage for the KlimaDAO stablecoin experiments. Optage will provide the corporate infrastructure required to manage the carbon credits added to the blockchain and provide a means for funds settlement to be achieved via bank transfer. Through the use of various local stablecoins for the purpose of settlement, it’s hoped that improved liquidity on a global basis may be achieved.

Initially recognized for making tokenized carbon credits accessible on public blockchains, KlimaDAO's functionality extends beyond this. The organization also offers the capability to retire credits. Last year, KlimaDAO expanded its reach by launching Carbonmark, an enterprise-focused marketplace.
This platform, which utilizes blockchain technology, namely Polygon, and smart contracts, offers a user-friendly experience by integrating traditional payment methods like bank transfers and SAP integration.
J-Credits
Japan operates a national scheme known as J-credits, and the Tokyo Stock Exchange has introduced a secondary market for these credits. J-credits are designed to certify the amount by which greenhouse gas emissions have been reduced through the use of carbon sinks in Japan. However, the volume of J-credit transactions remains low, reflecting the broader state of Japan's voluntary carbon market.
KlimaDAO aims to address this by launching the KlimaDAO Japan Market, simplifying the process for domestic companies to purchase and utilize carbon credits. This initiative will involve tokenizing J-credits, referred to as D-Carbons.
Andrew Bonneau, KlimaDAO co-founder, outlined on X that “@KlimaDAO is in a unique position to facilitate an efficient J-Credit market on chain, while serving as the base infrastructure for integrating these assets with 3rd party services.” While the initial phase will use traditional bank payments, the ultimate goal is to transition to using stablecoins, particularly the JPYC stablecoin.
Norbert Gehrke, an observer of developments within the Japanese fintech scene, outlined on Medium that the Japanese carbon credit market is likely to reach three trillion yen ($19.15 billion) by 2030. Meanwhile, the global carbon credit market has a current value of 39 trillion yen ($249 billion).
KlimaDAO Japan has mentioned the use of a permissionless blockchain for this initiative but has fallen short of confirming that the Polygon network will be relied upon. Japan has several homegrown blockchains, which might be considered for this project.
At the time of writing, the KLIMA token had risen 31% over the course of the previous 24 hours, with a unit price of $3.53 according to CoinGecko.
