Carbon EX Inc. has entered a strategic partnership with Sylvera Ltd., the world’s leading carbon credit rating and data provider. The goal is clear, to build a new kind of carbon market in Japan that prioritizes transparency, credibility, and quality. By integrating Sylvera’s carbon intelligence platform into the Carbon EX exchange, the companies plan to make high-quality carbon credits easier to verify and trade.
Japan’s endeavor for 2050 carbon neutrality is going on in full swing. More than 1,500 companies are already committed to science-based targets, moreover, the government is supporting systems like the J-Credit Scheme, subsequently, the market is rapidly growing. Yet, the shortcomings are clear. There is a big difference in carbon credit quality, and the absence of trustworthy information complicates the situation for purchasers who want to make sure about their choices. That is where this partnership steps in.
Carbon EX already runs one of Japan’s largest carbon credit and emissions trading platforms. By teaming up with Sylvera, which brings world-class independent evaluation technology, the company aims to raise the bar for both transparency and quality in Japan’s carbon market.

Here are what changes. Sylvera’s data will be embedded into the Carbon EX system, letting companies and investors instantly check the environmental integrity and risk of each carbon credit before they trade. That means fewer blind spots and smarter decisions. The integration also makes the quality of each credit visible in real time, cutting down uncertainty during buying and procurement.
The partnership will also make the entire trading process more transparent. Until now, most carbon credit deals in Japan have been done through private, bilateral transactions. With this integration, trades can happen openly on the Carbon EX platform, ensuring that money spent on carbon credits actually reaches projects that deliver real climate impact.
By combining Sylvera’s scientific assessment standards with Carbon EX’s strong domestic network, the collaboration opens up access to high-quality credits for Japanese companies and boosts confidence for project developers. It sets the foundation for a fairer, more reliable carbon market where trust, data, and impact finally align.
