TL;DR

We’re pleased to announce a strategic partnership with Carbon EX, operator of one of Japan’s largest carbon credit and emissions trading platforms.

Through this partnership, Sylvera’s world-class carbon ratings will be integrated into Carbon EX’s exchange platform, enabling Japanese corporations and institutional investors to trade high-quality carbon credits with unprecedented transparency.

Background of the Partnership

As the world’s fourth-largest economy, Japan is accelerating efforts toward achieving carbon neutrality by 2050. Over 1,500 Japanese companies have already set Science Based Targets (SBTs), and the government is reinforcing mechanisms such as the J-Credit Scheme to support emission reductions. 

However, challenges remain: the carbon credit market faces significant disparities in credit quality and asymmetric information, highlighting the urgent need for a transparent and trustworthy market infrastructure.

Carbon EX operates one of Japan’s largest carbon credit and emissions trading platform, supporting a wide range of corporations, municipalities, and project developers. By partnering with Sylvera - whose independent methodologies are regarded among the world’s most advanced - Carbon EX aims to establish a new benchmark that combines international quality standards with Japanese market transparency.

Partnership Overview

Under the agreement, Sylvera’s proprietary global carbon credit ratings will be fully integrated into the Carbon EX platform. This will allow users to view each credit’s environmental integrity and risk assessment in real time, empowering companies and investors to make informed decisions based on robust data.

The partnership will also make visible the quality of credits that has traditionally been difficult to assess, dramatically reducing uncertainty in the purchasing and procurement process. By combining Sylvera’s scientific, independent assessment capabilities with Carbon EX’s domestic network and trading infrastructure, Japanese corporations will gain greater access to verified, high-quality carbon credits. 

Meanwhile, project developers will enhance their credibility in the marketplace through internationally aligned evaluations.

Furthermore, this collaboration will enable transparent transactions on Carbon EX’s platform - replacing the opaque over-the-counter trading that has long dominated the market. As a result, the funds companies invest in purchasing carbon credits will reliably flow to high-impact climate action projects, substantially improving the trust and integrity of Japan’s carbon credit market as a whole.

“Japan represents one of the world's most sophisticated carbon markets, with corporations demanding the highest standards of project integrity and transparency, “ said Allister Furey, Co-Founder & CEO, of Sylvera. “Carbon EX brings unparalleled expertise in Japan's domestic carbon markets and deep relationships with Japanese corporations and project developers. Combined with Sylvera's scientific rigor and independent assessment capabilities, we're creating the gold standard platform for Japan's carbon market - one that can channel significant capital toward genuinely impactful climate solutions across Japan's industrial economy.

“Japan's carbon credit market has enormous potential, especially with the government's commitment to carbon neutrality by 2050 and growing corporate demand for high-quality domestic credits,” said Takayuki Kageyama, Co-CEO, Carbon EX Inc. “However, realizing that potential requires absolute confidence in project quality and market transparency. Sylvera's world-class ratings expertise, combined with Carbon EX's deep understanding of Japan's regulatory environment and market dynamics, creates a powerful ecosystem where high-integrity projects can thrive while bringing enhanced transparency, integrity, and liquidity to Japan's carbon credit market.”
