“Over the years we’ve invested significantly in our field data team - focusing on producing trusted ratings. While this ensures the accuracy of our Ratings, it doesn’t allow the scale across the thousands of projects that buyers are considering.”

ByWill Inc. is one of Japan's leading J-Credit developers. Recognized as one of eight designated J-Credit providers in Japan, the company supports the full lifecycle of carbon credit generation - from project methodology selection across more than 70 approved J-Credit methodologies spanning energy efficiency, renewable energy, agriculture, and forest management - through to buyer matchmaking and monetization.
As ByWill looked to prove the value of its J-Credits and expand its business across both the voluntary carbon market (VCM) and compliance credit markets - the company needed a way to bring the global, high standards of rigor and transparency to J-Credits that the VCM had already established.
Using Sylvera, ByWill can validate its J-Credit quality, put a clear value on its credits, and support the growth of its credit and consulting services.
The Challenge
Showing that J-Credits aren't all worth the same
J-Credits are primarily designed for domestic regulatory compliance. But depending on origin, methodology, project type, and vintage, some J-Credits are worth more than others.
With a growing track record of high-value, long-term credit sales, ByWill needed a way to prove the quality and premium price of certain J-Credits.
Unlocking this extra value required the ability to explain, measure, and standardize that premium in a way the market could trust. ByWill needed more advanced data and platform capabilities than what was available in the J-Credit market alone - one already established in the VCM space, where quality frameworks and transparency standards are more mature.
And, as the value of carbon credits is expected to vary more and more depending on who's buying them and which compliance schemes they're being used for, ByWill wanted to connect Japan-specific value with globally recognized rating standards.
The solution
ByWill has a think tank division and a brand consulting division. While the company was already building a track record and advancing data analysis and the utilization of carbon credits for clients, it expects the partnership with Sylvera to further strengthen these capabilities.
A platform spanning VCM and compliance markets, built on quality and transparency
ByWill selected Sylvera for its comprehensive expertise, ratings, and data across the VCM, and its ability to support the needs of a company operating across both J-Credit and voluntary markets.
Building a deeper understanding of quality for J-Credits
To build a deeper understanding of carbon credit ratings quality criteria, ByWill uses Sylvera to validate the quality of its J-Credits. This provides a more rigorous, externally credible way of assessing the credits it develops and brings to market.
Connecting local value with global rating standards
Sylvera's established global frameworks, understanding of methodologies, and Market Intelligence helps ByWill demonstrate and formalize the value of J-Credits. Linking local market nuance with globally recognized ratings benefits both developers bringing credits to market, and buyers understanding the value.
Market Intelligence for an expanding business
As ByWill's VCM and compliance credit business grows, several specific platform capabilities factored into its decision to adopt Sylvera:
- Accurate and reliable pricing data, supporting confident commercial decision-making
- Explainable forward price estimates, giving ByWill transparency into how forecasts are derived
- Supply and demand forecasts, supporting strategic planning across both VCM and compliance markets
- Country Profiles, enabling cross-country comparison as ByWill's business extends beyond Japan
- Buyer Directory, providing insight into global retirement trends among buyers
The impact
Building the foundation for credit and consulting growth
Through its partnership with Sylvera, ByWill grows its credit business and consulting services by using standardized data across the carbon markets.
1. A credible way to assess J-Credit quality
By validating J-Credit quality against Sylvera's standards and market data, ByWill can offer clients and buyers a level of quality assurance that wasn't previously available in the J-Credit market.
2. Greater transparency in J-Credit pricing
ByWill has a clear picture of the J-Credit and VCM markets - helping justify premiums that reflect real quality differences, rather than a flat, one-size-fits-all price.
3. A platform to support growth across markets
With a comprehensive market data view across both VCM and compliance markets, ByWill is positioned to grow its credit and advisory services without being held back by tools designed for just one market.
4. A contribution to Japan's carbon market development
By connecting local value with global rating standards, ByWill is helping to reinvigorate Japan's carbon market, benefiting both the developers it supports and the buyers it serves.
